For the same PV system characteristics outlined in Problem 9.5, use the LCC analysis method to assess the cost-effectiveness of the PV system compared to the grid-only option (baseline) to constant 800-kWh/day average electrical load throughout the year. Assume the electricity purchased from the grid is at 0.10 kWh, the daytime electrical demand is always below 50 kW, and the grid will not sellback electricity.

Problem 9.5

Consider a 50-kW rooftop PV system installed at a cost of \($3500\)/kW. The PV system operates with a capacity factor of 22%, \($0.005\)/kWh of maintenance costs, and 1% downtime during a typical year. For a lifetime of 20 years and a discount rate of 5%, estimate:
