Objective of the thesis is to present the working principle of the solar powered thermoelectric cooling system, the development of concepts and prototype making of that cooling system. From three made concepts we took the main ideas and constructed two prototypes. In the thesis we measured the temperature with Ahloborn Almemo 2690-8 data logger's thermocouples which I have placed on different spots of the cooling system. With results of measurements we calculated coefficient of performance of the prototype and then compared the results with the conventional cooling systems, I concluded that in my case, where prototype of solar powered thermoelectric liquid cooling system was made with waste material found in the research laboratory. It is not worthwhile yet.
