The US installed 43 GW of new solar capacity in 2025, marking the fifth consecutive year that solar has been the largest source of new power added to the grid. According to the "US Solar Market Insight 2025 Year in Review" by SEIA and Wood Mackenzie, solar and energy storage accounted for 79% of all new electricity generation capacity. Notably, over two-thirds of the solar installations were in states won by Donald Trump in the 2024 election.
