To figure out if going solar is a good idea, start by looking at your monthly utility bills. Multiply that amount by 12 and then by 25 to see how much you might spend on electricity over the next 25 years (if rates don’t increase). Think about what you’ll have to show for that money in the end. Are there any benefits to sticking with the utility company? How sure are you that their rates won’t go up a lot, causing money problems? Right now, you’re renting power and the cost can change, but if you own your own solar power, you can save a lot of money in the long run with a fixed rate. And don’t forget about possible extra savings from incentives.
