In fuel cell-PV solutions, fuel cells act as back-up, supplementary and even take over power generation when solar cells fails, during nights and in areas, challenged by the cycling of monsoons.
At Advent, we have a customer example of such a hybrid with partner ALCC (click here to see case). The hybrid consists of fuel cells and solar panels where the system operates at night after the sun sets, cools down when the sun rises, and re-starts charging on the solar batteries. During the 6-8 weeks monsoon season, the fuel cells generate power more than 24 or 48 hours continuous. In the given example, 4 x 1000 l IBC tanks, provides around 900 hours of fuel-cell run-time and 4,400 kWh.
