California Solar Initiative - Single-Family Affordable Solar Housing (SASH) Program

May 18, 2023


Note: As of June 2022, this program is fully subscribed in the service territories of all three investor-owned utilities: Pacific Gas & Electric, Southern California Edison, and San Diego Gas & Electric.   

The California Solar Initiative (CSI), enacted by SB 1 of 2006, provides financial incentives for installing solar technologies through a variety of smaller sub-programs. Of the $3.2 billion in total funding for the CSI, $216 million has been set aside for programs to help fund photovoltaic (PV) installations on low-income housing. Half of that $216 million is funding the Multi-Family Affordable Solar Housing (MASH) program, and the other half is funding the Single-Family Affordable Solar Housing (SASH) Program. The SASH program is being administered on behalf of the investor-owned utilities by GRID Alternatives. Income-eligible customers of Pacific Gas and Electric (PG&E), Southern California Edison (SCE) and San Diego Gas and Electric (SDG&E) may participate. In general, the household's total income must be 80% of the area median income (AMI) or less.

Before a PV system is installed through the SASH program, all appropriate energy efficiency measures should be pursued.
