Washington, D.C.-based national trade group Solar Energy Industries Association (SEIA) has reported that the US solar industry installed 11.7 GW of new capacity in Q3 2025. This installation has pushed total annual additions beyond 30 GW, marking the industry’s third-largest quarter on record. According to SEIA and Edinburgh-headquartered data and analytics provider Wood Mackenzie, 73% of this year’s solar capacity was built in Trump-won states. These states have included major solar markets such as Texas, Indiana and Florida, which were highlighted for strong growth. The report has also noted that federal permitting and political roadblocks are threatening 73 GW of planned utility-scale projects. SEIA has said that, despite these headwinds, long-term utility-scale deployment forecasts were largely unchanged through 2030. Earlier this year, SEIA and Wood Mackenzie have reported a solar market decline in the US during Q3 2025.
