U.S. Solar Energy Growth and Challenges in 2025

The U.S. solar energy sector is experiencing significant growth, with the Federal Energy Regulatory Commission (FERC) reporting the addition of 16 gigawatts (GW) of solar capacity through July 2025. This figure represents nearly 75% of the total 21.5 GW of new electric generation capacity added nationwide. In contrast, wind energy contributed 3.2 GW, while natural gas added 2.2 GW. The overall energy mix remains dominated by natural gas, which accounts for 42% of the grid, followed by coal at 14.8%, wind at 11.81%, and solar at 11.42%. Projections indicate that solar could surpass coal by 2028, with FERC forecasting a total installed capacity of approximately 250 GW for solar, compared to coal's anticipated 173 GW.

Corporate procurement of renewable energy is a key factor driving this expansion. Over the past decade, corporations have secured over 100 GW of clean energy contracts, representing 41% of all clean energy capacity added to the grid. Major companies like Microsoft are leading this trend, with a record-breaking agreement for over 10.5 GW of renewable energy capacity. This corporate demand not only stabilizes project financing but also enhances the viability of renewable energy projects, particularly through virtual power purchase agreements (VPPAs), which significantly reduce financial distress risks for developers.

Despite the overall growth in solar energy, the community solar market has faced challenges, with installations declining by 36% in the first half of 2025 compared to the previous year. This downturn follows a record-setting 2024 and is attributed to the impacts of the One Big Beautiful Bill Act and related federal policy changes. Analysts predict a national contraction in community solar capacity, with expectations of an average annual decline of 12% through 2030. The report highlights that while customer demand for community solar remains high, structural bottlenecks and policy uncertainties hinder growth.

The rapid expansion of solar energy has exposed vulnerabilities in the supply chain, with over 80% of solar modules manufactured in Asia. This concentration poses risks related to shipping delays and component shortages. Industry leaders emphasize the need for diversification in sourcing to mitigate these risks and ensure a steady supply of solar modules. The U.S. Department of Energy projects that solar could account for up to 40% of the nation's electricity supply by 2035, underscoring the importance of a resilient supply chain to meet ambitious clean energy goals.

Jose Antonio Miranda, CEO of Avangrid, remarked on the importance of projects like the Tower Solar initiative, stating, “Tower Solar will bring much-needed capacity to the regional electric grid, improving the reliability and availability of electricity.” Meanwhile, Caitlin Connelly from Wood Mackenzie noted, “After a record year, the market is adjusting to new policy dynamics and structural bottlenecks,” emphasizing the need for policy stability to support future growth.

While the overall solar capacity is projected to grow, there are conflicting reports regarding the community solar market's future. Some analysts predict a contraction due to policy changes, while others highlight potential growth in emerging markets if legislative support is strengthened.
