Abstract

Nowadays, photovoltaic (PV) panels are known as effective devices for harnessing solar energy to create healthier and more environmentally friendly energy. However, the operating temperature of a PV system has a significant impact on its efficiency. In this study, a twisted tape was inserted inside a rectangular channel with different values of hybrid nanofluid (1, 2, and 3%) as a coolant fluid to cool the photovoltaic panel for improved efficiency. To stop PV panels from getting too hot, the Ansys Fluent program was used to numerically design a hybrid nanofluid cooling system with 20% MgO and 80% CuO in water as the base fluid. The nanofluids were mixed in different amounts and suspended in water. The impacts of solar radiation (500, 800 and 1,000 W/m2), and Reynolds numbers on efficiencies were studied. As a result, the average surface temperature (T cell) dropped from 29.16 to 25.87 and the electrical efficiency of the PV modules went up from 11.77% to 11.95% when a 31.25 mm pitch of the twisted tape insert was used inside the rectangular channel at 1,000 W/m2 of solar radiation. In comparison to a conventional smooth channel, the improved channel significantly lowered the average temperature of the cell by 3.29 °C.
