This work was facilitated by Cyprus International University under the supervision of the Vice Rector and Energy Expert, Assoc. Prof Serkan Abbasoglu. It presents the analysis and evaluation of data from a real world photovoltaic system at Cyprus Solar Technology (CYS) in Nicosia, Northern Cyprus. It also compares the evaluation with simulation results of three globally known PV software tools: pvPlanner, PVsyst and Homer. The parameters evaluated in this study are energy production, specific yield, performance ratio and capacity factor. CYSs results were first analyzed with respect to the...
