SCHOTT Solar extends performance guarantee on solar power modules

25 years for glass-foil modules, 30 years for double
Continuous plus tolerance with all modules
Fraunhofer Institute confirms performance in long-term test

SCHOTT Solar AG continues to pursue its quality strategy and is now extending the guarantee conditions for its solar power modules. Effective immediately, the company is offering a 25-year performance guarantee on glass-foil modules and even a 30-year guarantee on double glass modules.

In addition to the new guarantee terms, SCHOTT Solar has introduced so-called continuous plus tolerance. This means that all of the modules that belong to a performance class generate at least the nominal power listed. These measures increase efficiency quite considerably for those who own photovoltaic systems and underscore the premium quality that SCHOTT Solar offers.

According to the Chairman of the Management Board and CEO Dr. Martin Heming, the company had good reasons for making this decision: “SCHOTT Solar looks back on a 51-year tradition in the area of solar modules. Many of our systems have been delivering high performances that have remained stable for decades. The tests we perform are twice as rigorous as the industry standard. The excellent results that we achieve clearly demonstrate our strong confidence in the quality of our products. Now, with the extended performance guarantee, customers will benefit even more from their decision in favor of SCHOTT Solar,” he adds. The extended conditions apply for products that have left the warehouse since August 24, 2009.

A renowned organization even confirms the company’s high standards for quality. The Fraunhofer Institute for Solar Energy Systems (ISE) evaluated a solar system from SCHOTT Solar with the help of an endurance test and attested that this system yielded outstanding values. On top of the roof of the Institute’s building in Freiburg, the system has been in operation for 24 years, yet shows extremely low degradation of only 5.5 percent on average. For customers, this means decades of reliable performance and high yields, as a result.
