1. SunPower has meant three different companies

The company answering the phone today is not the company that signed your contract. That single fact explains almost every dead end SunPower customers hit.
The nameWhat it actually isWhat it owes you
SunPower Corporation
Signed your contract
Installed residential systems and ran the monitoring. Filed Chapter 11 in August 2024. The workmanship warranty
Now a claim against the estate
Maxeon
Makes your panels
Spun off as an independent panel manufacturer in 2020. Was not part of the bankruptcy. Your panel warranty
Intact and claimable
Complete Solaria
Uses the name today
Bought assets out of the bankruptcy estate in late 2024, including the dealer network, the customer service operation and the right to trade as SunPower. Nothing owed to you
Bought the brand, not the liabilities
Why this matters more than it sounds. Calling the company that answers as SunPower today gets you a polite dead end, because it never assumed your installer’s obligations. Your panel warranty, meanwhile, sits with a manufacturer that was never in the bankruptcy at all. Knowing which name owns which promise is what stops you spending a month on the wrong phone call.

2. What happened to SunPower

SunPower Corporation filed Chapter 11 on 8/5/2024.

Complete Solaria acquired substantial assets from the estate in late 2024 — the dealer relationships, the customer service operation, and the right to trade under the SunPower name. It did not assume SunPower Corporation’s workmanship liabilities. Those became unsecured claims in the Chapter 11 case, where recovery is commonly little or nothing.

In plain terms: the installation labor coverage is gone. Your equipment coverage is not, and for most SunPower systems the equipment is where the value was concentrated.

This is the honest part of an otherwise good picture. SunPower built premium equipment, and the panel warranties that came with it are among the strongest in the industry. They survive the bankruptcy untouched, because they were never SunPower Corporation’s promise to begin with.

3. Your coverage today

Workmanship and labor
SunPower Corporation
Commonly 10-25 yrs
Your signed agreement governs
Forfeited in Chapter 11
Not covered
Nobody, as a contractual obligation. Complete Solaria bought the brand and the dealer network, not the liability. We will not send you to a company that has already said it does not owe this.
Solar panel modules
Maxeon — a separate company
Typically 25-yr product and performance
6 yrs left of 12
19 yrs performance
Claimable
Unaffected by the bankruptcy. Maxeon was spun off in 2020 and was never part of the Chapter 11 case. This is the strongest coverage you have.
Microinverters
Your inverter manufacturer
25-yr product
19 yrs left of 25
Claimable
Manufacturer obligation, unaffected. Replacement units shipped free on a valid claim.
Battery, if fitted
Your battery manufacturer
Commonly 10 yrs, plus a throughput limit
4 yrs left of 10
Check the term
Battery warranties run on energy throughput as well as years, so the clock runs twice. Yours is the shortest term in the system and the first to expire.
Monitoring and alerts
Your monitoring platform
Platform survives
No fixed term
Action needed
SunPower ran the monitoring, and the platform did not die with the company. Your account exists; ownership rights on it likely do not sit with you.
Production drops, we alert you.

You lost one of five, and it is the installer’s own. The four that survive are manufacturer promises that were never SunPower Corporation’s to break.

4. Is your system actually producing?

SunPower ran your monitoring, so this is the coverage most likely to have quietly stopped working. Here is the difference it makes.

5. What can go wrong, and what to do about it

1

Production and monitoring

Problem
  1. You cannot see your production data
  2. The SunPower app stopped working or changed hands
  3. You get an error saying you do not own any system
None of these are your fault.
Solution
  1. Take ownership of the monitoring account in your own name
  2. We request owner access on your behalf when the installer cannot
  3. We watch it from then on and tell you when something drops
2

Panels

Problem
  1. You do not know what each panel is producing
  2. Overall production is low and you cannot say why
  3. You assume the panel warranty died with SunPower — it did not
Solution
  1. Connect your system so output is visible panel by panel
  2. Claim against the panel manufacturer, not the installer
  3. We tell you which entity to name and what they will ask for
3

Lease or power purchase agreement

Problem
  1. You are not sure whether you own the system or lease it
  2. Nobody has told you who services your agreement now
  3. You are still paying somebody every month
Solution
  1. We identify who took over servicing your agreement
  2. We tell you what they are still obligated to do
  3. The route differs entirely from the owned route — we give you yours
4

Workmanship

Problem
  1. SunPower Corporation is in liquidation
  2. The company using the name today does not owe you this
  3. You are worried about a high service bill
Solution
  1. Connect first, so you know whether you have a real problem before paying anyone to look
  2. Solar insurance exists, and most homeowners have never been told
  3. We match you to a vetted servicer rather than whoever answers an ad

6. Who to contact, and for what

Two verified channels, and neither is a warranty desk

We confirmed two working SunPower-related channels on 8/17/2026. Being straight with you about what they are: neither one honors a workmanship warranty. One serves lease and power purchase agreement accounts only. The other is a list of companies that will repair your system for money.

Which applies to you depends entirely on whether you own the system, and that is the fork this whole kit turns on. One of these channels states in writing that it cannot help owners.

The servicing company that took over the legacy SunPower lease and power purchase agreement fleet, its intake form, and the exact option to select so your request is routed rather than bounced.

The published list of independent service companies covering eighteen states, and how to read it for yours.

What each channel will and will not do, so you do not open with the wrong ask.

In your kit
The channel that matches how you actually hold your system — owned, leased or power purchase agreement (PPA) — with the intake route and the wording that gets it accepted.

7. Your claim letter, ready to send

Re: Module warranty claim — array installed 3/4/2021
To whom it may concern,
I am the owner of the property at 100 Example Street, Springfield. A solar array of 18 modules was installed at this property on 3/4/2021 by SunPower Corporation, which filed for Chapter 11 bankruptcy protection in August 2024. I am writing to you as the manufacturer of the modules, which I understand was a separate company at the time of manufacture and was not party to those proceedings.

I am claiming under the limited product warranty issued with these modules. On the date of this letter that term has nineteen years remaining.

The fault is as follows. The affected module serial numbers are listed below, and the attached production record shows monthly output against expected output, establishing when the shortfall began.

I am not able to obtain installer certification of this claim, as SunPower Corporation is in liquidation and cannot provide it. I ask that this not be treated as a bar to the claim.

Please confirm receipt in writing within thirty days with a claim reference number.

In your kit
The paragraphs that do the work — including the one that pre-empts the objection manufacturers raise most often on systems whose installer has closed, that the installer must certify the claim.
Yours truly,

8. What we checked, and when

  • SunPower Corporation Chapter 11 filing, 8/5/2024 · court record
  • Maxeon spin-off from SunPower Corporation, 2020 · company filings
  • Complete Solaria asset acquisition from the estate, late 2024 · transaction record
  • Lease and PPA servicing channel · confirmed responding 8/17/2026
  • Independent service company list, 18 states · confirmed 8/17/2026
Research rots, so we date it. This SunPower research is next scheduled for recheck on 11/17/2026. The estate is still administering claims, and the servicing arrangements for leased systems have changed hands once already.
