US Solar Surges Past 11.7 GW in Strong Q3 Despite Political Challenges

Key Takeaways

The US solar industry installed 11.7 gigawatts (GW) of new capacity in Q3 2025, marking the third-largest quarterly addition in history.
85% of new power added to the grid during the first nine months of the Trump administration came from solar and storage, with 73% of this growth occurring in red states.
Over 73 GW of solar projects are currently stalled in permitting limbo, risking future growth unless federal action is taken.

Record Growth Amid Challenges

The US solar industry has achieved remarkable growth, with 11.7 GW of new solar capacity installed in the third quarter of 2025. This figure not only positions the quarter as the third-largest on record, but also brings total installations for the year to over 30 GW. This expansion takes place against the backdrop of efforts by the Trump administration to hinder clean energy initiatives.

The “US Solar Market Insight Q4 2025” report, published by the Solar Energy Industries Association (SEIA) and Wood Mackenzie, highlights a significant shift in the energy landscape. A striking 85% of new power added to the grid during the first nine months of the Trump era originated from solar and storage sources. Notably, 73% of the new installations were concentrated in red states, with Texas, Indiana, Florida, Arizona, Ohio, Utah, Kentucky, and Arkansas leading the way. Utah’s leap into the top 10 was fueled by two major utility-scale projects exceeding 1 GW.

Despite the record increases, the report raises concerns about future obstacles. Federal regulatory measures, particularly a memo from the Department of the Interior (DOI) in July, have created ambiguity in the permitting process for utility-scale solar and storage projects. This uncertainty has kept Wood Mackenzie’s long-term utility-scale forecast for installations through 2030 largely unchanged since last quarter.

SEIA President and CEO Abigail Ross Hopper emphasized the importance of this quarter’s growth, stating that consumer demand is increasingly met by solar energy solutions. However, she warned that if the administration does not amend its stance, the solar industry could face severe constraints, resulting in steeper energy bills for consumers.

In response to rising demand, the US has made strides in solar manufacturing, with two new module factories opening this year in Louisiana and South Carolina. Together, these facilities contribute 4.7 GW of new manufacturing capacity, raising the total for 2025 to 17.7 GW. A new wafer facility is set to start operations in Michigan, allowing the US to produce every major component necessary for solar module manufacturing.

According to Michelle Davis, head of solar research at Wood Mackenzie, the expectation is to see 250 GW of solar installations from 2025 to 2030. However, she also noted that the potential for the solar industry is even greater if current regulatory constraints are alleviated.

Moreover, an analysis by SEIA indicates that more than 73 GW of solar projects are currently blocked in the permitting process, subject to possible politically motivated delays or cancellations.

The outlook for the solar industry remains bright in terms of capacity and demand, but immediate federal action is crucial to ensure the sector can sustain and expand its momentum.
