The Impact of Selected Parameters on the efficiency of PV Installations - Simulation Test of the 1 MW PV Farm in the PVSyst Program

Nowadays, more and more solar farms are being created in Poland. This is due to the development of PV technology, the appearance of more efficient systems on the market, but also the need for Poland to achieve a 50% share of energy production from zero-emission sources. In designing PV farms, an important issue is the selection of the right angle, but also the distance between individual rows of panels. The article shows the work analysis of the 1 MW PV farm consisting of 2000 units of 500 Wp panels with dimensions of 2220 mm x 1108 mm x 40 mm and a weight of 28.60 kg and 8 inverters SUN2000-105KTL-H1. The panels are arranged in 10 rows in two directions: south and south-west. The analysis was performed for the angles of 10°, 20°, 25° and 30°. The investigation was carried out in order to evaluate the effect of changing the angle of the panels and the distance between the rows on the PV farm efficiency.
