You are considering the installation of a 2 kW solar photovoltaic system on the rooftop of your residence. The initial costs are $19,750. The federal government offers a tax credit of 30%, and the state adds an additional credit of 10%, both of which are applied at the end of the first year. Your current electric bill averages $2000 annually. The solar PV system will generate more power in a year than you will use. You will be able to take advantage of the state's net metering policy and sell your surplus power to the utility for an estimated $600 each year. Based on present worth at a MARR of 3% and a planning horizon of 8 years, is this a good investment for you to make?]
