While the Trump administration has previously stalled approvals for large-scale onshore wind and solar projects, creating uncertainty for thousands of megawatts of clean power capacity, the US solar industry is currently undergoing a significant boom. This surge in solar power generation comes at a time of increasing electricity demand, with power demand projected to rise by 32% by 2030, partly driven by the expansion of AI. Despite the administrative hurdles, the industry is seeing substantial growth, even in politically conservative areas.
The United States has achieved a major clean energy milestone, with its operating solar capacity nearing 300 GWdc, specifically 299.4 GWdc across over 6.2 million installed systems. This capacity is sufficient to power more than 50 million American households, covering the equivalent electricity needs of over one-third of all US households. The second quarter of 2026 alone saw the deployment of 11.4 GWdc of new generating capacity, marking a 45% increase compared to the same period last year and a 43% rise from the first quarter.
Remarkably, this growth is heavily concentrated in states that supported President Trump in the 2024 election. These states accounted for 71% of the country's solar capacity installed in the first half of 2026 and represent 57% of total cumulative capacity. Eight of the top 10 states for new capacity additions this year were considered 'red states,' driven by rapid project execution in major sunbelt markets. California and Texas lead in cumulative solar capacity, with 56,457 MW and 55,125 MW respectively, followed by Florida with 22,550 MW.
In addition to deployment, the domestic clean energy manufacturing sector has also expanded significantly. Over $18 billion has been invested in US solar factory construction, leading to operational module manufacturing capacity reaching 75.3 GW, with an additional 14.4 GW currently under construction. Solar cell manufacturing infrastructure is also developing, with 10.6 GW of operational capacity and 19.1 GW actively being built. The solar sector now provides nearly 9% of total US electricity generation and employs over 280,000 workers across more than 10,000 businesses nationwide, with private solar investment totaling $69.1 billion in 2025 alone.
Despite the overall industry growth, administrative delays under the Trump administration continue to affect specific projects. At least 35 commercial-scale solar power projects that were under review by the Bureau of Land Management when Trump took office are still awaiting action. This includes major projects in Nevada such as the 700-MW Copper Rays Solar Project, the 400-MW Purple Sage Solar Project, and the 300-MW Bonanza Solar Project. Furthermore, two significant solar projects, the Jove Solar Project in Arizona and the Rough Hat Clark County Solar Project in Nevada, with a combined capacity to power 350,000 homes, have been left in limbo despite receiving records of decision in the final weeks of the Biden administration. These delays have imposed financial strain on renewable energy companies.
