Solar on Multifamily Affordable Housing



The SOMAH program provides substantial incentives for solar photovoltaic (PV) systems on multifamily affordable housing, making installation costs more economical for property owners. Participating contractors can bring customers into the SOMAH program, as well as bid on projects that have earmarked SOMAH funding.

As an eligible SOMAH contractor, you benefit from:

  • Incentives that may cover as much as 100% of the total system cost for your customers
  • Access to an online portal to bid on new projects
  • A growing customer base
  • Resources for hiring a skilled workforce through SOMAH’s online job portal

At least 51% of the solar energy system's electric output must directly offset tenant load and be provided to tenants in the form of virtual net energy metering (VNEM).

VNEM is a billing arrangement that allows a single solar PV system to offset both multiple common areas and tenant usage, even if they are on different utility meters. Using this method, each utility account is credited with a portion of the electricity generated by the PV system.

The SOMAH program provides fixed, upfront, capacity-based incentives for qualifying solar photovoltaic (PV) systems.

Waitlist and funding status

Current funding for SOMAH is exhausted in SDG&E, PG&E and SCE territories. Applicants are still encouraged to apply and be placed on a waitlist. Applicants will be notified as their project receives funding and removed from the waitlist.
