Solar PV systems generate clean, low-cost electricity and in many cases can deliver meaningful energy cost savings benefits by reducing electric utility bills. In addition, solar PV systems are able to generate revenue through the monetization of Renewable Energy Certificates.

Battery energy storage systems are also power resources for generating financial benefits. Similar to solar, batteries can lower electric utility bills by reducing a facility’s peak demand, and shifting load to less expensive hours of the day. In addition, batteries can generate revenue by participating in emerging grid services and distributed energy resources programs.

When combined with the proper controls, switching, and load management technologies, solar PV & battery energy storage systems can also operate as a microgrid to provide backup power support for critical loads during power outages such as wildfire related Public Safety Power Shutoff events, heat-wave related rolling blackouts, and unplanned outages.


The Federal Investment Tax Credit (ITC) provides an incentive for both stand-alone solar and solar + battery projects. This incentive currently provides a tax credit of 26% of the project costs. Third-party project owners can claim this benefit and share this value with site hosts through reduced agreement payments. This incentive will soon begin stepping down in value annually at the end of 2022.

California’s Self-Generation Incentive Program (SGIP) is a rebate program that provides incentives for battery energy storage systems (along with other energy technologies). Based on the location of the project and the type of facility where the project will be deployed, SGIP rebates cover between ~30-100% of the cost of the project. Given the rich incentive levels, and substantial battery project demand, funding for this incentive program is expected to be fully subscribed in 2021.
