Outdoor Efficiency Measurements and Test Fields

For determination of the module performance under real outdoor conditions, Fraunhofer CSP has different measuring setups in use for characterizing up to 36 individual modules. IV-Curves, power as well as module temperature and weather data is measured synchronously. Every module is operated in its maximum power point (MPP) between the measurements.
Various kinds of installations can be realized due to the different test setups: Fixed mounted open area, roof test site or a variable module orientation due to a free programmable 2 axis Solar-Tracker. The measured data is checked regarding different quality criteria to guarantee reliable data set for energy yield analysis.
