Finned PV Natural Cooling Using Water-Based TiO2 Nanofluid

The efficiency of PV (photovoltaic) modules is highly dependent on the operating temperature. objective this work to enhance performance by passive cooling using aluminum fins that have been nanocoated (like those an automobile radiator). A rise in cell temperature module leads a decrease its performance. As result, effective mechanism required. In work, has improved natural convection, which was achieved placing three similar next each other order test them simultaneously. first panel will be base and used for comparison purposes. An automotive radiator (with fins) firmly fixed onto rear two modules, third had titanium oxide (TiO2) water-based nanofluid applied them. power produced as well their side temperatures, were recorded every 30 min over four months. reduction 4.0 °C attained when TiO2 sprayed panel’s finned side. This followed scenario where only finned, with drop 1.0 °C. result reduction, percentage coated-finned increased 5.8 1.5 percent, respectively. caused increase 1.1 percent panels 0.4 PV.
