Energy per square foot of solar panel.

Sunpower solar panels are the most efficient you can buy. But every home is unique and could use more or less power than the average home. For those wondering how we estimated those numbers for energy consumption and required number of solar panels here s the breakdown. How many solar panels are needed to power an average house.
