Installation of 50kW ground mounted PV system making progess: Subconstruction and PV modules already installed. The PV system is part of our joint research project with Institut for Photovoltaics of University of Stuttgart "park" funded by the German Government (Förderkennzeichen 0324069a). Here, we installed 190 PV modules which received hail damage during a very intense hail in 2014. During the next years, we will investigate the power loss on module as well as string level. Further, we will check the modules for degradation and risks frequently.
