Calculate the size of a solar photovoltaic farm with a daily 1 MW power, operating for an average of 10 hours daily. Use a solar panel measuring 1m x 2m with 20% overall efficiency. The solar irradiance in the farm is about 300 Wh/m2.
Assume the output of this farm is used to produce hydrogen from the electrolysis of water. Calculate the volume of hydrogen (in cubic meters) that can be produced at 500 atmospheres. Assume 90% efficiency for the electrolysis cells.
