1.Determine the cumulative electrical energy produced in kW-hr
2. Determine the fraction of energy produced compared with the sunny day
from the example problem.
3. An electrolysis unit operates at 60% efficiency. If the theoretical amount of
energy needed to convert 1 mol of liquid water into 1 mol of hydrogen and
½ mol of oxygen is 285 kJ, determine the mass of hydrogen produced in g
for one day.
4. If each solar panel has area of 70” x 40”, determine the number of panels
and solar surface area in ft2 required to supply 1 kg of hydrogen on cloudy
days.
