A PV power system on the flat roof of an industrial building was investigated by flight thermography using a remote controlled octocopter. The PV system was known to show significant power reduction within in the first year of operation. The investigation of about 350 solar modules could be performed within only one hour, including the preparation of the octocopter, the thermography flight itself and subsequent analysis. About 10 percent of the modules were identified to show potential-induced degradation (PID) and could be attributed to that part of the strings with negative potential. PID affected modules were dismounted and analyzed in the laboratory showing a power degradation of up to 60%.
