Consider a 5-kW rooftop PV system that can be installed at a cost of $3000/kW and maintained at a cost of $0.10/kWh. The building is connected to the grid, which provides electricity at $0.10/kWh. Assuming the PV system has a capacity factor of 20%, an annual downtime of 2%, and that the grid does sellback electricity, determine the following based on a life cycle of 20 years and a discount rate of 5%:

a. The LCOE of the PV system.

b. The LCC of the PV system and the baseline (i.e., grid only) system when the average daily electrical load for the building is 75 kWh/day and the power demand is never below 5 kW during daytime throughout the year.
