    Someone asked my why we only have a fairly good idea about the warranty. We know what the warranty is today, but that’s only as good as the company backing it. We have seen major manufacturers go bankrupt (i.e. Evergreen Solar), and the status of warranties become unclear. In the case of module manufacturers not honoring a warranty, the likelihood (risk) of a solar module not meeting production expectations or failing due to poor workmanship is extremely low. Most warranty issues are seen with the electronics, specifically inverters. Fortunately, some manufacturers are coming out with 25 year warranty on the electric components as well, further reducing risk.

    Unfortunately, risk cannot be totally eliminated with a warranty. One strategy undertaken by some manufacturers, like Canadian Solar, is to back the warranty with an insurance policy that covers potential warranty claims even if the company goes under. This strategy is creating peace of mind for consumers and investors.
