In 1984 Schott Solar installed solar modules on the Fraunhofer Institute in Freiburg and 26 years after their installation the Fraunhofer Institute for Solar Energy Systems (ISE) confirmed that the modules average 92% of their initial output. During their original installation in 1984, the 53 modules had a guaranteed output of 90% after ten years with an average performance of 38.4W. Today not only do they average 92% of their initial output, but also average 35.3W.
“A crucial factor in customers’ decision-making process in favor of investing in a photovoltaic system is that solar modules sustainably deliver high output levels for a period of more than 25 years. We are delighted that the renowned ISE institute has confirmed the consistency of Schott Solar modules’ output in an independent test, giving potential buyers valuable guidance in decision-making,” explained Dr. Martin Heming, CEO of Schott Solar. “Our quality modules provide every operator with high calculable yields, which we are now backing up with our enhanced output guarantee.”
