The aim of this research is in one hand to reveal the real energy production of a medium scale Photovoltaic (PV) plant located at different sites in Greece and on the other to compare measured data to the predicted ones resulted from one well-known, PV simulation software. During the last ten years a capacity of more than 2,5 GWp of PV systems has been installed in Greece. Almost 37% of the installations are ranged from 10 to 100 kWp due to favorable Feed-in-Tariff policy pricing, according to the Greek regulation. Previous investigations proved a remarkable difference between measured and predicted energy production in Greece regarding all PV systems technologies. For the purposes of this study more than 250 medium scale PV plants have been measured and more than 850 annually energy production data series for those parks have been collected. Those data constitute a great sample that has been compared to more than 225 simulations data resulted by a well-known web software for PV systems energy yield calculations with improved solar radiation database. Additionally, in order to have a visual feeling concerning the real PV energy yield footprint in Greece, an updated map has been developed and illustrated, providing a useful tool for both business and academic purposes.
