Product Warranty

When you purchase SunPower solar panels, the product guarantee is designed to take you all the way. Unlike a traditional solar warranty, the SunPower product warranty lasts for 25 years, and covers all costs associated with panel replacement. In the unlikely event that there is an issue with your solar installation or a panel needs to be replaced, the cost of the solar company removing the malfunctioning panel, shipping the new panel, and the panel’s installation is covered.

Power Warranty

SunPower panels are guaranteed more lifetime energy, more power, and less degradation than conventional panels. This advantage increases over time. More lifetime energy means panels guaranteed to produce 3% more energy than conventional panels at year five, and 12% more the twenty-fifth year. More power means your panels will produce at least 98% of the Minimum Peak power for the first year. Less degradation means an unparalleled annual degradation of less than 0.4% for the subsequent 20 years, making your panels produce at least 92% of the Minimum Peak power their twenty-fifth year.
