The National Renewable Energy Laboratory estimates a total of 3,253 MW-AC community solar capacity was installed in the U.S. by the end of 2020 -- enough to power 600,000 homes. The cumulative installed capacity of community solar has grown rapidly since 2010, doubling on average year-over-year.

Community solar enabling legislation exists in 21 states and the District of Columbia, either through state-required programs or authorization of pilot programs, according to NREL.
Currently, 72% of cumulative community solar capacity is concentrated in just four states: Minnesota, Florida, Massachusetts, and New York.
Community solar projects allow residents without suitable rooftops for generation to take advantage of the benefits of solar power, improving access to renewable energy for low-income and disadvantaged communities. Community solar project subscribers often receive guaranteed cost savings on their energy bills, too.
The Biden administration believes reaching its community solar target could create $1 billion in energy savings.
