Note: AB 217 of 2013 made several changes to this program. Among other changes, the expiration date was extended to December 31, 2021 or whenever funds are exhausted, and the budget was increased. Specifiically, the bill added an additional $108 million to be divided between the SASH and MASH programs. As of August 2014, the California Public Utilities Commission (CPUC) is implementing these legislative changes through proceeding R. 12-11-005.

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.

Twenty percent of the total funds for the SASH program ($21,668,000) will be dedicated to providing fully subsidized 1 - 1.2 kW systems to qualifying households. Qualifying households are owner-occupied and the total income for the household is up to 50% of AMI. Households making more than 50% of AMI, but less than 80% of AMI can be eligible for a partially subsidized system according to the following table:
