Experimental performance of concentrating photovoltaic thermal module

A concentrating photovoltaic thermal system is composed of multiple concentrator modules which designed with wide acceptance angle such (Hyperbolic Profile) to collect high illumination flux that can be used for building integrated applications, in order to produce electrical and thermal energy, as well as to reduce gained solar radiation of the sun and enhancing natural day lighting in buildings. In this study many stages have been taken into consideration to achieve the optimum design. The system has been divided into two sections, first section is consisted of PMMA configured with Longitudinal Aluminum Plates and second section is considered as one piece of Flat Aluminum Plate. The results of the comparison between two sections with constant flow rate regarding temperature difference at the section of Flat Aluminum Plate is slightly higher than that in the section of PMMA plus Longitudinal Aluminum Plates.
