Look into solar powered appliances. There are a number of products that are available that are powered by solar energy. One of the most popular is the solar powered water heaters. Just having one appliance run by solar energy can save you hundreds of dollars each year in energy costs.
Make sure to allow for adequate spacing around your solar panels. When overheated, these panels do not work effectively, and this can diminish the amount of energy they create for your family. Allowing for space between and around each panel helps to promote air flow and maximize both the functioning and lifespan of your panels.
