Abstract

A thermal model regarding a photovoltaic module has been developed and validated using experimental data. The aim of this study was to recovering heat wasted by Joule effect by adding the heat exchanger rear sensor and an additional window forward. We will also compare the thermal and electric performance a hybrid sensor covered with an additional pane with another uncovered in the aim of improving the efficiency of the sensor and the influence of air flows and then we will study the effect of the thermal conductivity of the metallic absorber on the most optimal system performance. The results showed that key design parameters such as the heat flux captured, air flows, and the thermal conductivity of the solid absorber had a significant influence on both the electrical and thermal efficiency of the hybrid sensor.
