Quick answer: No — Maxeon and SunPower are not the same company, but they share a common origin. Maxeon Solar Technologies is the manufacturer that actually makes the cells and panels; it was spun off from SunPower Corporation in August 2020. "SunPower" today is a brand name, now owned by Complete Solaria, after the original SunPower Corporation went bankrupt in 2024. For a cell buyer, the practical point is simple: the famous interdigitated back-contact (IBC) cells were always Maxeon-engineered, so "SunPower cell" and "Maxeon cell" usually mean the same hardware.
TL;DR
- Different companies, shared DNA. SunPower spun off its manufacturing as Maxeon Solar Technologies in August 2020.
- Maxeon = the maker; SunPower = the brand. Maxeon was SunPower's exclusive panel supplier through March 2024.
- Both are now in distress. SunPower Corporation filed Chapter 11 in August 2024 (brand later revived by Complete Solaria); Maxeon filed for court-supervised restructuring in Singapore in April 2026.
- The cells are the same lineage. "SunPower" and "Maxeon" IBC cells (C60/C66) trace to the same technology — which is why, in 2026, "genuine" is about verified provenance, not which logo is printed.
If you've shopped for high-efficiency solar cells, you've seen the same hardware listed under two names — sometimes three. Is "Maxeon" a different product from "SunPower"? Did one buy the other? This guide answers it specifically for people buying cells (not just homeowners comparing rooftop panels): the real relationship, the 2020–2026 timeline, what the names on a listing actually mean, and which one to trust when you need genuine cells.
Is Maxeon the same as SunPower? The short answer
Maxeon is not the same company as SunPower, but it is the company that makes what people think of as "SunPower" technology. Maxeon Solar Technologies is a solar-cell and panel manufacturer; SunPower has, for years, been primarily a brand and residential installer that sold Maxeon-built hardware.
The split is precise and well documented. In August 2020, SunPower Corporation spun off its manufacturing arm into a separate, publicly traded company called Maxeon Solar Technologies. Maxeon kept the factories and the interdigitated back-contact (IBC) cell patents; SunPower Corporation kept the U.S. installation business and the brand. On its own homepage, Maxeon describes itself as having spun off "from SunPower Corporation in 2020" while keeping the same mission.
IBC, the technology at the center of all this, is a monocrystalline cell design in which all the electrical contacts sit on the back of the cell. That is the high-efficiency, all-black "SunPower look" — and after 2020, those cells were Maxeon's to manufacture. If you want the engineering, our guide on SunPower solar cell technology breaks it down.
This shared lineage is also why two related questions keep coming up: "did SunPower become Maxeon?" and "is Maxeon a good brand?" SunPower did not become Maxeon — it created Maxeon in the 2020 spin-off and kept selling its cells. And on the engineering, Maxeon's IBC cells reach module efficiencies above 22% and back panels with warranties up to 40 years, built on more than four decades of back-contact development. So as a brand, Maxeon owns the technology, while "SunPower" now mostly owns the name.
So when someone asks "is Maxeon the same as SunPower," the honest answer is: same heritage and same cell technology, two different corporate entities — and as of 2026, two very different situations.
The timeline: how one company became three
The confusion is easier to clear up once you see the dates. One original company, SunPower Corporation, effectively became three distinct entities over six years.
| Entity (2026) | Role | Status |
|---|---|---|
| Maxeon Solar Technologies | The manufacturer of the cells and panels (Singapore-HQ) | Majority-controlled by TCL Zhonghuan; filed for judicial management in Singapore, April 2026 |
| SunPower Corporation | The original U.S. installer and brand | Filed Chapter 11 bankruptcy, August 2024 |
| "SunPower" (the brand today) | The name, bought and revived by Complete Solaria | A separate company that did not inherit the old warranties |
Here is the sequence, in order:
- August 2020 — SunPower spins off manufacturing into Maxeon Solar Technologies. Maxeon takes the IBC cell technology and factories.
