1 Presented By: SOLAR ELECTRIC ANALYSIS FOR: Jack Sun Recommended System Size 10.6 kw PV System at 117 So Mary Ave, #30 Sunnyvale, CA 94087

2 WHY GO SOLAR? Enjoy clean, renewable energy from the Sun Enjoy attractive ROI Own your own generator Enjoy improved cash flow Reduce electric bills Protect from rising electric bills Clean, unlimited resource from the Sun Increase property's resale value Less dependent on fossil fuels and imported oil Reduce harmful emissions: CO 2, SO x, NO x, Particulates ` Enjoy interesting new technology Become a solar ambassador Reap PV benefits for current or future electric car ownership

3 CURRENT ELECTRIC USAGE AND BILLING Current Electric Usage 18,000 kwh /yr Current Rate Schedule E1 Monthly Bill (Before Solar) $ 403 /mo Annual Bill (Before Solar) $ 4,832 /yr

4 HOW SOLAR ELECTRIC SYSTEMS WORK DAY: 1 Sunlight falls on PV array generating DC electricity. 1# 4# 2 Inverter converts DC electricity into AC electricity. 3 AC electricity generated goes to appliances or lights. Excess electricity goes to the utility grid spinning your electric meter backwards. 2# 3# 4 This reduces electric usage from the utility grid, and reduces your electric bill. This happens silently and automatically everyday. NIGHT: 1,2 Solar system's output stops. 1#. 4# 3,4 Building gets the electricity directly from the utility grid. Time-Of-Use metering takes advantage of higher daytime electric rates, allowing you to sell power at a high rate, and buy it back at night at a lower rate. 2# 3# This gives you the same reduction in your electric bill but with a smaller solar system, reducing the system's cost.

5 PROPOSED SOLAR ELECTRIC SYSTEM 10.6 PV system size (STC DC Rating) Comprising 47 SunPower SPR-225E-BLK-U-ACPV modules and 3 SMA America SB3000US (240V) inverters. PV Array is 22 up from horizontal, and facing South % ,987 Hours of equivalent full noontime sun occurs at Sunnyvale, CA Total system efficiency factor, accounting for inverter, module temperature, wire losses, dust & dirt, and module mismatch factors Hours of effective equivalent full noontime sun, factoring in shading & orientation kwh/year estimated production (1,629 kwh per year per kw CEC AC Capacity Rating) Offsets about 83% of estimated/adjusted future usage

6 ESTIMATED PRODUCTION, USAGE, AND NEW BILL Current Electric Usage 18,000 kwh /yr Estimated Annual PV Production 14,987 kwh /yr Suggested Rate Schedule with Solar E6 Estimated New Monthly Bill with Solar $ 13 /mo Estimated New Annual Bill with Solar $ 150 /yr

8 ANNUAL SAVINGS WITH SOLAR Without Solar With Solar Year Old Bills New Bills 1 $4,832 $150 2 $4,977 $154 3 $5,126 $157 4 $5,280 $161 5 $5,438 $164 6 $5,601 $168 7 $5,769 $172 8 $5,943 $176 9 $6,121 $ $6,304 $ $6,494 $ $6,688 $ $6,889 $ $7,096 $ $7,309 $ $7,528 $ $7,754 $ $7,986 $ $8,226 $ $8,473 $ $8,727 $ $8,989 $ $9,258 $ $9,536 $ $9,822 $256 Savings $4,681 $4,823 $4,969 $5,119 $5,274 $5,433 $5,598 $5,767 $5,941 $6,121 $6,306 $6,496 $6,693 $6,895 $7,103 $7,318 $7,539 $7,767 $8,001 $8,243 $8,492 $8,749 $9,013 $9,285 $9,566 New Bills and Electric Bill Savings with Solar $12, $10, $8, $6, $4, $2, $ Electric Bill Savings with Solar New Bills

9 PV SYSTEM COST AND INCENTIVES Gross System Price $58,163 Incentives: U.S. Fed Tax Credit / Grant Net value of Rebates ($17,047) ($1,840) Fees not included in system contract price Net System Cost $500 $39,776

10 ECONOMICS AND RETURNS Electric Bill Savings 1st-Year Savings $4, Year Cumulative Net Savings $141,763 Pre-Tax Compound Annual Rate of Return (IRR) over 25 years 22.7% Total Lifecycle Payback 3.6x Simple Payback 8.1 years Estimated Initial Increase in Property Value $90,720 Estimated Maximum Resale Value increase occurs at year 8 $105,708 Disclaimer: This information is provided as an illustration of potential financial benefits stemming from ownership of a renewable energy power system. This is not a production guarantee. A professional accountant or tax advisor should confirm these estimates. Neither nor OnGrid Solar warrants the applicability of these estimates for particular business cases, and both disclaim all liability.

11 ESTIMATED RESALE VALUE A home's value increases by $20,000 for every $1,000 reduction in annual operating costs efficiency (according to the Appraisal Journal) $180,000 $160,000 $140,000 Resale Value Over Time Rationale: Money from reduction in operating costs can be spent on larger mortgage with no net change in monthly cost of ownership (to a future buyer) Resale value increases over time as electric bill savings increases due to escalation Resale Value $120,000 $100,000 $80,000 $60,000 $40,000 $20,000 Maximum value is likely capped at remaining savings before system is out of module warranty (25 years) Years $ Remaining savings within 25 years Effective Resale Value 20 times Annual Savings

12 SMART FINANCING Smart Financing with a Line of Credit versus inefficent or optimistic simple loans: Interest Rate: 7.5% Term: 30 years Inefficient Loan Smart Financed Loan Optimistic Loan Amount Borrowed: $56,822 $56,822 $39,776 Customer Out-of-Pocket Expense: Monthly Payment (before interest tax deduction): $0 $0 $17,047 $401 $289 $281 Smart Financing results depend on all tax incentives being applied to loan principal when received. Hence, no money out of pocket, but also, no money wasted on unnecessary interest.

13 CASH FLOW IF FINANCED Year 1 Year 2 Year 5 Year 10 Solar Cost with Smart Financing $2,172 $2,672 $2,857 $3,238 Old Electric Bill with inflation $4,832 $4,977 $5,438 $6,304 Cash Flow (Annual) $2,660 $2,305 $2,581 $3,066 $12,000 $10,000 Annual Costs: Solar plus Financing vs. No Solar Annual Cost $8,000 $6,000 $4,000 $2,000 Years $ Old Utility Bill w/ 3.0% inflation Solar Cost w/ Financing
