Guest Houses Corporation is considering buying a solar panel(s) for electricity saving in two of their house's blocks, one based in Johannesburg and the other in Cape Town. They contracted you to advise them whether to buy it or not. With fluctuating weather pattens, it is estimated that the power output can range from 25 kWh to 46 kWh per day. They estimated that they can save up to 9 600 kWh per year using solar system per house blocks. The solar panel company have assured them a guarantee of 10 years in continuous running. They also claim that their footprint is nationally, and they sell their products at similar prices. You collected the following data for your assessment: • Project life = 10 years • Cost of capital = 10% • Estimated electricity output = 38 kWh per day • Electricity output efficiency = 56 % • Electricity costs in Cape Town at year 0 is R2.84 per kWh and expected to grow at 10 % for the project life. • • • Routine maintenance expenses = R7 400 per year. Assume constant amount for the first 5 years and then 3 % for the remainder of the remaining year. • Ignore taxes and depreciations. Electricity costs in Johannesburg at year 0 is R2.76 per kWh and expected to grow at 10% for the project life. Number of days per year = 365 days Cost of solar system = R245 000 Guest Houses Corporation is considering buying a solar panel(s) for electricity saving in two of their house's blocks, one based in Johannesburg and the other in Cape Town.
