SunPower Launches 25-Year Solar Power/Product Warranty

SunPower Corp. has launched a combined warranty that covers both power and product for 25 years.

In the event a solar panel needs to be repaired or replaced, an identical or functionally equivalent panel will be provided, or the cost of the panel will be fully refunded.

The associated labor and transportation costs for customers whose solar panels were installed by SunPower or SunPower dealer/partners are covered. The company guarantees at least 95% power for the first five years, followed by a maximum degradation rate of 0.4% each year thereafter.

The new warranty went into effect on July 1 and is available to all residential, commercial and utility-scale power-plant customers who install SunPower solar panels.
