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 equity 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 2032.

The program's 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 careers in the solar industry.

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

"I'm most excited about continuing the solar installations across our portfolio and showing our peers in affordable housing how it's easy to do—and that it makes a difference. I definitely recommend the program to every affordable housing provider. It delivers clean energy, not just for residents, but for the whole community.” Laura Hall, CEO President of EAH Housing
