If he had some extra $$$ he could have invested in a solar panel system. Mine easily takes care of of my household needs and the electrical needs of my tanks. I won't sugar coat it but its a rather steep investment depending on how large you go. It does nearly take 20 years to pay off but I do get a check from the electrical company every month because I actually sell them energy lol. It isn't much but 30-100 dollars a month does add up lol.
