Abstract
A method and an apparatus for carrying out the method are proposed for identifying defective photovoltaic modules. Two clamp-on ammeters are provided which are connected to a test data acquisition unit for simultaneous measurement of two DC currents. The position of the clamp-on ammeters at the time of the measurement is determined with a position registration means, and measured data and position data are transmitted via an antenna to a data processing center or recorded in a data memory element for further processing.
