Energy consumption is rapidly increasing with advancing technology. For this reason, solar energy from one of the renewable energy sources should be laid on. Because it can produce electrical energy, such as solar energy, photovoltaic conversion could also be utilized as a source of direct heat. Photovoltaic energy from sunlight most of the systems, the modules are collected by means of, converted to chemical energy for use at night and on cloudy days the battery is collected. In this study, using solar energy, energy derived from the sun through solar thermoelectric cooling is used. Thermoelectric cooling (TEC) effect on the coefficient of performance (COP) was evaluated. For this purpose, the TEC system with power supply and the PV operated separately. PV system is fed with a battery operated on cloudy days and at night. COP value were calculated from the temperature values collected by data logger certain points. COP value was found on TEC system operated with power supply and PV. In this study, COP values of PV for the case where the highest levels of solar radiation was observed to be better than COP values for the power supply is constant, has been rising in specific proportions. Given that both of these systems working hours was observed to be better value than the PV system.
