SunPower review: same name, different company. Here’s what changed.

The SunPower that went bankrupt in 2024 is gone. Another company bought the name. It now sells solar as SunPower. We scored the new company on its own records. We also sorted out what this means if you already own a SunPower system.

Short answer

Mostly yes, if you know which SunPower you are dealing with. The new SunPower used to be called Complete Solaria. It scores 80 out of 100 on our public-records formula, 4th of 20 in our Texas ranking. It has no lawsuits or state actions in five years and an A+ BBB grade. Its workmanship warranty lasts 10 years and covers roof leaks. It also gives a written production guarantee. It lost points for posting no prices or loan fees. The old company’s 25-year promises did not carry over.

01 · Which SunPower

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:

  1. Complete Solar starts

    The company behind today’s SunPower is founded. It later grows into Complete Solaria.

  2. The old SunPower goes bankrupt

    SunPower Corporation, the famous original, files for bankruptcy.

  3. 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.

  4. BBB accreditation

    The new SunPower’s Utah BBB profile becomes accredited, with an A+ grade.

  5. Sunder Energy joins

The new company explains what it took on in 2024 on its company history page.

02 · Old-system finder

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.

03 · The score

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.

04 · Warranty

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.

Worth asking: who would keep your 10-year promise if this SunPower closed too? The name has already changed hands once. SunPower does not name an insurance company or any other company that would take over. Our formula saves 3 points for that kind of backup. No installer we review has earned them yet. How we score warranty backup.
05 · Complaints

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.

Billing, loan or refund problems21Slow or no response13System not working or making less power10Warranty or repair service10Sales promises not kept7Roof leaks or roof damage2Install, permit or approval delays2
How often each problem came up in SunPower’s 30 newest BBB complaints, July 16 to September 10, 2026. One complaint can raise more than one problem.

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.

06 · Who installs

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.

07 · Price

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.

08 · Where it sells

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.

09 · 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.

  1. Which company am I signing with? The contract should name SunPower Inc. Make sure the warranty comes from the same company.
  2. Who will install my system? Get the crew or company name and its license number in writing.
  3. What does the production guarantee promise? Ask for the yearly amount and what SunPower pays if your system falls short.
  4. Are any checks or rebates promised to me? Put the amount, who pays it and the date in the contract.
