Warranty

SunPower is the only solar panel manufacturer that has been in business for 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 cannot match this.

If you experience any issues 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.
