SunPower is back. Here's what happened—and what it means for your system

When SunPower Corporation filed for Chapter 11 bankruptcy in August 2024, it sent shockwaves through the solar industry. Since then, the dust has largely settled—but the story kept evolving.

Complete Solaria purchased key SunPower assets in September 2024, including the Blue Raven Solar business, its New Homes division, and its dealer network. In April 2025, Complete Solaria rebranded as SunPower and reclaimed the SPWR ticker on Nasdaq. In October 2025, the company formally changed its legal name to SunPower Inc. Then, in September 2025, SunPower Inc. acquired Sunder Energy, a veteran-owned residential solar company, expanding its installation footprint from 22 to 45 states.

To be clear: SunPower Inc. (Nasdaq: SPWR) is an active, publicly traded company. It is not the same legal entity as the SunPower Corporation that filed for bankruptcy, but it operates under the same name, same ticker, and carries on the same mission.

SunPower, which started as a pioneering manufacturer of high-performance solar panels and grew into one of the nation’s top solar companies, filed for Chapter 11 bankruptcy protection on August 5, 2024.

The company had been struggling for some time. Despite being one of the nation's largest solar companies, SunPower lost $200 million in 2023 as operating expenses doubled. A major policy change in California—the country's largest rooftop solar market—dampened demand, and rising interest rates made financing harder for customers across the country. Then came the accounting errors, Ernst & Young's departure as the company's auditor, and, in August 2024, an official bankruptcy filing.

On August 16, 2024, Nasdaq delisted SunPower Corporation from its exchange for failing to comply with listing rules and file periodic financial reports.

EnergySage's Erik Holvik put it plainly at the time: "SunPower was trying to do everything—from manufacturing to sales to installations to lease and service agreements. It worked when demand was at an all-time high and doubling year over year, but timing matters, as does having a robust strategy capable of withstanding the highs and lows in the marketplace."

The SunPower operating today—SunPower Inc., trading on Nasdaq as SPWR—is a different legal entity from the SunPower Corporation that went bankrupt. Here's the short version of how we got here:

• September 30, 2024: Complete Solaria completed its acquisition of SunPower's Blue Raven Solar business, New Homes division, and dealer network for $45 million.

• April 21, 2025: Complete Solaria announced its rebrand as SunPower, with the SPWR ticker taking effect April 22, 2025.

• October 2025: The company formally changed its legal name from Complete Solaria to SunPower Inc.

• September 24, 2025: SunPower Inc. acquired Sunder Energy, a veteran-owned residential solar company based in Utah, expanding its national installation footprint significantly.

Today, SunPower Inc. operates primarily through Blue Raven Solar. The company reported its first profitable quarter in four years in Q1 2025.

What about the SPWR stock ticker?

This is worth addressing directly, because it's caused some confusion. When SunPower Corporation was delisted from Nasdaq in August 2024, the SPWR ticker went dark. But when Complete Solaria rebranded as SunPower in April 2025, it reclaimed the SPWR ticker on Nasdaq. SunPower Inc. (Nasdaq: SPWR) is an active, publicly traded company on the Nasdaq Global Market.

If you've seen news suggesting SPWR is delisted or that SunPower stock no longer exists, that information is outdated. The SPWR ticker is live and belongs to SunPower Inc.—a distinct company from the original SunPower Corporation.

If your system was installed by SunPower Corporation (the original company) before September 30, 2024), here's what you need to know. (Note: The situation varies depending on how you paid for your system.)

Review all your contracts and warranties

Your paperwork will tell you who holds your warranty, who owns your system, and what you're entitled to. The more clearly you understand your original agreements, the better equipped you'll be to navigate this transition.

Reach out to your original installer

Your SunPower installer will have the most insight into your specific situation. Ask them about your warranty and how they’re handling SunPower customers.

Check SunPower's warranty and resources page

SunPower Inc. has published detailed guidance for legacy customers. This page outlines what's covered, who to contact by equipment type, and how to submit a service request.

Again, your situation depends on when your system was installed and how you financed it.

If your system was energized after September 30, 2024 by Blue Raven Solar, Complete Solar, or their affiliates, your warranties are still valid. SunPower Inc. teams are available to help troubleshoot and service your system.

If your system was energized on or before September 30, 2024, it's more complicated. SunPower Inc.'s purchase of legacy assets did not include taking on responsibility for solar systems, batteries, or equipment installed before the acquisition date.

• If you purchased your system with cash or a loan, contact your lender for guidance.

• If you have a lease or PPA, reach out to your financier or SunStrong Management at (833) 514-1858.

Your equipment manufacturer's warranties are a separate matter. Those are tied to the equipment itself, not to SunPower as an installer, and most major manufacturers are still honoring them. SunPower Inc.'s warranty resources page includes specific contact information for each equipment manufacturer, including Enphase, Qcells, REC Solar, Fronius, Fimer, and Waaree.

If you own your SunPower system (purchased with cash or a loan): You can contact other licensed solar companies for servicing. You're not locked into SunPower.

If you have a solar lease or PPA: The company that holds your lease or PPA agreement is responsible for maintenance. For legacy SunPower leases and PPAs, that's SunStrong Management. Contact them at (833) 514-1858 or reach out to your financier directly.

SunPower Corporation's collapse was a hard chapter for the solar industry. But the story since then has been one of resilience. SunPower Inc. is back on the market, Blue Raven Solar is operating, and new companies continue to step up for customers.

Solar itself is on solid footing. It remains the fastest-growing source of electricity in the U.S., and for most homeowners, it's still one of the strongest financial investments you can make in your home. EnergySage works with hundreds of vetted installers across the country, and our Energy Advisors are here to help you find the right one—whether you're starting fresh or navigating the aftermath of a company change.
