Multifamily Affordable Solar Housing

CSE administers Multifamily Affordable Solar Housing (MASH) Program incentives in San Diego Gas & Electric (SDG&E) territory. The goal is to combine energy efficiency and solar photovoltaic (PV) to help improve the overall quality of affordable housing and decrease energy use and costs for occupants.

Through MASH, the California Public Utilities Commission set aside $162 million to assist multifamily, low-income housing in offsetting the cost of installing PV systems on multitenant affordable housing developments in California. MASH is part of the larger California Solar Initiative Program. The investor-owned utilities in California outside of the SDG&E territory directly administer MASH rebates for customers in their region.
