■ Calculated CSI system size by the spreadsheet—1032 kW ac
■ Inverter—Xantrex Technology Model PV225S-480P
■ Power output capacity—225 kW ac
■ Efficiency—94.5 percent
■ Resulting output = 1057 × 94.5% = 999 kW
■ CSI EPBB Design Factor = 0.975
■ CSI system size = 999 × 0.975 = 975 kWh
■ PV system daily output = 957 × 5.63 (insolation) = 5491 kWh/day
■ Annual system output = 5491 × 365 (days) = 2,004,196 kWh/yr

Assuming an incentive class for a government or nonprofit organization for year
2007, the allocated performance output per kilowatt-hour = $0.513.

■ Total incentive over 5 years = 2,004,196 × $0.513 = $1,028,152.55
■ Projected installed cost = $8,500,000.00 ($8.50/W)
■ System owner’s out-of-pocket cost = $3,489,510.00
■ Application fee of 1 percent of incentive amount = $50,105.00

Equipment Distributors

Eligible manufacturers and companies who sell system equipment must provide the
CEC with the following information on the equipment seller information form (CEC-
1038 R4). For all CEC approved equipment see Appendix C. Figure 8.6 is a sample of
Southern California Edison CSI final project cost affidavit.

■ 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 in the records of the California secretary of state, as required
for corporate and limited liability entities
■ Reseller’s license number

Special Funding for Affordable

Housing Projects

California Assembly Bill 58 mandates the CEC to establish an additional rebate for
systems installed on affordable housing projects. These projects are entitled to qualify
for an extra 25 percent rebate above the standard rebate level, provided that the total
amount rebated does not exceed 75 percent of the system cost. The eligibility criteria
for qualifying are as follows:
