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

Kyocera Corporation (President: Goro Yamaguchi) announced today that its solar modules installed at the Fraunhofer Institute for Solar Energy Systems (ISE) have been independently tested and their performance levels verified, showing an exceptional output even after 10 years of operation. Europe's largest solar research institute in Germany, ISE installed a test system with the Kyocera modules equipped with high-precision measuring equipment that confirms an output degradation of just five percent after a full decade of maximum use. Researchers regularly analyze operating data and check the output of random modules annually in Fraunhofer ISE's test lab, which have determined the Kyocera KC 125G modules* still deliver excellent results.


"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 Krger-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°.

RBI Solar - Dahlia Has You Covered

What if you could maximize the Ground Coverage Ratio (GCR) on your next project and not have to worry about the complicated variables that come with a tracker system? With a low tilt and clearance design, Dahlia® has the highest GCR of any fixed-tilt system in the marketplace. The system is available in three tilt options (7.5, 10 and 12.5 degrees) and designed to accommodate any sized PV module. The lightweight system is engineered with fewer components, several of which are shipped to job sites pre-assembled. This design feature reduces freight costs and rapidly trims the amount of on-site installation time required to complete construction. Maximizing PV coverage on a site can lead to an increase of production, which creates greater financial return for project owners. Over 100 MW of Dahlia® projects have been deployed across the United States, in regions of variable snow and wind loads. How much can Dahlia® cover and save you on your next project?
