Abstract
Nowadays, after the fourth industrial revolution, our economy has become very dependent on energy. The depletion of fossil resources is therefore a major concern. So, to be able to substitute our needs by renewable resources, we must pay more attention to the development of the latter. Among the most intrinsic problems that reduce the efficiency of photovoltaic (PV) panels is the operating temperature, due to the large amount of absorbed radiation that turns into heat, therefore, in this paper, an investigation of two types of fins for cooling the photovoltaic panel has been carried out. A comparison was made between the two systems as well as a study of the effect of lapping size on the cooling system. The proposed system is simple and suitable for integration. To be more realistic, a user-defined function UDF subroutine written in C+ + has been developed to integrate the unsteady evolution of the climatic conditions of a summer day in the city of Oujda (eastern Morocco). The computational fluid dynamics (CFD) investigation has revealed that the use of simple fins can reduce the average temperature of the panel by 18.16 °K, while when lapping fins are used, the temperature reduction was decreased by a value of 23.7 °K. Thus, it was found that the temperature of the PV panel decreases as the lapping height increases, according to the study of the three cases taken 0.003 m, 0.007 m, and 0.01 m.
