The effect of increasing solar cell temperature due to excessive solar radiation exceeds the limit causes a decrease in the efficiency of the PV panel. Experimental research has been developed to study the effect of a cooling technique with a passive cooling method which has free convection heat transfer to photovoltaic using perforated aluminum plates. The result of this research is an increase in the efficiency of PV panels using perforated aluminum plates by 10.02%.
