ANALYSIS OF THE ENERGY INDICATORS OF THE 70 kW PHOTOELECTRIC STATION CONNECTED TO THE ELECTRIC NETWORK
Keywords:
on-grid system, solar station, installed coefficient utilization factor, yield energy, renewable energy, efficiency, pollution.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.
