The US solar industry has experienced a remarkable first quarter in 2025, but potential policy changes may threaten its growth. According to the latest US Solar Market Insight report from SEIA and Wood Mackenzie, the industry added **10.8 gigawatts (GW)** of new solar electricity generation in Q1 2025. Notably, solar and storage comprised an impressive **82%** of all new capacity added to the grid. Additionally, US solar manufacturing is thriving, with **8.6 GW** of new module manufacturing capacity introduced during this quarter, marking the third-largest quarterly increase on record. This progress is attributed to the opening or expansion of eight factories located in Texas, Ohio, and Arizona. Furthermore, US solar cell production doubled to **2 GW**, largely due to a new factory launched in South Carolina.
However, this rapid expansion faces significant challenges. New tariffs, along with the “Big, Beautiful Bill” recently passed by the House, threaten to undermine clean energy tax incentives, creating substantial uncertainty in the market. SEIA cautions that if the Senate does not amend the legislation, the fallout could be dire, resulting in factory closures, energy shortages, job losses, and increased electricity bills. Abigail Ross Hopper, president and CEO of SEIA, stated, “Solar and storage continue to dominate America’s energy economy, adding more new capacity to the grid than any technology using increasingly American-made equipment. But our success is at risk.”
According to SEIA, if Congress fails to take corrective action, **330,000 jobs** could vanish, along with **331 planned or operational factories** and **$286 billion** in local investment. Additionally, American consumers could face **$51 billion** in higher power bills. The uncertainty surrounding tariffs is already unsettling the industry. Anti-dumping and countervailing duties (AD/CVD) on solar cells and modules from Southeast Asia, coupled with other tariff adjustments, are contributing to this instability. Proposed alterations to clean energy tax credits would also hinder long-term planning for both manufacturers and developers.
Zoë Gaston, a principal analyst at Wood Mackenzie, noted, “The **10.8 GW** of solar capacity installed in Q1 2025 represents a significant portion of new US electricity generation. However, our analysis indicates that the US solar market has not yet reached its full potential.” This concern is echoed by SEIA and Wood Mackenzie, both of which have downgraded their five-year forecasts for every solar segment except for community solar. They predict a **14%** decline in residential solar compared to earlier projections and a **6%** decrease in utility-scale solar. Should clean energy tax credits be rolled back, this forecast could deteriorate even further.
A significant source of tension arises from political dynamics. Texas led the nation in new solar capacity in Q1 2025, while Florida surpassed California to secure second place. Notably, eight of the top ten states for solar installations during this quarter supported Donald Trump in the 2024 elections. This indicates that the regions most vulnerable if the House bill remains unchanged are represented by Republicans. SEIA warns that a reduction in clean energy tax incentives could lead to a **173 terawatt-hour (TWh)** decline in US energy production, hindering the country’s ability to compete with China in the global AI energy race.
In summary, while the US solar industry is experiencing rapid growth, missteps in policy could abruptly halt progress just when momentum is building.
