The higher your electric rate from the utility, the faster your solar energy system pays for itself, since each kilowatt-hour of solar is saving you that higher rate. This homeowner enjoys a pretty good rate from her municipal light department, so her system will take a little longer than some to pay for itself. In the meantime, she’s enjoying an 82% reduction in her electric bills, so life is good!
