Figuring out what size system you need is easy. All you need is your electric bill. Take a look to find out your monthly kilowatt hour usage. (Better yet, take a year's worth of bills and average it out.)

This Kilowatt hour (KWH) number determines your system size. Once you've got it, look over to the left. Your number should fall in one of the three column headers. That column is your solar solution.
