The warranty itself also guarantees that your panels should still produce at least 80 of their initial output peak rate after 20 25 years depending on the panels or manufacturer. Most solar panels used in home solar arrays come with a warranty for some 25 or 30 years which means that the solar panels are guaranteed for decades unlike many of the other goods we buy.
