Research of changes in the efficiency of renewable energy depending on external influences

Abstract

Abstract The article presents the results of a study of renewable energy sources (RES) based on solar panels, the operation of which took place in the Irkutsk region. The results of changing the efficiency of the solar panels depending on the use of light energy concentrators and the temperature of the panel itself are presented. The authors set the task of increasing the efficiency of the solar panels through the use of technical and constructive solutions.The experiments were carried out in the laboratory of IRNITU “Modern Heating Equipment”. For testing, we used a bench based on the TPM138 measuring regulator, an OVEN device of the IMS-F1.SH1 brand with a set of thermocouples., The subject of the study was two solar panels, on one of which a Fresnel lens was installed.The article formulates the purpose and objectives of the study, conducted research on the parameters of solar panels depending on the influence of the light energy concentrator and temperature changes on the panel itself, depending on external influences.As a result of the work, it was found that the efficiency of solar panels in the Irkutsk region in the summer period of time decreases by an average of 14.5%. And in the winter time by 7.5%. It is shown that to increase the efficiency of solar panels it is necessary to apply technical and constructive solutions that will reduce the payback period of solar engineering systems by 10-18%.
