conducting an experimental approach to improve the production of photovoltaic (PV) modules is important to raise the efficiency of the solar power system. Within the framework of this paper, the possibility of increasing the production of solar panels and optimizing their operation is considered by different conditions like irradiation, angle of incidence of light rays, temperature and load. In the Theoretical Electricity Laboratory at the Higher Voltage School, Institute of Energy, Peter the Great St. Petersburg Polytechnic University, several experiments were conducted on the laboratory solar station device (GalSen- NEE4-MFESE-N-R), which simulates the solar system as a model of a photovoltaic solar power plant.
