Abstract Photovoltaic (PV) systems are an excellent solution to meet energy demand and protect the global environment in many cases. With increasing utilization of PV system worldwide, there is need for simulation tools predict system’s performance profitability. This research includes testing comparison tools: photovoltaic geographical information (PVGIS), PVWatts, SolarGIS, RETScreen, BlueSol, PVsyst, HelioScope, PV*SOL, Solarius PV, Solar Pro, F-Chart, PolySun, solar advisor model (SAM),...
This study analyzes the grid-connected PV system performances over a 10-year period under temperate continental conditions in Niš. Based on experimental results, we found following: yearly average values of efficiency, Yf, CF, and PR are 10.49%, 1178.51 kWh/kWp, 13.45%, 0.87, respectively. The value for measurement indicates that behavior given 10 years does not change significantly. Besides, mathematical prediction model was obtained through regression analysis, ANOVA applied testing...
