Kwame Nkrumah University of Cape Coast, Legon spent GHS1.8 million to install solar panels atop a parking garage. These panels will have a capacity of 500 kw, have a life expectancy of 20 years and suppose the discount rate is 10%. a. If electricity can be purchased for costs of GHS0.10 per kwh, how many hours per year will the solar panels have to operate to make this project break even? b. If efficient systems operate for 2,400 hours per year, would the project break even? c. The university is seeking a grant to cover capital costs. How big of a grant would make this project worthwhile (to the university)?

The US government offers Treasury bonds which will pay $10,000 in 5 years time. If the market interest rate is 3%, what would be the most an investor would pay for the bond today? $8,626 $11,131 $5,872 $12,141 $7,245

A family is considering whether to invest in solar panels. Some information regarding solar systems and energy in general has been gathered in their home and is summarized below. The average cost for residential energy is S0.124/kWh o The government subsidizes 70% of whatever is invested by the household o Each square foot of panel produces 19.13 kWh every year The cost of installation per square foot of solar panel is $93.91 The family house has 350 square feet of roof space. Answer the following questions for each of these interest rates: 1.5%, 3%, 6%, and 12%. Provide a complete solution including code snippets utilized in the solution in the write-up submitted [as screenshots]. a) Draw a cash flow profile for this problem and indicate the type of project this profile maps to.
