Comparison and assessment of electricity generation capacity for different types of photovoltaic solar plants of 1MW in Sokobanja, Serbia

Abstract

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 mono-crystalline 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.
