3. A copy of the executed contract for the installation of the solar system. 

As part of California Public Utilities Commission (CPUC) Decision D.18-09-044, interconnection applicants submitting solar net energy metering interconnection applications on behalf of existing residential single-family-home customers on or after September 30, 2019, are required to upload the following documents to the utility’s interconnection application portal: 1) customer-initialed and customer-signed pages of the California Solar Consumer Protection Guide, 2) a completed Contractors State License Board (CSLB) Solar Energy System Disclosure Document; and 3) a copy of the executed contract for the installation of the solar system. Existing residential single-family-home applicants with an installation contract signed on or before September 30, 2019, are required to upload only the signed installation contract. These documents may be subject to periodic review or audit by either the utility, the CPUC, or the CSLB (depending on the document type).

Prevailing Wage Disclosure (Form 16-333)⁴ 

As part of CPUC Decision D.23-11-068, the purpose of prevailing wage laws is to ensure fair competition among contractors and to protect the wages of workers. Interconnection applicants submitting any application on behalf of existing residential and/or commercial customers on or after 1/1/2024 are required to complete the Prevailing Wage Checklist, submit a Prevailing Wage Disclosure Form (if applicable), and certify that past required submittals of payroll records are up to date.

Electrical System Sizing Documentation (new/expanded loads greater than the previous 12-month usage history)

If the estimated production based on the NEM Interconnection Handbook calculation is greater than the previous 12 months’ usage, an electrical system sizing document must be submitted as follows:

• Customer System Size Acknowledgment (CSSA) Form: Applicable to residential systems sized 30 kW and smaller only. Not accepted for New Construction or Non-Residential projects.
• Load Justification Form: The form must be fully completed and submitted with proof of purchase and installation.
• Building Simulation Report: i.e., ECON1, UTIL1, EQUEST, or professional engineering report.

Net Billing Tariff:

• Attestations: Selected in the Interconnection Application. 

Net Billing Tariff Aggregation or Net Energy Metering Aggregation (Form 14-937)

The primary account listed is the account or new service the RGF is interconnected; the benefitting accounts are the meters that are contiguous and adjacent to the parcel of land the RGF is on.

Virtual Net Billing Tariff, Virtual Net Energy Metering for Multi-Tenant and Multi-Meter Properties Allocation Request Form (Form 14-910)
