Single Family Affordable Solar Housing (SASH)

The CSI Single-family Affordable Solar Housing (SASH) Program provides fully subsidized 1 kW systems to very low-income households, and highly subsidized systems to other low-income households. GRID Alternatives, a non-profit solar organization, manages the $108 million SASH Program overseen by the CPUC.

SASH Eligibility

To qualify for the SASH Program, applicants must meet the following minimum requirements:

  1. Must be a customer and in the service territory of PG&E, SCE, or SDG&E.
    (The project's site must be within the service territory of, and receive electric service from, PG&E, SCE, or SDG&E.)
  2. The residence must be occupied by the homeowner/applicant.
  3. The household's total income must be 80% of the Area Median Income (AMI) or less based on the most recent available income tax return.
    (Area Median Income is subject to annual changes based upon Housing and Urban Development's income guidelines.)
  4. The residence must be California Public Utilities Code (P.U.) 2852-compliant.

A fully subsidized 1 kW system is available to households that meet the legal definition of "very low-income" defined as 50% or below the area median income.

Eligibility for a highly subsidized solar system is determined by the applicant's Federal Income Tax liability and eligibility for the California Alternative Rates for Energy (CARE) Program. Lump-sum incentives will be provided at the following per-watt rates:
