SOMAH helps deliver financial and environmental benefits to your tenants

The Solar on Multifamily Affordable Housing (SOMAH) program provides financial incentives to substantially offset the cost of a solar PV system for your multifamily building. Designed to maximize community benefits, the program requires that the majority of the system directly powers tenant meters, but also provides incentives for common area loads. More than 3,500 properties across the state encompassing nearly 255,000 individual households qualify for incentives under the program.

Helps save on energy costs

Solar PV can reduce and stabilize energy costs for your multifamily building. The SOMAH program provides incentives to substantially reduce the cost of an installation and includes a suite of no-cost technical assistance services to make the process of going solar easier for you.

Provides financial benefits to your tenants

Solar PV systems installed through the SOMAH program must allocate a minimum of 51% of the energy produced to tenant meters through virtual net energy metering (VNEM). Tenants will receive credits on their electricity bills that will help them live more affordably.

Supports economic growth

With a target of 300 megawatts (MW) of solar PV installed by 2030, the SOMAH program will boost the local solar economy, and grow the job market. In addition, the program’s job training requirements will create career development opportunities for your tenants and community.

Supports a healthy California

California has an ambitious goal of 100% carbon-free energy by 2045. The SOMAH program will help you and your community reduce air pollution and be a part of the clean energy transition.

The SOMAH program provides fixed, upfront, capacity-based incentives for qualifying solar photovoltaic (PV) systems. The incentive is paid based on verified solar energy system characteristics such as location, system size, shading and orientation. The amount of the incentive depends on the size of the installed system, the energy percentage split between tenant and common area serving-load and the other funding resources that the project may leverage, such as the federal investment tax credit (ITC) and low-income housing tax credits (LIHTC).

Costs to consider

The SOMAH program substantially reduces the cost of going solar, but there are still some costs to consider, including the application deposit for projects 10kW or larger, staff time and gap financing.

The SOMAH program provides a suite of no-cost technical assistance and other services to make going solar easier for you. Services include:

  • Upfront technical assistance (TA) to help you evaluate the benefits of solar for your property and get started on the process
  • Ongoing (standard) technical assistance to support you throughout the application and installation process
  • Tenant education resources and a hotline to help your tenants understand the project and its impact on their energy bills

The SOMAH program provides an eligible contractor database to help you locate a qualified, program-approved contractor. To facilitate your selection, we’ve created an online contractor bidding tool you can use to obtain competitive quotes from eligible local contractors. Property owners participating in upfront technical assistance are required to obtain at least three bids. Technical assistance in evaluating bids is available to all SOMAH participants.

The SOMAH program was designed to maximize benefits to affordable housing residents. Participating properties are required to share important informational materials with tenants to ensure they understand the project and get full benefits from it. Required materials include:

  • What to expect with solar
  • How to understand your new utility bill
  • How best to maximize your energy savings

These materials, along with other educational resources and tips for tenant engagement, are available in the tenant engagement toolkit.
