Solar hot water and solar electric power
Hot water heating can account for as much as 25% of home energy use, especially if you take long showers and have less efficient appliances. A solar hot water heater costs less than solar electric panels and can reduce 50-80% of your water heating bill. The system usually consists of a collector plate installed on the roof, and a series of pipes connecting the plate to a solar storage tank. For grey days or winter months, there is also a backup water heater.
According to the U.S. Department of Energy (
eere.energy.gov), the price of a solar hot water system included in a 30-year mortgage equates to about $15 per month, which compared to water heating costs may make a system immediately profitable.
