Expert SunPower review 2025: New Ownership

SunPower has entered a new era. In 2024, the brand, intellectual property, and key operational divisions of the previous SunPower Corporation were acquired by Complete Solar (now operating as SunPower). The new SunPower is a residential solar and energy services provider, combining the expertise of the former companies to deliver flexible, high-quality solar solutions.

Here are some of the pros and cons of going solar with the new SunPower:

How much does a SunPower installation cost?

SunPower solar installations have historically cost about $3.30 per watt of solar installed, which is higher than the average solar installation price. The higher price is attributed to SunPower's premium equipment and comprehensive warranty coverage.

This premium offering is backed by SunPower’s corporate strategy: the company maintains internal control over all system components and the sales process, ensuring a consistent level of quality and service.

It’s hard to determine an exact price for a solar installation – everyone’s situation is unique! The total price of a solar installation can vary with how many solar panels you need, where you live, and even how you pay for the system!

To give a better idea of how much you can expect to pay, the chart below breaks down the price of a SunPower installation based on different system sizes:

System size	Avg. SunPower price*
4 kW	$13,200
6 kW	$19,800
8 kW	$26,400
10 kW	$33,000

_{*based on historical SunPower pricing before the 2024 transition; actual pricing may differ.}

Does SunPower offer payment options?

Yes, if you don’t have the funds to pay for your system upfront, you can finance your solar system using SunPower flexible solar plans. SunPower offers a few financing options to homeowners:

Third-Party Ownership (TPO) Options

These options allow you to get a solar system with little to no upfront cost. SunPower partners with leading TPO providers, including Lightreach and GoodLeap.

Option	Payment Structure & Key Features	Financial Benefits
Solar Lease	Fixed monthly lease payment for 20-25 years, regardless of production. The financier owns the system and provides all maintenance, monitoring, insurance, and system replacements if needed.	Predictable, stable monthly cost; protection from utility rate increases; zero maintenance or repair expenses; easier qualification than solar loans.
Power Purchase Agreement (PPA)	Customers pay a fixed rate per kilowatt-hour (kWh) produced, typically below utility pricing with a moderate annual escalator. No payment when the system does not produce. The financier owns the system.	Guaranteed discounted rate vs. utility; pay only for actual energy produced; no risk of paying for underperformance; protection against utility rate spikes.

_{Note: Financing providers are third-party entities and are not owned by SunPower.}

If you want to maximize your savings, the best payment option is purchasing your system upfront. 

SunPower's Solar Panel Solutions

The new SunPower no longer has an exclusive agreement with a single manufacturer. The company is now brand agnostic but committed to sourcing and installing high-performance, high-efficiency panels.

SunPower now selects best-in-class solar modules from multiple trusted global suppliers. This flexible approach ensures customers receive modern, high-quality panels optimized for their specific roof and energy needs, maintaining the high standard of efficiency previously associated with the SunPower brand.

What is SunPower’s warranty?

SunPower remains committed to providing comprehensive solar warranty coverage.

• Battery Warranty: The Enphase IQ Battery 10C comes with a strong 15-year limited warranty (or up to 6,000 cycles) directly from the manufacturer, Enphase Energy.

What do customers think of SunPower?

Customer reviews for SunPower are generally positive regarding the technology.

SunPower has historically maintained high average ratings on review platforms, often scoring around 4.5 out of 5 stars. The most common feedback highlights the high quality of the system components and the quick, professional nature of the installation process.

Keep in mind that SunPower is a nationwide company, and local reviews in your area are the most important ones to look at. Since the original SunPower Corporation filed for Chapter 11 bankruptcy in 2024, many of the reviews you’ll find online may reflect experiences from before that transition.

Where is SunPower available?

SunPower leverages its national sales and installation footprint to operate across many of the country’s largest residential solar markets. To determine exact service availability for installation and battery storage in your specific area, it is best to consult the SunPower website.

Bottom line: Is SunPower the right choice for you?

The new SunPower represents a strong option for homeowners seeking a comprehensive, flexible, and premium solar and storage solution. By combining the strong national sales and in-house installation capabilities with the renowned SunPower brand legacy, the company offers high-quality, brand-agnostic panels and the industry-leading Enphase IQ Battery 10C.

While the systems are priced at a premium, the array of $0-down financing options (including Solar Lease and PPA) and a dedicated focus on customer service and quality make SunPower a competitive choice, particularly for those prioritizing the benefits of a full-service national provider. As always, compare quotes from at least three different companies to ensure you find the best value for your specific home and energy needs.

At SolarReviews, we recommend contacting at least three installation companies and comparing each quote. Comparing multiple solar quotes not only gets you the best installation possible but also the best price.
