Facing escalating electricity bills, they chose to go solar which saves them on average $90.00 a month, or a total of $1,080 in the first year. Now they are saving money, especially in the summer when their electricity bill would have gone up to accomedate their air conditioning unit, but now stays at $8.00 a month!
