If you own a SunPower solar system in the Sacramento area, the name on your equipment does not necessarily tell you who is responsible for it today.

SunPower Corporation filed for Chapter 11 bankruptcy in August 2024. Since then, parts of the former company have been sold, transferred, or taken over by other organizations. The SunPower name itself is now being used by a different company.

Your solar system did not suddenly become obsolete because of the bankruptcy. But figuring out who handles monitoring, warranty claims, financing, and repairs can now take a little more work.

What Happened in the SunPower Bankruptcy?

SunPower Corporation filed for bankruptcy on August 5, 2024 and began selling its assets.

Complete Solar purchased several parts of the business, including certain assets associated with SunPower’s New Homes division, Blue Raven Solar, its non-installing dealer network, and the SunPower brand. That transaction closed September 30, 2024.

Complete Solar subsequently began operating under the SunPower name.

This is an important distinction for existing customers: the company currently called SunPower is not simply a continuation of the old SunPower Corporation and did not assume responsibility for every system previously installed by SunPower.

The current SunPower explains the transition in its SunPower bankruptcy and acquisition FAQ.

Who Supports Older SunPower Solar Systems Now?

There isn’t one answer that applies to every SunPower system.

The right place to start depends on how the system was purchased, when it was installed, and what equipment is actually on the property.

SunStrong Management

SunStrong Management has taken over account management for many former SunPower customers, particularly systems associated with leases, loans, and power purchase agreements.

SunStrong also operates SunStrong Connect, which replaced the mySunPower app for approximately 110,000 former SunPower customers.

If your system is now managed by SunStrong, this may be where you handle monitoring, account questions, billing, and certain support issues.

The New SunPower

The current SunPower acquired selected assets from the former company, but it specifically states that its acquisition did not include ownership of solar systems, batteries, leases, or PPAs installed on or before September 30, 2024.

That means seeing the SunPower name on a current website does not automatically mean the new company is responsible for servicing your older system.

Enphase

A large number of SunPower systems use Enphase microinverters, including SunPower-branded AC modules with Enphase electronics.

Enphase has created a support program specifically for legacy SunPower system owners. For compatible systems, Enphase can also replace the SunPower monitoring equipment with an Enphase IQ Gateway so the system can be monitored through the Enphase platform.

Enphase states that it continues to honor applicable warranties for Enphase microinverters used in SunPower systems. More information is available through Enphase’s legacy SunPower system support page.

Maxeon Solar Technologies

SunPower and Maxeon separated into different companies in 2020. Maxeon manufactured many of the premium panels associated with the SunPower name, but that does not mean Maxeon automatically inherited SunPower Corporation’s system warranty obligations.

Maxeon’s current warranty information states that coverage for older SunPower-branded panels is limited and depends on the circumstances of the system and its warranty registration.

What Sacramento SunPower Owners Should Do First

If your SunPower system is working normally and you still have monitoring access, there may be nothing you need to do immediately.

If monitoring has disappeared, production appears low, or you have a failed component, I would avoid replacing equipment until you know exactly what is installed and who may still be responsible for it.

1. Find Your Original Solar Documents

Look for the original contract, proposal, permits, equipment specifications, financing agreement, warranty documents, and any paperwork provided when the home was purchased.

For Sacramento-area homes that came with solar already installed, these documents can be especially valuable. They may identify the installer, system owner, panel model, microinverter type, financing company, and original warranty terms.

2. Determine Whether You Own or Lease the System

This changes who you should contact.

• Lease or PPA: Start with the company currently managing the agreement. For many former SunPower accounts, this may be SunStrong.
• Loan: Check both the loan documents and equipment warranty information.
• Owned outright: You may need to work directly with the equipment manufacturer or an independent solar service provider.

3. Identify the Equipment You Actually Have

SunPower systems installed around Sacramento over the years are not all built the same way.

Depending on the age of the system, you may have Enphase microinverters, older SolarBridge microinverters, a string inverter, SunPower monitoring equipment, Maxeon panels, a SunVault battery, or some combination of those products.

The equipment matters because the manufacturer may still provide support even when the original installer or system provider no longer does.

4. Restore Monitoring if Possible

A solar system can continue producing electricity even when its monitoring system is offline. Unfortunately, that also means a homeowner can go months without realizing that part—or all—of the system has stopped producing.

Former SunPower customers should first determine whether their system can use SunStrong Connect, whether the existing SunPower gateway can be reconnected to the internet, or whether an Enphase monitoring conversion is appropriate.

Do not assume that a blank app means the solar itself has failed.

What If Your SunPower System Is Not Producing?

This is where the bankruptcy becomes more than an administrative inconvenience.

If the original installer is gone and monitoring is unavailable, you may have very little information about what is happening on the roof.

A proper diagnostic should establish basic facts before parts are replaced:

• Is the system actually producing power?
• Is utility voltage reaching the solar equipment?
• Is the problem limited to monitoring or communications?
• Are one or more microinverters or panels offline?
• What equipment is installed?
• Is manufacturer warranty support still available?

This is particularly important with an orphaned solar system. Replacing equipment unnecessarily can cost considerably more than identifying the original hardware and determining whether manufacturer support still exists.

I covered this issue more broadly in Orphaned Solar Systems: What Happens When Your Installer Disappears.

Independent SunPower Diagnostics in Sacramento

The SunPower bankruptcy has created an unusual situation: the equipment on many homes is still perfectly serviceable, but the support structure that originally surrounded it has changed.

For homeowners in Sacramento, Roseville, Rocklin, Folsom, Elk Grove, and surrounding communities, the first goal should usually be to identify what you have and determine what is actually wrong before deciding what needs to be replaced.

If the system has stopped producing, is reporting incorrectly, or no longer has usable monitoring, an independent solar diagnostic and performance evaluation can help separate an equipment failure from a communications problem and document the information needed to pursue manufacturer or third-party support.

The SunPower name may have changed hands. The system on your roof has not. Start there.

Final Thoughts…

One detail worth emphasizing: SunStrong currently says SunStrong Connect replaced mySunPower for 110,000 former SunPower customers, while the new SunPower explicitly says it did not acquire responsibility for systems installed on or before September 30, 2024. Enphase separately offers support and monitoring conversions for compatible legacy SunPower systems.

Also, Maxeon’s present warranty language is narrower than many homeowners may expect: it says it only provides limited coverage for certain legacy SunPower panels installed before August 5, 2024 and self-registered with Maxeon before December 31, 2024. That is why I kept the Maxeon section deliberately cautious rather than implying that the old SunPower panel warranty simply transferred to Maxeon.
