The Washington, D.C.-based solar industry trade association, Solar Energy Industries Association (SEIA), and the UK-based energy consulting group Wood Mackenzie recorded the fall in US solar capacities. US had installed 7.5 GW DC of solar capacity in Q2 2025, down 24% from Q2 2024 and down 28% from Q1 2025. According to SEIA and Wood Mackenzie, solar remained 56% of new generation for the first half of 2025 at 18 GW, with solar and storage combined representing 82% of new capacity additions.  Texas dominated installations with 3.8 GW, followed by California, Indiana, and Arizona, while residential solar was at 1,064 MW DC, an annual decrease of 9%. Commercial capacity increased 27% to 585 MW DC, primarily driven by California's NEM 2.0 pipeline, while utility-scale projects decreased 28% to 5.7 GW DC. Module manufacturing grew by 4.3 GW, taking national capacity to 55.4 GW, but no upstream supply was booked. Projections from 2025 - 2030 were lowered by 4 to 18 percent because of the policy reforms under OBBBA.
