Research output: NRELTechnical Report


As of May 2022, at least 18 states and Washington, D.C., included caps on their community solar programs. Most of these program caps are capacity-based, meaning that they limit the program size by capacity (i.e., the number of megawatts of energy produced by participating projects). In general, these programs are at the state level and are developed based on legislative mandates. Community solar deployment has been concentrated in a limited number of states. Of the top 10 states with community solar deployment, 5 have program caps and 5 are uncapped. In states with program caps, installed community solar capacity ranges from 7% to 40% of the program cap.
