The first thing that people ask when I tell them that we installed a solar array on our house is: “how much did it reduce your electric bills?” Now that I’ve had a full year of utility bills, I’m going to lay out how much we’re paying now versus our historical electric bills.
Keep in mind that there are a lot of different factors at play, but there’s no doubting that the savings are substantial in spite of different weather, usage and billing rates. So let’s get to the numbers!
