Abstract

The paper presents a classification of solar tracking systems used in photovoltaic power stations (PVS) and
their operating principles. A simulation model of a grid-connected 5-kW PVS has been developed in PVsyst, to
which end the researchers selected PVS equipment and optimized the PV cell tilt angles. The paper further analyzes a grid-connected PVS in Orenburg Oblast in PVsyst under the following configurations: static PV cells,
not tilted vs seasonally varied tilts; single-axis solar trackers with vertical and horizontal axes of rotation vs a dual-axis solar tracker. The analysis is based on solar insolation data for 2019 obtained from the research
team’s HP-2000 weather station. Dual-axis solar tracker and single-axis vertical trackers are shown to have
the best year-round generation, providing an increase of 13.2% and 11.5%, respectively, against the static PV
cells (no change in tilt).
Keywords: solar trackers, RES in Orenburg Oblast, PV power stations in Orenburg Oblast, Solar tracking

systems, PVS equipment selection.
