ABSTRACT
In this paper, we describe a remote performance check for grid connected PV systems. No additional hardware installation will be necessary on site. The site specific solar irradiation data will be derived from satellite images rather than from ground based measurements. On the basis of monthly irradiation time series, monthly values of PV system yield will be calculated and distributed automatically towards the system operator. He or she may then compare the estimated production to the real production meter reading. First tests reveal an overall accuracy of about 10 % for that period of a year offering 90 % of the annual solar irradiation.
