Experimental Data The effect of varying configuration of fins on PV/T efficiency at various airflow

In this experimental study, the cooling system is in the form of aluminum fins which are attached to the lower side of the PV/T. To evaluate the effect of the number of fins to PV/T efficiency, four PV/T configurations were used, 1 PV/T without fin as the reference, and the other 3 PV/T attached with several fins, i.e. 8, 16, and 24 pieces. To evaluate the efficiency of the PV/T, measurement for each configuration was carried out at 3 airflow rates, 1.85 m/s, 2.2 m/s, and 2.55 m/s
