5 California Solar Initiative
Agenda Item # 5a TRUCKEE DONNER Memorandum To: Board of Directors From: Kathleen Neus, Project Manager Date: November 14, 2007 Subject: SB-1; California Solar Initiative 1. WHY THIS MATTER IS BEFORE THE BOARD With the enactment of SB-1, the California Solar Initiative, all local publicly owned electric utilities within the State of California, must prepare, adopt and implement a solar program to encourage its customers to install solar energy systems. SB-1 is an unfunded state mandated program to begin January 1, 2008. Objectives: 5. Manage the District in an environmentally sound manner. Goals: 5.3 District will support a program of distributed generation within its Service Area 5.4 District will conduct its business in an environmentally lawful manner. 5.5 District will maintain a program of energy and water use efficiency. 5.6 District will seek to minimize any negative impact of its operations on the environment. 2. HISTORY As part of Governor Schwarzenegger's Million Solar Roof Program, all local publicly owned electric utilities must adopt, implement and finance a solar initiative program by January 2008. SB-1 imposes a state mandated local program that requires the District to make program information available to its customers. The District must use ratepayer funds and expend $1,773,408 over ten years; the dollar amount was set by the California State Legislature. The dollar amount is based upon the District's percentage of the total statewide load served by all local publicly owned electric utilities within California. In addition, SB-1 establishes specific requirements for local programs, including system incentives and a minimum rebate amount. In May of 2007 the North Lake Tahoe-Truckee Leadership Program completed "A Discussion of Senate Bill 1 and a Review of Photovoltaic Products and Installers in and for the Tahoe-Truckee Area" (Appendix H). The paper provides information regarding solar products that can be used in new and existing residential structures. The group also used the California "Go Solar' website www.findsolar.com , which gives an idea of price, savings, system size, roof space required and installation costs. There is also a link to find products and installers (local installers Section 4.0 pages 14-17) within an identified distance of the project site i.e. 100 miles of the PV location. The Board hired Efficiency Services Group in June of 2007 to help the District to prepare and implement the District's Solar Program as required by SB-1. Efficiency Services Group gave a presentation on a draft solar program at October 17, 2007 Board Meeting. 3. NEW INFORMATION At the October 17th board meeting the Board asked staff to answer some questions. Included with this report are pages that should answer the Boards questions. The questions were to be Truckee specific, the questions are answered as specifically as possible. • What are other utilities doing (Appendix A) • Feasibility of a solar installation (Appendix B) • Shading analysis / location on property (Appendix C) • Examples of rebates (Appendix D) • Energy efficiency connected to rebate (Appendix E) • Snow Loads (Appendix F) • Installation on metal roofs (Appendix F) • Condo and HOA (Appendix G) Answers and supporting documents are included at the end of the staff report in order of the questions listed above. Doug Boleyn of Efficiency Services Group will be at the November 19th Board meeting to present the Board with a written Solar Program (Helios Array Program; Appendix I; Forms Appendix J). The program meets all required parameters as set forth in SB-1, The California Solar Initiative. At this time staff is seeking board approval of the written program with the final copy to include the Board specified rebate amount ($4.00). 4. RECOMMENDATION Adopt the Truckee Donner PUD rebate in the amount of $4.00 a kilowatt installed; approve the Solar Program (Helios Array Program) as written with the adopted rebate amount. The program will be brought back to the Board in December of 2008 to discuss problems or ways to improve the program. Alan eneral Services o n Ulrich, Interim bM 5. SOURCE OF FUNDING (if applicable) for projec or quipment Funding for Efficiency Services Group will be provided by the Electric Department and reimbursed by the surcharge collected on customer bills (MO 2007-73). Funding for the SB-1 Solar Initiative has to be determined; the Board needs to decide on how much and how to charge for the funding. 6. BOARD AUTHORIZATION TO TRANSFER FUNDS There is no request at this time.

Other taxes and surcharges may be applied to your utility bill. We suggest you review a recently utility bill and change the "Assumed Electric Rate", above, as needed to better match your situation. You may have other metered-rate options with your utility. Options such as Tiered billing rates, Time-Of-Use (TOU) metering, and Net-Metering, if available, can help reduce the system size you need to provide a net-zero energy bill. Sometimes people also reduce the size of their solar system to accommodate planned improvements in their building's energy efficiency, or to match a budget and/or the available space for installing a solar system. Energy production from a solar electric (PV) system is a function of several factors, including the following. Our assumptions are: Factor Assumption Assumed solar availability: As per Solar Radiance Solar resources chart Soiling or contamination of the PV Clean, washed frequently: 100% design sunlight panels transmission Temperature 25C, calm wind System configuration Non-battery (battery or non-battery) Orientation to the sun tilted at your latitude, full sun Shading None PV Energy delivered 85% as % of manufacturers rating Wiring & power point tracking losses 7% (93% delivered) Inverter Efficiency 90% Total Energy Delivered 85% x 93% x 90% = 71% Energy Efficiency: Improving your building's energy efficiency will reduce the system size you need to attain a "net-zero" energy bill. Tiered Rates: Often people are paying a "Tiered" rate for their electricity. This is a higher rate (higher than the "Base" rate) for electricity charged when a home or building uses more that a "Base" amount allocated for the building. Installing a solar system will reduce your electrical demand from the utility. This can result in a lower utility rate because you stay within the "Base" rate level. In this case, the more expensive "Tiered" rate electricity is eliminated, reducing your average electricity rate. TOU Metering: Many utilities offer Time-of-Use (TOU) meters. This allows the price of electricity to vary by time of day (called "Peak" or "Off-Peak" periods) and by season (usually http://www.findsolar.com/content.php?page=rightfonne&subpage=submitdata&action=initialize&type=... 11/14/2007 FindSolar.com -rightforme submitdata Page 4 of 5 "Winter" verses "Summer" rates). If TOU metering is offered by your utility, a solar system may result in additional savings. This is because peak (more expensive electricity) rates often occur during the daytime. This is usually when a solar system is producing the most output, thus reducing your demand for peak-rate electricity from the utility. Most utilities do charge for the purchase and installation of a time-of-use meter (normally a few hundred dollars). We have assumed the cost for this is part of the "Estimated Installation cost" shown above. Net-Metering: With Net-Metering, surplus electricity generated by your renewable energy system will be credited back to your utility account. So if your solar system makes more electricity than you are using, the "meter spins backwards". You are not actually "selling" electricity, since in most states the utility will not reimburse you for excess electricity. But, if your utility offers "Net-Metering" you may be able to get credit for electricity provided back to the grid during peak periods. Combined with TOU metering, Net-Metering can result in multiplied savings since your electricity account may be gaining electricity credits during the time of peak utility rates -- Think of a hot, sunny summer day ... your solar system is producing power, spinning your electric meter backwards, and supplying the grid with electricity to run other people's air conditioners -- you're "spinning back" cost at peak rates! That's the savings power of Net-metering, combined with TOU rates. Solar Power "Fixes" Energy Costs: The cost of sunshine is free. While the sun rises every morning, the cost of sunshine does not. Utility rates, on the other hand, tend to rise steadily in cost. So, the value of your savings from a solar system are likely to increase as time goes on. If you are on a fixed income (e.g. nearing or in retirement) this may be of particular interest to you. THE COST TO GO SOLAR This is only an estimate based upon many assumptions and limited data entered by you: Installation costs can vary considerably. The cost to purchase and install a complete grid-tied solar photovoltaic (PV) system on a residential home is typically $8-$10 per watt (as further defined in the table, below). This does not include the cost of options you may select, such as battery backup power storage, or the costs of building preparation work, like new shingles. Costs can also be higher if you add other features or have special installation needs (such as application over tile roofing) or you choose to use special mounting systems (such as sun tracking systems). Other factors may also affect price, including, but not limited to, your location, the building condition, type and location, its wiring, and warrantees offered.

The PV array needs to be located where it will have access to the sun and where it will not be in the shadow of other building elements (e.g., facades and parapets, mechanical/ plumbing elements (including vent pipes and flues), and landscaping (when at full growth). Shading constraints from neighboring properties are common as well, especially given the urban setting for many commercial and multifamily buildings. When considering possible shade problems, look both at your site and at buildings that shade your site. • Not all shade on a site is a problem - remember that if you will be mounting your PV array on the rooftop of a 5-story building, then the 5-story neighboring building that shades your lot at ground level will not be a shade problem for your system. • Particularly for nearby property to the South, consider whether the site will be developed with a structure taller than your own. Full or partial shading of the panels inhibits the production of electricity... "because the solar cell with the lowest illumination level determines the operating current for all of the cells wired in that series." (Energy Design Resources web site) Solar professionals describe this effect of partial shading as similar to kinking a garden hose, where the reduced size of the opening allows only a small amount of water through. Because of this effect, a relatively small amount of shading can create a disproportionate reduction in electricity production. Note: Thin film PV products are less affected by shading and overcast days than are crystalline PV modules. U.S. Department of Energy - Energy Efficiency and Renewable Energy Consumer's Guide to Energy Efficiency and Renewable Energy Siting Your Small Solar Electric System Both the orientation and tilt of your solar panels or photovoltaic (PV) modules will affect your solar electric system. You and your contractor should consider both factors while evaluating your site's solar resource and sizing your system. Orientation PV modules should be oriented geographically to maximize the amount of daily and seasonal solar energy that they receive. In general, the optimum orientation for a PV module in the northern hemisphere is true south. However, your modules can face up to 450 east or west of true south without significantly decreasing its performance. If you plan to mount the modules on your roof, you'll also want to consider these factors: • Roof orientation and condition • Local landscape features that shade the collector daily or seasonally • Local weather conditions (foggy mornings or cloudy afternoons) that may affect the optimal orientation and subsequent electricity production of the PV modules. To be eligible for some rebates, your system must be unshaded between certain hours during certain times of the year. Some states also have laws that establish your right to protect your solar access through the creation of a solar easement. If a rooftop can't be used, your solar modules can also be placed on the ground, either on a fixed mount or a "tracking" mount that follows the sun to orient the PV modules. Tilt Most PV modules are mounted flat on the roof, and so have the same tilt as the roof. Although the optimal tilt angle for your modules is an angle equal to your latitude, fixing the PV modules flat on an angled roof is generally not a problem. However, because most roofs are pitched at an angle less than the latitude, you and your contractor will need to factor your roof angle into the performance calculations when sizing your system.

Place the Solar Pathfinder (SPF) on the ground in the location of the future PV panel. Using the grease pen supplied, trace around the shading objects directly onto the clear plastic angle estimator (also supplied with the SPF). The SPF clear angle estimator is write-on/wi a-off. 2. Type into the spreadsheet the expected height (to the bottom of the panels) that the PV panels will be mounted at in the yellow shaded box with the "P" (Panel Height) above it.

Type this measurement into the spreadsheet in the blue shaded box with the "D" (distance) above it. 4. Use the clear angle estimator in the SPF at ground level to get the altitude (Angle 1) of the object shading the spot. [The altitude is the angle above the horizon — shown as concentric circles on the angle estimator.] Find that angle measurement (Angle 1) in the red column. For this example, we will only work with the tree shown between 10-35 degrees West. Our example shows angle 1 (at the tip of the tree) to be 50 degrees (beside the ©). Your new angle (Angle 2) at the new height (P) will be in the green column to the right of your original, ground-level angle measurement (Angle 1). Our example shows angle 2 to be 26 degrees. 5. Plot the Angle 2 on the clear angle estimator at the corresponding azimuth. [The azimuth is the angle east or west of due south —shown as rays from the center of the angle estimator.] NOTE: Any new Angle 2 measurements that are negative indicate that the object will then be below the new heights' horizon and will cause no shading. In our example, the tip of the tree stays at 23 degrees W. for the azimuth having a new angle of 26 degrees above the horizon — shown with yellow line. At azimuth 15 degrees West, the angle 1 is 45 degrees, making angle 2 equal 17 degrees. At azimuth 30 degrees West, angle 1 is 40 degrees, making angle 2 equal 8 degrees. 6. You will need to repeat steps 3, 4, & 5 for each shading object (different shading objects will be located at different distances from the Pathfinder) in question. 7. Place the clear angle estimator with its new Angle 2 measurements for the given height (H) on top of you latitude-specific sunpath diagram to see if the shading estimated at the new height will intersect the sunpath. In our example, the new proposed F° height's shading (marked in yellow) will barely touch the sunpath for December and January around 1:15pm at this latitude.

In the California Solar Initiative Program Handbook, Section 2.3 Energy Efficiency Requirements it states "beginning January 1, 2007 all existing residential and commercial customers will be required to have an energy efficiensy audit conducted on their existing home or building if they chose to apply for a solar incentive. The acceptable audit protocals will consist of an on-line audit or telephone audit provided by the Utilities." An audit is required but the bill does not state that energy efficiency measures must be completed in order to receive the solar rebate. From what I have heard from others is that requiring energy efficiencies is a good idea but tying the rebate to energy efficieny is making an all ready expensive project even more expensive. Attached is Section 2.3 Energy Efficiency from the Handbook. 2. Divide the new estimated annual kWh by (8760 x CEC-AC rating)to find the capacity factor. 3. Divide the capacity factor from#2 by the prevailing capacity factor assumed for a given step to get a proxy Design Factor. 4. Find the system size (kW)by multiplying the Design Factor from #3 times the CEC-AC size above This calculation would allow the Program Administrators to estimate annual production from the EPBB Calculator that adjusts for performance of non-crystalline PV technology. 2.2.5.1 System Sizing Based on Future Load Growth In the case of Applicants with new or expanded sites with no electric bill history or where the existing electric bill does not reflect the Applicant's expected expanded consumption, the Applicant must include an estimate of the expected expanded consumption. An engineering estimate is preferred. The engineering estimate must include the appropriate substantiation of the forecast of the Host Customer Site's annual energy use (in kWh) if the generating system size is based on future load growth, including new construction, load growth due to site expansion or other load growth circumstances. Suggested methods of demonstrating toad growth include Application for Service with corresponding equipment schedules and single line diagram; building simulation program reports such as eQUEST, EnergyPro, DOE-2, and VisualDOE; or detailed engineering calculations or lists of equipment with corresponding equipment schedules. The Program Administrator will verify the load growth predicted before moving forward with the Confirmed Reservation Notice. Systems that are 5 kW or less, are assumed to be in compliance with being sized to serve on-site electric load and do not require substantiation. 2.3 Energy-Efficiency Requirements Beginning January 1, 2007 all existing residential and commercial customers are required to have an energy efficiency audit conducted of their existing home or building if they chose to apply for a solar incentive. The acceptable audit protocols will consist of an on-line audit or telephone audit provided by the Utilities. The Utilities may also provide additional audit tools available for customers in addition to the on-line and phone audits. Customers are responsible for submitting a copy of a completed energy efficiency audit to the CSI Program Administrator with their solar incentive application. Non-Utility Providers: Non-utility entities may also provide audits at the expense of the customer. At a minimum, the provider must perform an online or phone audit. Califomia Solar Initiative Program Handbook 17 Envelope Mechanical Lighting Outdoor Lighting ENV-1-C MECH- 1-C LTG-1-C OLTG-1-C Only compliance documents completed by persons who are Certified Energy Plans Examiners (CEPE) by the California Association of Building Energy Consultants (CABEC) are accepted. The above compliance documents must also be generated by one of the Energy Commission's approved Title 24 software programs: Micropas or Energy Pro. Residential New Construction: ■ Residential New Construction projects (single family home, custom homes and multifamily buildings) are currently handled by the California Energy Commission (CEC) under the New Solar Homes Partnership. Please contact the CEC for applications and program requirements at www.GoSolarCalifornia.ca.aov. In 2007, the California Energy Commission will develop eligibility criteria and conditions for receiving future CSI incentives, including new energy efficiency requirements. Please see http://www.eneray.ca.aov/sb1/meetings/index.html for more information. 2.4 Warranty Requirements In 2007, all systems must have a minimum 10-year warranty provided in combination by the manufacturer and installer to protect the purchaser against defective workmanship, system or component breakdown, or degradation in electrical output of more than fifteen percent from their originally rated electrical output during the ten-year period. The warranty must cover the solar generating system only, including PV modules (panels) and inverters, and provide for no-cost repair or replacement of the system or system components, including any associated labor during the warranty period. Self-installed systems must have a minimum 10-year warranty on the equipment to be installed to protect the purchaser against breakdown or electrical output degradation of major system components. In this case, the warranty need not cover the labor costs associated with removing or replacing major components because any repairs would be done by the self-installer or at the self-installer's expense. For the 2007 program year, meters must have a one-year warranty to protect against defective workmanship, system or component breakdown, or degradation in electrical output of more than fifteen percent from their originally rated electrical output during the warranty period. On or before January 1, 2008, the warranty requirements will be increased to a minimum of 5 years for meters, unless the Energy Commission establishes alternate requirements. Proof of warranty can be demonstrated in the executed solar contract or power purchase agreement. California Solar Initiative Program Handbook 19 APPENDIX F — Snow Loads, types of roofs Snow Loads The biggest problem is that the solar panels are made of glass which is a concern with the amount of snow sitting on the panels. The panels do not necessarily have to apply to the building codes as being able to with stand a specific snow load. The installation would not typically be flat in the Truckee area. A homeowner or business should expect to have to remove snow from the panels if need be. Should the panels be installed on the roof there will be a slope, with enough slope to shed most of the snow if not all and the same with a pole mounted system. Roof Types The question was raised is the installation of a solar system amenable to metal roofs. In Truckee roofs are typically metal, composition shingle, wood shingle or shake. There are solar tiles that are specifically designed for slate roofs and tiles that weave nicely with composition shingles. With metal or any type of roof the biggest concern is the roof penetrations. The installer will need to be sure that all penetrations are water tight which is a requirement everywhere. A concern with metal roofs is the shedding of the snow. Could the shedding snow take out the solar installation; most definitely but one would hope that one the installation was done correctly, two if the snow is that heavy the homeowner would be responsilbe to remove the snow prior to the snow becoming an issue. APPENDIX G — Condo and HOA Condo and HOA A TDPUD customer asked how can they install a solar system when the system is prevented by the Home Owners Association. I have inclued a three page memo on California Condo and HOA Law. The short answer is " the association may not prohibit systems — but may provide reasonable limitations."

In today's world, owners are, by their own initiative, seeking to be environmentally conscious. Outside clothes drying is coming back strong (we already talked about this in a separate blog). Solar installations are in vogue. One can place anything on their own home or in their own yard, but be careful if you are in a development where architectural approval is needed for changes to the exteriors of the buildings or erection of things on the roof or common area or other areas. Why? Because you may go out and spend a lot of money for something you cannot install. This is what California law says on the subject, and some commentary: If you purchase a solar system without checking first with the HOA Board and getting approval of a system and placement of it, the installer will probably recommend a roof system. The owner in a condo or townhouse homeowner's association does not own nor maintain the roof, so the association has an interest on what might be placed on it. So, the Association has a say in what might be installed (or not). Some HOA boards have been forward-thinking and have a policy on solar installations explaining what is acceptable. Those that do head off many disagreements. Others do not even know what options there are and so owners go ahead and do whatever they want, driving the board crazy. it's like having a satellite dish policy. If the owners are told what is acceptable, when they shop, they will likely have that acceptable installation with them and the solar (or satellite dish) salesperson will not be able to tell them they should purchase something else (usually more expensive). People are mostly like sheep - reallyl - The majority of people tend to follow, not lead, and the average person does not want to cause trouble if they can avoid it, so giving written guidance to owners tends to set boundaries that are accepted. Sometimes, owners just do not like the fact that the Board has any say at all so they do not ask for approval. Some owners get themselves into a dilemma by signing a contract for an expensive system and of course, that results in more incentive to fight for it. The limitations that association may impose on solar systems were found to be reasonable by the legislature when Civil Code Sections 714 and 714.1 were approved. The law won't allow an Association to prevent any solar installations, but does allow associations certain controls. One might ask why should this be?The answer is so that aesthetics and maintenance issues that may arise may be addressed (such as allowing the same or similar systems so that aesthetics are consistent). Certain systems may allow for reasonable maintenance of the roof and removal of the systems when roofs are replaced. And of course, if the roofs are the roofs, walking on them and installing systems can break tiles, one has to know how to walk on the tiles to keep from breaking http://www.communityassociations.net/cacondoguru/archives/2007/07/solar energy_wh.html 11/1/2007 California Condo & HOA Law: Solar Energy - What Are The Trade-Offs? What Do You Need to ... Page 2 of 3 them. Some roof warranties may be adversely affected or even voided unless the roofing contractor installs or can send a person up to supervise installation of a solar system. There is more at risk in a solar installation than the owners' ability to facilitate solar power (which of course is also an important consideration.) These would be concerns of the association. See the notes and highlighted portions below. The statute says this: 714. (a) Any covenant, restriction, or condition contained in any deed, contract, security instrument, or other instrument affecting the transfer or sale of, or any interest in, real property that effectively prohibits or restricts the installation or use of a solar energy system is void and unenforceable. SO, the associatians may-not prohiblit systems (above)-= but may provi€fereasonable !_imitations (see betovy), (b) This section does not apply to provisions that impose reasonable restrictions on solar energy systems. However, it is the policy of the state to promote and encourage the use of solar energy systems and to remove obstacles thereto. Accordingly, reasonable restrictions on a solar energy system are those restrictions that do not significantly increase the cost of the system or significantly decrease its efficiency or specified performance, or that allow for an alternative system of comparable cost, efficiency, and energy conservation benefits. (d) For the purposes of this section: (1) (A) For solar domestic water heating systems or solar swimming pool heating systems that comply with state and federal law, "significantly" means an amount exceeding 20 percent of the cost of the system or decreasing the efficiency of the solar energy system by an amount exceeding 20 percent, as originally specified and proposed. (B) For photovoltaic systems that comply with state and federal taw, "significantly" means an amount not to exceed two thousand dollars ($2,000) over the system cost as originally specified and proposed, or a decrease in system efficiency of an amount exceeding 20 percent as originally specified and proposed. (2) "Solar energy system" has the same meaning as defined in paragraphs (1) and (2) of subdivision (a) of Section 801.5. Note that the statute allows for HOA application and approval processes. This is important too. Hopefully, the HOA board is evolved enough to have a reasonable policy on solar installations (I have written many so know some HOAs are aware of this statute). Read on: (e) Whenever approval is required for the installation or use of a solar energy system, the application for approval shalt be processed http://www.communityassociations.net/cacondoguru/archives/2007/07/solar_energy_wh.html l l/1/2007 California Condo &HOA Law: Solar Energy - What Are The Trade-Offs?

In an effort to narrow our research and produce a product that could be used by a local government agency, we contacted the Truckee Donner Public Utility District (TDPUD) and discovered a need for information about solar energy systems in residential structures. Solar power is our indicator and our goal is to provide TDPUD with information regarding solar power products that can be used in new and existing residential structures. Senate Bill 1 (SB 1) — The Solar Initiative — requires that local publicly owned electric utilities have a public process to collect public funds which will be used to promote solar energy (photovoltaic - PV) systems. Rate payers will be able to receive rebates and be connected to the utility grid. SB1 has a number of regulatory requirements including establishing allowed equipment, installation methods and system configurations. Although PV systems are very expensive (up to $42,000 net after rebates for a 6,000 installed watt system), the future costs of electricity are unknown, as is the availability of rebates in the future. PV systems are feasible only if a rate payer's property receives adequate sun exposure. For this reason, properties with PV systems may increase the value of real estate in the future, thus helping to make PV systems more economically feasible. Cost and return on investment are important considerations when deciding to make an investment. One of the goals of SB1 is to make rebates available for PV systems; minimum rebates are $2.80 per installed watt, at this time a maximum Federal tax credit of $2,000 is also available (See form and instructions at http://www.irs.gov/pub/irs-pdf/f5695.pdf for IRS form 5695). To begin understanding the cost of a PV system, rate payers can locate "calculators" on the web. For instance, one example of a PV system calculator can be found at "Go Solar", which gives the rate payer an idea of price, savings and system size; http://www.findsolar.com/index.php?page=rightforme; the calculator also gives the solar system capacity required, the roof area needed, installation cost, increase in property value and estimated Return on Investment (ROI). Most PV system designers and installers can also give you estimates of rebates and system output when they are designing your system. Additionally, these professionals will know the technical requirements and will be able to determine the optimum energy results you will experience. SB1 rebates make the purchase of a PV system much more affordable, saving 28% of the total cost (Federal tax credits are not included in this analysis). Rebate savings significantly decreases monthly payments and interest, but even with SB1's rebate current electricity savings would not pay for the installation of a PV system in the short term. Additional considerations, including higher interest rates, longer financing terms and increased property values were not included in this analysis. 1.0 INTRODUCTION 1.1 Team Goal in Project The project team was united with a common goal of environmental awareness and the need for use of renewable energy sources in our area. Upon our initial efforts to establish a "measurable indicator", we were overwhelmed with the amount of information available and vast nature of the term "renewable energy". In an effort to narrow our research and produce a product that could be used by a local government agency, we contacted the Truckee Donner Public Utility District (TDPUD) and discovered a need for information about solar energy systems in residential structures. Our TDPUD contacts, Steve Hallebaugh and Alan Harry, directed our attention to Senate Bill 1 (SB 1, the California Solar Initiative) and the need for information regarding solar products. Solar power is our indicator and our team's goal, "Go Solar Get Rebate", is to provide TDPUD with information regarding solar power products that can be used in new and existing residential structures. 1.2 Senate Bill 1 Senate Bill 1 (SB 1), also know as the California Solar Initiative, was signed into law on August 21, 2006. This initiative was put into place to encourage residential and business rate payers to install solar energy systems (aka photovoltaic (PV) systems) through rebates and opportunities to offset part or all of the consumer's own electricity demand. SB1 requires each local publicly owned electric utility (LPOEU), "on or before January 1, 2008, to adopt, implement, and finance a solar initiative program" for the purpose of "investing in, and encouraging the increased installation of, residential and commercial solar energy systems." In addition SB1 imposes a state-mandated local program and requires that each LPOEU make certain program information available to its customers. In this way interested members of the public (typically the rate payers) along with the LPOEU will establish "eligibility criteria for solar energy systems receiving ratepayer funded incentives." SB1 establishes eight (8) requirements for the system incentives which include: 1. Design, installation, and electrical output standards 2. Purpose of the incentives (to offset part or all of the consumer's own electricity demand), 3. That the components of each system must be new—not previously used 4. The warranty of the system must be at least 10 years 5. The PV system must be located at the residence or business getting the incentives 6. The PV system must be connected to the LPOEU in the State of California (i.e., a "grid- tied" system) 7. The PV system must have meters which monitor and measure performance of the system, and the quantity of electricity generated 8. The PV system must be installed according to applicable specifications and codes Since the rebates will be funded by the rate payers, the California Energy Commission established conditions on the incentives developed by the LPOEU, which include installation and optimal solar energy system performance guidelines as well as the requirement of appropriate improvements in energy efficiencies when a PV system is installed. Each LPOEU is tasked with making SB1's goal of installing 3,000 megawatts of PV solar energy in California within 10 years. SB1's monetary incentives are set at a minimum of $2.80 per installed watt; this incentive declines no less than 7% each year. Each LPOEU must determine its share of the State goal. The public proceeding's purpose is to support SB1's goal and to determine if additional incentives are necessary to reach this goal. The public process and the comprehensive solar energy program must be completed by January 1, 2008. Section 387.5 (e) of S131 establishes reporting requirements. To fulfill these reporting requirements the LPOEU cannot use funds earmarked for low-income ratepayers, cost-effective Go Solar Get Rebate,2007 North Lake Tahoe-Truckee Leadership Program 1 include eligible renewable sources (such as geothermal and small hydroelectric), coal, large hydroelectric and natural gas. Our team developed a questionnaire to learn more about Senate Bill 1 and how the TDPUD will incorporate the new law into current practices. A copy of the questionnaire and corresponding answers provided by the TDPUD is included in Appendix A of this report. 1.4 Photovoltaic Products and The Grid Photovoltaic (PV) products are systems that use the sun's energy to create electricity. PV products are solar power technology that uses solar cells to produce direct current electricity by the interaction between sunlight and the semiconductor materials in a cell. A residential PV power system enables a homeowner to generate some or all of their daily electrical energy demand. A typical residential solar system consists of four components: Solar Modules, an Inverter, a Monitor and the Electric Meter. Solar Modules collect the sun's energy and convert it into electricity. Based on the electricity requirements, the appropriate number of modules are connected to form a rooftop or other mounted array. The Inverter converts the electricity from direct current (DC) to alternating current (AC) for use in the home. The Monitor allows the homeowner to view the status and performance of their system and the Electric Meter displays net power usage. Installation Options There are several ways to install a PV array at a residence. Consideration should also be given for access to the system. This access space can add up to 20% of needed area to the mounting area required. AV Mounted Systems The mounted systems are designed for maximum strength and ease of installation, Mounting racks are designed by � the area of the module(s) to be mounted, not necessarily by the number of module(s). Since most racks are module specific and not universal, then the number of parts can be reduced, simplifying the installation and assembly. However, it is crucial that the mounting rack is designed to accommodate the PV system you are considering installing. Most mounted systems are constructed of heavy gauge steel with fully welded caps. Hardened bolts are used to lock the mounting sleeve to the pole. Additional information regarding mounted systems can be found at www.power-fab.com . Mounted systems can either be mounted on the roof or on the ground. Ground mounted systems can be further broken down into either top-of-pole mounted or side-of-pole mounted. Roof Mounted Often the most convenient and appropriate place to put the PV array is on the roof of the building. The PV array may be mounted above and parallel to the roof surface with a standoff of several inches for cooling purposes. These systems have the advantage that the roof hardly needs to be disturbed to install them, making them the best choice for installations for some existing properties. However, proper roof mounting can be labor intensive, and particular attention must be paid to the roof structure and the weather sealing of roof penetrations. Most roof mounted installation systems offer fixing units and fixing anchors for various module construction types and for various types of roof coverings. Go Solar Get Rebate, 2007 North Lake Tahoe-Truckee Leadership Program 3 expanded in the future. Grid-tied solar systems are popping up all over California as homeowner's and businesses are realizing the incentives to go solar. 1.5 Why Go Solar? Why go solar? Every day, massive amounts of energy from the Sun blanket our planet. At the Earth's orbit, neglecting absorption by the atmosphere, each square meter of area facing the Sun receives about 1380 joules per second (nearly 2 horsepower); this quantity is known as the solar constant. Solar energy can play a key role in creating a clean, renewable, reliable energy future for our community, region, state, country, and planet. Here are a few of the many reasons to consider harnessing this solar energy for use in your home: 1. A PV system reduces, or can completely eliminate, the amount of electricity you have to purchase from your utility or electric service provider. 2. A PV system can save you money on your electric bill and act as a hedge against future price increases. 3. PV power can be a reliable energy source in a time when energy brownouts and blackouts are becoming more prevalent. 4. You help your community by reducing the electricity demand and provide additional electricity for the grid when you generate more than you use during the day, when this demand is highest. 5. Using solar energy produces immediate environmental benefits. Electricity is often produced by burning fossil fuels such as oil, coal, and natural gas. The combustion of these fuels releases a variety of pollutants into the atmosphere, such as carbon dioxide (COA sulfur dioxide (SOA and nitrogen oxide (NOX), which create acid rain and smog. Carbon dioxide from burning fossil fuels is a significant component of greenhouse gas emissions. These emissions could significantly alter the world's environment and lead to the global warming predicted by most atmospheric scientists. The combustion of fossil fuels releases more than 6 billion tons of carbon into the atmosphere each year. The United States alone is responsible for 23 percent of these emissions. Clean energy sources, such as solar energy, can help meet rising energy demands while reducing pollution and preventing damage to the environment and public health at the same time. Solar energy is an excellent alternative to fossil fuels for many reasons: • It is clean energy. Even when the emissions related to solar cell manufacturing are counted, photovoltaic generation produces less than 15 percent of the carbon dioxide from a conventional coal-fired power plant. Using solar energy to replace the use of traditional fossil fuel energy sources can prevent the release of pollutants into the atmosphere. ■ Using solar energy to supply a million homes with energy would reduce CO2 emissions by 4.3 million tons per year, the equivalent of removing 850,000 cars from the road. ■ Solar energy uses fewer natural resources than conventional energy sources. Using energy from sunlight can replace the use of stored energy in natural resources such as petroleum, natural gas, and coal. Energy industry researchers estimate that the amount of land required for photovoltaic(PV) cells to produce enough electricity to meet all U.S. power needs is less than 60,000 square kilometers, or roughly 20 percent of the area of Arizona. ■ Solar energy is a renewable resource. Some scientists and industry experts estimate that renewable energy sources, such as solar, can supply up to half of the world's energy demand in the next 50 years, even as energy needs continue to grow. Go Solar Get Rebate,2007 North Lake Tahoe-Truckee Leadership Program 5 Snow Load Criteria A snow load is a measurement of the weight of the heaviest snow load likely to occur in a two month period in a certain region. Most roof systems are designed to carry a dead load of 20 pounds per square foot. In localized areas of some snow-belt regions, snow loads of 150 pounds per square foot are not uncommon. Ground snow loads in the Tahoe Basin range from 223 psf to 403 psf depending on the elevation. Typical snow loads in the Town of Truckee are located in the Appendix, as an excerpt from the Town of Truckee "Permit Handbook for Single Family Residential Construction". More detailed information regarding snow load criteria from the Town of Truckee is included in Appendix B of this report. Snow loads in the Town of Truckee are based on two factors; the elevation a structure is located at, and the roof pitch of the structure. Roof snow loads may be considerably lower depending on roof pitch and exposure. Roof pitch is the slope of the roof surface generally expressed in inches of vertical "rise" per 12 inches of horizontal distance "run". (example: written as 4/12 or said as " 4 inch rise per 12 inch run " or simply"four twelve or four in twelve"). In the figure at left, the roof rises 4"for every 12" of horizontal run, hence a 4/12 pitch, aka "four twelve" or"four in twelve". r of also In the second figure, a roof with a 12/12 pitch is shown. Source: Town of Truckee, "Permit Handbook for Single Family Residential Construction, Appendix A— Municipal Code Chapter 15" http://www.townoftruckee.com/hand book.html. 2.3 California Energy Commission PTC Rating System The California Energy Commission (CEC) provides a rebate to customers that install PV systems. The rebate is predicted upon final AC watts, since these AC watts ultimately determine how much useable electricity comes out of the system. In order to determine what a solar module is capable of in the real world, the CEC conducts studies on the many different modules using criteria for dust, wiring losses, module mismatch, weather, and other related factors. The results of the studies are published on their website, http://www.consumerenerclycenter.org, The terminology used by the CEC can be confusing, but is better understood by the following definitions: • STC DC Watts — The nameplate rating of a solar module; Standard Test Conditions (STC). • PTC DC Watts —The rating of the module in real world conditions as determined by the CEC; Performance Test Conditions (PTC). • CEC AC Watts—The total PTC DC of solar modules factoring in inverter efficiency. This is the number that the rebate is based on. Go Solar Get Rebate,2007 North Lake Tahoe-Truckee Leadership Program 7 A solar contractor (C-46 designation) installs, modifies, maintains, and repairs active solar energy systems. An active solar energy system consists of components which are thermally isolated from the living space for collection of solar energy and transfer of thermal energy to provide electricity and/or heating and cooling of air or water. Active solar energy systems include, but are not limited to, forced air systems, forced circulation water systems, thermosiphon systems, integral collector/storage systems, radiant systems, evaporative cooling systems with collectors, regenerative rockbed cooling systems, photovoltaic cells, and solar assisted absorption cooling systems. A licensee classified in this section shall not undertake or perform building or construction trades, crafts or skills, except when required to install an active solar energy system. Senate Bill 1 (SB 1) requires that solar systems be installed by C-46 contractors to qualify for a rebate program. 2.5 National Voluntary Certification for Installers The North American Board of Certified Energy Practitioners (NABCEP) solar thermal installer certification is a voluntary certification that provides a set of national standards by which solar thermal installers with skills and experience can distinguish themselves from their competition. Certification provides a measure of protection to the public by giving them a credential for judging the competency of practitioners. It is not intended to prevent qualified individuals from installing solar thermal systems nor to replace state licensure requirements. The target candidate for NABCEP certification is the person responsible for the system installation (e.g., contractor, foreman, supervisor, orjourneyman). The NABCEP Solar Thermal Installer Certification has been developed in accordance with the certification field's best practices. NABCEP is a member of the National Organization for Competency Assurance (NOCA) and has endeavored to follow the requirements of ISO/IEC Standard 17024: General Requirements for Bodies Operating Certification Systems of Persons. To be eligible for NABCEP solar PV installer certification, candidates must first meet these basic requirements: 1. Be at least 18 years of age 2. Meet prerequisites of related experience and/or education 3. Complete an application form documenting requirements 4. Sign a code of ethics 5. Pay applicable fees 6. Pass a written exam Among other primary goals, the NABCEP is dedicated to the implementation of appropriate professional standards designed to protect consumers and the profession. NABCEP certificants and candidates are expected to act in an appropriate manner, which promotes the integrity of, and reflects positively on, the practitioner, the NABCEP, and the renewable energy profession, consistent with accepted moral, ethical, and legal standards. NABCEP is a member of the National Organization for Competency Assurance (NOCA) and has endeavored to follow the requirements of ISO/IEC Standard 17024: General Requirements for Bodies Operating Certification System of Persons. 2.6 Warranties Senate Bill 1 (SB 1) requires a minimum 10-year full-system warranty against defective parts, workmanship, or unusual degradation of output (performance)to qualify for a rebate program. Most of the products we researched come with a 20 to 25 year warranty for panels for an 80 percent operation. What this means is that after the 20 to 25 year life of a panel, the panel will not be completely dysfunctional, but will operate at 80 percent capacity.

Additional considerations including higher interest rates, longer financing terms and increased property values are not included in the above analysis. It is difficult to know how much electricity will increase in the future. Electricity rates have increased 6.7% per year for 30 years according to CPUC "Electric Rate Compendium", November 2001. According to Alan Harry "TDPUD annual rates have increased 1.96% per kilowatt hour over the last 20 years." Although past experience is not an indicator of future costs, this increase is considerably less than CPUC's increases. Additional rate increases may be tied to demand and lack of resources.

In order to achieve this goal the project group conducted research on affecting legislation in order to ensure chosen products for research met general specifications and would be usable in local projects. The group then identified the availability of various types of PV products locally and the availability of local, licensed installers. During the research process the group encountered several barriers and limitations some of which are disclosed below. The conclusions presented in this paper are not intended to be all inclusive. 5.1 Limited Time Frame This research project was conducted as a graduation requirement for the North Lake Tahoe — Truckee Leadership Program between February and May 2006, and, therefore, was compiled in a limited amount of time. The group found an extensive amount of information available and in order to draw all inclusive results additional time and expertise from professionals within the field would be needed. The cost analysis did not consider many financial considerations such as the time value of money, various interest rates and amortization schedules, changes in property values, and increased energy rates. In addition, we did not consider ecological costs such as the value of a PV system to decrease reliability on non-renewable resources, pollution and recycle costs.

Go Solar Get Rebate,2007 North Lake Tahoe-Truckee Leadership Program 23 APPENDIX A - TDPUD QUESTIONNAIRE Answer:Average cost of a solar photovoltaic system in California is$9 to$10 per installed watt, so a 1000 watt(rated)system would cost$9,000 to$10,000.A typical home size system is 2 to 3 kilowatts. e. Any other factors that need to be considered? Answers:Other factors that you need to consider: • Amount of TDPUD's solar incentive under its new SB1 program-estimated to start at $2.80 per watt(would be$2,800 for a 1000 watt system,$5,600 for a 2000 watt system,etc). • Federal Tax Credits available-$2000 for a residential PV system;30%of cost of a business PV system. • The tilt and orientation of the solar photovoltaic array will impact how much energy it produces, and may also affect your incentive from TDPUD. It's best to face the array south,at a tilt of between 10 and 40 degrees. • Any shading (from trees, nearby buildings,other roofs,chimneys)can seriously affect how much energy a PV system produces in a year. It may also affect the size of your TDPUD solar incentive! So avoid shading. 2. What is TDPUD's philosophy regarding alternative energy? Answer: TDPUD strives for low rates and excellent service for our customers.At the same time,we are located in a beautiful setting, and benefit from clean air and a clean environment.Solar energy is abundant in our territory, and is among the cleanest of power resources.We hope to encourage its use through our new program and introduce the benefits of solar to our customers.We also see local solar installations as a way of further developing employment opportunities for our customers. Finally,we recently have committed to a Renewable Portfolio Standard,and we see the Solar program as another vehicle to help us achieve renewable energy goals. 3. Is SB1 seen as beneficial or bureaucratic requirements that will not be beneficial to costs to rate payers or reduce drain on system? Answer: TDPUD is working hard to make the SB1 program easy to participate in, and at as low cost as possible to TDPUD ratepayers. The state legislation was designed so that consumer- owned utilities such as TDPUD would have the flexibility to implement programs in different ways. By simplifying the"bureaucracy",we can make the program available at tower cost to ratepayers and accomplish our fair share toward the statewide goals for solar. 4. What do you believe/know as the reason SB1 came to fruition? Answer S131 came about as a response of Californians to the challenges of continuing to import power at increasing cost,and at increasing damage to the environment.At the same time there is abundant clean solar power available to us all.TDPUD is in an excellent area to harvest large amounts of solar power in our own area and from our own rooftops. SB1 will help us do that. 5. Is TDPUD hoping to satisfy the requirements of SB1 by being all inclusive of rate payers or having a few large businesses install photovoltaic systems? Answer:We want to provide solar benefits to as many of our customers as are interested in participating. While we don't anticipate large businesses to install systems and exhaust the program funds,we will review the program from time to time to see if our intent of involving as many customers as possible is being met. 6. How will TDPUD ensure that the systems getting SB1 funding are in compliance with system requirements?Will you do inspections? Go Solar Get Rebate, 2007 North Lake Tahoe-Truckee Leadership Program Appendix A APPENDIX B- TOWN OF TRUCKEE SNOW LOAD CRITERIA b. Drifting due to adjacent obstructions. c. Accumulations in valleys and adjacent to parapet walls and chimneys. d. Ice loads on cornices. e. Possible impact loadings from snow falling on structure from higher roofs. f. Effect on structure from dynamic loading caused by snow sliding off roof. g. Snow sliding off roof and dynamically loading sidewalls by being forced against same due to snow embankment adjacent to the structure. h. Protection of entrances, exits and windows from the danger of falling icicles and snow sliding off pitched roofs. i. Ice weight where it will refreeze on unheated overhangs after having melted and run off from portions of roofs with heat below same. j. Projections through the roof, such as ventilation and plumbing vents, which may be torn off or damaged by sliding snow. 7. The following tabulated values may be used with roofs having pitch as shown. NOTE: These reductions do not apply to A-Frame or similar structures where the eave line extends below the anticipated snow depth. Roof Slope Percent of Tabulated Snow Load 7 in 12 80% x Snow Load 8 in 12 76% x Snow Load 9 in 12 72% x Snow Load 10 in 12 68% x Snow Load 11 in 12 64% x Snow Load 12 in 12 60% x Snow Load These roof loadings are applicable only to roofs having an eave height above the anticipated general depth to snow on the ground. In the case of"A-Frame" buildings and other similar types wherein the roof extends below the depth of the snow on the ground, a minimum of 1.4 times the tabulated values must be used on the roof below the ground snow level. Ground snow depth may be calculated by dividing the tabulated snow load by 25 Ibs/cubic foot. e.g., if tabulated snow load were 180 Ibs./sq. ft., the anticipated ground snow depth would be 7.2'. (180 divided by 25 = 7.2'.) Also, special design consideration must be made for the stress condition wherein the snow from the upper portion of the roof slides down on top of the ground snow and consequently further increases the loading on the lower portion of said roof. 8. Gables, hipped, or curved roofs shall be designed to resist stresses caused by unit live loading 1.2 times the values in Tables 23 B-1 and B-2 on one-half of the roof is such loading result in large members or connections.

Go Solar Get Rebate,2007 North Lake Tahoe-Truckee Leadership Program Appendix B Answer:TDPUD's program is designed to assure that all systems meet the quality and performance eligibility requirements required in SB1.There will be post-installation inspections to assure that systems meet these standards and that TDPUD ratepayers are getting the highest value for all funds invested in the Program, Systems must meet all Codes and Standards,must be properly oriented,and be minimally shaded or un-shaded to comply with requirements for systems under SB1. 7. Will net metering be available,will it be beneficial to TDPUD, how is SB1 net metering different than net metering now offered? Answer: Net metering will be available and we don't anticipate any changes to our existing net metering program. SB1 does not require any changes that we are aware of. 8. What is TDPUD's share of the 3,000 megawatt requirement for SB1? Answer: Of the 3000 MW statewide goat,TDPUD's share is 1.54 MW over the ten year life of the required programs found in SB- 1.We are 0.22%of the municipal utility load of 700 MW for that period.This would be the equivalent of over 500 typical residential sized (3 kW)systems. 9. What public involvement is anticipated/what is TDPUD's public involvement goal? Answer SB - 1 requires that the District's Board of Directors hold a public hearing to both discuss the proposed solar program and to receive public comment. We anticipate that this hearing will be held in June or July of this year. 10. You mentioned that you are going to be using a consultant to implement SB1's requirements,what is that company's name? Answer:We are scheduled to discuss the possibility of hiring Efficiency Services Group(ESG)to assist us in the preparation and implementation of the District's SB-1 program ESG currently has over 30 years of experience in solar energy and energy program design. Go Solar Get Rebate, 2007 North Lake Tahoe-Truckee Leadership Program Appendix A TDPUD Questionnaire: Definition of terms: 1. Kilowatt hours-1 know that a kilowatt is 1,000 watts, and is the number of kilowatts used in an hour, but what are the average kilowatts produced by a PV system? Answer: Photovoltaic systems come in all sizes from small to large.A 1000 watt(1 kilowatt)DC- rated system in our area would produce 1000 watts of power in full sunlight. In one hour, under the same sunny condition, it would produce 1000 watthours(1 kilowatthour)of energy.A 20,000 watt (20 kilowatt)photovoltaic system will produce 20 times the energy of a 1000 watt system. Note that power is measured in watts and is different than energy,which is measured in watthours, so be careful not to confuse the two. 2. Installed watt-how is this different than "Y below? Answer: An "installed watt" is term defining the capacity (power) of the photovoltaic system at its rated output in full sunlight. This is different from "Y below, which talks about energy in watthours or in thousands of watthours called kilowatthours that the PV system produces. In the TDPUD service area, a 1000"installed watt"PV system will produce about 1520 kilowatthours of energy per year,assuming it's facing south and tilted at an ideal 30 degree angle. So a 20,000"installed watt"system would produce 30,400 kilowatthours of energy per year here. 3. Electricity produced by the system measured in kilowatt hours? Answer:Yes,this is correct. The energy produced by a PV system is measured in kilowatthours. 4. What is net metering? Answer: Net metering is the utility rule by which you can connect to the utility and offset the energy(kilowatthours)you use in your home or building with kilowatthours produced by your photovoltaic system, all at the full utility retail rate. In other words,you are compensated full retail value for what you produce in your own home's photovoltaic system.This rule is a real benefit to you. General Questions: 1. We want to give the rate payers a simple calculation for break-even on a solar application. In order to do this I believe we need the following information: a. Average annual electric usage? Answer: 761 kwh/mo b. Average annual rate per kilowatt hour? Answer: For residential customers whose primary residence is Truckee,our rate is $.12 per kilowatthour. For our small commercial customers, is$.144 per kilowatthour. c. It would be helpful to have some discussion about the seasonal variances in electric demand. Answer: Our average customer monthly energy use is 700kwh/mo in the summer and 820kwh/mo in the winter. d. I believe I can get an average PV system cost, but your opinion/data would be helpful.

SB 1 requires that there be a minimum of one public hearing; however we suggest that the TDPUD have multiple public information workshops and meetings regarding SB 1. We suggest that public notices regarding the impacts of SB 1 be included in billing inserts, website postings, newspapers ads, and in the community calendar of the Sierra Sun. As a public agency, TDPUD must follow the minimum requirements for noticing public meetings, including Board and Committee meetings, such as the Electricity Advisory Committee. When the TDPUD sends information to their rate payers about SB 1 and its impacts, we recommend that the following items be communicated, per "The Six Stages of Communication During Change", as prepared by the California State University, Sacramento, Center for Collaborative Policy. 1. Discuss what the change actually is and when the change will be instituted. 2. Tell the constituents how the change will affect them —personally. Important information to convey should be what financial impacts SB 1 will have on each property owner in the TDPUD service area, including those who may not be able to install a PV system for various reasons. 3. Tell the constituents how to be part of the change/process. Inform them of the public information workshops and meetings. 4. Describe to the constituents why the change is a good idea and/or required. 5. Ask your constituents who else they think should be involved in the change. 6. Ask your constituents for ideas and suggestions to improve the idea (implementation of SB 1). The TDPUD has already done a lot of research and leg work to promote alternative energy sources in their service area; property owners considering a PV system should research their website www.tdpud.org and contact the TDPUD directly for additional questions. Additionally, the TDPUD has already created a "Photovoltaic Interconnection Agreement for Net Energy Metering from Residential Solar-Electric Generating Facilities of 10 Kilowatts or Less" located on their website at http://www.tdpud.orq/pdf/photovoltaic°/�20interconnection,Appdx.A.pdf. Go Solar Get Rebate,2007 North Lake Tahoe-Truckee Leadership Program 20 5.2 Lack of Expertise The research group was formed from like minded individuals interested in researching sustainable methods of generating electricity in the Tahoe-Truckee area. This research was not conducted by experts in energy related fields; therefore, the members of the research team had to educate themselves, in a limited amount of time, on general concepts relating to PV systems and electricity generation in order to make fair assessments when conducting research on products and installers for presentation in this project. 5.3 Geographical Location Although the research identified several products and installers available to homeowners in the Tahoe-Truckee area the availability is limited. The group concentrated on products and installers available within a 100 mile radius who would be sensitive to local climate limitations and local terrain. 6.0 CONCLUSIONS AND SUGGESTIONS The following are general conclusions and suggestions for property owners and the Truckee Donner Public Utility District, based on the limited research performed for the preparation of this paper. It is difficult to know how much electricity rates will increase in the future. Electricity rates have increased 6.7% per year for 30 years according to CPUC "Electric Rate Compendium" November 2001. According to Alan Harry "TDPUD annual rates have increased 1.96% per kilowatt hour over the last 20 years." Although past experience is not an indicator of future costs this increase is considerably less than CPUC's increases. Additional rate increases may be tied to demand and lack of resources. If rates increased substantially installation of a PV system with present dollar values would have a better return on investment due to higher annual electric savings. An additional consideration not included in this analysis is the increased market value of a house with an efficiently operating PV system compared to a home with out a PV system. Some of the purchase and installation cost may be recovered when the house is sold. For a more detailed financial analysis see "Payback and other Financial Tests for Solar on Your Home" by Andy Black; http://www.findsolar.com/pdfs/solar_payback.pdf . 6.1 Property Owners We suggest that property owners work with a licensed professional to design and install the PV system that is most appropriate for their residence or business. Additionally, property owners should meet with TDPUD officials if they have specific questions about the ramifications of SB 1 for their property, and how to receive a rebate. Property owners should also consider discussing the proposed PV system with a tax consultant, so as to receive the maximum tax credit(s) available. Below are some suggestions regarding design and installation of PV systems, as well as suggestions regarding the selection of a PV system designer and installer/contractor. Good Questions to Ask Solar Consultants 1. How long has the company been in business? 2. What organizations does the company belong to? 3. Do they hold a valid contractor's license? 4. Who is the manufacturer of the solar panel and inverter? 5. Does my equipment have a warranty?

Reference from http://www.gosolarcalifornia.ca.gov/information/calculator.html 3.0 PRODUCTS RESEARCHED The products we researched are used by local installers discussed in Section 4.0 of this report. More detailed product information is included in Appendix D of this report. The following are brief descriptions of the products researched during this study along with corresponding contact information. The North Lake Tahoe-Truckee Leadership Program 2007 is neither affiliated with nor endorsed by the following products companies discussed in this section. 3.1 Open Energy This product is PV glass roofing tiles that can handle up to 240lbs of snow load. These tiles can be installed in new homes or integrated with a flat tile roof. These tiles are strong enough to be walked on. To install you will need to work with a roofer or a solar power installer. A roofer can purchase the roofing tiles wholesale from Eagle Roofing and a solar power installer can purchase the roofing tiles wholesale from DC Power. These PV roofing tiles utilize high efficiency monocrystalline cells and are designed to blend seamlessly with commonly used cement tiles and can be flashed to integrate with other types of roofing materials. These tiles are available in black, red, brown, blue and grey. The wholesale cost for roofing tiles is around $200.00 for a three square foot section. The cost may vary depending on your setup. The cost for PV the installed can range from $8 to $12 per watt. The output from these tiles ranges from 1000 watts to 1150 watts per 100 square foot section. An average house needs a 6000 watt system which means you will need 600 square feet of roofing tiles. The wholesale cost for a 6000 watt system is $40,000.00. The installed cost for a 6000 watt system is $48,000.00 to $72,000.00. Open Energy offers a 25-Year warranty on 80% power output. Go Solar Get Rebate, 2007 North Lake Tahoe-Truckee Leadership Program 12 Most inverters, monitors and electric meters come with a 5 to 10 year warranty, so replacement of these components will be more frequent than the panels, which comprise most of the cost of the systems. 2.7 Cost Analysis The "Go Solar" website has a number of calculators, one of them called CECPV Calculator Version 2, which assist a potential PV user to determine the time dependent valuation (TDV) production and the amount of California Energy Commission (CEC) incentive. The calculator uses a model, developed at the University of Wisconsin, which takes into account the type of system, the location of the PV system (City in California), the roof slope, and distance the solar panels are from the roof. A lay person that doesn't know any of this information can run a test simulation. Known data can be entered and the calculator will choose the type of equipment and other technical criteria. The calculator is easily downloaded from the "Go Solar" website at http://www.gosolarcalifornia.ca.gov/information/calculator.html. Another calculator found at "Go Solar' is Find Solar.com which gives you an idea of price, savings and system size; http://www.findsolar.com/index.php?page=rightforme This calculator does not have to be downloaded and is easy to use. You will need to input your electric use information; the calculator will tell you the solar system capacity required, the roof area needed, installation cost, increase in property value and estimated Return on Investment (ROI). Most PV system designers and installers can also give you estimates of rebates and system output when they are designing your system. Additionally, these professionals will know the technical requirements and will be able to determine the optimum energy results you will experience. Cost and return on investment are important considerations when deciding to make an investment. One of the goals of SB1 is to make rebates available for PV systems; minimum rebates are $2.80 per installed watt. Also, at this time a maximum Federal tax credit of $2,000 is also available (See form and instructions at http://www.irs.gov/pub/irs-pdf/f5695.pdf for IRS form 5695). According to Alan Harry with Truckee Donner Public Utility District (TDPUD), in 2007 the average home located in the TDPUD service area used 761 kilowatthours (kwh) per month, which costs $1,096 per year. If a household uses 9,132 kwh/year (761 kwh/month) it would need to install a PV system that is rated at 6,000 installed watts. The average cost of a PV system is $9.00 to $10.00 per installed watt. Homeowners need not install a PV system that would cover most of their electric energy requirement. According to Alan Harry a PV system which supplies 5% to 15% is beneficial. The matrix below shows the annual savings, total cost, payments and cost of capital for a PV system that supplies 100%, 50%, 40% and 25% of the average residential electrical requirement. In this scenario there is no rebate credit or Federal tax credit. Go Solar Get Rebate, 2007 North Lake Tahoe-Truckee Leadership Program 10 When a solar modules nameplate states 175 wafts, this means that in perfect conditions, the module will produce 175 watts of power. In controlled conditions, a manufacturer will measure how much power comes out of a module by using specialized instrumentation. This measurement is defined as the Standard Test Conditions (STC) and is the nameplate rating known as STC watts. When the CEC conducts a study on a module, they revise the STC watts based on performance, or better known as Performance Test Conditions (PTC). For example, a Sharp ND-205U1 module has a STC of 205 watts. Following a CEC study, the watt is revised to 180.6 PTC watts. All of the power generated from the solar modules is converted from Direct Current (DC) to Alternating Current (AC). This conversion is performed by the inverter, which has its own efficiency rating. Like solar modules, the CEC has efficiency ratings they use. A typical example of how the rating system works is shown in the following: A copy of the partial list of approved products and CEC ratings for these products are included in Appendix C of this report. Example, 18 Shell 175 watt modules and a PV Powered 2800-XV inverter. The 175 waft modules are rated at 158.3 watts (PTC). 18 modules multiplied by 158.3 equals 2,849 watts. The PV Powered 2800-XV inverter has an efficiency rating of 94.5 percent, thus the AC size of this system would be 2,692, or 2,849 multiplied by 0.945. The CEC will then determine the rebate amount on the current rebate level multiplied by the AC watts, as shown below: • Module Nameplate Watts (STC Watts) = 175 • Total STC Watts = 3150 • PTC Rating for each module = 158.3 • Total PTC = 2849 • Inverter Efficiency = 94.5% • CEC AC Watts = 2692 • Rebate Amount= $7,000 Source: "Unlimited Energy — Understanding STC, PTC, and CEC AC Watts" (http://unlimited — energy.com/content/view/l10/82). The CEC list of approved products contains over 100 items and associated ratings. For the purposes of this report, we included only those products that were researched during this study. A copy of the partial list of approved products and CEC ratings for each product are included in Appendix C of this report. 2.4 California Licensing Requirements for Installers The California Business and Professions Code (Division 3, Chapter 9. Contractors, Article 4) has three classifications for contractors that practice business in the state: General Engineering Contracting, General Building Contracting, and Specialty Contracting. A general engineering contractor is a contractor whose principal contracting business is in connection with fixed works requiring specialized engineering knowledge and skill and is in connection with any structure built, being built, or to be built, for the support, shelter, and enclosure of persons, animals, chattels, or movable property of any kind, requiring in its construction the use of at least two unrelated building trades or crafts, or to do or superintend the whole or any part thereof. A specialty contractor is a contractor whose operations as such are the performance of construction work requiring special skill and whose principal contracting business involves the use of specialized building trades or crafts. Solar contractors are considered a type of specialty contractor.

We researched local vendors and installers within a 100 mile radius of the Tahoe-Truckee area in an attempt to collect accurate information that is unique to our mountain climate and snow loads. We also used this criteria to help reduce costs associated with shipping and travel. 2.2 Wattage, Sunlight and Snow Load Criteria The following criteria were used to assist in researching the correct products that would be useful to our geographic area: Average Watts Used in Truckee According to Alan Harry of TDPUD, in 2006 the average home located in the TDPUD service area used 761 kilowatthours (kwh) per month. More detailed information regarding wattage of products is included in the following Section 3.0 of this report. Hours of Sunlight Shading of the solar electric system is potentially the most critical problem to avoid over the life of the system to ensure high performance. Shading can be caused by 1) obstructions that exist at the time of the installation of the system or 2) obstructions that occur through the maturation of trees or the subsequent construction of neighboring structures. To protect California's investment in solar systems and to ensure homeowners get what they paid for, it is critical to avoid both types of obstructions. The "minimal shading" criterion is designed to do this. The "minimal shading" criterion is that no obstruction is closer than a distance ("D") of twice the height ("H") it extends above the PV modules. Any obstruction that projects above any portion of the PV array must meet this criterion for the PV array to be considered minimally shaded. Obstructions that are subject to this criterion include any vent, chimney, architectural feature, mechanical equipment or other obstruction that projects above the roof of the residential building with the installed solar system, any part of the neighboring terrain that projects above the roof of the residential building, any tree that is mature at the time of installation of the solar system or any tree that is planted or planned to be planted as part of the landscaping for the residential building (the expected performance calculation must be based on the expected mature height of any tree planted or planned to be planted as part of the landscaping for the residential building), any existing or planned residential building or other structure neighboring the residential building with the solar system and any telephone or other utility pole that is closer than thirty feet from the nearest point of the array. See Appendix 4 of the NSHP Guidebook for more information about how to meet the "minimal shading" criterion and how to account for shading that fails to meet the "minimal shading" criterion in the expected performance calculation. Go Solar Get Rebate, 2007 North Lake Tahoe-Truckee Leadership Program 6 Ground Mounted Top-of-Pole mounted The PV array is mounted on the top of a pole buried in the ground, to a sufficient depth to provide structural stability. The height of the PV array must be designed to be above snow depths and/or vegetation. Side-of-Pole mounted The PV array is mounted via a bracket system, on the side of a pole buried in the ground, to a sufficient depth to provide structural stability. The height of the PV array must be designed to be above snow depths and/or vegetation. Building Integrated PV Array (BIPV) Systems Another type of installation for PV systems is a Building Integrated Photovoltaic (BIPV) system, which consists of integrating PV modules into the building envelope, such as the roof or the facade. BIPV systems can become an integral part of the building, often serving as the exterior weather skin or the roofing material. By simultaneously serving as building envelope material and a power generator, BIPV systems can provide savings in materials and electricity costs, reduce use of fossil fuels and emission of ozone depleting gases, and add architectural interest to the building. Commercially available products currently include roof tiles and standing seam metal roofing products. In BIPV applications different types of modules, depending on the application, can be used: classic (framed) modules, flexible crystalline or thin-film on metal substrate, roof-tiles with solar cells, and other modules. Reference: Whole Building Design Guide website, http://www.wbdq.org/design/bipv.php, and Greenpeace Energy website, http://www.pvresources.com/en/bipven.php. Roof Tile Systems Solar Roof Tiles are designed to blend with regular roof tiles. PV the installation is as easy as installing a standard roof tile. Designed to match the profile of concrete roofing tiles, PV Tiles blend into the roof in size, shape and color. These Solar electric tiles provide power by converting sunlight into DC (direct current) electricity. The DC power is then fed into an inverter to produce standard utility-grade electricity. This type of system should be installed by qualified personnel only. The system involves electricity, and can be dangerous if the personnel are not familiar with the product. Before installing the solar system, be sure to contact your local utility and building department to determine the necessary permit, installation and inspection requirements. Grid Tied Systems If excess power is produced during a month, a power credit is carried forward to be used during a month when more power is used than produced. With a net metering system, the system uses the power company like a battery, "storing" excess power with 100% efficiency, unlike ordinary batteries .; „ L that lose power during charging, storage, and discharge. In addition, the inverters used with these systems employ "maximum power point tracking (MPPT) technology", a new, more efficient mode of operation that allows the solar modules to operate at their "maximum power point," allowing far more of the power that is produced to be used or sold to the power company (up to 95%). Because of increased efficiency, net metering systems allow the solar array to deliver more power with less modules, substantially reducing system cost. Elimination of the battery bank also results in substantial savings, as well as reduced maintenance and replacement costs. These systems are modular and can be easily Go Solar Get Rebate,2007 North Lake Tahoe-Truckee Leadership Program 4 energy efficiency or other demand response programs. The requirements for each LPOEU includes reporting to its customers, the Legislature and to the State Energy Resources Conservation and Development Commission the following results for the past year: • The number of PV watts installed • Total number of PV systems installed • Total number of applicants • The amount of incentives awarded • Contribution toward program goals S131 established a maximum expenditure level for the state of $784,000,000; each LPOEU's maximum expenditure level is relative to its electricity load compared to the state load for all LPOEUs. A LPOEU's expenditures may be less if its funding adequately fulfills the required incentives. Net metering is described as an incentive to "encourage substantial private investment in renewable energy resources, stimulate in-state economic growth, reduce demand for electricity during peak consumption periods, help stabilize California's energy supply infrastructure, enhance the continued diversification of California's energy resource mix, and reduced interconnection and administrative costs for electricity suppliers." Net metering therefore must be made available to qualified customer-generators on a "first-come-first-served basis" and does not have to be given after customer-generators exceed 2.5% of the LPOEU's aggregate customer peak demand. SB1 states that net metering calculates the difference between the electricity supplied to the eligible customer-generator and the electricity generated by the eligible customer-generator which is fed back to the electric grid over a 12-month period. The rules for annualized net metering calculation can be found in SB1 at SEC 6. Section 2827 (h). The LPOEU must provide net electricity consumption information with every regular bill but does not need to pay for excess power generated on a monthly basis; the customer can pay for net energy consumed on a monthly basis. Every 12 months the LPOEU will calculate the net short- fall or excess energy generated. If excess energy has been generated by the eligible customer- generator, compensation will be made only if there is a purchase agreement with the LPOEU. This is not meant to be a complete disclosure of SB1 but instead is meant to highlight some of the requirements and guidelines.

They are a non-profit, publicly owned utility governed by officials elected by the registered voters of the District. All the benefits of public power remain in the District in the form of reliable electric service and high quality water at fair, reasonable prices. According to TDPUD, "The Mission of Truckee Donner Public Utility District is to provide adequate, reliable and high quality water and electrical power services, and to manage District resources in an open, responsible, environmentally sound manner at the lowest practical cost. In pursuing this Mission, the District will actively seek renewable energy sources as set forth in it Renewable Portfolio Standard". TDPUD purchases its energy through bilateral contracts with entities outside the Truckee area.

Introduction: California Solar Initiative Program The California Solar Initiative(CSI)Program Handbook for Truckee Donner PUD is to provide complete information to Truckee Donner PUD to implement a solar incentive program fully compliant with California legislation SB-1. This Handbook consists of two parts: Part A: Program Background and Program Design Part B: Program Procedures and Processes Part A will cover the governing State Law, will provide information on SB-1 as it relates to Publicly-owned utilities, including program goals and budgets.This Part will further discuss the options that each Publicly- owned utility has in the design of its local program. It will also discuss implementation features that will become part of the Program of the surrounding Investor-Owned Utilities and how this impacts the design of Public Utility programs.Finally,Part A will describe the Program designed for Truckee Donner PUD. Part B will cover the detailed procedures and processes for implementation of the Program by Truckee Donner PUD. Part A: Program Background and Design 1.0 Program Background In 2006, the California legislature passed SB-1, which is commonly called the California Solar Initiative. It mandates utilities put into place programs to assure that 3000 MW of solar installations on homes is in place within 10 years.The mandate for programs covers both Investor-Owned Utilities and Publicly-Owned Utilities.The section of the SB-1 law that covers Publicly-Owned Utilities is Section 5. (Attached to this Handbook as Appendix A). In summary,Publicly-owned utilities are to perform the following: 1. Each Publicly-Owned utility is to"adopt, implement, and finance"a solar initiative program, implemented by January 1, 2008 2.The utility is to offer an incentive of not less than$2.80 per watt for solar electric systems installed capacity, or for the electricity produced by the solar energy system, measured in kilowatthours. (Choice is left up to the utility) 3.The incentive level is then to decline each year at a rate of no less than an average of 7 percent per year. 4. The utility has to have a public proceeding to fund the program to adequately support their portion of the 3000 MW goal. 5.The solar electric systems need to meet certain eligibility requirements(See Section below) 6. The utility must make available information relating to the utility's solar program including the number of photovoltaic solar watts installed, the total number of photovoltaic systems installed,the total number of applicants,the amount of incentives awarded,and the contribution toward the program goals. requirements/qualifications/licensing.This minimizes and streamlines utility communications with solar contractors serving multiple utility areas. 4. The Program, inasmuch as is practical and cost-effective,enlists tools and techniques developed for and used by other CA utilities. 5.Builds on programs and processes already established and in use by Efficiency Services Group 6.The program is designed to be suitable for smaller utilities,easy to understand, and simple and cost- effective to administer while at the same time adhering to all appropriate laws and rules. 2.1 Truckee Donner PUD Program Beginning in 2008,the Truckee Donner PUD program will pay incentives to solar projects less than 5 kW through an up-front incentive,known as an estimated performance-based buydown (EPBB).EPBB is based on an estimate of the system's future performance.These estimated-performance incentives combine the benefits of rewarding performance of the PV system with the administrative simplicity of a one-time incentive paid at the time of project installation. The solar project's Site must be within the Truckee Donner PUD electric service territory. 2.2 Truckee Donner PUD Program Budget The Truckee Donner PUD's program budget as authorized by the TDPUD Board of Directors shall be$1.77 million total for the 10 year lifetime of the Program. 2.3 MW Targets and Step Triggers for CS/ Program Based on a proration of energy sales in recent years vis a vis all publicly-owned utilities in California, Truckee Donner PUD assumes a target of 1610 kilowatts of solar PV installed for the duration of the solar program. The incentive levels for the Truckee Donner PUD program will be automatically reduced over the duration of the program each year.Projects are counted toward the kW goal once they are deemed eligible and have received a confirmed reservation.The MW target for Truckee Donner PUD is 1.61 MW or 1610 kW for the 10-year duration of the program. 2.4 Incentive Structure The Truckee Donner PUD program will offer one type of incentive: an EPBB (Estimated Performance Based Buydown).The EPBB incentive is a one-time payment,based on verified characteristics such as system size, shading,and orientation.The incentive payment levels will automatically be reduced over the duration of the Truckee Donner PUD program in 10 steps.The EPBB level is directly tied to the steps as outlined in Table 1. 2.4.1 Expected Performance Based Buydown (EPBB) Incentives The Truckee Donner PUD EPBB pays a one-time up-front incentive ($/W)based on a system's estimated future performance.The Truckee Donner PUD will use the Energy Commission's CEC-AC method to The following are not eligible for incentives under the Truckee Donner PUD program: . Customers who have entered into utility contracts for distributed generation(DG)services (e.g.,DG installed as a distribution upgrade or replacement deferral)and who are receiving payment for those services.This does not include third-party ownership arrangements, i.e.,power purchase agreements, which are allowed. . Customers who have entered into agreements that entail the export and sale of electricity from the Host Customer Site.This does not include net energy metering agreements, which are allowed. . Any portion of customer load that is committed to electric utility interruptible,curtailable rate schedules, programs, or any other state agency-sponsored interruptible,curtailable,or demand-response programs.For electric utility customers who are on an interruptible rate,only the portion of their electric load that is designated as firm service is eligible for the Truckee Donner PUD program. Customers must agree to maintain the firm service level at or above capacity of the proposed solar system for the duration of the required applicable warranty period(see Section 2.3).Customers may submit a letter requesting an exemption to the firm service rule if they plan to terminate or reduce a portion of their interruptible load. Residential new construction systems are not eligible for the Truckee Donner PUD program and should apply to the California Energy Commission's New Solar Homes Partnership Program. 3.1.2 System Owner The System Owner is the owner of the generating equipment at the time the incentive is paid. For example, when a vendor sells a turnkey system to a Host Customer,the Host Customer is the System Owner. In the case of a third-party-owned system(or leased system, for example), the lessor is the System Owner. The System Owner should be designated on the Solar Photovoltaic Program Application Form, if known at that time, and on the Incentive Payment Claim Form. If different from the Host Customer, the System Owner shall also be a party to the Truckee Donner PUD program contract.The PUD may require documentation substantiating equipment ownership. 3.1.3 Applicant The Applicant is the entity that completes and submits the Truckee Donner PUD program application and serves as the main contact person for the Truckee Donner PUD throughout the application process.Host Customers may act as the Applicant or they may designate a third party to act as the Applicant on their behalf. Applicants may be third parties(e.g., a party other than TDPUD or the utility customer) such as,but not limited to,engineering firms, installation contractors,equipment distributors,energy service companies (ESCO)and equipment lessors. 3.1.4 Installer Alt systems must be installed by appropriately licensed California contractors in accordance with rules and regulations adopted by the State of California Contractors State Licensing Board(CSLB).Installation contractors must have an active A,B,or C-10 license,or a C-46 license for photovoltaic (PV)systems. 3.2.1 New Equipment, Not Pilot or Demonstration Systems All major system components must be new and must not have been previously placed in service in any other location or for any other application.Rebuilt,refurbished,or relocated equipment is not eligible to receive the Truckee Donner PUD program incentives. Components that are critical to the PV systems must have at least 1 year of documented commercial availability to be eligible. Commercially available means that the major solar system components are acquired through conventional procurement channels, installed and operational at a Site. Commercially available does not include field demonstrations for proof-of-concept operation of experimental or non- conventional systems partially or completely paid for by research and development funds. An alternative method of seeking eligibility for solar systems that use new technologies is to obtain certification from a nationally recognized testing laboratory indicating that the technology meets the safety and/or performance requirements of a nationally recognized standard. System component ratings must also be certified by the CEC as described in section 3.2.4. As an exception,the Applicant may specify equipment that has not yet received CEC certification,but the equipment must be certified prior to the first incentive payment. 3.2.2 Eligibility of Replacement PV Systems Any replacement solar systems must meet the criteria for new systems and are eligible for the Truckee Donner PUD program only if the removed system did not previously receive an incentive. 3.2.3 Equipment Must Serve On-Site Electrical Load To be eligible,the system must be sized so that the amount of electricity produced by the system primarily offsets part or all of the customer's electrical needs at the Site of installation.The expected production of electricity by the system may not exceed the actual energy consumed during the previous 12 months at the Site,as calculated per the following formula: Maximum System Capacity(kW)= 12-months previous energy usage (kWh)/(0.18 x 8760 hours/year) The Applicant must show evidence of the system sizing with the submittal of the initial application. The maximum incentive provided for a Host Customer Site under the Truckee Donner PUD program is 5 kW. 3.2.4 Equipment Certifications and Rating Criteria System components for systems installed under the Truckee Donner PUD program must be certified through the California Energy Commission's program that certifies major components of PV systems and provides lists of eligible equipment. The list of the currently certified equipment is available through: The California Energy Commission: www.energy.ca.gov California Energy Commission Call Center: (800) 555-7794. NOTE: The CEC-AC rating standards are based upon 1,000 Watt/m2 solar irradiance, 20 'Celsius ambient temperature,and 1 meter/second wind speed.The CEC-AC Watt rating is lower than the Standard Test Conditions(STC), a Watt rating used by manufacturers. 3.2.5.1 System Sizing Based on Future Load Growth In the case of Applicants with new or expanded facilities where no electric bill or where the existing electric bill does not reflect the Applicant's expected expanded consumption, the Applicant must include an engineering estimate.The engineering estimate must include the appropriate substantiation of the forecast of the Host Customer Site's annual energy use (in kWh)if the generating system size is based on future load growth, including new construction,load growth due to facility expansion or other load growth circumstances. Suggested methods of demonstrating load growth include Application for Service with corresponding equipment schedules and single line diagram;building simulation program reports such as eQUEST,EnergyPro,DOE-2, and VisualDOE; or detailed engineering calculations.The Truckee Donner PUD will verify the load growth predicted before moving forward with the Confirmed Reservation Notice. 3.3 Energy Efficiency Requirements (Utility Option) In order to qualify for the Truckee Donner PUD Solar incentive,the customer is required to participate in the following ways in TDPUD's energy efficiency programs: 1. The customer shall have had aii TDPUD energy efficiency audit. 2.The customer shall have installed all recommended measures with a less than 3 year payback. 3.4 Warranty Requirements In 2007, all systems must have a minimum 10-year warranty to protect the purchaser against system or component breakdown.The warranty must cover and provide for no-cost repair or replacement of the system or system components including any associated labor for 10 years.The warranty must also cover the major components of the solar system against breakdown or degradation in electrical output of more than 10 percent from their originally rated electrical output during the 10-year period.Major components are defined as PV modules and inverters. The warranty may be provided in combination by the manufacturer and installer. Self-installed systems (by other than a qualified and registered participating installer)do not qualify for the TDPUD incentive. 3.5 Performance and Permanency Requirements Equipment installed under the Truckee Donner PUD program is intended to be in place for the duration of its useful life. Only permanently installed systems are eligible for incentives.This means that the PV system must demonstrate to the satisfaction of the PUD adequate assurances of both physical and contractual permanence prior to receiving an incentive. All systems receiving a Truckee Donner PUD program incentive will require that the Host Customer and System Owner have the following minimum level of homeowner liability insurance or commercial general liability insurance for the term of the TDPUD program contract: $2,000,000 for each occurrence if the system rating is greater than 100 kW $1,000,000 for each occurrence if the system rating is greater than 20 kW and less than or equal to 100 kW $500,000 for each occurrence if the system size is 20 kW or less $200,000 for each occurrence if the system size is 10 kW or less and Host Customer is connected to an account receiving residential service from their electric utility. Additional insurance requirements and terms are included in the Truckee Donner PUD program contract. 3.6.2 Insurance Requirements for Installers Installation contractors must have valid workers compensation,business auto and commercial general liability insurance. Commercial general liability insurance must be in the following amounts: $1,000,000 for each occurrence and$2,000,000 aggregate. Workers compensation insurance or self-insurance indicating compliance with any applicable labor codes, laws or statutes, state or federal, where Installer performs work. . Auto coverage shall be at least as broad as the Insurance Services Office California Business Auto Coverage Form(CA 00 0103 06)covering Automobile Liability symbols 7, 8, and 9. Specifically described autos shall include any and all autos that will be used in connection with the project.The limit shall be not less than$1,000,000 each accident for bodily injury and property damage. 3.6.3 Insurance Requirements for Government The Truckee Donner PUD does recognize that some Government entities are self insured and/or have blanket coverage.The PUD will accept proof of that coverage as long as the Government entity can show that they meet the level of insurance required by the Truckee Donner PUD program. 3.6.4 General Insurance Requirements (Non-Residential Projects) Workers' Compensation: Workers' Compensation insurance or self-insurance indicating compliance with any applicable labor codes, laws or statutes, state or federal, at the Site where Host Customer or System Owner performs work. Business Auto: Auto coverage shall be at least as broad as the Insurance Services Office California Business Auto Coverage Form(CA 00 0103 06)covering Automobile Liability symbols 7, 8,and 9. Specifically described autos shall include any and all autos that will be used in connection with the project.The limit shall be not less than$1,000,000 each accident for bodily injury and property damage. System Owner fail to bring the system to full eligibility within the 60 days,the application will be cancelled and determined to be a failed inspection.The failure will constitute a strike against the installer. If there is a failed inspection for reasons that the verified system is not in compliance with the stated system, the Applicant,Host Customer, and System Owner will have 60 calendar days to bring the system into compliance as stated on the project application.However,this will automatically constitute a failure against the Installer or Applicant, depending on which entity signed and submitted the erroneous information on the project application and/or subsequent incentive claim form. Project Installers and Applicants who fail three random inspections will be excluded from Truckee Donner PUD program participation. If an Installer or Applicant fails two inspections,the Installer or Applicant will be on probation, wherein every project will be inspected. If the Installer or Applicant fails a third inspection,the Installer or Applicant will be disqualified from participating in the Truckee Donner PUD program. If an Installer or Applicant disputes the failed inspection or disqualification,he or she may appeal in writing within 30 days of notification of the failed inspection via US certified mail to TDPUD.TDPUD will review the appeal. Written appeals should substantiate any reasons he or she believes warrant reconsideration of the failure or disqualification.The final decision will be provided to the Applicant or Installer within 60 days of receipt of the written appeal and the appeal decision of the panel shall be final. 3.9.2 Inspector Training Criteria TDPUD will assure that all system inspection visits are by trained personnel, whether the inspection is performed by the Truckee Donner PUD inspectors, other utility personnel,or contractors.TDPUD may participate in a site inspectors training plan provided by the State of California. 4. Truckee Donner PUD Program Incentive Structure The Truckee Donner PUD program offers one type of incentive: EPBB,Expected Performance-Based Buydown. 4.1 Program Incentive Trigger Mechanism The incentive payment levels will automatically be reduced over the duration of the Truckee Donner PUD program in 10 annual steps. On average, the Truckee Donner PUD incentives are projected to decline at an average rate of 10-20 percent per year following implementation in 2007.The incentives will phase out over the 10 years. Table 1 outlines the 10 steps for the incentive levels for the Truckee Donner PUD Solar Program, designed to reach the minimum 1610 kW cumulative goal by 2016;Table 2 contains annual budgets to support the program. Table 1 Ye�ac Kilmvatts Residential Incentive Commercial Incentive Per Year $per kW per kW previous year due to events such as Applicants dropping out of the process,those kW will be added to the next year, increasing the number in that year and ensuring that no kW are left outstanding. 4.2 Expected Performance Based Buydown (EPBB) Incentives The Truckee Donner PUD program will pay incentives to solar projects with system ratings of less than 5 kW through an up-front incentive known as an EPBB.These EPBB incentives are based on an estimate of the system's future performance.EPBB incentives combine the benefits of rewarding performance with the administrative simplicity of a one-time incentive paid at the time of project installation. The PUD will use the Energy Commission's CEC-AC method to determine the system rating. In addition, the EPBB program will apply to all new construction other than building integrated systems (BIPV), regardless of size. The following formula determines the EPBB incentive: EPBB Incentive Payment=Incentive Rate x System Rating x Design Factor The design factor is a ratio comparing a proposed system to a baseline system as follows: Design Factor=Proposed System/Baseline System The design factor for EPBB will: Account for shading Assign optimal orientation tilt for each compass direction Include Truckee Donner PUD specific criteria to account for weather variation Use the Truckee Donner PUD's optimal reference latitude tilt that relates to the Truckee Donner PUD latitude. 4.2.1 Incentives for Residential Installations Residential installations will be provided a one-time payment under the EPBB program to help reduce the cost of installation provided the system size is less titan 4 kN<<.The amount of the EPBB incentive payment for the Truckee Donner PUD is as calculated pursuant to the formula in Section 3.2, with the incentive rate portion of the formula determined as shown by the following Table. Incentives for residential new construction projects will be funded through the Energy Commission's New Solar Homes Partnership program. 4.2.2 Incentives for Non-Residential Installations 4.4.3 Right to Audit Final Project Costs The Truckee Donner PUD reserves the right to conduct spot checks to verify that payments were made as identified in the final invoices or agreements provided by equipment sellers and/or installers.As part of these spot checks,the PUD will require Applicants to submit copies of cancelled checks,credit card statements, or equivalent documentation to substantiate payments made to the equipment seller and/or installer. When submitting this documentation, Applicants are encouraged to remove their personal account numbers or other sensitive information identified in the documentation. Applicants must explain the difference if the final amount paid by the Applicant is different from the amount of the purchase or installation shown in any agreement or invoice or in the previously submitted Solar Photovoltaic Program Application Form. If selected for a random audit, Applicants must submit final system cost documentation clearly identifying the final amount paid or legally incurred to purchase the system and the final amount paid to install the system.The cost documentation must provide proof of the final amount paid or legally incurred by the System Owner to the equipment seller and/or installer and provide sufficient information to clearly identify the equipment purchased and the labor paid.The final amount paid or legally incurred to the equipment seller and/or the final amount paid to the installer must match the cost information identified in the Reservation Confirmation and Incentive Payment Claim Form.To meet this requirement,the System Owner must submit final invoices and/or a copy of the final agreement.The actual amount paid or legally incurred by the purchaser to the equipment seller and/or the actual amount paid to the installer must be clearly indicated. If there is no direct proof of actual payment from the System Owner to an appropriately licensed installer,the incentive will be reduced. In addition,the final invoices or agreements should clearly indicate the extent to which the Truckee Donner PUD program incentive lowered the cost of the system to the System Owner. If the System Owner has entered into an agreement to pay the equipment seller over time rather than in lump sum, the final agreement must indicate the terms of payment and the amount of any deposits or payments paid by Applicant to the equipment seller to date.The System Owner must pay the cost of any system installation prior to submitting a payment request to the Program Administrator. 4.4.4 Site and Host Customer Limitations There are no restrictions on the amount of incentive funding a Host Customer can reserve and receive. Host Customers can reserve up to the maximum incentive funding from the Truckee Donner PUD program for a single Site for the duration of the Truckee Donner PUD program. 4.5 Truckee Donner PUD Program Database One of the notable features of the Truckee Donner PUD program is that it will participate in the State of California California Solar Initiative database.TDPUD will establish and maintain an up-to-date database that will collaborate with the Statewide database information on the progress of the CSI program. The information will include the following data from each project: .. Installer Part B: Program Procedures and Processes TDPUD will use an"informal"program process, outlined below. INFORMAL PROCESS 5. Application and Payment Processes for Truckee Donner PUD Projects The Truckee Donner PUD has selected a simplified informal process for Application and Payment for PV systems that qualify under the Truckee Donner PUD program.The PUD will provide information to assist the customer to file an Application.The customer and/or installer/contractor files the Application with the PUD.

Contact information is listed below. 7. Additional Information 7.1 Circumstances Requiring Additional Documentation 7.1.1 Owner or Self-Installed System TDPUD Program does not permit owner-installed systems. [Rules are necessary if DIY allowed.] 7.1.2 Contractor-Installed System with Separate Seller and Installer In situations where the owner is purchasing the system from one company and hiring a separate company (licensed contractor)for installation, the owner must obtain proof of his or her commitment to purchase and install the system in separate documents as follows: An equipment purchase agreement as described above,or In cases where there is not a signed purchase agreement the owner may provide invoices or receipts showing that at least 10 percent of the system equipment purchase price (generating equipment and inverters)has been paid to the seller(s),and . An installation contract from the second company as described above. [An example of this situation is where the purchaser buys new equipment via the Internet or mail order.] 8. Measurement and Evaluation Requirements To be eligible for Truckee Donner PUD incentives,all Applicants,Host Customers, and System Owners must agree to comply with the terms and requirements of the measurement and evaluation program.This includes providing access to TDPUD and/or third-parties contracted by TDPUD access to the site and any available data and information collected on the system. 9. Definitions and Glossary This section provides a list of acronyms used and definitions of key concepts in this handbook. 9.1 Acronyms Alternating Current(AC): Electric current that reverses direction,usually many times per second. Opposite of direct current(DC). Most electrical generators produce alternating current. Under the TDPUD program,PV electric output calculations must always be made using the CEC-AC rating standards which include inverter DC to AC conversion losses. Applicant: The entity,either the Host Customer, System Owner,or third party designated by the Host Customer,that is responsible for the development and submission of the TDPUD application materials and the main point of communication between the TDPUD Program staff for a specific Application. Azimuth Orientation: Azimuth is the horizontal angular distance between the vertical plane containing a point in the sky and true south. Backup Generators: Backup generators operate as short-term temporary replacement for electrical power during periods of utility power outages. In addition to emergency operation they ordinarily operate for testing and maintenance. Backup generators do not produce enough power to be sold or otherwise supplied to the grid or provide power to loads that are simultaneously serviced by a utility electric grid.Backup generators only service customer loads that are isolated from the grid either by design or by manual or automatic transfer switch. Building Integrated Photovoltaic(BIPV): Building integrated PV systems are solar electric systems in which the PV panels constitute part of the building's roof or facade,replacing conventional building materials.For example, solar shingles may replace conventional asphalt shingles,providing roof protection while producing electricity. Calendar Days: All dates and schedules in the TDPUD program are measured in calendar days, which include all days of the week. California Energy Commission(CEC): California's primary energy policy and planning agency. Created in 1974 and headquartered in Sacramento, the Commission has responsibility for activities that include forecasting future energy needs,promoting energy efficiency through appliance and building standards, and supporting renewable energy technologies. On August 21, 2006,the Governor signed Senate Bill(SB 1)which directs the CPUC and the CEC to implement the CSI program consistent with specific requirements and budget limits set forth in the legislation. California Public Utilities Commission(CPUC): The CPUC regulates a number of industries including the electric utility industry that impact public wellbeing. Among other activities,the CPUC establishes service standards and safety rules and authorizes rate changes.The CPUC, in conjunction Senate Bill 1 (SB 1),has authorized the California Solar Initiative (CSI). In CPUC Decision (D.)06-01-024,the California Public Utilities Commission(CPUC)established the CSI program. In D.06-08-028, the CPUC established implementation details for the CSI program. California Solar Initiative(CSI): portion of customer load that is committed to demand-response programs or on curtailable rate schedules is not eligible for incentives. Design Factor: The Design Factor is a ratio comparing a proposed system's expected generation output with that of a baseline system.The Design Factor is used in calculating the EPBB incentive(it is multiplied by the system rating and the incentive rate to determine EPBB incentives). Direct Current(DC): Electric current in which electrons are flowing in one direction only; which is the opposite of alternating current(AC). Electric Utility: The Host Customer's local electric transmission and distribution service provider for their Site. Electrical Distribution Grid: A network of power stations transmission circuits, and substations conducting electricity.Under the TDPUD program,eligible renewable energy systems must be permanently interconnected and operating parallel to the electrical distribution grid of the utility serving the customer's electrical load. Energy Service Company (ESCO): A business entity that designs, builds, develops, owns,operates or any combination thereof self-generation Projects for the sake of providing energy or energy services to a Host Customer. Energy Service Provider(ESP): An entity that provides electric power and ancillary services(including but not limited to aggregators, brokers, and marketers,but excluding utilities)to an end use customer. Also referred to as an Electric Service Provider. Expected Performance Based Buydown (EPBB): The EPBB incentive methodology pays an up-front incentive to participants installing systems less than 5 kW in size that is based on a system's expected future performance.The EPBB Incentive will be calculated by multiplying the incentive rate by the system rating by the design factor. Firm Service Level: Power supplies that are guaranteed to be delivered under terms defined by contract.For electric utility customers who are on a interruptible or curtailable rate,only generation that serves the portion of their electric load that is designated as firm service is eligible for TDPUD incentives.Under the TDPUD program, Customers must agree to maintain the firm service level at or above capacity of the proposed generating system for the duration of the required applicable warranty period.Customers may submit a letter requesting an exemption to the firm service rule if they plan to terminate or reduce a portion of their available load.

Initially, program data will be updated quarterly. It is anticipated that once fully developed, the database will provide program data on a real-time basis. Non-Residential installations will be provided a one-time payment under the EPBB program to help reduce the cost of installation provided the system size is less than 5 klh'.There are incentive rates are the same for System Owners who are commercial entities or Government or Non-Profit entities. 4.3 Performance Based Incentives (PBl) The Truckee Donner PUD program will not pay PBI for solar projects. 4.4 Incentive Limitations Incentive amounts and project eligibility for the Truckee Donner PUD program are limited by a number of factors, including: Total eligible project costs Other incentives or rebates Project capacity size and Host Customer Site limitations. 4.4.1 Total Eligible Project Costs No project can receive total incentives (incentives from the Truckee Donner PUD program combined with other programs)that exceed total eligible project costs.The Applicant must submit project cost details to report total eligible project costs and to ensure that total incentives do not exceed out-of-pocket expenses for the System Owner. See Section 11 for eligible cost items.Total eligible project costs cover the solar system and its ancillary equipment.Equipment and other costs outside of the project envelope defined in Section 11 are considered ineligible project costs but also must be reported.For large, multifaceted projects where the solar system costs are embedded, applications must include a prorated estimate of the total eligible costs for the solar system. 4.4.2 Other Incentives or Rebates Customers may not receive the Truckee Donner PUD program incentives for the same generation equipment from more than one Program Administrator(e.g.,PG&E, SCE, SDREO).For projects receiving incentives under other programs,the Truckee Donner PUD program incentive may be reduced,depending on the source of the other incentive.For projects that receive"other incentives"for the same generating equipment that are funded by the PUD,the Truckee Donner PUD program incentive is discounted by the amount of the other incentive.For projects that receive"other incentives"funded from other sources than TDPUD utility ratepayers(federal and state grants, air district grants,tax credits,etc.)no adjustment is made to the Truckee Donner PUD incentive. In no event may the combined incentives received from TDPUD program and other funding sources exceed the total eligible project cost. Host Customers,Applicants and System Owners are required to disclose information about all other incentives, including incentives for equipment or systems ancillary to the solar system,post-installation performance payments, or additional incentives.TDPUD program staff may enter applications into a statewide database that wilt permit universal tracking of applications for this and other programs. 2008 63 $2.80 $2.80 2009 71 $2.49 $2.49 2010 81 $2.19 $119 2011 95 $1.86 $1.86 2012 116 $1.53 $1.53 2013 145 $1.22 .`tit.22 2014 181 $0.98 $0.98 2015 227 $0.78 2016 283 50.59 $0.59 2017 354 $0.44 W44 TOTAL ' 161.7 Table 2 Year Kil€awatts Annual"Budget Estimated Systems Itistalled Per Year per year (@ 4kW each) 2008 63 $177,341 15 2009 71 $177,341 17 2010 81 $177,341 20 2011 95 $177341 21 2012 116 $177,341 29 201 3 145 $177,341 36 2014 181 $177.341 45 2{)15 227 $177,341 -56 2016 283 $177.341 70 2017 354 $177.341 88 10-year TOTAL 1617 $1,773,408 399 TDPUD may, at its discretion, adjust the duration of each year/step dependent on: (1)condition of incentive budgets; (2) when the kW step/year goal is reached; and(3) level of program participation. Projects are counted toward the kW goal once they are deemed eligible and have been issued a confirmed reservation. As the number of kW allocated through the confirmed reservations reaches its maximum within any particular year, depending on funding available,TDPUD may suspend the program until the following year or move to the next step, at their discretion. If there are any reserved kW that remain unused in the 3.7 Interconnection to the Electric Utility Distribution System Eligible renewable energy systems must be permanently interconnected to the Truckee Donner PUD electrical distribution grid.Portable systems are not eligible.The system interconnection must comply with applicable electrical codes and the Truckee Donner PUD utility interconnection requirements. The Host Customer,or designate, must also submit an application and enter into an interconnection agreement with the Truckee Donner PUD utility for connection to the electrical distribution grid.Proof of interconnection and parallel operation is required prior to receiving an incentive payment. 3.8 Metering Requirements The Truckee Donner PUD program requires accurate solar production meters for all projects that receive Truckee Donner PUD program incentives.For systems with a system rating of less than 10 kW, a basic meter with accuracy of±5 percent is required.For systems with a system rating of 10 kW and greater, an interval data meter with accuracy of±2 percent is required. An extensive discussion on metering is contained in Section 12. EPBB program participants must provide the Truckee Donner PUD or their authorized agents with physical access to the meter for testing or inspection,and if applicable, data gathering. If the customer's meter is located in a place that is not readily accessible, such access will be by appointment. To avoid inconvenience to customers, installers are encouraged to locate meters in areas that are easily accessible. 3.9 Inspection Requirements It is the intent of the Truckee Donner PUD program to provide incentives for reliable,permanent, safe systems that are professionally installed,and comply with all applicable federal, state, and local regulations. TDPUD,at its discretion, will cotiduct a system inspection visit for every systerii to verify that.the project is installed as represented in the application, is operational, interconnected and conforms to the eligibility criteria of the Truckee Donner PUD program. 3.9.1 Systems that Fail Inspections If a system fails a field inspection,TDPUD will notify the Applicant,Host Customer and System Owner the reasons for the field inspection failure. Such reasons for failure may include but are not limited to the following: Mechanical failure(i.e., one or more of the system components is not operating properly) Verified system is not in compliance with the stated system(i.e., the EPBB characteristics are incorrect,the system components or number of components are incorrect,etc.)and/or the system does not meet the TDPUD program eligibility requirements. If there is a failed inspection for mechanical failures,the Applicant,Host Customer, and System Owner will have 60 calendar days to bring the system into compliance.A subsequent inspection visit will be conducted to determine final approval and will be subject to a re-inspection fee.If the Applicant, Host Customer, and Physical permanence is to be demonstrated in accordance with industry practice for permanently installed equipment.Equipment must be secured to a permanent surface.Any indication of portability, including but not limited to temporary structures, quick disconnects, unsecured equipment, wheels,carrying handles, dolly, trailer, or platform, will deem the system ineligible. Contractual permanence,corresponding to a time period of 10 years, is to be demonstrated as follows: . All agreements involving the generation system receiving an incentive are to be provided to TDPUD for review as soon as they become available(e.g., at the proof-of-project milestones stage or the incentive-claim stage at the latest).These agreements include,but are not limited to, system purchase and installation agreements, warranties, leases,energy or solar services agreements,energy savings guarantees, and system performance guarantees. .The System Owner agrees to notify the Truckee Donner PUD in writing a minimum of 60 days prior to any change in either the site location of the PV system or change in ownership of the generation system if the change(s)takes place within the applicable warranty period.The warranty period for the Truckee Donner PUD program is 10 years. If the PV system is removed prior to the PV panel warranty period,either: —The PV system may be installed at another site within the Truckee Donner PUD service territory within 6 months. The system installed at the alternate site would not be eligible for an additional Truckee Donner PUD program incentive; or —The System Owner would be unable to participate in the Truckee Donner PUD program for any additional installations under the Truckee Donner PUD program, including any active reservations that have not yet been paid. . If the house or business is sold,the new owners can continue to receive the Performance-Based Incentives (PBI) and be eligible to receive future TDPUD program incentives if they complete a new interconnection agreement. If the sellers remove the panels,they can continue to receive the incentive payments and be eligible to receive future Truckee Donner PUD program incentives if the panels they removed are installed within the Truckee Donner PUD's electric service territory within 6 months and they complete an interconnection agreement at the new address. 3.6 Insurance Requirements The Truckee Donner PUD requires insurance as a condition for receiving a Truckee Donner PUD program incentive because,through the Truckee Donner PUD program incentive,the Truckee Donner PUD utility becomes part of the customer's decision(and extended process)to install a solar energy system. Consequently, it is appropriate for TDPUD to impose insurance requirements that will provide protection to those involved in the project and that limit the risk to the PUD(and thus the ratepayers) who fund these projects. 3.6.1 Insurance Requirements for Host Customer and System Owner The Truckee Donner PUD will confirm that equipment identified in a reservation application meets eligibility requirements prior to providing a confirmed reservation notice letter. As described in Section 3.2.1, one exception would be for new equipment that has not yet received certification but for which the process has been initiated.Equipment is periodically added and removed from the lists of eligible equipment so Applicants should confirm that the components purchased for a system are eligible prior to installing them. The Energy Commission certifies modules, system performance meters,and inverters.The system must be interconnected to the grid, and inverters and modules must each carry a 10-year warranty.Eligibility requirements for components are summarized below: -PV modules must be certified to UL 1703 by a nationally recognized testing laboratory (NRTL). -Performance meters must measure kWh(or Watt hours) with a manufacturer's uncertainty of±5 percent,retain data in the event of a power outage,and be easy to read for the customer's benefit. -Inverters must be certified to UL 1741 by a NRTL.They also must have completed the Energy Commission's required weighted efficiency testing. 3.2.5 System Size The minimum system size eligible for an incentive is 1 kW.The maximum incentive provided under the Truckee Donner PUD program is for a system size of 5 kW. The system size must be calculated using the CEC-AC rating standards, including inverter DC-to-AC losses and a design factor.To calculate the CEC- AC rating, the following formula should be used: System Rating(kilowatts)=Quantity x CEC Rating of Photovoltaic Modules x CEC Inverter Efficiency Rating/ 1000(watts/kilowatt) System size= System Rating x Design Factor The Design Factor is defined as: Design Factor=Proposed System/Baseline System The Design Factor will: Account for shading Assign optimal orientation tilt for each compass direction Include location specific criteria to account for weather variation Determine optimal reference latitude tilt that relates to local latitude. Pending the Truckee Donner PUD approval,the maximum incentive provided for a Host Customer Site under the Truckee Donner PUD program is for a system size,of 5 kW; however, a Host Customer Site may elect to install up to 2 MW of generation. Although not required, installation contractors are encouraged to become certified by the North American Board of Certified Energy Practitioners(NABCEP).For additional information on NABCEP,go to www.nabcep.org. In all cases, systems must be installed in conformance with the manufacturers' specifications and with all applicable electrical and building codes and standards. To participate in the Truckee Donner PUD program,companies that install system equipment must be certified by the CEC according to the CEC Certification process.The CEC process will request the following information to be submitted to the CEC: Business name, address,phone,fax, and e-mail address Owner or principal contact Business license number Contractor license number(if applicable) Proof of good standing on the records of the California Secretary of State, as required for corporate and limited liability entities .Reseller's license number(if applicable) Proof of CEC Certification must be submitted to the Truckee Donner PUD before a company can become eligible to participate in the Truckee Donner PUD program, and must maintain Certification to continue participation in the Truckee Donner PUD Program. TDPUD also requires installers to answer additional questions regarding credentials,experience, and education in the installation of grid-tied PV systems. 3.1.5 Equipment Sellers To participate in the Truckee Donner PUD program,companies that sell system equipment must also be certified by the Energy Commission.The Energy Commission requests the following information on their form CEC-1038 R4: Business name, address,phone, fax, and e-mail address Owner or principal contact Business license number Contractor license number(if applicable) Proof of good standing on the records of the California Secretary of State, as required for corporate and limited liability entities . Reseller's license number This information must be submitted to the Energy Commission before a company can become eligible to participate in the Truckee Donner PUD program. 3.2 Generator System Equipment Eligibility Currently, only PV systems(i.e., systems that cause direct conversion of sunlight to electricity) are eligible to receive incentives from the Truckee Donner PUD program. Details of the eligibility requirements for generation system equipment follow. determine the system's capacity rating. The system rating will be multiplied by a design factor that will consider certain factors (i.e., location,orientation, and shading)that have an influence on system performance. 2.4.1.1 EPBB for New Construction All Non-Residential new construction projects will be paid EPBB incentives.Residential new construction projects will be funded through the New Solar Homes Partnership(NSHP)administered by the Energy Commission.Pending a state decision,new construction projects for mixed-use property,properties with both commercial and residential units, may be eligible for the Truckee Donner PUD program. 3. Program Eligibility Criteria and Requirements The Truckee Donner PUD program offers monetary incentives for systems up to the first 5 kW of alternating current generated by an eligible solar energy system. To qualify for incentives,all Truckee Donner PUD program eligibility criteria must be satisfied.The effective dates for the Truckee Donner PUD program are January 1, 2008 through December 31, 2016 or until the Truckee Donner PUD program budget has been fully reserved. 3.1 The Participants in the Truckee Donner PUD Program Any retail electric distribution customer of the Truckee Donner PUD is eligible to install a solar project and receive incentives from the program.Within the nomenclature of the program,the person who applies for an incentive will be referred to as an Applicant, a Host Customer, and/or a System Owner. 3.1.1 Host Customer Any retail electric distribution customer of the Truckee Donner PUD is eligible to install a solar project and receive incentives from the program and can, therefore,be a Host Customer. The Host Customer must be the utility customer of record at the location where the generating equipment will be located.Any class of customer is eligible to be a Host Customer.The project's Site must receive retail level electric service from the Truckee Donner PUD. The Host Customer becomes the incentive reservation holder.The Host Customer may act as the Applicant and/or System Owner.The Host Customer alone will retain sole rights to the incentive reservation and corresponding incentive reservation number. A reservation for a specific Site is not transferable.The Host Customer has the right to designate the Applicant,energy services provider, and/or system installer to act on their behalf. However,the Host Customer shall be party to the Truckee Donner PUD program contract. To be eligible for an incentive,the Host Customer or Applicant must receive a confirmed reservation notice letter from the Truckee Donner PUD prior to the Applicant receiving final interconnection authorization from the PUD to operate the project in parallel with the grid. If a project cancels due to not meeting the reservation period,they must reapply to the Truckee Donner PUD program prior to receiving a final interconnection authorization from their utility to operate the project in parallel with the grid. 7. The solar Program funds cannot be taken from any existing programs for low-income ratepayers, or from cost-effective energy efficiency or demand response programs. 8.The expenditure level for each utility is based on that utility's percentage of the total statewide load served by all local publicly owned electric utilities.Expenditures by a utility may be less than the utility's cap amount,provided that funding is adequate to provide the incentives required All of the solar photovoltaic systems that are allowed to be incented under the Truckee Donner PUD's solar program are to be consistent with rules to be established under Chapter 25782 of the Public Resources Code. The development of these Rules is in process at the California Energy Commission,but the Rules have been substantially developed as of this date.These rules are required to be put into place by January 1, 2008 and include the following items(summarized): (1)Design,installation,and electrical output standards. (2)The solar system is intended primarily to offset part or all of the consumer's own electricity demand. (3)All components in the solar energy system are new and unused (4)The system has a warranty of at least 10 years. (5)The solar system is located where the consumer's own electricity demand is located. (6)The solar system is connected to the Publicly-Owned utility's electrical distribution system within the state. (7)The solar system has meters or other devices that measure system performance and the quantity of electricity generated. (8)The solar system is installed in conformance with the manufacturer's specifications and in compliance with all applicable electrical and building code standards. SB-1 further requires that solar electric systems meet performance requirements in order for the system to be eligible for an incentive.These performance requirements must meet all of the following, which are currently being developed by the CEC: (1)Appropriate siting and high quality installation of the solar energy system by developing installation guidelines that maximize the performance of the system and prevent qualified systems from being inefficiently or inappropriately installed. (2)Optimal solar energy system performance during periods of peak electricity demand. (3)Appropriate energy efficiency improvements in the new or existing home or commercial structure where the solar energy system is installed. (4)Rating standards for equipment,components,and systems to assure reasonable performance and standards that provide for compliance with the minimum ratings. 2.0 Program Design Overview The SB-1 compliant solar program for Truckee Donner PUD has been designed by Efficiency Services Group.This program has been designed with the following principles in mind: 1.The Program is fully compliant with SB-1 law and with rules promulgated by the California Energy Commission under direction of the law. Where rules are still being developed,the Program will evolve to match those rules. Where rules and practices are still being interpreted, interpretations consistent with CMUA and NCPA member working groups will be utilized. 2.The Program enlists and utilizes the best examples of processes,procedures,and paperwork(forms, brochures)already designed and in use by other utilities(best practices/no reinventing the wheel) 3.The Program is consistent, inasmuch as it can save the utility time and money, with programs of larger utilities (notably PG&E) with territory surrounding utility members,especially in regard to solar contractors 12.4 Independence of Performance Monitoring &Reporting Service Provider 12.5 Eligible Recipients of Information 12.5.1 System Owner 12.5.2 Truckee Donner PUD 12.5.3 Data Privacy 12.6 Advanced Metering Infrastructure Coordination 12.7 Overall Cost Constraint 13.

Truckee Donner PUD provides rebates to its customers to reduce the initial system cost. All California utilities are required to collect Public Benefits Funds from their customers.These funds are to be used by the utilities to develop and implement public purpose programs such as photovoltaics. Truckee Donner PUD is committed to promoting and supporting renewable technologies and is offering its customers rebates to reduce the purchase and installation costs for PV systems and a net metering credit for producing solar electricity. The Truckee Donner PUD's PV Program uses its customer funds to provide these solar incentives. To obtain the best value for our customers,the Truckee Donner PUD PV Program is designed to encourage the installation of PV Systems that produce the maximum amount of energy possible, so our Program incentive is calculated based on an Estimated Performance Calculation. ELECTRICITY FROM THE SUN Photovoltaics is the direct conversion of light into electricity. Certain materials,like silicon, naturally release electrons when they are exposed to light,and these electrons can then be harnessed to produce an electric current. Several thin wafers of silicon are wired together and enclosed in a rugged protective casing or panel. PV panels produce direct current(DC)electricity, which must be converted to alternating current(AC)electricity to run standard household appliances.An inverter connected to the PV panels is used to convert the DC electricity into AC electricity. The amount of electricity produced is measured in watts(W).A kilowatt(kW) is equal to 1,000 watts.A Megawatt(MW)is equal to 1,000,000 Watts or 1,000 Kilowatts. The amount of electricity used over a given period of time is measured in kilowatt-hours (KWh). HOW DOES THE BUYDOWN PROGRAM WORK? The amount of the rebate is based on the Estimated Performance(kilowatthour production) of the system,and converted to the effective annual AC generating capacity of the PV system measured In AC watts. The rebate amount for 2008 is$2.80 per AC watt for systems up to a maximum size of 4 kilowatts(residential)and 5 kilowatts(commercial). Currently,the total amount available for rebates the first year is approximately$177,300 for all installations. Rebates are available on a first come,first served basis and are limited to$11,200/residence and$14,000/commercial installation. Customers may apply for multiple incentives over the 10- year lifetime of the program.
