Evaluating the performance of photovoltaic simulation tools: case study of grid-connected 31 kWp photovoltaic system

Two widely used commercial tools, PV*SOL and PVSyst, are used for simulation of 31 kWp grid-connected rooftop photovoltaic system installed on the Faculty of Electrical Engineering, Mechanical Engineering and Naval Architecture in Split. The analysis covers five-year period from 2017 to 2021 for which the meteorological data has been obtained from Croatian Meteorological and Hydrological Service. The simulation results are compared with the measured data of electricity production on a daily, monthly and annual basis.
