Calculating the right number of solar panels begins with understanding your energy needs. Knowing how much power your home uses helps you design an efficient solar system. I start by reviewing past energy bills, focusing on monthly kilowatt-hour (kWh) usage. Most bills mention the total kWh under electricity usage.
Sun Number looks at four individual scoring categories, including how suitable a building is for solar, the regional climate, local electricity rates, and solar costs in the area. The higher the Sun Number, the better the conditions for installing solar panels. There are four individual scoring categories that make up the total Sun Number score:
You can calculate how many solar panels you need by dividing your yearly electricity usage by your area''s production ratio and then dividing that number by the power output of your solar panels. To put it simply: Number of panels = annual electricity usage / production ratio / panel wattage
Sun Number was developed with the help of the U.S. Department of Energy''s SunShot Grant to make understanding solar a little bit easier.
