A university spent 1.8 million to install solar panels atop a parking garage. These panels will have a capacity of 500kw, with a life expectancy of 20yrs and suppose the discount rate is 10% a. If electricity can be purchased for cost of $0.10 per kwh, how many hour per yr. will the solar panels have to operate to make this project break even. b. If efficient systems operate for 2,400 hrs pr year, would the project break evens? c. The univ. is seeking a grant to cover capital costs. How big of a grant would make this project worthwhile (to the university)?
