Attempts Average / 3 4. Individual Problems 5-4 A university spent $1.9 million to install solar panels atop a parking garage. These panels will have a capacity of 700 kilowatts (KW) and have a life expectancy of 20 years. Suppose that the discount rate is 30%, that electricity can be purchased at $0.30 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? 1,910.04 iz!] O 4,365.81 O 2,728.63 $75,935.23 If the solar panels can operate only for 2,456 hours a year at maximum, the project $246,789.50 break even $189,838.08 Continue to assume that the solar panels can operate only for 2,456 hours a year at maximum. $208,821.89 In order for the project to be worthwhile (i.e., at least break even), the university would need a grant of at least
