First thing you do is call your local power company and make sure their lines a good enough to carry your excess electricity. I know people who bought a system to use and sell solar electricity, the solar company told them they would make lots of money from it so they bought it
when they tried to get the final hook up inspection hydro told them that until the lines are upgraded in about 10 years or more it can not be used for transporting your excess power.
so the more remote your location the less likely you can do it
