Techno-economic analysis of PV/H2 systems

The results show that regardless of setpoint power, the optimum system design fits the ratios: installed PV power-to-setpoint power = 2.4-2.5; nominal electrolyzer power-to-setpoint power = 0.72-0.75; nominal fuel cell power-to-setpoint power = 1. We also found that the capacity of the H2 tanks corresponds to around 48-50 days of off-grid power (number of days where setpoint power comes exclusively from the fuel cells).
