let me know where you can buy solar panels with a 25 year warranty. I'll go buy some to replace my dead ones.
SunPower Solar Systems SunPower Solar Panels come with a 25 year warranty on the power production of their panels. Because there are no moving parts, the only wear-and-tear these systems see if from the sun beating on them year after year. This is factored into the 25-year warranty, which states that by the end of the twelfth year, the panels should still be producing at 90% of their initial capacity, and that by the end of the 25th year, they should still be producing at 80% of their rated power.
