6. Individual Problems 5-4 A university spent $1.7 million to install solar panels atop a parking garage. These panels will have a capacity of 400 kilowatts (KW) and have a life expectancy of 20 years. Suppose that the discount rate is 30%, that electricity can be purchased at $0.10 per kilowatt-hour (KWh), and that the marginal cost of electricity production using the solar panels is zero. Hint: It may be easier to think of the present value of operating the solar panels for 1 hour per year first. Approximately how many hours per year will the solar panels need to operate to enable this project to break even? O 12,817.61 O 7,690.57 14,099.37 16,662.89 If the solar panels can operate only for 11,536 hours a year at maximum, the project break even
