5. Tom Sewel has gathered data on the costs of a solar water heater system. During cloudy days an electric heating element in the solar heating system will provide the necessary heat. The installed cost of two solar panels, a small back-up electric pump, and a storage tank with auxiliary electric heating element is $1200. Due to local subsidies, the net savings in electricity cost will be $60 a year, decreasing at 2.5% each year as the subsidies drop. The solar water heater will not have any salvage value at the end of its useful life, assumed to be 10 years. Can the initial cost be recovered during the life of the solar heater assuming a 1%/yr rate for discounted payback period analysis
