Table 5. Comparison results between the PV system and WT system powered the PEMEL.

Type/item Rated Power Efficiency system The flow rate of hydrogen (mol/s) The flow rate of hydrogen (Nm3/h) Overall system efficiency [(PV or WT system) + (PEM-E130)]
PV system at (1000 W/m2 and 25°C) 7000 16.63% 7.517e-3 0.60655 5.43%
WT system at (12 m/s and zero pitch angle) 12300 57.07% 8.073e-3 0.6514 18.77%
