Abstract
The operating temperature of the PV penal has a significant impact on its conversion efficiency. High operating temperature reduce output power under the same solar radiation conditions. This study presents a CFD analysis of a solar PV/T system with a bottom active air cooling system to optimise the PV/T system operational characteristics. The study model was developed using fluent (ANSYS) software, along with bottom air duct with an inlet/outlet manifold for uniform airflow to the back side of the PV/T system. The performance of operating parameters of PV/T system was studied for various mass flow rates of air such as 0.04, 0.06, 0.08, and 0.1 kg/sec with irradiance intensity of 800 W/m2. The maximum temperature of the operational parameters such as the Solar PV/T system top surface, cell, bottom surface, and air inlet/outlet of the PV/T system were determined to be 48.8, 48.4, 47.3, and 24.5 °C at a flow rate of air of 0.01 kg/s and 800 W/m2 intensity of solar radiation.
