AB  - This study links chemical analysis of PV-module’s backsheet components with the monitored yield andvoltage of PV. WE investigated several PV-systems all with two or more module types and differing backsheet types. Weidentified three classes of backsheets with respect to their influence on module performance. First, double-fluoropolymersare robust and modules perform constantly well over years. Second, non-fluoropolymers, show approximately linearperformance and degradation and third, single-fluoropolymers show drastic performance losses, including inverter shutdowns. Humidity was identified as an important driving factor for the faster ageing process of modules with criticalbacksheets und isolation issues. A correlation between obvious backsheet defects, e. g. cracks or isolation issues andinverter shut-downs was not found.
