Abstract

The article provides an overview of the literature sources devoted to the use of solar trackers in pilot operation. It is shown that the efficiency of using uniaxial and biaxial solar trackers depends on the location of experimental solar stations. The article presents a method for calculating the amount of solar insolation received by a photovoltaic panel, taking into account the sky clarity index. The technique makes it possible to take into account the angle of the surface position of solar photovoltaic panels relative to the horizontal surface of the Earth at any given time (with an accuracy of seconds) throughout the year. A mathematical model is proposed for determining the index and payback period of solar power plants equipped with solar tracking systems with an accuracy of up to a year. A mathematical model has been developed for calculating the power consumption for rotating platforms with solar photovoltaic panels using trackers based on the angle of declination and azimuth of the Sun. The effectiveness of the use of solar tracking systems for various regions of the South, Volga region, Urals, Siberia and the Russian Far East has been evaluated. The calculations were performed taking into account real hourly meteorological data over the past five years (2019–2023). The calculation results showed that the efficiency of the solar tracker throughout Russia is very significant. The increase in electricity generated by a solar station equipped with a two-axis solar tracker ranges from 24 to 40 %. According to the developed methodology based on the example of Technical and economic calculations were carried out in Orenburg, which showed that it is most economically feasible to use uniaxial trackers in this region. Calculations show that the use of single- coordinate azimuthal and dual- coordinate solar tracking systems can reduce the payback period of a solar power plant
