Özet

This study investigates the performance of a building integrated photovoltaic/thermal (BIPV/T) system with bifacial and monofacial panels in Sanliurfa’s summer conditions. Experiments were conducted with different fan speeds, air gap distances, and cooling strategies. Results show that bifacial panels achieved 18.19% higher efficiency than monofacial panels and performed better in high temperatures. Increasing the air gap distance has enhanced efficiency, especially in bifacial panels, due to the reflective surface behind the panel. Artificial cooling further boosted efficiency, emphasising its potential for hot climates. It was observed that BIPV/T performance was significantly enhanced through optimised airflow, panel technology, and cooling methods.
