Solar On Multifamily Affordable Housing


CSE is a key partner in administering California's Solar on Multifamily Affordable Housing (SOMAH) Program designed to benefit low-income and disadvantaged communities by incentivizing solar electric power.

The largest investment of its kind in the nation, SOMAH's goal is to assure equal access to solar and help reduce energy bills primarily for tenants. The California Public Utilities Commission will provide up to $100 million annually for 10 years under SOMAH to fund 300 megawatts of solar by 2030.

The program's unique, community-based approach ensures long-term, direct economic benefits for low-income households, helps catalyze the market for solar on general market multifamily housing and creates local jobs.

The program includes comprehensive technical assistance for property owners, tenant education and local hiring requirements for contractors.

“We’re proud to partner with CSE to bring clean power and energy savings to residents of multifamily affordable housing in California. CSE knows how to connect the dots to ensure engagement and outreach to diverse stakeholders and expand access to sustainable solutions,” Blanca E. de la Cruz, Sustainable Housing Program Director, California Housing Partnership
