Thermal and Electrical Performance Analysis of PV/Trombe Wall System

This paper presents a theoretical and experimental study of the performance of a PV-Trombe wall (PV-TW) system with and without DC fan under Iraqi weather conditions. A theoretical model was developed based on an energy balance concept and an experimental setup was built up for system performance analysis. The validation shows well matching between theoretical and experimental data. The results reveal that the presence of DC fan increases the indoor temperature significantly for the tested PV-TW system. Furthermore, there is an improvement in the electrical performance of this system, where its electrical efficiency reaches up to 12%. Accordingly, the existence of the DC fan able to enhance the indoor comfort condition and to cool the PV cell. This potential of the PV-TW system is extractable based on the tested conditions.
