US Solar Installations Decline to 43 Gigawatts in 2025

The solar market in the United States experienced a slowdown in new installations during 2025, according to a report released on Tuesday. Data from the Solar Energy Industries Association (SEIA) and Wood Mackenzie shows that the industry added 43 gigawatts (GW) of new capacity last year, a decrease from the nearly 50 GW installed in 2024. This cooling momentum follows the implementation of the One Big Beautiful Bill Act, which scrapped various subsidies and tax breaks for renewable energy developers.

Utility-scale solar installations dropped by 16% while community solar projects saw a 25% decline in 2025. The industry is currently contending with increased tariff pressures and a freeze on federal approvals for major projects. This shift reflects a broader change in the national energy agenda, which has pivoted toward oil, gas, coal, and nuclear power, marking a departure from previous green energy policies.
