The US solar industry has reached a significant milestone, surpassing 6 million cumulative installations nationwide. However, the sector is grappling with a complex landscape of regulatory and trade policy uncertainties that could impact its future growth. Despite these challenges, solar and energy storage technologies have emerged as the dominant sources of new power capacity in the United States.
In the first quarter of 2026, the US added 7.8 gigawatts (GW) of new solar capacity, marking a notable decline from previous periods but still representing a substantial contribution to the nation’s energy mix. This growth has been driven by a combination of factors, including the need for energy security amidst global supply disruptions and the increasing demand for renewable energy sources.
Record Installations and Market Segmentation
The residential sector saw a 6% year-over-year increase in solar capacity installations, reaching 1,179 megawatts direct current (MWdc). However, this growth was offset by declines in the commercial and community solar segments, which saw decreases of 4% and 4% year-over-year, respectively. The utility-scale segment, which accounted for the largest share of new installations, experienced a 34% year-over-year decline.
Despite these fluctuations, solar and battery storage together accounted for an impressive 91% of all new electricity-generating capacity added in Q1 2026. This dominance underscores the critical role that these technologies play in expanding the US grid’s capacity and ensuring energy security.
Regulatory and Trade Policy Challenges
The solar industry is currently navigating a complex regulatory environment, with uncertainties around foreign entity of concern (FEOC) requirements and ongoing trade cases. These factors have created a challenging landscape for solar manufacturing, with several new cell and wafer facilities in development but facing significant hurdles.
In addition to regulatory challenges, the industry is also grappling with the expiration of the Section 25D tax credit at the end of 2026. This credit has been a key driver of growth in the residential solar market, and its expiration is expected to result in a 21% decline in the sector in 2026. However, forecasts indicate that the residential market will recover in, supported by third-party ownership models and rising retail electricity rates.
Utility-Scale Solar and Energy Security
The utility-scale segment has been a bright spot in the solar industry, with contracts for utility-scale solar rising 15% year over year. This growth has been fueled by tech companies securing power to meet the increasing electricity demand driven by artificial intelligence (AI) and other technologies. The report’s industry-wide forecast has been revised upward to reflect this surge in demand.
Amid rising geopolitical instability, solar and storage technologies are strengthening American energy security. These technologies can be deployed quickly and operate without exposure to fuel price volatility, making them an attractive option for utilities, homeowners, and businesses seeking energy security.
State-Level Developments and Future Outlook
At the state level, Texas continued its dominance as the fastest-growing solar market, with Ohio surging into the top three states for deployment this quarter. Michigan, Oregon, and Mississippi also notched notable quarters, contributing to the
Looking ahead, the outlook for the solar industry from 2026 to 2031 has changed minimally, with an expected increase of 1.4% in total capacity. This stability reflects a market with genuine structural constraints, including interconnection queues, permitting bottlenecks, and ongoing trade uncertainty. Addressing these limitations will be essential to meeting both decarbonization targets and rapidly growing US power demand.
