Is SunPower Still in Business in 2026? The Honest Answer

"Is SunPower still in business" is one of the most-searched questions in residential solar right now, and most answers online are either out of date or quietly wrong. The confusion is understandable: the brand "came back" in 2025, the stock ticker never disappeared, and the official website still works. But behind that one name sit three legally separate companies and two distinct corporate failures. This guide untangles them — and explains what each one means if you own a system, depend on a warranty, or source SunPower/Maxeon IBC cells for your own builds.

Three SunPowers, two deaths: clearing up the confusion first

There are three legally distinct entities sharing the "SunPower" name in 2026, and treating them as one company is the single biggest reason people get the answer wrong. Here is how they actually break down:

The key split happened in 2020, when SunPower separated its manufacturing arm into Maxeon Solar Technologies. After that, "SunPower" was the brand and installer, while Maxeon was the company that physically built the cells and panels. Both halves have now failed — but for completely different reasons, on different timelines. If you are here for the cells rather than the brand drama, our SunPower C60 solar cell buying guide covers what is still obtainable today.

What happened to SunPower the installer (the bankruptcy you read about)

The SunPower Corporation that filed for bankruptcy was the installer and dealer business, not the cell factory. On August 5, 2024, SunPower Corp. filed voluntary petitions for Chapter 11 in the U.S. Bankruptcy Court for the District of Delaware. The same day, it signed an asset-purchase agreement naming Complete Solaria as the "stalking horse" buyer for its Blue Raven Solar business, New Homes division, and non-installing dealer network — for roughly $45 million in cash (Financier Worldwide).

The sale closed at the end of September 2024. Then the brand staged a comeback: in April 2025, Complete Solaria rebranded itself as SunPower and reclaimed the SPWR ticker on Nasdaq, and later formally changed its legal name to SunPower Inc. (PV Tech). This is where most people get tripped up. The company trading as "SunPower" today is a new legal entity — it carries the same name, ticker, and mission, but it did not assume the original corporation's debts or, critically, its old warranty obligations on a like-for-like basis. Same logo, different balance sheet, different owner.

What happened to Maxeon — the company that actually made the cells

Maxeon is the half of the story that matters most if you buy or build with SunPower cells, and its situation is more serious than the installer's bankruptcy. Maxeon took SunPower's interdigitated back-contact (IBC) cell technology when it spun off in 2020 and became the manufacturer behind the brand's famous high-efficiency cells. By late 2025, its business had unravelled: revenue cratered from $371 million to about $39 million in a single half-year as its panels were held out of the U.S. market, and its U.S. factory plans were paused (Solar Power World).

Control had already shifted: Maxeon's largest shareholder is China's TCL Zhonghuan, which moved to take a majority stake during the company's financial distress (pv magazine). The practical consequence for buyers is blunt: the classic SunPower/Maxeon IBC cells are no longer in routine new production through the original channel. They have become an orphaned, finite asset — which is exactly why so much surviving stock now trades as surplus. If you are weighing those cells against ordinary panels, our SunPower IBC vs standard monocrystalline comparison breaks down what you actually gain.

Are SunPower panels and cells still available — and what about your warranty?

You can still buy SunPower-branded systems and genuine SunPower/Maxeon cells, but not the way you used to, and your existing warranty is the harder question. The new SunPower Inc. continues to sell and install residential systems, so "SunPower panels" remain available in that retail sense. Warranties are murkier: a product or workmanship warranty issued by the bankrupt SunPower Corporation is a claim against a company that no longer exists, and the new entity is not obligated to honor every legacy claim automatically. Owners should confirm in writing who, if anyone, now stands behind their specific equipment.

For the cells themselves, the supply picture has changed permanently. With Maxeon's manufacturing wound down, the classic C60 and later-generation IBC cells are now sourced primarily as genuine surplus stock — real, factory-made cells from existing inventory rather than fresh production. That is not a downgrade in the cell itself; it is a change in where it comes from and how you verify it. If you need to replace a damaged panel or keep a build running, see where to buy SunPower solar cells in 2026 for the realistic sourcing routes.

If you own — or build with — SunPower IBC cells, here's the realistic path

If you depend on SunPower/Maxeon IBC cells for a product, a repair, or a small-batch build, the workable answer in 2026 is verified genuine surplus, sourced and graded carefully. Because the original supply is gone, the market now mixes high-grade factory stock with reclaimed, off-spec, and re-labeled cells — so verification matters more than ever. Before you commit to any surplus SunPower/Maxeon cells, confirm three things:

• Grade — ask whether they are A-grade cells or rejects/B-grade. Our guide to SunPower cell grades explained shows how to tell the tiers apart.
• Test data — request electroluminescence (EL) imaging and flash-test (I-V) data where the order size justifies it, so you are buying measured performance, not a claim.
• Spec match — confirm the cells can be matched (Imp/Isc) or cut to your panel's exact specification.

One point on language, because it protects you legally and commercially: a legitimate supplier of this stock is not affiliated with, endorsed by, or a successor to SunPower or Maxeon. What honest sellers offer is genuine, legally-sourced, de-branded surplus — not "new factory-direct" or "authorized" cells. As a sourcing partner with direct factory-side QA access, LinkSolar helps OEMs, integrators, and builders source and verify genuine surplus SunPower/Maxeon IBC cells, including grading and custom cut-to-size service for IoT and specialty panels. The brand may be gone; the cells, sourced correctly, are not.

FAQ: SunPower in 2026

What happened to SunPower solar panels?
The original SunPower Corporation (the installer, founded 1985) filed Chapter 11 bankruptcy in August 2024 and sold its assets. A separate company, Complete Solaria, bought the brand and now operates as SunPower Inc. The cell manufacturer, Maxeon, separately collapsed — so the panels you knew are tied to companies that have changed hands or shut down.

Who took over SunPower?
Complete Solaria acquired SunPower's brand, Blue Raven Solar, and dealer network out of bankruptcy in 2024, then renamed itself SunPower Inc. in 2025. It is a different legal entity from the original SunPower Corporation.

What is the new name for SunPower?
The active company is now legally SunPower Inc. (formerly Complete Solaria), trading under the original SPWR ticker on Nasdaq. The cell-making side remains a separate company, Maxeon Solar Technologies.

Are SunPower panels still available?
SunPower-branded residential systems are still sold by the new SunPower Inc. Genuine SunPower/Maxeon IBC cells, however, are now mainly available as verified surplus stock rather than new production, because Maxeon's manufacturing has wound down.

What happens to my warranty if SunPower went out of business?
A warranty from the bankrupt SunPower Corporation is a claim against a company that no longer exists, and the new SunPower Inc. is not automatically obligated to honor every legacy warranty. Confirm in writing who currently backs your specific equipment, and budget for the possibility that the practical remedy is sourcing a matched genuine-surplus replacement.
