Warranty

SunPower is the only solar panel manufacturer that has been in business longer than its warranty

SunPower offers a Best-in-Class 25 year warranty. We offer our customers complete confidence with our comprehensive warranty that covers not only power production, but also the panels, micro inverters, and racking. We also offer a 10 year warranty on workmanship. Our competitors simply can not match this.

If you experience any issues with your system within 25 years of purchasing your SunPower system, we will send a certified installation contractor to resolve the issue. We stand behind both our product and our workmanship. Since we are locally owned and operated, we are nearby to answer questions or concerns.
