Aerial PV Inspection GmbH and the Institute for Solar Energy Research (ISFH) cooperate in a ZIM research project (FKZ ZF4523002LT9) funded by the Federal Ministry for Economic Affairs and Energy (BMWi). The aim of this cooperation is to increase the error detection rate of AI-based analysis software. In addition, the future yield of PV modules is to be evaluated by electroluminescence and UV inspections. This project is an important step on the way to optimizing large PV systems at low cost.
