Abstract
There are many models for determining the theoretical productivity of PV panels, based on weather data and data characterizing PV panels. The main target of this study to contribute the similar studies for Polish conditions for photovoltaic microinstallations. The study analyzed the compliance of weather data from the ERA5 database with the measurement (pyranometer on horizontal surface) on PV installation site. Comparative studies of insolation from the ERA5 model with measurements made with a pyranometer were carried out for 1187 days. Higher values for daily insolation values were observed in most day cases (85 %) for data from ERA5 than from the measuring station. The value of relative mean bias error (rMBE) was 23 %.The second part of the research concerned the verification of the computational model of PV energy production based on the data of photovoltaic panels, configuration of settings and locations as well as ERA5. The differences between the results from the model and the real measurements from the rMBE installation for the first year of operation are 8 % and for the second 0 %.
