The California Solar Initiative (CSI) is the solar rebate program in California for customers of the investor-owned utilities: Pacific Gas and Electric, Southern California Edison and San Diego Gas & Electric. Through CSI, the California Public Utilities Commission is providing $2.1 billion to businesses, nonprofit organizations, public agencies and homeowners to help lower their energy costs, reduce their reliance on fossil fuels and create a sustainable energy future through the use of solar technologies.
The CSI Program is directly administered by each investor-owned utility, with the exception of SDG&E, whose CSI program is administered by CSE.
The CSI Program Handbook describes the detailed requirements for receiving incentives for the installation of solar energy systems under the CPUC-managed incentive programs: solar photovoltaic (PV), solar thermal (solar water heating), multifamily affordable solar housing (MASH), single-family affordable solar housing (SASH) and other solar applications.
