Solar power systems that are installed on your home are amazing they take sunlight and convert it into electricity! It's electrifying! If it is a very sunny day then more electricity will be produced than if it is an overcast day. An average home can expect to generate around ten watts of power per square foot of solar panel per day. However this figure can vary depending on the size of the panels that you use.
