This paper analyzes and compares the actual measured and simulated performance of a 454 kWp grid-connected photovoltaic system installed on the rooftop of the university building. The data presented in this study were measured from June 2018 till June 2020. The annual production in 2019 was 375MWh. The performance of the system was simulated using PVsyst software. Surprisingly, simulation results somehow predicts the yield similar to the actual field performance in 2019, despite the unpredicted Nordic climatic conditions and other systematic errors from inverters and shadows. The PV panel orientation have positive impact on the performance enhancement during long sun hours.
