Solar Electric System Requirements

Energy Storage Systems shall be listed to UL 9540 or successor standards and shall be certified by the California Energy Commission, except with program pre-approval.

Does a building need a battery storage system?

All buildings that are required by Section 140.10 (a) to have a PV system shall also have a battery storage system meeting the minimum qualification requirements of Reference Joint Appendix JA12. The rated energy capacity and the rated power capacity shall be not less than the values determined by Equation 140.10-B and Equation 140.10-C.

Which building types require a photovoltaic (PV) system?

All newly constructed building types specified in Table 140.10-A, or mixed occupancy buildings where one or more of these building types constitute at least 80 percent of the floor area of the building, shall have a newly installed photovoltaic (PV) system meeting the minimum qualification requirements of Reference Joint Appendix JA11.

Can a battery storage system be used as a standalone system?

A battery storage system can be installed as a standalone system for additional compliance credit, when not required prescriptively. Also, a battery system larger than the prescriptive requirement can be used to tradeoff for a smaller solar PV system. Are There Exceptions? Yes.

What is the required battery storage system size?

The required battery storage system size is based on the solar PV system size determined for building types listed in Table 140.10-B, including mixed-occupancy buildings. The total capacities of a battery storage system shall be no less than those calculated from the equations above.

Do solar systems need polarity & energy storage regulations?
