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 800 kilowatts (KW) and have a life expectancy of 20 years. Suppose that the discount rate is 20%, 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? O' 1,625.74 650.30 O 1,463.17 2,601.18 $95,095.95 If the solar panels can operate only for 1,463 hours a year at maximum, the project break even $190,191.90 $266,268.66 Continue to assume that the solar panels can operate only for 1,463 hours a year at maximum. $152,153.52 In order for the project to be worthwhile (i.e., at least break even), the university would need a grant of at least
