A company decided to develop low-cost photo-voltaic solar-energy cells. It decided on two development choices: a fully automatic line for $800,000 capable of producing 200,000 cells/year for a profit of $1/cell, or a semi-automatic line for $500,000 capable of producing 120,000 cells/year for a profit $1/cell. It is estimated that both lines will last for five years and will have a book value at the end of the five years of 10 percent. Assume both lines will be working to 100 percent capacity. You are the PM for development. Please make all calculations with or without taxes. Assuming an interest rate of 5% and life of n = 5 years with no tax consequences or book value remaining, show sensitivity analysis for PV for semi-automatic machine @ 120,000 cells sold/year @ $1 profit per cell machine, assuming ± 20% variations in the profit per cell and useful life. Plot the PV results versus the profit and useful life ± 20% variations.
