KYOCERA Solar Modules Independently Tested Show Excellent Performance After 10 Years of Operation at Europe’s Largest Solar Research Institute
Installation at the Fraunhofer Institute for Solar Energy Systems (ISE) in Freiburg, Germany is still highly efficient with output degradation of just 5 percent

“The low output degradation of five percent over the past 10 years is evidence of the excellent quality of Kyocera solar modules. We are already eager to see the measurements following the next period. In the past five years, we have measured stable efficiency in the lab as well as the field, so we expect the result to be just as good in terms of quality,” said Anselm Kröger-Vodde, Project Manager for Photovoltaic Modules, Systems and Reliability at Fraunhofer ISE. Kyocera is one of the few companies on the market to maintain a vertically integrated production system. This system allows full monitoring of product quality at each step which helps ensure the performance of every cell and solar module over an extended period of time.
Kyocera is also one of the few makers of solar modules on the market to possess such long-term studies of its products under real-life conditions. A similar test system is located just outside of Tokyo, Japan and has been in operation for almost 30 years. The most recent measurements, taken five years ago, revealed a degradation of just 9.6 percent. With such real-world data to stand on, Kyocera is confident in offering its customers a 25-year guarantee of 80 percent of nominal output.
* The 2.25-kWp PV system consists of 18 Kyocera KC125G modules and an SMA SunnyBoy 2100TL inverter. The modules are installed at an alignment of 0° and a tilt of 29°.
