SunPower customers in Illinois: what happened, and who services your system now

What happened

SunPower Corporation filed for Chapter 11 on 5 August 2024 and was delisted on 16 August 2024. Complete Solaria bought the Blue Raven, New Homes and dealer-network businesses for $45 million in a sale that closed on 30 September 2024, and rebranded itself as SunPower in April 2025. The Illinois Power Agency's 2025 Consumer Complaints and Disciplinary Actions report names SunPower Capital Services, LLC, the financing arm rather than the parent, as an out-of-business entity that received complaints in 2025. If your contract was with SunPower Capital Services, that is the entity the state is tracking.

What it means for your warranty

Your workmanship warranty is probably gone. When a company liquidates, its warranties are unsecured liabilities and generally do not survive the bankruptcy.

Your equipment warranty probably survived. Your panels and inverter are covered by the manufacturer, a separate company that still exists. Most major manufacturers are still honouring them. What you lost is the person who diagnoses the fault and files the claim.

Who took over, if anyone

Two different companies, depending on your contract. Complete Solaria bought the Blue Raven, New Homes and dealer-network businesses and now operates as SunPower. Legacy lease and PPA customers were routed to SunStrong Management, reachable on 833-514-1858. If you owned your system outright and bought through a dealer, neither may hold your workmanship warranty, and that is the case to check first.

What you can still do

The state's Solar Restitution Program. The Illinois Power Agency's Solar Restitution Program pays up to $30,000 on a project of 25 kW or less and up to $50,000 on a larger one, to customers harmed by an Illinois Shines Approved Vendor or Designee. By June 2026 it had paid about $473,000 to 170 customers. The program decides eligibility, not us, and most affected homeowners have never heard of it.

Manufacturer warranty claims. Your modules and inverter carry their own warranties from the manufacturer, and those companies are still trading. Find the model and serial numbers on the inverter label and in your closing paperwork. A claim needs a diagnosis first, and the manufacturer will usually supply the replacement part and leave the labour to you.

Monitoring access. If your installer set up the monitoring account, get it into your own name now, while the manufacturer's support desk can still verify you as the owner. Enphase, SolarEdge, Fronius and SMA each have a process for handing a system to the homeowner. Without it, nobody can see what the system is doing.

Work out which SunPower entity your paperwork names. A lease or PPA goes to SunStrong Management. A dealer-installed cash or loan purchase most likely has no successor for workmanship, and the manufacturer warranty on the modules and inverter becomes your main route.

Nothing on this page is legal advice. A bankruptcy has deadlines, and a lawyer or the case trustee's site is the place to confirm them.
