Efficiency gains include a thermal efficiency of 52.88% and a 1.66% electrical efficiency improvement.
Using computational fluid dynamics simulations, we modeled systems with airflow rates of 0.02 kg/s to optimize performance.
The low‐flow PV/T system design reduces fan power by 50%–70%, enhancing exergy efficiency significantly.
Findings support the application in high‐irradiance regions, such as the Middle East and North Africa, while addressing environmental impact.
