If you installed a SunPower system a few years ago and you’ve been hearing about the company’s bankruptcy, it’s fair to feel uneasy about what that means for your warranty. The short answer is that it depends heavily on when your system was installed, and untangling that timeline is the first step to knowing where you actually stand.
This guide walks through what happened to SunPower, which parts of your warranty are still valid, and what your options look like if your original installer relationship no longer exists. None of this means your system stopped working, but it does mean the safety net you were promised at installation may look different than you expected.
What Actually Happened to SunPower
The Bankruptcy Timeline
SunPower Corporation filed for Chapter 11 bankruptcy in August 2024 and wound down its operations shortly after. Complete Solaria purchased key assets, including the Blue Raven Solar division, the New Homes division, and the SunPower brand and trademarks, in a deal that closed on September 30, 2024.
At the time, the company also shut down its mySunPower app, web portal, and customer service phone line, leaving many homeowners without a direct way to reach anyone about their system. That gap is what created most of the confusion and anxiety around warranty coverage in the months that followed.
A New Company, Same Name
In April 2025, Complete Solaria rebranded itself as SunPower and reclaimed the SPWR ticker on Nasdaq, formally changing its legal name to SunPower Inc. in October 2025. This is important to understand: SunPower Inc. today is an active, operating, publicly traded company, but it is a separate legal entity from the SunPower Corporation that filed for bankruptcy. If your system was installed and energized after September 30, 2024, it falls under this new company and its warranties are considered valid.
Is Your Specific Warranty Still Covered?
Systems Installed Before October 2024
If your system was energized on or before September 30, 2024, your original installer warranty, the one promised by the old SunPower Corporation, is generally no longer valid. That company no longer exists in its original form, and its obligations were not automatically transferred to the new SunPower Inc.
What’s Still Covered Separately
Manufacturer warranties are a different story. Maxeon, which manufactured many SunPower-branded panels, has confirmed it is honoring panel warranties for legacy systems, and Enphase has done the same for the microinverters used in many installations. These warranties cover the physical equipment even though the installer-level performance and labor warranty from the old company is gone. Our full review of SunPower’s history covers how the company’s structure, including its relationship with Maxeon, worked before the bankruptcy.
It’s worth noting that manufacturer warranties typically cover defective equipment itself, but not always the labor, shipping, or truck-roll costs that come with an actual repair. That distinction matters, since a homeowner might technically have a covered panel but still face a real out-of-pocket bill to get someone onto the roof to replace it.
Lease and PPA Customers
If you have a legacy SunPower lease or power purchase agreement rather than owning your system outright, your servicing arrangement may now run through SunStrong Management or another financier that took over those contracts. Billing and basic system monitoring often continue uninterrupted, but response times for repairs can be slower than what the original company promised.
If you’re unsure who currently holds your lease, checking your most recent billing statement is usually the fastest way to identify the servicing company, since financing arrangements are frequently transferred without much homeowner-facing communication.
What to Do If Your Warranty Is in Question
Gather Your Documentation
Start by pulling together your original contract, any warranty paperwork, and records of your equipment brands, especially the panel and inverter manufacturer. If you can’t locate your contract, your local building permit office typically has a record of what equipment was installed.
Register With the Manufacturer Directly
Contacting Maxeon or Enphase directly to confirm your equipment’s warranty status is worth doing even if you haven’t had any issues yet, since some manufacturers required registration by specific deadlines to preserve legacy warranty coverage. Getting this confirmed now saves time if you ever do need a repair.
Consider Whether an Upgrade Makes More Sense
For some homeowners, especially those whose systems are aging or underperforming, SunPower system expansion or upgrade options can be worth exploring instead of waiting on a warranty claim through an uncertain support chain. This is also a reasonable moment to check how California’s NEM 3.0 rules affect what a new or expanded system would actually save you today.
Why Some Homeowners Are Choosing a Fresh Start
The Case for Switching Providers
If your original installer no longer exists and your equipment is aging, sticking with a fragmented support chain isn’t the only option. A growing number of legacy SunPower owners are choosing to work with a new, actively operating installer instead of navigating manufacturer warranty claims on their own every time an issue comes up.
This is especially true for systems installed in the early to mid 2010s, where panel efficiency has since improved significantly and a decade of wear may already be affecting output. Rather than layering a repair on top of an aging system with uncertain support, a full replacement with a current warranty attached often ends up being the more predictable path forward.
What a New System Costs Today
Understanding how much a new solar system costs gives you a baseline for comparing a full replacement against the ongoing uncertainty of maintaining a legacy system with a fractured warranty picture. In many cases, especially for systems already a decade or more old, how much you could save switching providers outweighs the cost of starting fresh with modern, more efficient panels.
Financing a Transition
If a full replacement feels like a big step, flexible financing options can spread the cost out in a way that’s comparable to what many homeowners were already paying toward a lease or loan on their original system.
Why Homeowners Trust US Power for a Fresh Start
A Stable, Direct Relationship
US Power works directly with Qcells on factory-direct pricing and stands behind every install with a single point of contact, rather than the fragmented manufacturer-by-manufacturer warranty structure that legacy SunPower owners are now navigating. What other homeowners say reflects the kind of ongoing support that matters most once a company’s own installer network is gone.
Getting Clarity on Your Situation
Whether your SunPower system is still fully covered or you’re dealing with a warranty gap from the 2024 bankruptcy, the first step is simply understanding exactly where you stand. From there, you can decide whether registering your existing equipment, pursuing an upgrade, or starting fresh with a new provider makes the most sense for your home.

Frequently Asked Questions
Is my SunPower warranty still valid after the bankruptcy?
It depends on when your system was installed. Systems energized after September 30, 2024 fall under the new SunPower Inc. and are valid. Systems installed before that date lost their original installer warranty, though manufacturer warranties on panels and inverters may still apply separately.
Who services SunPower panels now?
Panel warranties for many legacy systems are handled directly by Maxeon, the manufacturer, while microinverter warranties often run through Enphase. For anything outside manufacturer coverage, like labor or system-level performance guarantees, legacy owners generally need to find a new local installer.
What happened to SunPower lease and PPA customers?
Many legacy lease and PPA agreements are now serviced through SunStrong Management or another financier that took over those contracts. Billing typically continues, but repair response times can vary.
Is the current SunPower Inc. the same company that went bankrupt?
No. SunPower Inc., rebranded from Complete Solaria in 2025, is a separate legal entity that purchased certain SunPower assets and the brand name. It is an active, operating company distinct from the SunPower Corporation that filed for bankruptcy in 2024.
Should I switch providers if my system is still working fine?
Not necessarily, if your warranty situation is confirmed and your system is performing well. But if you’re facing an issue with no clear support path, or your system is aging and inefficient, switching to a provider with a stable, direct warranty relationship is worth considering.
