Abstract
Based on actinometric and climatic data obtained from the Guzar weather station (Kashkadarya) and satellite observations, an assessment of the technical potential of solar energy in the Kashkadarya region of the Republic of Uzbekistan was carried out. The indicators of solar photovoltaic power plants were studied in order to determine the forecast indicator of the replacement coefficient of traditional energy resources in the agricultural and irrigation sectors.
Exploratory studies have also been carried out to determine the generation of solar photovoltaic plants installed at various angles of arbitrary orientation
According to the data of the Ministry of Energy of the Republic of Uzbekistan, in the Kashkadarya region today, the actual consumption of electric energy is 891797 and 882174 kWh year (taken together 1773971 kWh year), for agricultural and irrigation facilities, respectively. According to preliminary confirmed calculations, the amount of conventional fuel saved from the use of solar photovoltaic stations to cover 50% of energy consumption (1773971*0.5=886986 kWh year) is 220 tons per year. At the same time, the specific saving of natural gas is 189 thousand Nm3 year, and the reduction of CO2 emissions during the year during the combustion of natural gas is 257 tons of CO2, respectively. It is established that if we take into account that the price of 1 ton of CO2 is estimated at an average of $15, the amount saved in the state budget for the year is $39000, including due to the saving of natural gas $35154 and due to the reduction of CO2 $3855, respectively.
