Is this the SunPower that went bankrupt?
No. SunPower Corporation went bankrupt in August 2024. The SunPower selling solar today is a different company. It bought the name.
For decades, SunPower was one of the best-known names in solar. Then the original company went bankrupt in August 2024. Many homeowners were left asking who would stand behind their panels.
Later that year, Complete Solaria bought the SunPower name and some of its assets. Then it renamed itself SunPower. It is a separate business. It has its own warranty, its own BBB file and its own Texas license. Here is how the two compare:
- Complete Solar starts
The company behind today’s SunPower is founded. It later grows into Complete Solaria.
- The old SunPower goes bankrupt
SunPower Corporation, the famous original, files for bankruptcy.
- A new owner takes the name
Complete Solaria buys the SunPower name and some assets, plus the Blue Raven Solar business, then renames itself SunPower.
- BBB accreditation
The new SunPower’s Utah BBB profile becomes accredited, with an A+ grade.
- Sunder Energy joins
A large solar sales company folds into SunPower, and its website now loads SunPower’s.
The new company explains what it took on in 2024 on its company history page.
Already own a SunPower system? Here’s who to call
The answer depends on two things: when your system went in and who sold it to you. The finder sorts it out in three questions.
Have a SunPower system? Find out who handles it now.
Answer three questions from your contract. We will point you to the right place. It depends on when you bought and from whom.
This points you to the right starting place. Your own contract always decides what’s covered.
Did your system come from the old company? Our guide for old SunPower customers walks you through it. It covers what changed, what still applies and who handles leases now.
Why the new SunPower scores 80
It earned full marks in four of seven areas. The 20 points it missed came from price, a missing certification and no warranty backup.
The new SunPower has no lawsuits, settlements or state actions in the last five years. In 2024, Minnesota issued an order about Blue Raven Solar. That was before SunPower bought Blue Raven. SunPower says it did not take on Blue Raven’s past debts and claims, so we don’t count it.
We use one formula for every company, built from public records only. No company pays us. Ads never change a score.
What the new 10-year warranty covers, and what it replaced
The new SunPower covers its install work for 10 years. That includes keeping the holes in your roof sealed. The old 25-year promise belonged to the bankrupt company.
A workmanship warranty covers the install work. SunPower’s lasts 10 years and covers the spots where the system goes through your roof. SunPower also gives a production guarantee in writing. That is a promise about how much power your system should make. Service help lasts two years.
Watch the numbers in old ads. Older SunPower ads talked about 25 years. That promise came from the company that went bankrupt. It does not cover systems the new SunPower sells.
The top complaint: money people say they’re owed
SunPower’s BBB file shows 553 complaints in three years. In the 30 newest, money problems came up most. Slow replies came next.
We read the 30 newest complaints, from July 16 to September 10, 2026. SunPower answered all 30. Billing, loan and refund problems came up 21 times. Many people said promised loan or rebate checks stopped coming. Others said approved refunds never arrived.
Slow replies came next. Calls and emails went unanswered. Equipment and repair problems followed. Some small inverters stopped reporting. One battery failed after a year. Some repair visits were mised or canceled.
Complaints only lower a score in our formula when the BBB flags a pattern. SunPower’s file has no such flag. Still, if a rep promises you a check or a rebate, get the amount and the date in your contract.
Who will put the panels on your roof?
SunPower’s own installers, it says. Its careers page talks about everyone from the CEO to its installers.
The new SunPower hires full-time installers and crew leads. That fits a company with its own crews, so it gets all 12 points for who installs. Two details are worth a question. It bought Sunder Energy, a big sales company that does not install. And its contact form lists subcontractors as one kind of partner.
None of that means a stranger will do your job. It does mean you should ask. Before you sign, get the name of the crew or company that will install your system. Get its license number too.
How much does SunPower cost?
SunPower does not post prices or loan fees. You only see a number in a quote. That cost it 11 of 15 points for showing its price.
With no posted price, use a yardstick. Two other national companies we review post theirs. Tesla’s Texas price is about $2.67 a watt. Project Solar posts a full price list. Our Tesla price estimator shows what your system size costs at each posted price.
Ask SunPower for a quote with every cost on its own line. That means equipment, labor, permits and any loan fees. Also remember that the 30% federal tax credit for buyers ended on December 31, 2025. SunPower’s current pages say so. That earned it the 4 points for honest tax-credit claims.
20 states, and a Texas license due for renewal
SunPower sells in 20 states. Its Texas license is active, but it is up for renewal at the end of 2026.
Here are the states on its list:
- California
- Colorado
- Idaho
- Illinois
- Indiana
- Kansas
- Kentucky
- Michigan
- Minnesota
- Nevada
- North Carolina
- Ohio
- Oregon
- Pennsylvania
- South Carolina
- Texas
- Utah
- Virginia
- Washington
- Wisconsin
In Texas, the license is held by Complete Solar Inc, the company’s older name. It is EC-35647, active through December 30, 2026. That keeps SunPower in our Texas ranking, 4th of 20. We will check the license again after that date. In any state, look the installer up on your state licensing board’s website before you sign.
Four questions for a SunPower rep
A new owner and a famous old name make it easy to assume things. These four questions take the guessing out.
- Which company am I signing with? The contract should name SunPower Inc. Make sure the warranty comes from the same company.
- Who will install my system? Get the crew or company name and its license number in writing.
- What does the production guarantee promise? Ask for the yearly amount and what SunPower pays if your system falls short.
- Are any checks or rebates promised to me? Put the amount, who pays it and the date in the contract.

SunPower doesn’t pay us. We earn nothing if you buy from it. Records change, so check the company name on your contract and its license before you sign.
