Include all areas of the project built by the developer in the estimated demand. To calculate the energy contributions from the photovoltaic system, use calculations from the New Solar Homes Partnership Calculator, or from another CEC-approved calculation method. The estimate must include system size, expected output of the system, and an estimate of the amount of the total electrical load that will be offset by the photovoltaic system. VERIFICATION Field Verification: The Rater will conduct field compliance verification to confirm that the installed system meets the specified system, and take photos of the system. Documentation: The Rater will collect the following: Copies of energy compliance reports Calculations of total of home energy use based on compliance threshold An estimate of renewable energy production using documents identified in the Criteria for Qualification section of this measure, and the percentage of renewable contribution from the builder or another appropriate expert. The contractor must supply a copy of the CF-6R-PV solar report (or other appropriate forms) based on what was actually built (that is, the system size, output, and percentage of load served by the photovoltaic system). If a HERS Rater is completing the inspection, he or she will provide the CF-4RPV after installation. INTENT To conserve fossil fuels used for electricity generation and reduce pressure on the electrical grid by using renewable energy sources.
