Articles / The Complete List of Solar Bankruptcies and Business Closures
Last Updated:
August 28, 2025
The solar industry experienced
exponential growth over the last decade as costs fell and favorable policies helped drive mass adoption.
However, 2024 has brought immense challenges, with higher interest rates, tighter financing, and adverse policy shifts in key states contributing to over 100 solar bankruptcies based on our industry data, a number unseen before in our almost 20 years in the solar sector.
California was particularly hard hit due to new net metering rules under NEM 3.0 that radically reduced system economics.
These adverse state policy impacts exacerbated financing shifts, triggering plummeting demand and an 80% decrease in rooftop solar installation volume. The California Solar & Storage Association reports that the fallout includes thousands of stalled projects, over
17,000 industry layoffs, and a wave of high-profile bankruptcies.
While stronger players demonstrate some resilience, impacted homeowners and solar employees face prolonged uncertainty. The outright collapse of many once fast-growing solar firms provides a sobering case study on the potential unintended consequences of incentive transitions.

Major Project Cancellations and Bankruptcies
Recent cancellations are primarily tied to federal policy changes and economic factors like supply chain issues and higher interest rates.
Project Cancellations and Pauses (Offshore)
- Revolution Wind (Rhode Island/Connecticut): Construction on this nearly complete 704 MW project was abruptly halted by a federal stop-work order in August 2025, citing national security concerns. A federal judge has since lifted the halt, allowing the project to resume.
- Maryland Offshore Wind Project (Maryland): The federal government has moved to cancel the permit for this project, leading developer US Wind to state it faces bankruptcy if the cancellation is finalized. Federal funding was also rescinded.
- Ocean Wind I and II (New Jersey): Developer Ørsted canceled these projects due to economic challenges, including supply chain problems and rising costs.
- Empire Wind 1 & 2 (New York): The Empire Wind 2 project was scrapped by developers Equinor and BP, and Empire Wind 1 also faced a federal halt, which was later resolved.
- Funding Cuts Across States: The Department of Transportation canceled $679 million in funding for a dozen offshore wind projects and port development in 11 states, including significant amounts for California, Maryland, Massachusetts, and New York.
Project Cancellations (Onshore)
- Idaho Wind Farm (Idaho): A large, 231-turbine land-based project on federal land in southern Idaho was canceled by the Trump administration.
Bankruptcies
- US Wind: The developer for the Maryland project has warned it could go bankrupt if its building permits are revoked by the federal government.
- TPI Composites: This manufacturer of wind turbine blades filed for bankruptcy but anticipated no operational impact at its facilities, including one in Newton, Iowa.
- Solar Companies: While not wind-specific, the solar industry has seen numerous bankruptcies recently due to similar economic pressures, including major players like Sunnova and SunPower.
