These guidelines are an available resource for learning about the requirements for the solar equipment lists.

The solar equipment lists and instructions on how to add equipment to these lists are on the Go Solar California website equipment page.

A chronicle of official records for regulatory proceedings related to the solar equipment lists.

The California Energy Commission developed the solar equipment lists under Senate Bill 1 (Murray, Chapter 132, Statutes of 2006), establishing criteria and standards for solar projects applying for ratepayer-funded incentive programs under the California Solar Initiative. To ensure the solar equipment met minimum safety and performance standards, the Energy Commission created lists of solar equipment, including photovoltaic modules, inverters, meters, performance monitoring and reporting systems, and other solar energy-generating systems.

The purpose and use of these equipment lists have expanded over time from initially supporting solar incentive programs. These lists provide useful equipment information and data for users who use the list for purposes such as researching, modeling, validating interconnection requirements by utilities, integrating smart inverters, and supporting existing or expanded solar incentive programs.

The Energy Commission is exploring opportunities to expand the current solar equipment lists to include other technologies, such as battery storage, to be responsive to the solar market and industry needs.
