The Photovoltaic/Trombe wall system (PV/TW) is a design that generates electricity and provides hot air and warm water for domestic uses simultaneously; this system aims to optimize the electrical efficiency of the PV panel by removing the heat from them. The current article includes a study of the impact of utilizing reflective mirrors on the performance of PV/Trombe wall. Reflective mirrors were used to increase the quantity of solar energy reflected on the solar cells. Fans were also utilized to lower the heat of the PV panel and optimization comfort conditions. The results showed that using reflecting mirrors and DC fans led to the optimization of electrical and thermic efficiency. The maximum thermal efficiency value recorded was 74.4% when using reflective mirrors only without fans. In contrast, the highest electrical efficiency in the case of using DC fans without reflective mirrors was 13.9% at noon. These results are in convention with those of prior studies.
