Currently, the most promising source of energy is the energy of the Sun.
The purpose of the study was to establish the dependence of the power generated by the element of the solar photoelectric converter (SPС) on the angle of incidence of the sun's rays.
The scientific novelty consists in substantiating the effectiveness of using SPС positioning systems relative to the sun to increase the efficiency of converting solar energy into electrical energy.
A study was conducted of three types of silicon SPC of the same manufacturer of the same power, which were located at the same angle in cloudy weather. It was established that the single-crystal SPC generates more power than other types of SPC. The influence of the angle between the sun's rays and the surface of the SPC on the generated power was investigated. It was established that the most effective operation of the SPC occurs when the module is fully illuminated and the sun's rays fall perpendicularly on the module. The data obtained were analyzed and it was established that for the effective operation of the SPC there is no need for constant movement of the tracker following the Sun, since it is sufficient to turn the tracker by 20° in the direction of rotation The sun in the case of leaving the zone in which the power produced by the SPC is unchanged.
The operating curves of the graphs are used to determine the parameters that will provide effective control of the SPС position, which will help operators or technicians to select the optimal position of the SPС depending on the position of the sun. The obtained results can be used for all SPСs of the single-crystal type.
Key words: solar photovoltaic converter (SPC), solar tracker, electrical safety, solar energy, alternative energy sources
