2. you are considering building a commercial pv solar power system to produce 50,000 kwh of electricity each year. the system will be composed of monocrystalline silicon panels with a cell efficiency of 18.7%. each panel will produce 200 w at full power and costs $175. the balance of system (bos) cost including installation of the panels and the necessary hardware and electrical components (wiring, inverter, and battery bank) and installation is $35,000. the system is estimated to have a capacity factor of 12% and a 25 year life expectancy. assume an operations and maintenance cost of $0.005/kwh. the annual discount rate is 5.5%. a. how many panels are required for the system? b. what is the capital cost (investment cost) of the system ($)? c. what is the annual cost for the fixed capital of the system ($/y)? d. what is the levelized cost of electricity for the pv system ($/kwh)?
