In addition, customers may pay an additional 10% reservation fee at contract signing to reserve a spot near the front of the installation queue in their community. The remaining cash payment including sales tax is required upon delivery of materials. For systems financed by a loan or other third party, SolarCity will refund the 10% deposit once it has received payment in full for the total system cost. The customer is responsible for seeing that SolarCity is paid in full upon completion of installation of their PV Solar System. Completion of installation occurs when all of the required. hardware (except monitoring systems) has been installed and is prior to inspection and grid interconnection. Estimated Rebates While SolarCity makes good faith estimates on rebates, actual rebates are subject to change by the government based on the total installed capacity in California and final installed configuration. The customer is responsible for paying the entire balance due under this Agreement. As such, should the actual rebate received by SolarCity be lower than the estimated rebate provided for in this Agreement, the customer will pay the difference between the actual and estimated rebate to SolarCity. Unforseen modifications . -SolarCity makes its best estimate in providing a quote that reflects the total number of solar panels to be installed. However, subsequent to the execution of this Agreement, a mandatory engineering and design audit required to ensure your system is fully optimized may reveal that a change in the number of solar panels is necessary. Where such a change in the overall system size is required, SolarCity will consult with the customer and issue an amended purchase order to reflect the proportional increase or decrease in the system price. -In addition, solar panel module costs are subject to high volatility. Should such volatility result in an unanticipated increase in the total system cost provided for in this Agreement, Solarcity reserves the right to adjust the contact price to reasonably reflect the increase in cost of the solar panel modules. If the adjusted contract price is not acceptable to the customer. the customer may void this contract. in which case. SolarCity will refund all deposits paid by the customer. -In addition, for systems that require digging or trenching: If SolarCity encounters unforseen subsurface conditions (including but not limited to rocks, utilitiy lines, tree roots and other impediments) SolarCity will be required to pass on the added unanticipated costs to the customer. Communication SolarCity's primary mode of communication with customer will be through email unless requested otherwise Permit Fees Permit fees are not included in this price. SolarCity will pay for the permit fees to expedite processing. However customer will need to reimburse SolarCity upon delivery of materials.

Of Public Works Los Altos Hills, CA 94022 Proposal for Los Altos Hills Town Hall Subject: Engineering/Installation of Three (3) Photovoltaic (PV) Solar Dual -Axis Motor -Driven Tracker System at Los Altos Town Hall Sol'arCity is proud to present the following proposal for the Los Altos Hills Town Hall, per request for proposal (second) from Henry Louie. I have included pricing for both EPBB and PBI structure. Due to the increased output of a Dual Axis Tracker System, I highly recommend the PBI structure, as evidenced by the IRR and ROI numbers. Included with this cover letter is: (1) Proposal for "Dual Axis Tracker PV" system - Comprehensive proposal that includes 48 Sanyo HIP200BA3, 205 -Watt modules and three Xantrex 3,800 Watt inverters, designed to produce 8,824 peak AC Watts, and 18,900 kWH per year. System will be mounted on three, dual -axis Wattsun Trackers. (2) EBPP 1 -page summary for "Dual Axis Tracker PV" system -- Illustrates equipment to be used, costs, expected rebate, and projected financial benefits of opting for the CSI's up front cash rebate, including: (a) 9.1% rate of return (b) Net cumulative savings after 25 years of $158,,981 (c) System payback after year 11 (3) PBI 1 -page summary for "Dual Axis Tracker PV" system -- Illustrates equipment to be used, costs, expected rebate, and projected financial benefits of opting for CSI's performance based incentive, including: (a) Out of Pocket cost of $78,530 (b) 10.6% rate of return (c) Net cumulative savings after 25 years of $206,675 (d) System payback after 7.4 years Note: The ROI and IRR are based on Los Altos Hills Town Hall's estimated energy usage and PG&E metering system; This information was not included in the RFP. With more accurate information, I am happy to include a more accurate ROI. Assumes we offset electricity that in 2006 averaged 16 cents/kWh (based estimation); a 6.5010 annual increase in cost of electricity (a CA Energy Commission SolarCity Corp. Confidential Page 1 IEY.- ti I t5` 010C k1 study of rate increases from 1970-2001 found a 6.7% annual increase, so this is slightly conservative); and an annual average of 5.3 sun hours/day. (4-6) Spec sheets for the Wattsun Tacker, Sanyo module and Xantrex inverter -- The modules are warrantied by Sanyo for 20 years; the inverters by Xantrex for 10. (We have every indication to believe that the system will last 30+ years: the original Bell/RCA labs' PV modules are over 50 years old and still functioning at about 50% capacity, and accelerated testing of today's technology shows a performance lifespan of 30+ years.) You will likely need to replace the inverter around year 15, which is included in the financial analysis. The Wattsun dual axis tracker has a 5 year warranty. Due to the nature of dual -axis trackers, our 10 year umbrella warranty will not cover the dual axis trackers. (7) CA Solar Initiative (CSI) rebate calculations -- The CA Solar Initiative's. "Expected Performance -Based Buydown" (EPBB) rebate calculator results -- Illustrates expected performance and rebate award for the system, at $28,017. The rebate is calculated by multiplying the CEC-AC rated output (7,484 Watts) by $2.50, then by the "Design Factor) which is .98 in your case (we are basing this on the removal of the aforementioned tree). We thus arrive at a rebate amount of $3.18/Watt. Please let me know if you have any questions about how the EPBB calculator arrives at this figure. Unfortunately,, the CSI Calculator does not have a way to compensate for dual axis trackers; Therefore the proposals" estimated annual outputs have been adjusted. (8) SolarCity Project Management — SolarCity recognizes that in order to offer the best price, with the highest quality; Project Management is key. Therefore we have developed processes that will ensure that no matter how large we grow, we will maintain high quality. In addition to .our Project Management Processes, we have developed our own software for managing jobs. We also use the best equipment for design: All installations on done in Auto -CAD; Engineering site sudit using Tablet Computers, Solmetric Suneye for accurate sunreadings; Nextel for the best communication.

The CSI-EPBB calculator is a tool available to the public and participants of the CSI program, whose sole purpose is to determine the EPBB Design Factor and calculate an appropriate incentive level based on a reasonable expectation of performance for an individual system. The results of the calculator should not be interpreted as a guarantee of system performance. Actual performance of an installed PV system is based on numerous factors, and may differ with the results summarized in the CSI-EPBB calculator. For this reason, contractors, participating customers, and other interested parties should only utilize the calculator to determine an appropriate incentive when applying to the CSI incentive program. Additional uses for the calculator other than its intended purpose as stated above are not endorsed or en... .couraged. Notes: 1.

The CSI-EPBB calculator is a tool available to the public and participants of the CSI program, whose sole purpose is to determine the EPBB Design Factor and calculate an appropriate incentive level based on a reasonable expectation of performance for an individual system. The results of the calculator should not be interpreted as a guarantee of system performance. Actual performance of an installed P/ system is based on numerous factors, and may differ with the results summarized in the CSI-EPBB calculator. For this reason, contractors, participating customers, and other interested parties should only utilize the calculator to determine an appropriate incentive when applying to the CSI incentive program. Additional uses for the calculator other than its intended purpose as stated aboveare no.. . ...... .. -t endorsed or encouraged. .. ..Notes: 1. Design Correction: This is the ratio of the summer output of the proposed system (e) and the summer output of the summer optimal system at the proposed location (f). a . I of 2 3/15/2007 3:33 PM CSI EPBB Calculator http://www.csi-epbb.com/Default.aspx 3. Design Factor: This is the product of the Design Correction and Geographic Correction. 4. Eligible Incentive Rate: This is the product of the Design Factor and the current CSI EPBB reference incentive rate (which depends on the selected utility and customer type). 5. Incentive: This is the total incentive for the proposed system. It is the product of the CEC-AC Rating and the Eligible Incentive Rate. 6. While the displayed results have been rounded for clarity, all calculations use full precision. Attempting to calculate the total incentive using the displayed system rating and design factor may result in differences due to rounding. E-mail CSI-EPBB@aesc-inc.com with questions or comments.
