The US solar industry just delivered another huge quarter, installing 11.7 gigawatts (GW) of new capacity in Q3 2025. That makes it the third-largest quarter on record and pushes total solar additions this year past 30 GW – despite the Trump administration’s efforts to kneecap clean energy.
According to the new “US Solar Market Insight Q4 2025” report from Solar Energy Industries Association (SEIA) and Wood Mackenzie, 85% of all new power added to the grid during the first nine months of the Trump administration came from solar and storage. And here’s the twist: Most of that growth – 73% – happened in red states.
Eight of the top 10 states for new installations fall into that category, including Texas, Indiana, Florida, Arizona, Ohio, Utah, Kentucky, and Arkansas. Utah jumped into the top 10 this quarter thanks to two big utility-scale projects totaling more than 1 GW.
But the report also flags major uncertainty ahead. Federal actions, including a July memo from the Department of the Interior (DOI), have slowed or stalled the approvals pipeline for utility-scale solar and storage. Without clarity on permitting timelines, Wood Mackenzie’s long-term utility-scale forecast through 2030 remains basically unchanged from last quarter.
“This record-setting quarter for solar deployment shows that the market is continuing to turn to solar to meet rising demand,” said Abigail Ross Hopper, SEIA’s president and CEO. She added that strong growth in red states underscores how decisively the market is shifting toward clean energy. “But unless this administration reverses course, the future of clean, affordable, and reliable solar and storage will be frozen by uncertainty, and Americans will continue to see their energy bills go up.”
Two new solar module factories opened this year in Louisiana and South Carolina, adding a combined 4.7 GW of capacity. That brings the total new US module manufacturing capacity added in 2025 to 17.7 GW. With a new wafer facility coming online in Michigan in Q3, the US can now produce every major component of the solar module supply chain.
“We expect 250 GW of solar to be installed from 2025 to 2030,” said Michelle Davis, head of solar research at Wood Mackenzie and lead author of the report. “But the US solar industry has more potential. With rising power demand across the country, solar could do even more if current constraints were eased.”
SEIA also noted that, following an analysis of EIA data, it found that more than 73 GW of solar projects across the US are stuck in permitting limbo and at risk of politically motivated delays or cancellations.
