Abstract

In this paper, a simple pass photovoltaic-thermal air heater system with slats has been considered to study its electrical and exergy performance by theoretical and numerical analysis. The collector has been modeled in such a way that the absorber plate is totally covered by photovoltaic modules. The climatic data (solar irradiation, ambient temperature) of the Far Nord region of Cameroon have been used. Thin metallic strips called slats have been attached longitudinally at the bottom side of the absorber plate of the system. The first and second laws of thermodynamics have been applied to write the equations describing the functioning of the system. These equations have been solved by numerical computation using the gradient conjugate method. The influences of some operating parameters on the electrical and overall exergy efficiencies were investigated. It was found that (i) it is of great importance to use slats as an integral part of the absorber surface in order to achieve better efficiencies of single pass photovoltaic-thermal systems and (ii) the instantaneous overall electrical and overall exergy efficiencies of a simple pass hybrid (PV/T) solar air heater varies between 9-12% and 11,5-18,5% respectively.
