Photovoltaic-Thermal (PV-T) systems are used to optimize the performance of PV modules in addition to the utilization of the heating fluids for various usages. In the present work, a PV-T system is designed with a serpentine-shaped tube to cool the PV module with water. 3D steady-state analysis was developed, and numerical simulation was performed using ANSYS-Fluent 2020-R2 software. The impact of passing water with different velocities under the PV module is studied. Moreover, the collected results showed that 0.5–0.4 m/s are the optimal values that achieve performance improvement. Finally, the effect of the length of the collector on the electrical efficiency as a design parameter was investigated in this paper. Other parameters can be studied as future contributions.

摘要

Photovoltaic-Thermal (PV-T) systems are used to optimize the performance of PV modules in addition to the utilization of the heating fluids for various usages. In the present work, a PV-T system is designed with a serpentine-shaped tube to cool the PV module with water. 3D steady-state analysis was developed, and numerical simulation was performed using ANSYS-Fluent 2020-R2 software. The impact of passing water with different velocities under the PV module is studied. Moreover, the collected results showed that 0.5–0.4 m/s are the optimal values that achieve performance improvement. Finally, the effect of the length of the collector on the electrical efficiency as a design parameter was investigated in this paper. Other parameters can be studied as future contributions.