- Through March 2024 — Maxeon remains SunPower's exclusive panel supplier; SunPower-branded panels are Maxeon-made under that partnership.
- August 2024 — SunPower Corporation, the installer, files for Chapter 11 bankruptcy.
- 2025 — The "SunPower" name is acquired and revived by Complete Solaria, which now trades as SunPower — a legally separate company.
- April 2026 — Maxeon, the actual cell maker, files for judicial management (court-supervised restructuring) in Singapore after U.S. Customs detained its modules.
That is why the same IBC hardware shows up under so many labels — and why a 2024-era review and a 2026-era reality can look completely different. For how these cells compare with conventional ones, see our IBC vs standard monocrystalline comparison.
Which name actually made your solar cells?
For cell buyers, the most useful fact is this: the high-efficiency IBC cells branded "SunPower" and the cells branded "Maxeon" come from the same technology lineage. After the 2020 spin-off, Maxeon was the entity manufacturing them, so a "genuine SunPower cell" and a "genuine Maxeon cell" generally describe the same back-contact hardware.
In other words, if you're trying to pin down the SunPower–Maxeon difference at the cell level, there usually isn't one. The more useful question is not "are Maxeon and SunPower cells the same?" but "are the specific cells in front of me genuine, and what generation and grade are they?"
Where it gets confusing is the listing labels. The same family of cells appears under a stack of names and codes, and sellers mix them freely:
| Label you'll see | What it actually means |
|---|---|
| SunPower C60 / C66 | The classic 125 mm IBC monocrystalline cell generations |
| Maxeon Gen III / ME1 | Maxeon's naming for later IBC cell generations and bins |
| "SunPower Maxeon" | Retailer shorthand stacking the brand + the maker — same hardware |
| A300 / E60 | Older SunPower cell/part designations from the same back-contact family |
The takeaway: don't get hung up on whether a listing says "SunPower" or "Maxeon" — both point to the same IBC cell technology. What matters is whether the specific cells are genuine and what generation and grade they are. We decode the part numbers in full in our SunPower C60 / E60J / A300 listing decoder.
Which name do you trust when buying genuine cells in 2026?
In 2026, neither logo alone is a guarantee — because both the brand (SunPower) and the maker (Maxeon) are in financial distress, "genuine" has to be proven by verification, not by the name printed on the cell. This is the single most important shift for buyers.
The stakes are concrete. A 125 mm IBC cell that looks identical under room light can hide microcracks that quietly cut output, and a single mismatched flash-test bin can drag down an entire series string. Genuine Maxeon panels have historically shown warranty return rates near 1 in 20,000 — a quality bar that counterfeits and unsorted B-grade rejects simply do not clear. When you're buying thousands of cells, that gap between "looks like SunPower" and "verified genuine" is the difference between a working array and a field of dead strings.
With Maxeon in court-supervised restructuring and "SunPower" now a revived brand under different ownership, the supply chain is full of orphaned, surplus, and unfortunately counterfeit IBC cells. A seller using either trademark tells you nothing about authenticity on its own. Here is what actually does:
- Confirm the cell type and generation — genuine SunPower/Maxeon C60, C66, or Gen III IBC cells (typically 125 mm), with the rear-contact layout visible.
- Ask for the grade and the grading basis — A-grade vs off-spec, and the criteria behind it. Our cell grades guide explains what each grade really means.
- Require EL (electroluminescence) images to catch microcracks the eye can't see.
- Get flash-test data — power and voltage bins, so your strings are matched.
- Check the quality baseline — genuine cells should meet RoHS, and reputable modules built from them are tested to IEC 61215 (performance) and IEC 61730 / UL (safety), with an IP67/IP68 junction box, UL 2703-listed mounting hardware, and ISO 9001 manufacturing. For off-grid builds, pair them with an MPPT charge controller, not a basic PWM unit, to capture their higher voltage.
