Yup, US Solar Growth Hurting from Solar Permitting Delays

The growth of solar power in the United States is facing significant challenges due to delays in the permitting process, according to the latest US Solar Market Insight report from the Solar Energy Industries Association (SEIA) and Wood Mackenzie. These federal permitting slowdowns have caused a backlog of hundreds of solar and energy storage projects awaiting approval, threatening to stall the expansion of solar capacity despite strong demand. Industry leaders warn that if these delays persist, the anticipated growth in solar installations over the next five years could stagnate, undermining efforts to meet rising power needs with clean energy. Key figures from SEIA and Wood Mackenzie highlight the urgency of reforming the permitting system to avoid jeopardising the solar sector’s momentum. Darren Van’t Hof, SEIA’s interim president and CEO, emphasised that solar and storage accounted for 91% of new power capacity in the first quarter of 2026, reflecting the market’s clear preference for low-cost, reliable clean energy. However, he criticised political and regulatory obstacles that are slowing down solar development, warning that continued gridlock would drive up electricity prices and hamper the only sector actively expanding power generation in the US. The report also sheds light on the political dynamics influencing the permitting delays, suggesting that entrenched fossil fuel interests and their financial influence on political campaigns are contributing to the obstruction of solar progress. With 457 solar and storage projects currently stuck in permitting limbo, these delays not only threaten the projects themselves but also the broader transition to a cleaner energy system. Michelle Davis, head of solar at Wood Mackenzie, noted that while utilities are increasingly planning for solar in their resource strategies, the permitting bottlenecks remain a significant near-term barrier. The implications of these findings are concerning for the future of renewable energy in the US. Despite solar power becoming increasingly affordable and technologically mature, the sector faces a precarious period marked by administrative hurdles and political resistance. Without swift action to streamline permitting processes, the US risks missing out on critical opportunities to expand clean energy infrastructure and meet growing electricity demand sustainably. The situation underscores the need for policy reforms that prioritise the acceleration of solar deployment to ensure a more resilient and affordable energy future.
