A university spent $2 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 rst. Approximately how many hours per year will the solar panels need to operate to enable this project to break even? 15,0?9.54 ?,539.?? 13,5?1.59 22,619.31 $199,945.64 _ _ $39,923.90 If the solar panels can operate only for 13,5?2 hours a year at maximum. the pro]ect $219,940. 20 Continue to assume that the solar panels can operate only for 115?). hours a year at maximum. $9302.32 In order for the project to be worthwhile {i.e., at least break even}. the university would need a grant of at least 7
