Energy Storage System (ESS)

Submitted information is reviewed by the California Energy Commission prior to equipment being added to the Energy Commission's Solar Equipment Lists but it is not continuously monitored. The California Energy Commission does not confirm manufacturers' self-reported information. Please note that equipment on the Energy Commission's Solar Equipment Lists have undergone tests to achieve minimal safety and performance standards. The California 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.


For information on equipment eligibility and required laboratory-tested data, please refer to the SB 1 Guidelines, Appendix B.
