Basically what happens is the power you use for example 100kw is taken from your meter then the solar is put into the meter say 90kw you are ten charged normal rated for the usage say 30c a kw but the other way around if you make more you get say 16c a kw or whatever your deal is.
And I don't look at how long it will take to pay off I look at that ill never need to find that $700 plus whatever increases the power companies decide to bump it upto again.
