'ABSTRACT This study 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. CYS's results were first analyzed with respect to the meteorological condition of Nicosia; then, they were compared with the values obtained from the three simulators. Detailed explanations are provided for the monthly, seasonal and annual variation of CYS data and simulation results in this study. Solar PV thrives in regions where there is high irradiation and long sunny hours; such as Cyprus. The total annual energy production at CYS amounts to 12,216 kWh for the year studied. All the simulation tools appear to underestimate CYS's energy production and the variances observed are 5.3%, 9.3% and 7.5% for pvPlanner, PVsyst and Homer respectively. Energy production in summer was observed to be about twice of the production in winter. The percentage share with respect to energy production are 34%, 28%, 22% and 16% in summer, spring, autumn and winter, respectively. The performance ratio of the system at CYS is 80.8%. The simulators modeled average performance of 78.6%. PVsyst modeled a performance ratio with the least deviation from CYS which is 79.2%. The specific yield and capacity factor of CYS are found to be 2121 kWh/kWp and 25.06% respectively. The average specific yield value and also average capacity factor of the three simulators are nearly 7% lower than measured data at CYS. Different reasons led to the difference between real world application and simulation results. These reasons are discussed through this study in detail. Key words: Solar PV, energy production, performance ratio, specific yield, capacity factor, simulations.'
