Solar power offers a chance to decrease dependence on imported fossil fuels, a crucial consideration for nations heavily reliant on energy imports. Hybrid nanoparticles have been used for PV cooling to enhance the efficiency and perfor-mance of solar panels. This study investigates the use of nanofluids to improve power production, lifespan, and effi-ciency. Three photovoltaic panels with different cooling meth-ods were tested in this study. The effect of a 2 wt % Al2O3/ZnO hybrid nanofluid was assessed at flow speeds ranging from 1 to 3 liters per minute. Three panels, PV-1, PV-2, and PV-3, are used in this experiment. A 2 wt % hybrid nanofluid of Al2O3/ZnO is used to study the first solar panel (PV-1), often known as PV-one. The second solar panel (PV-2), called PV-two, is cooled using forced air and a 2 wt % hybrid nanofluid of Al2O3/ZnO. In contrast, PV-three, the third panel (PV-3), had no cooling. When an Al2O3/ZnO hybrid nanofluid with forced air was used, the electrical energy efficiency increased the most, at 17.9 %. Additionally, using a hybrid nanofluid of Al2O3/ZnO produced a 17.5 % outcome, whereas an uncooled panel produced a 15.1 % result. In contrast to the hybrid nanofluid, which had a temperature of about 9.4 °C, the hybrid nanofluid with forced air had a temperature increase of 9.8 °C. Compared to the uncooled panels, this resulted in an 11.2 % increase in output power. The maximum output powers for cooling with hybrid nanofluid with forced air, hybrid nanofluid, and uncooled panels were 45.6, 44.1, and 40.2 W, respectively. Additionally, the CFD was used to evaluate the serpentine pipe thermal performance.
