ANALYSIS OF THE ENERGY INDICATORS OF THE 70 kW PHOTOELECTRIC STATION CONNECTED TO THE ELECTRIC NETWORK UDC 621.383.51
Abstract
In the article, the one-year monitoring results of the 70kW on-grid solar station (SS) in the city of Termez, located in the southernmost part of Uzbekistan, are presented. Annual, monthly and daily energy production graphs were analyzed and it was determined that the annual energy production amount is 62.77MWh. Through calculations, the values of the installed coefficient utilization factor (ICUF) were calculated for the solar station and its annual and monthly average values were found. Even though the average ICUF is 10.32%, the on-grid solar station can be considered a promising project. The biggest factor causing system energy losses is pollution, which is related to the climate of the region. The main factor in the sharp difference in the results is the stationarity of our station and the fact that the technique of cleaning the panel's surface from pollination was not used. However, the payback period of such a station by calculation included 7.5 years if inflation is not taken into account.
