- Top-end configurations may reach $ 4.00 per watt, especially with premium panel models and financing markup.
What Affects These Prices?
Several key factors influence the cost of SunPower solar panels. The total price of a larger system is usually higher, but the cost per watt can decrease due to economies of scale. Prices are also influenced by the type of equipment and the system’s configuration. For example, microinverters, advanced racking systems, and high-efficiency panels, such as the Maxeon X- or M-series, all contribute to the overall cost.
Different areas of the U.S. have varying work rates and permit requirements, resulting in price differences. Also, the type of business model used by the installer—whether it’s a full-service or dealer-based model—often causes overhead costs to vary. Lastly, how you pay is essential. If you finance a system, the price per watt is typically higher than if you pay cash upfront.

SunPower Bankruptcy
SunPower Corporation filed for Chapter 11 bankruptcy in August 2024, which meant that its home solar business would undergo significant changes. The decision was made after months of financial stress caused by falling demand, accounting delays, and debts that had grown to over $2 billion. The company isn’t entirely out of business. Still, it had to file for bankruptcy and sell some of its most important assets to Complete Solaria, which acquired SunPower residential companies, including Blue Raven Solar.
This change has made service and support less clear for existing customers; however, warranties on equipment made by third-party companies, such as Maxeon and Enphase, remain valid. Even with this issue, SunPower-branded devices continue to function, and many dealers remain available to offer assistance in various ways.
What SunPower Customers Need to Know
As long as you have a SunPower solar system, your panels will continue to function, but you may experience difficulties obtaining service. Users can no longer use the official customer support portal or app. Instead, they must rely on the installers who installed their products or directly contact the component makers to make warranty and maintenance claims.
Existing warranties remain valid, even though SunPower has filed for bankruptcy; however, labour or service coverage may be limited according to the terms of the warranty. To ensure their system works well in the long term, customers should gather all relevant paperwork for their system and consider seeking additional assistance from third-party companies, such as Solar Insure or local solar technicians.

Sustainability and Environmental Impact
SunPower has established a reputation as one of the world’s most eco-friendly solar panel manufacturers by prioritizing long-term growth and sustainable production methods. Its Cradle to Cradle CertifiedTM products demonstrate that it is transparent about how its products are made.
This is a widely recognized standard for products made with safer, more sustainable materials and ethical methods. This certification demonstrates that SunPower is a leader in producing solar panels that not only generate clean energy but also cause minimal environmental impact.
In addition to production, SunPower systems significantly reduce carbon emissions. A single SunPower solar system can, on average, offset about 5 tons of CO2 emissions per year. That’s about the same as planting over 100 trees every year. Because of this, SunPower is an excellent choice for homeowners who care about the environment and want to switch to green energy while also doing so.
