Multifamily Affordable Solar Housing (MASH)
Affordable housing customers in California now have clean solar energy with the California Solar Initiative's Multi-family Affordable Housing Program (MASH).
Building owners can install solar PV systems to offset energy used in their building’s common areas, and receive higher rebates for the energy they share with tenants.
| M A S H Incentive Rates ($/Watt) | |
| Track A: PV System Offsetting Common Area Load |
Track B: PV System Offsetting Tenant Load |
| $1.80 | $2.90 |
For more information on how this works, please see the Virtual Net Metering page.
Program Goals
- Stimulate adoption of solar power in the affordable housing sector.
- Improve energy utilization and overall quality of affordable housing through application of solar and energy efficiency technologies.
- Decrease electricity use and costs without increasing monthly household expenses for affordable housing building occupants.
- Increase awareness and appreciation of the benefits of solar among affordable housing occupants and developers.
Please note, due to popular demand the MASH incentive budgets are fully spent for PG&E and CCSE service territories and each is compiling a waitlist to serve customers when other projects drop out and money becomes available. SCE has limited funding available and continues to accept applications.
