Energy Commission's Solar Equipment Lists

Effective August 21, 2019, the listing request forms used to request listing of Battery and Energy Storage Systems (ESS) to the Energy Commission's Solar Equipment Lists have been uploaded. The new forms and instructions are available on the GoSolarCalifornia website, on the specific equipment page Battery and Energy Storage Systems (ESS). In addition, the List of Inverters (Grid Support and Utility Interactive) has been modified. Also, the Photovoltaic (PV) Module Listing Request Instructions and the Inverter Listing Request Instructions are updated. These pages can be accessed below.

Please note that the Energy Commission's Solar Equipment Lists updates are typically completed twice a month, on the 1st business day of the month and the 15th of the month or the following business day.

Submit inquiries regarding the Energy Commission's Solar Equipment Lists to the California Energy Commission at For any equipment listing related questions, please contact the Solar Equipment Call Center at 916-654-4120.

All solar energy systems receiving ratepayer-based incentives in California must utilize equipment listed on these pages and maintained by the Energy Commission. The enactment of Senate Bill 1 (Murray) in 2006, directed the Energy Commission to establish eligibility criteria, conditions for incentives, and rating standards for projects applying for ratepayer-funded incentives for solar energy systems. The Energy Commission's Solar Equipment Lists include PV modules, inverters (including smart inverters), meters, battery and energy storage systems, and related equipment. Please note that equipment on the Energy Commission's lists have undergone tests to achieve minimal safety and performance standards. The Energy Commission and the State of California make no claim or warranty on the equipment and its safety, performance or durability. Anyone considering installing solar energy systems are encouraged to conduct their own research.
