The temperature of a photovoltaic (PV) panel has a detrimental impact on the electricity output. The operating temperature of the PV increases as the amount of solar irradiation falling on the solar panel increases. As a result, energy efficiency suffers. In order to keep PV temperatures as low as possible, a cooling system is required. This research has adopted a passive cooling strategy using Titanium oxide-coated L-shaped aluminum fins attached to the backside of the PV at different spacings. Five identical PV modules have been installed side by side. One has been used as a base module for comparison purposes. The backside of each of the other four fins has been attached at a fixed spacing and coated with a specific concentration of water-based TiO2 nanofluid. The hourly average temperature of each module has been measured using three K-type thermocouples attached to its backside. The current and the produced power from each PV have been estimated using load resistors. Finally, the ambient temperature and the solar radiation values have been measured using the GRWS100 weather station located on the site. The passive cooling strategy using natural convection has significantly reduced the temperature at the backside of the PV modules, according to the findings. The highest significant power improvement has been roughly 9 W when using a 2 cm spacing between the fins and a 0.04% TiO2 concentration. PV panels with 2 cm spacing and 0.04% TiOFTiP fin cooling boosted their efficiency by roughly 1.72%.
