To the Issue of Increasing the Energy Efficiency of Photovoltaic Installations

The paper provides a review of the scientific and technical literature, statistics in the field of solar energy, the reasons for the rapid development of photovoltaics and ways to increase the energy efficiency of photovoltaic installations. The most effective way to increase the efficiency of solar power plants is to use solar tracking systems (trackers). The article describes the photovoltaic installation consisting of a stationary photovoltaic module and a photovoltaic module with a dual-axis solar tracker. The results of testing the photovoltaic installation are presented. Testing of the installation has been carried out on the territory of Orenburg State University. The use of the solar module with a dual-axis tracking system in June 2019 has led to an increase in electricity generation by 36.1% (compared to generating electricity using a solar module that is oriented south at a fixed angle).
