ECN is very pleased with the equipment that Eternal Sun has supplied. We are now able to measure behaviour of PV modules that we were not able to measure before. We as ECN think that it is phenomenal that the Netherlands are in the lead when it comes to scientific research in the solar industry. Companies such as Eternal Sun attribute a great deal to this. We are pleased to be able to attribute to the growth in this industry.”

TNO Technical Science is active in research on CIGS solar cells. Within our research group, my project focuses on the degradation behavior of this type of solar cells. We developed a unique hybrid degradation test setup, for which we purchased a solar simulator from Eternal Sun, which we have combined with a climate chamber.  We are pleased with the performance of the solar simulator, which has been in use for over 12.000 hours and we expect to obtain many more interesting test results with it in the future.”

”The new institute of Polish Academy of Sciences is dedicated to research and developments in the field of conversion and storage of renewable energy. Among the many laboratories located there, the solar laboratory is one of the most significant and representative ones. We are very please to cooperate with Eternal Sun, who delivered their highly advanced equipment dedicated to testing both solar thermal and solar photovoltaic technologies to our Institute. This makes our laboratory very well equipped on a global level.”

TU-Delft_logo”As head of the Photovoltaic Materials and Devices group of Delft University of Technology in the Netherlands, I was responsible for the acquisition of one of the first Eternal Sun Large Area Solar Simulators. We use the test facility for education, research and testing of PV modules for third parties. We are happy to have the possibility to perform various tests on all kind of PV modules at our department. We believe other organizations active in Solar Energy would also benefit from having such a test facility.”
