Increasing The Efficiency of The Solar Panel Using Thermoelectric Module

Abstract

Performance of solar panel decreases with increase in the temperature of the panel. Output power of PV module drops by 0.45% per oC rise in temperature if heat is not removed. Cooling of the modules would enhance the performance of the module. To cool this system thermoelectric system is developed. Thermoelectric module is attached at the back of PV module, and it is operated in cooling mode. The role of TEC is to reduce the temperature of the PV cells, to increase the efficiency of the system, its power capacity and lifetime. The use of thermoelectric devices based on silicon material results in increasing efficiency of PV system of 3.6% with a maximum efficiency of 13.06%.
