Etude et modélisation d’un panneau solaire thermique photovoltaïque.

Abstract

The objective of this work is the theoretical study of thermal photovoltaic solar collectors with cylindro-parabolic concentrator and heat exchanger to increase the efficiency of the cylindrical system and cools the solar panels and heat the heat transfer fluid. In this work, we have established two distinct models: the first uses air as heat transfer fluid and the second uses water as coolant. Both models make it possible to calculate the average temperature of the fluid and the photovoltaic cells as well as the efficiency of the system, with a modification of the external and internal factors such as the flow and the height of the air channel for the air and the hydraulic diameter for the water. The results obtained allow us to know the effects of the external parameters on the efficiency of the system and to determine the characteristics of each system, the results are satisfactory and published in well indexed scientific journals.
