6. Individual Problems 54 A university spent $1.3 million to install solar panels atop a parking garage. These panels will have a oapacity of 300 kilowatts [kw] and have a life expectancy of 20 years. Suppose that the discount rate is 30%, that electricity can be purchased at $0.20 per kilowatthour (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 operang 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? 0 3,26?.16 0 3,494.50 0 5,880.88 O 5,534.31 If the solar panels can operate only for 5,381 hours a year at maximum, the project V break even. Continue to assume that die solar panels can operate only for 5,381 hours a year at maximum. In order for the project to be worthwhile (i.e., at least break even), the university would need a grant of at least 7
