Key Findings
- 424,217 home solar systems in the records were installed by 22 companies that have since closed or gone bankrupt. Their owners were left without the installer's workmanship warranty and service.
- SunPower alone accounts for 108,873 of them. Filed for Chapter 11 bankruptcy in August 2024.
- California is the largest market in the records: 586,529 home systems in 2023–2025, with a median price of $4.25/W for owned systems and 34% leased or on a PPA.

Solar Installers That Closed, by Systems on Record
Home systems each company installed, over all years, in the states we cover. Massachusetts is not included, because its latest complete records are too old for us to rank it, so companies active mainly there, such as Next Step Living, show fewer systems than in our list of solar companies that closed. Closures are verified in the press or court filings; companies that were acquired are not counted. Download CSV
Home Solar by State
The latest three complete years of records in each state with at least 1,000 home systems. Price is the median per watt of systems the homeowner bought, before incentives. A dash means the state's records don't report it. Download CSV
