The electrical performance of a photovoltaic (PV) module is hugely affected by its tempera-ture. This study proposed a passive cooling mechanism for the cooling of a PV panel. The proposed cooling system is made up of a combination of aluminum fins and paraffin wax integrated at the PV panel’s rear side. The average temperature for the cooled panel for the entire period of the experiment is 36.62◦C against 48.75◦C for the referenced PV module. This represents an average reduction of 12.13◦C for the cooled panel. The average power for the cooled panel is 12.19 W against 10.95 W for the referenced module which is 11.33% improvement. The electrical efficiencies for the cooled panel and the referenced modules are 14.30% and 13.60%, respectively, representing an improvement of 5.15% in the electrical efficiency. The cooled solar PV module had an average exergy efficiency of 7.99% compared to 5.61% for the referenced module. In terms of the economics, the results from the computations show that LCOE of the cooled panel can range between 0.198 and 0.603 $/kWh, while that of the referenced module ranges from 0.221–0.671 $/kWh depending on the number of days it operates. © 2021 by the authors.
