Enhancement study of the efficiency of photovoltaic panels through the utilization of geothermal cooling system

Abstract

In this work, we present an experimental study to improve the efficiency of photovoltaic panels through the use of a geothermal cooling system. In this pilot study, the geothermal cooling system was attached to the back of the PV panel using an aluminum cover that allowed a gap for a irflow flowing from the underground pipe. The results obtained showed that the temperature of the cooled panel decreased by 6°C compared to the temperature of the non-cooled panel. We also found that the faster the airflow, the faster the PV panel cools. We can consider geothermal cooling system as one of the solutions to the problem of photovoltaic cell overheating
