Fraunhofer ISE research finds solar module output ‘often overstated’

A longitudinal research project from the Fraunhofer Institute for Solar Energy Systems ISE reveals that since 2017, the institute has measured less power on average in a solar module than promised by the manufacturer.Research by the Fraunhofer Institute for Solar Energy Systems ISE (Fraunhofer ISE) has found a negative trend emerging between performance data from PV module manufacturers and the institute’s performance measurement of the module s…

The researchers have measured more than 70,000 solar modules in the calibration laboratory "CalLab PV Modules" since 2012. In the first years, the measurement results were mostly above the information provided by the module manufacturers, but since 2017, the researchers have seen a opposite trend, which so far culminated in deviations of an average of 1.3 percent in 2023. Do the products hold what the manufacturers promise? This general question…
