To simulate the operation behaviour of PV systems, time series of meteorological data are required. For this
investigation measurements from the metrological observatory Lindenberg, Germany, located at 52.21°N, 14.12°E
in the south-east of Berlin, are used. The measured values are captured by the German weather service (DWD) in
the framework of the Baseline Surface Radiation Network (BSRN). The global and diffuse irradiance on the
horizontal plane as well as the air temperature are available as one minute average values from the year 2002 until
2006. The measured values of the year 2004 with a horizontal global irradiation of 1073 kWh/m² are used as a
reference.
