For planning and monitoring of large scale solar parks an exact as possible prediction of the energy yield is essential. In this work we investigate the solar spectrum for one location (48°15'N, 11°39'E). Spectral data of the incoming global irradiance from 300 to 1680 nm, the electrical parameters of a commercial CdTe and a CIGS solar module and weather data such as global, direct and diffuse irradiation, ambient temperature and humidity are recorded with a high temporal resolution of less than 10 seconds which allows also the investigation of short term meteorological effect such as cloud enhancement and fast moving cumulus clouds. Furthermore photographic weather records support the evaluation. Aerosol, ozone and water vapor data from the AERONET database are consulted to evaluate spectral variations. Experimental results are compared with simulations from the SMARTS2 and the SANDIA model.
