Environment America modeled the viable technical potential for rooftop solar in the United States, finding that it can serve 45% of U.S. electricity demand based on 2022 levels. In 2022, rooftop solar generated about 1.5% of the total electricity consumed.
Over 3.9 million American households have opted to move forward with rooftop solar.
The data used to generate this logic is based on research by the National Renewable Energy Laboratory, and US Department of Energy group.
