The US solar market added fewer new installations in 2025 compared to the previous year, according to a study by the Solar Energy ​Industries Association (SEIA) and Wood Mackenzie. This comes after President Donald Trump scrapped subsidies and tax breaks for renewable energy developers. The study found that the solar market installed 43 gigawatts in new capacity last year, compared to nearly 50 GW in 2024. The One Big Beautiful Bill Act has led to an industry-wide disruption, with utility-scale solar installations declining 16% and community solar declining 25% in 2025. The industry is also dealing with tariff pressures and a freeze on approvals for major projects under the current administration, reflecting an energy agenda focused on oil, gas, coal and nuclear. However, solar and energy storage accounted for 79% of the new capacity additions in the first year of the Trump administration, with over two-thirds of installations occurring in states won by him. The report estimates the U.S. will add 490 GW of new solar capacity by 2036, bringing total installed capacity to nearly 770 GW.
