Assessment of influence of climate conditions on the efficiency of operation of a solar photoelectric installation

The influence of climatic conditions of the area on the efficiency of a solar photovoltaic installation with a power of 400 W in real conditions of Khujand city of the Republic of Tajikistan has been studied. Based on the results of temperature monitoring of photovoltaic module and the air of the area, an assessment has been made of the decrease in electricity generation from the solar photovoltaic installation due to cloudiness and high temperatures of photovoltaic module and the air of the area. It has been shown that the minimum values of the efficiency correspond to the maximum temperature of the photovoltaic module at noon. The average daily efficiency of photovoltaic module is 0.15 (15%) in the summer and 0.2 (20%) in the winter months. (author)
