The annual energy bill for a typical single family American home is $1,255, resulting in $144 billion spent per year for 115 million U.S. households.
The amount of money you save by going solar depends on many different factors: Energy prices fluctuate by state. The national average per kilowatt hour (kWh) is $0.117.
Going solar is even more cost effective if you live in one of the states with really expensive grid power: California, New York, New Jersey, COnnecticut, Massachusetts, Rhode Island, Vermony, New Hampshire, Hawaii, Alaska or Delaware.
The position of your home and the way the sun hits it affects how much solar energy you can generate (and therefore, how much money you’ll save).
