Regardless of how many solar panels you install, your solar energy system will pay for itself in roughly the same amount of time. Why? Because the more panels and the higher the purchase (or loan) price, the more electricity and green income you make. So don’t worry about how many panels you need. Talk to us about your energy goals — how much of your electric bill do you want to offset? From there, we’ll help you size the system appropriately.
