A thermoelectric generator is a solid-state temperature dependent device that provide power generation on thermoelectric conversion. For that, the thermoelectric modules needs a temperature difference to ensure the thermoelectric conversion process. However, being subject to temperature variations may compromise the thermoelectric generator lifetime. Thus, in order to evaluate the temperature variation (thermal cycling) that the thermoelectric generators are exposed, this work has proposed an experimental platform that submits the thermoelectric generators modules to thermal cycling. With the experimental platform proposed the parameters of the thermoelectric generators may be to investigate properly. To evaluate the degradation effects on TEG the parameters were evaluated before the thermal cycling and then the parameters were evaluated after the thermal cycling process. At the research end, the parameters are presented by a comparative table with parameters evaluation before the thermal cycling and parameters evaluation after thermal cycling which brings to the experimental platform reliability.
