Today, the use of thermoelectric generators (TEGs) in various experimental applications is increasing rapidly. Thermoelectric generators are generally preferred in places where there is waste heat. In this study, open circuit voltage was generated by thermal conversion as a result of concentrating solar energy from the solar thermoelectric generator (STEG). Two different Fresnel lenses, linear and spot, were used for solar concentration. In addition, a selectively surface-coated copper plate was preferred to increase the thermal values. In addition, to take full advantage of the sun’s irradiance, the manufactured system was adapted to a dual-axis solar tracking system, enabling the system to follow the sun throughout the measurement period. It has been observed that the experimental values of parameters such as open circuit voltage, hot side temperature, and cold side temperature of the TEG module change with solar irradiation. While the maximum open circuit voltage value for the selective surface-coated system was 0.35 V, this value was obtained as 0.24 V for the system without selective surface coating for the sides where the spot-type Fresnel lens was located. The study also includes a numerical model for the TEG system with the heat sink. The model’s outputs were validated in terms of open circuit voltage and cold side temperature. The electricity generation potential of the system under operating conditions other than the experimental study was demonstrated.
