Schott upgrades its guarantee on solar power modules


Schott Solar has introduced a new extended performance guarantee, switching over its warranty on solar power modules from being a graduated to a linear digressive model, guaranteeing customers higher performance than before for each year covered by the guarantee period.

Schott previously extended its warranty on its glass-foil modules to 25 years and to 30 years for its double glass modules and also introduced 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. Now, the company will be guaranteeing output of at least 97% 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.  

Dr. Martin Heming, chairman of the board of management and CEO of Schott Solar 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.”
