If the company uses a discount rate of 12%, what is the net present value of this project? (Round your answer to the nearest whole dollar. Use parentheses or a minus sign for a negative net present value.) The net present value of the project is Requirements 1. Calculate the payback period in years of the solar panel project. 2. If the company uses a discount rate of 12%, what is the net present value of this project? 3. If the company has a rule that no projects will be undertaken that have a payback period of more than five years, would this investment be accepted? If not, what arguments could the energy manager make to try to obtain approval for the solar panel project? 4. What would you do if you were in charge of approving capital investment proposals?
