In this papier we studied the integration of thermoelectric cooling devices (TEC) in photovoltaic (PV) generators to constitute PV-TEC systems to improve the performance of the system. The efficiency of photovoltaic panels is undesirably influenced by the increase in temperature, which reduces the current draw of the photovoltaic cells. For this, the role of the Peltier Modules is to reduce the temperature of the PV cells, to increase the efficiency of the system, its power capacity, and its lifespan. The system is based on an Arduino microcontroller as the main control unit. The panel temperature is cooled by a Peltier plate. A sensor is used as a temperature sensing device and sends feedback to the microcontroller regarding the current temperature of the PV. All components are connected to analog circuits to form a closed loop feedback controller to dynamically control the temperature of the PV.

摘要

In this papier we studied the integration of thermoelectric cooling devices (TEC) in photovoltaic (PV) generators to constitute PV-TEC systems to improve the performance of the system. The efficiency of photovoltaic panels is undesirably influenced by the increase in temperature, which reduces the current draw of the photovoltaic cells. For this, the role of the Peltier Modules is to reduce the temperature of the PV cells, to increase the efficiency of the system, its power capacity, and its lifespan. The system is based on an Arduino microcontroller as the main control unit. The panel temperature is cooled by a Peltier plate. A sensor is used as a temperature sensing device and sends feedback to the microcontroller regarding the current temperature of the PV. All components are connected to analog circuits to form a closed loop feedback controller to dynamically control the temperature of the PV.
