Sunrun vs SunPower: What Changed After SunPower's Bankruptcy and How They Compare Now
Sunrun mostly sells long-term leases and PPAs it services itself. Today's SunPower is a different company from the one that went bankrupt in 2024. Here's how they compare.
Sunrun vs SunPower comes down to ownership and long-term coverage. Sunrun mainly sells 25-year leases and PPAs where it owns, monitors and repairs the system, while today's SunPower (SunPower Inc., formerly Complete Solaria) mostly sells systems you own, backed by a 10-year workmanship warranty and manufacturer warranties of up to 25 years. Before comparing, know that the SunPower selling solar now is a different legal company from the SunPower Corporation that filed for bankruptcy in August 2024.
Facts below were checked against company pages and recent reviews in November 2026.
Key takeaways
- SunPower Corporation filed for Chapter 11 on August 5, 2024. Complete Solaria bought some of its assets and rebranded as SunPower in April 2025.
- The new SunPower did not take on old SunPower leases, PPAs or systems installed before its September 30, 2024 acquisition (Blue Raven Solar and Complete Solar customers are handled separately).
- Sunrun includes 25 years of maintenance and repairs and a 90% production guarantee on monthly lease and PPA plans (not in Florida).
- SunPower Inc. offers two years of service coverage, a 10-year workmanship warranty and its own production guarantee.
- The federal 25D credit is not available for expenditures made after December 31, 2025, which for solar means installations completed after that date.
Which SunPower are we comparing?
This matters for anyone shopping now. According to EnergySage's April 2026 update:
- August 5, 2024: SunPower Corporation filed for Chapter 11 bankruptcy.
- September 30, 2024: Complete Solaria completed its purchase of SunPower's Blue Raven Solar business, New Homes division and dealer network for $45 million.
- April 21, 2025: Complete Solaria announced its rebrand to SunPower.
- October 2025: the company changed its legal name to SunPower Inc.
- September 2025: SunPower Inc. acquired Sunder Energy, expanding its installation footprint from 22 to 45 states.
EnergySage says SunPower Inc. operates mainly through Blue Raven Solar, and its website lists an address in Orem, Utah. If you already have an older SunPower system, see our solar orphans help page and the section on legacy customers below.

Plans and financing types
Sunrun
Sunrun's core product is the 25-year subscription, a monthly lease or PPA. It also offers Flex (in Texas, Illinois and California), a prepaid plan that covers 25 years with one payment and no escalator, and cash purchase. Sunrun's annual report for 2025 (Form 10-K, filed February 2026) says initial terms are typically 20 or 25 years, and that at the end you can renew (typically at a 10% discount to then-current power prices), buy at fair market value or have the system removed.
SunPower Inc.
SunPower's current site advertises residential solar, Enphase 10C and 5P batteries and a 25-year manufacturer warranty. A financing guide on its site describes loans, leases and PPAs, but the page is not dated and does not say whether it predates the 2024 bankruptcy, so treat any rate it mentions as out of date. Ask for the actual financing offer in writing, including any dealer fee. A low advertised loan rate can come with a higher system price, so compare the cash price and the financed price side by side.
Warranties and guarantees compared
The warranty structures are very different because ownership is different.
Sunrun owns the system, so it fixes it. The Sunrun Guarantee covers 25 years of maintenance and repairs, including parts and labor, and 24/7 monitoring. On monthly lease and PPA agreements, Sunrun guarantees at least 90% of estimated production and pays the difference if output falls short. It is not available in Florida, and Illinois terms differ.
SunPower Inc. sells you the system, so long-term coverage comes from warranties. Per its warranty page:
- Two years of service support after installation, including inspection and coordination of eligible repairs at no cost
- A 10-year workmanship warranty covering installation quality, roof penetrations and design issues
- A production guarantee: if output falls below 50% of projection for 3 consecutive months, or below 85% for 18 consecutive months, SunPower adds panels or compensates you
- Manufacturer warranties of up to 25 years on panels and microinverters; after year two, you pay any manufacturer claim fees
In plain terms, the trade-off looks like this. With Sunrun, an inverter failure in year 15 is Sunrun's job to fix under the subscription. With a system you buy from SunPower Inc., that same failure is covered only if it falls within the manufacturer's warranty, and you may owe claim fees or labor after the early years. On the other hand, owning means no monthly solar payment once a loan is paid off, and no annual escalator.

Already a SunPower customer?
If your system was installed before SunPower Inc.'s September 30, 2024 acquisition, SunPower Inc. generally did not take responsibility for it. (SunPower says warranties in Blue Raven Solar and Complete Solar installation agreements remain valid.) SunPower's own guidance says:
- Lease or PPA customers should contact their financier or SunStrong Management at (833) 514-1858.
- Cash or loan customers should contact their lender.
- Manufacturer warranties (for example Enphase, Qcells, REC, Fronius) are separate; EnergySage reported in April 2026 that most major manufacturers are still honoring them.
- If old monitoring stops working, Enphase offers a Monitoring Upgrade Kit that replaces the SunPower Corporation combiner box.
Sunrun's FAQ says it does not add panels to a system that is already installed and that a second system is contracted under its own agreement. If you have a legacy SunPower system, ask any new installer, including Sunrun, in writing whether it will service the existing equipment.
If you own a legacy SunPower system and want more capacity, a new installer, including Sunrun, would treat it as a separate project. Keep your original installation agreement handy, because it lists the panel and inverter makers you will need for any warranty claim.
Owner reviews and reputation
We do not rank installers. You can read owner reviews on our Sunrun page and SunPower page. Look for patterns in how each company handled service visits, billing questions and production shortfalls, since those matter most over 20 years or more. With SunPower, check the date of any review: reviews written before 2025 usually describe the old SunPower Corporation or its dealers, not SunPower Inc.
How to choose between Sunrun and SunPower
- Want no upfront cost and no repair bills? Sunrun's subscription model is built for that, but you pay an escalating monthly bill and never own the system unless you buy it.
- Want to own the system? SunPower Inc. focuses on ownership, which means you take on repairs after the warranty periods.
- Worried about company risk? Ask each company who services your system if they are sold or close. Get the answer in writing, and keep copies of every warranty document.
- No tax credit either way for new systems. The IRS says the residential clean energy credit is not allowed for expenditures made after December 31, 2025, and a solar expenditure counts as made when installation is completed.

Frequently asked questions
Is SunPower still in business?
SunPower Corporation filed for bankruptcy in August 2024. A different company, formerly Complete Solaria, bought some of its assets, rebranded as SunPower in April 2025 and now operates as SunPower Inc.
Who services my old SunPower lease?
SunPower says legacy lease and PPA customers should contact their financier or SunStrong Management at (833) 514-1858. The new SunPower did not acquire those contracts.
Does Sunrun offer a better warranty than SunPower?
They work differently. Sunrun covers maintenance and repairs for 25 years because it owns the system, while SunPower Inc. offers a 10-year workmanship warranty and manufacturer warranties of up to 25 years on equipment you own.
Can Sunrun take over my SunPower system?
Sunrun's FAQ only says it does not add panels to an installed system and contracts any second system separately. EnergySage says owners of legacy SunPower systems can use any licensed solar company, while lease and PPA holders go through the company that holds their agreement.
Is there still a federal tax credit for Sunrun or SunPower systems?
No for new home systems. The IRS says the residential clean energy credit is not allowed for expenditures made after December 31, 2025, and a solar expenditure counts as made when installation is completed.
