SunPower Production Guarantee After Bankruptcy: What Owners Can Do

By Olivier Beauchemin · Published June 2026

OwlWatt is independent of SunPower and all solar installers. This guide presents factual information about SunPower's bankruptcy and its implications for homeowners — not legal advice. Consult a bankruptcy attorney for guidance specific to your situation.

The situation in plain terms: SunPower filed for Chapter 11 bankruptcy in August 2024. Production guarantees on purchased systems are almost certainly uncollectible as SunPower no longer operates. SunStrong Capital continues managing the lease portfolio. What you can still do: protect your equipment warranties (those run with the manufacturer), establish independent monitoring, and file a claim in the bankruptcy for the record. This page explains each step.

What Happened to SunPower

SunPower Corporation filed for Chapter 11 bankruptcy protection in August 2024 in the U.S. Bankruptcy Court for the District of Delaware (Case No. 24-11649). The filing came after years of financial difficulty, accelerated by rising interest rates, increased competition, and the broader residential solar industry contraction.

SunPower was once the premium brand in residential solar — their high-efficiency panels and long warranty terms were the reason many homeowners chose them over competitors. The bankruptcy left hundreds of thousands of homeowners without their installer's support.

The Status of Your SunPower Agreement

Production guarantees (purchased systems)

Contractual obligation to SunPower; SunPower no longer operating. File as unsecured claim in bankruptcy. Recovery is uncertain and likely minimal.

⚠️
Leases and PPAs

Transferred to SunStrong Capital. Contact SunStrong at 1-855-478-6786 to verify your specific agreement status and ongoing obligations.

Panel manufacturer warranties

SunPower panels were manufactured under various brands. Maxeon Solar (spun off from SunPower in 2020) handles Maxeon panel warranties separately. Verify your panel brand and contact the manufacturer directly.

Enphase microinverter warranties

If your SunPower system uses Enphase microinverters, the 25-year warranty runs directly with Enphase — unaffected by SunPower's bankruptcy.

Your equipment (purchased systems)

The panels, inverters, and racking belong to you. No creditor can take them. You own the physical asset.

The Critical Problem: No One Is Watching Your System

When SunPower was operating, they monitored your system through their internal tools and had some incentive to catch and fix problems — they had warranty liability and a business reputation to protect. With SunPower gone, that monitoring layer disappeared.

A microinverter that stops working, a communication gateway that goes offline, a panel with a manufacturing defect — these failures can now go undetected for months. Every month of silent underperformance is electricity you're not generating but still paying for through your loan.

The production guarantee you had was supposed to catch this. Now it's gone. Independent monitoring is the replacement.

What to Do Right Now

  1. Secure your monitoring access. Log in to your Enphase Enlighten account directly (not through a SunPower portal). If you don't have direct credentials, contact Enphase to claim your system as the homeowner. See: What to do when your solar installer goes bankrupt.
  2. Verify your panel manufacturer. Check the brand name on your actual panels (not the SunPower brand — look at the panel label). Maxeon Solar handles SunPower Maxeon panel warranties; other panel brands have their own warranty processes.
  3. Register equipment warranties directly. Contact the inverter and panel manufacturers to confirm your warranties are registered in your name, not under SunPower's installer account.
  4. File a proof of claim in the SunPower bankruptcy. Even if recovery is uncertain, preserving your claim position costs little. Search for Case No. 24-11649 on PACER (pacer.gov) and file before the claims deadline.
  5. If you have a lease or PPA, contact SunStrong Capital. Call 1-855-478-6786 and confirm how your specific agreement is being administered.

How to Know If Your System Is Still Performing

The first and most urgent question for orphaned SunPower systems is simple: is the system still working? Open your Enphase Enlighten app on the next sunny day and verify your system is generating kilowatt-hours. If the graph shows flat lines or zeros, something is wrong and you need a service call.

The second question is harder: is your system producing at the level it should? A system that generates some power is not the same as one meeting its design output. Without a weather-adjusted comparison against your system's expected production for your location, you cannot answer this question from Enphase's raw numbers alone.

Common Questions

I have SunPower panels and my monitoring is still showing data. Am I okay?

Active monitoring data means your Enphase system is still communicating — which is the hardware platform, separate from SunPower's software. Your system is likely still producing. The question is whether it's producing enough and whether you have ongoing protection if something fails. Enphase's microinverter warranties are still in force; your SunPower production guarantee is not.

Will SunStrong honor SunPower's production guarantee on my lease?

Contact SunStrong directly at 1-855-478-6786 to ask specifically about production guarantee enforcement on your lease. SunStrong acquired SunPower's lease portfolio and has ongoing obligations to lease customers, but the specific terms of those obligations vary. Get any commitment in writing.

What is the Maxeon Solar warranty situation?

Maxeon Solar Technologies was spun off from SunPower in 2020 as an independent company. Maxeon continues to operate and honors warranties on Maxeon-brand panels (SunPower Performance and Maxeon panels sold after the spin-off). Confirm your panel model and contact Maxeon directly at maxeon.com to verify your warranty status.

I have a SunPower solar loan through Mosaic or Sunlight. Do I still owe it?

Yes. Your loan is with a separate lender, not SunPower. SunPower's bankruptcy does not cancel your loan obligation. See our dedicated guide: Solar installer went bankrupt — do I still owe on my loan?

SunPower Is Gone. Your System Isn't.

OwlWatt provides the independent monitoring that SunPower used to provide — connecting to your Enphase hardware, comparing performance to a weather-adjusted baseline, and alerting you when something is wrong. No installer relationship required.
