Abstract
Relevance In conditions of elevated ambient temperatures, a solar battery operating at temperatures above 40 °C reduces the output power by –0.45 % / °C. In the conditions of an isolated hybrid power supply system, this fact can lead to a significant loss of power in the network from heating solar cells and costs, since an additional source of power supply as part of Hybrid Renewable Energy Systems (HRES) is a diesel power plant. Aim of research The main aim of the research to investigate the effect of elevated ambient temperatures and reduced temperature of thermoelectric elements on the solar panel in the MatLAB Simulink environment, to calculate the approximate energy efficiency from the method used as part of hybrid power supply systems based on renewable energy sources (HRES). Research methods As a mathematical model, it is proposed to use the MatLAB Simulink complex, as a device for reducing the temperature of the solar module, it is proposed to use thermoelectric elements. Results Based on mathematical calculations in the MatLAB Simulink environment, with the help of thermoelectric elements, it was possible to increase the maximum power by 0.11 kW, which, according to approximate calculations, will save the equivalent of diesel fuel in the amount of 267,000 rubles in the period from April to September for the village of Kuskurgul with a consumption of 100 kW.
