The US installed 43GW of new solar capacity in 2025, marking the fifth consecutive year that solar was the largest source of new power added to the grid.
The Solar Energy Industries Association and Wood Mackenzie said solar and energy storage accounted for 79% of all new capacity installed during the first year of the Trump Administration.
The organisations added the figures were published in the U.S. Solar Market Insight 2025 Year in Review report.
Texas led the country with 11GW of new solar installations during the year.
A total of 11 states set new annual installation records in 2025, while 12 states added more than 1GW of new solar capacity.
Indiana installed nearly 3GW of solar capacity in 2025, up from 1.6GW in 2024.
The report forecasts the US will add 490GW of new solar capacity by 2036, bringing cumulative installed capacity to nearly 770GW.
“Solar and storage continue to dominate new capacity additions to the grid despite policy headwinds,” said Darren Van’t Hof, interim president and chief executive of the Solar Energy Industries Association.
“American households and businesses of all sizes are demanding solar + storage because they deliver fast, affordable power to help meet rapidly rising demand.”
“It’s clear that solar will continue to be the dominant source of new power capacity in the United States, even as gas generation continues to grow,” stated Michelle Davis, head of solar at Wood Mackenzie and lead author of the report.
“Strong demand growth combined with escalating costs of new gas plants will allow solar to remain competitive, even without tax credits.”
