Schott Solar is changing its warranty on solar power modules from being a graduated to a linear digressive model, thus guaranteeing clients higher performance for each year covered by the guarantee period. Schott had already extended its warranty on its glass-foil modules to 25 years, and to 30 years for its double glass modules, as well as introducing continuous “Plus Tolerance“ in September 2009. Schott“s previous warranty on PV modules guaranteed that output would remain at a constant level of 90% for the first 10 years and 80% beyond that period. As per the new warranty, output of at least 97% will be guaranteed for the first year, declining by 0.7% per year on glass-foil modules and 0.5% on double glass modules for the remaining period. Chairman of the board of management and CEO of Schott Solar, Martin Heming, said, “With our new performance guarantee that has been improved from the customer“s point of view, we are setting clear accents in competing at a time when buying decisions are highly dependent on being able to achieve returns without having to take any risks. We view this measure to be an important step in further strengthening consumer confidence in us as a manufacturer.”
