U.S. Solar Market Insight


Updated December 13, 2022

The U.S. installed 4.6 gigawatts (GWdc) of solar PV capacity in Q3 2022 to reach 135.7 GWdc of total installed capacity, enough to power 24 million American homes. Solar has accounted for 45% of all new electricity-generating capacity added in the U.S. through the first three quarters of the year. Residential solar had another record quarter with 1.57 GWdc installed. Utility-scale solar installations reached 2.5 GWdc, a 36% decrease over the same quarter last year, as the industry continued to weather supply chain challenges and trade disruptions. Despite these challenges, the passage of the Inflation Reduction Act (IRA) has created significant upside to the long-term solar forecasts, with 21% average annual growth forecasted for 2023 - 2027.
