SunPower Review 2026: The Complete Solaria Rebrand, Explained

The SunPower name is one of the most recognizable in U.S. residential solar — but the SunPower you'd hire today is not the same legal entity that existed two years ago. In August 2024, the original SunPower Corporation filed Chapter 11 bankruptcy. In early 2025, Complete Solaria acquired the key operating assets for approximately $45 million, then rebranded itself to SunPower in April 2025 and reclaimed the SPWR ticker on Nasdaq. Here's what that means for California buyers in 2026.

What "SunPower" Actually Is Now

Today's SunPower is a publicly traded company headquartered in Fremont, California, operating in more than 45 states. Q4 2025 revenue was approximately $88.5 million, with full-year 2025 revenue around $308.8 million. The company has publicly stated a growth target of roughly $1 billion in revenue by 2028, which implies an aggressive expansion pace.

The entity is in early-stage post-restructuring, which means the combination of recognizable brand equity and an early-days balance sheet. For a California buyer making a 25-year decision, that's a trade-off worth understanding before you sign.

Equipment and Installation

SunPower does not manufacture its own panels. The legacy SunPower brand was historically associated with high-efficiency Maxeon panels — that manufacturing relationship was unwound through the 2024 bankruptcy, and today's SunPower sources Tier-1 panels from multiple suppliers. Inverter choices include Enphase microinverters among others, depending on market and project. Batteries are third-party, most commonly Tesla Powerwall or Enphase IQ.

Installation uses a hybrid model of direct crews and a dealer network. This is similar structurally to Freedom Forever's pre-bankruptcy model and comes with similar trade-offs: faster geographic expansion, but more variability in install-crew quality compared to fully in-house operations.

Pricing and Timeline (California)

Historical California pricing has run approximately $2.80 to $3.20 per watt, which is competitive but not the lowest on the market. Install-to-PTO timelines typically run 1 to 4 months depending on your utility's interconnection queue and whether the local crew is direct or dealer-installed.

What Happens to Legacy SunPower Customers?

This is the most commonly asked question about today's SunPower. If you bought from the pre-2024 SunPower Corporation, your warranty obligations and service contracts were part of the bankruptcy and the asset sale. Today's SunPower has continued to service many — but not all — of the legacy obligations that transferred in the asset purchase. Legacy complaints around warranty responsiveness and service delays have continued to appear in consumer review channels through 2025 and into 2026.

If you're a legacy customer with pending warranty issues, the first step is to confirm in writing which entity is responsible for your specific contract. Separately, manufacturer warranties on your panels, inverter, and battery are from the equipment makers themselves (Maxeon, Enphase, etc.) and are not affected by the SunPower corporate restructuring.

Reputation and Complaint History

BBB and Trustpilot profiles for SunPower carry a mix of legacy complaints (from before the bankruptcy) and newer complaints (from post-rebrand installs). Average composite ratings across Trustpilot and SolarReviews sit in the 2.8 to 3.5 range. The legacy complaint base is still meaningful — pre-2024 SunPower was subject to lawsuits covering deceptive practices and service failures, and some of that reputational residue carries into the new entity's online profile.

Warranty

SunPower continues to offer 25-year performance and product warranties on new installs, consistent with industry standard. Legacy warranty obligations are being honored where they transferred as part of the asset sale. Because the entity is early-post-restructuring, long-duration warranties on new installs carry more balance-sheet risk than they would from a more established public installer.

When SunPower Makes Sense

SunPower is a reasonable option for buyers who specifically value the brand recognition, want competitive mid-market pricing, and are comfortable with a company still building its post-restructuring track record. The install-phase experience is typically fine; the variability shows up more in post-install service and long-tail warranty confidence.

It's less compelling if warranty durability is your top concern, if you want a longer operating history on the current entity, or if you're specifically seeking a vertically integrated panel manufacturer — today's SunPower does not manufacture its own equipment.
