This article examines hybrid energy systems integrating thermoelectric generators and solar photovoltaic installations. An analysis of the operating principles and efficiency of such systems is carried out, and the possibilities of increasing electricity generation through the utilization of thermal energy generated during the heating of solar panels are investigated. The main factors affecting the performance of the hybrid system, including solar radiation intensity, temperature conditions, and the characteristics of thermoelectric materials, are considered. The obtained results demonstrate that the combined use of thermoelectric generators and photovoltaic modules contributes to an increase in the overall efficiency of the system and ensures more effective utilization of renewable energy sources.
