Comparison and assessment of electricity generation capacity for different types of PV solar plants of 1MW in Soko banja, Serbia

Original scientific paper UDC: 621.383.51:697.329 DOI: 10.2298/TSCI110322065P This paper gives the results of the electricity generated by the fixed, one-axis and dual-axis tracking photovoltaic solar plant of 1 MW with flat panels made of monocrystalline silicon which is to be built in the area of Sokobanja (spa in Serbia). Further on follows a description of the functioning of the fixed and one-axis and dual-axis tracking solar plants. For the calculation of the electricity generated by these plants PVGIS program was used. Calculations have shown that fixed photovoltaic solar plant power of 1 MW, solar modules of monocrystalline silicon yield 1130000 kWh power output, one-axis tracking solar plant yields 1420000 kWh, and dual-axis tracking solar plant yields 1450000 kWh of electricity. Electricity generated by the fixed photovoltaic solar plant could satisfy 86% of the annual needs for the electricity of the „Zdravljak“ hotel and the special “Novi stacionar” hospital in Sokobanja.
