CSI Single-Family Affordable Solar Homes (SASH) Program

On January 29, 2015, the CPUC approved a decision to revise SASH’s enrollment eligibility requirements, capacity target, job training requirements, incentive levels, and allow third-party project ownership.

In October 2014, the California Solar Initiative’s Single-family Affordable Solar Homes (SASH) Program issued its Q3 2014 Program Status Report, which provides detailed information on the program's progress in each of the three service territories in California. The program is managed by GRID Alternatives, an Oakland-based non-profit organization.

At the end of Q3 2014, 4,125 PV-systems have been installed and interconnected, 313 projects have been reserved and are awaiting installation or interconnection, and another 303 applications statewide are under review by GRID's construction staff and sub-contracting partners. In total, these projects have or will receive approximately $86 million in incentives and represent 14.3 MW of solar capacity. In addition, the SASH program has helped enroll 4,075 low-income homeowners into the utilities’ Energy Savings Assistance (ESAP) programs, and has trained over 12,900 volunteers.

AB 217 Implementation

Assembly Bill 217 (Bradford, 2013) extended the SASH and MASH programs of the California Solar Initiative with $108 million in new funding, and set several new goals for the programs. To read the Energy Division’s July 2014 staff proposal regarding the implementation of AB 217 at the Commission, please visit this link. For this and all other documents released in the Commission’s R.12-11-005 rulemaking, please visit the R.12-11-005 Docket Card page.


The Energy Division has hired Navigant Consulting, Inc. to perform in-depth evaluations of CSI SASH and MASH program design, delivery, operations, and impact in 2014 and 2015. This new round of program evaluation will build upon the previous SASH and MASH studies completed in 2011, available through the links below. Energy Division staff anticipate the release of three reports by mid-2015: a program administrator and market assessment, a benefit-cost analysis, and a summary of program design recommendations encompassing both programs.

About SASH

The California Solar Initiative (CSI) has a Single-family Affordable Solar Homes (SASH) Program that provides solar incentives on qualifying affordable single-family housing. The goals of the SASH program are to:

  • Decrease electricity usage by solar installation and reduce energy bills without increasing monthly expenses
  • Provide full and partial incentives for solar systems for low-income participants
  • Offer the power of solar and energy efficiency to homeowners
  • Decrease the expense of solar ownership with a higher incentive than the General CSI Program
  • Develop energy solutions that are environmentally and economically sustainable

The SASH program offers fully or highly subsidized solar systems to qualified low-income homeowners.

  • To qualify for a fully subsidized 1 kW system, homeowners must meet the legal definition of "low-income residential housing" in Public Utilities Code 2852. Eligibility is limited to owner-occurpied households that received electric service from the investor-owned utilities (Pacific Gas & Electric, Southern California Edison, and San Diego Gas & Electric) and whose household income is at or below 50 percent of the area median income (AMI).
  • To qualify for a highly subsidized solar system is determined by household income less than 80% AMI, housing stock eligibility, Federal Income Tax liability, and eligibility for the California Alternative Rates for Energy (CARE) Program.

Upfront solar incentives will be provided at the following per-watt rates:

Incentive Rates for Highly Subsidized Systems (shown in $ per watt)
