The negative effects of global warming resulting from an over-reliance on fossil fuels have been more apparent in recent times. The impending depletion of these resources is a significant threat to humankind's future. Thus, the necessity of creating safe, reliable, and sustainable energy sources is becoming more widely acknowledged. This research developed a solar thermoelectric generator using a plane mirror as a concentrator. The system consists of a plane mirror to concentrate sunlight, a receiver plate, TEG1-241-1.4-1.2 modules, a heat sink, a storage battery, and a power inverter. Temperature across the modules' interface was measured and is used to simulate the performance metric of thermal energy across the module surfaces, power, and efficiency of conversion. The setup yielded a maximum voltage of 13.7 V, a current of 1.8 A, a power output of 15 W, and an efficiency of 8%. The findings underscore the advantages of utilizing thermoelectric modules, particularly in harnessing waste heat. The outcomes of this study contribute to the growing body of knowledge on sustainable energy systems and provide insights for further optimization and implementation.

Keywords: Solar radiation; modules; current; voltage; power; efficiency.
