Off Grid Solar System Sizing Calculator

Use our Off-Grid Solar System Sizing Calculator to estimate how many solar panels you'll need, based on how much power you'll be using each day. All you need to do is enter your appliances along with how many, how long they're running, and how many watts. If you have appliances with an Energy Star sticker like fridges, you can put that number into the kWh/year column instead. Need a quick run through on using this calculator?
