Consider a firm taking up a solar energy project i.e. replacing all its electrical power needs with solar power. The firm needs to make an initial cash outflow or investment of $100,000 for purchasing and installing the solar panels. Assuming that the project generates a cash inflow of $30,000 for the first 5 years in the form of saving electricity bill payments i.e. a total of $150,000 cash inflow. Calculate IRR of the project.
