California Solar Initiative


During 2006-16, CSE administered the general market portion of the California Solar Initiative (CSI) for the California Public Utilities Commission, providing rebates for photovoltaic (PV) systems for residential and commercial utility customers in the San Diego Gas & Electric (SDG&E) territory.

Through the program, CSE awarded more than 19,300 rebates totaling over $191 million to help businesses, nonprofit organizations, public agencies and homeowners lower their energy costs, reduce their reliance on fossil fuels and create a sustainable energy future supported by solar technologies in the San Diego region. We also offered educational programs, professional training, conferences and other activities aimed at promoting the widespread adoption of solar PV, the growth of a strong solar industry and the development of supportive solar policies and regulations.

Today, CSE draws upon the expertise and experience we gained as CSI program managers to assist consumers nationwide through our Center for Solar Energy.
