You don't want a wind turbine. In order for most of them to make their rated power they need a wind of about 28 mph. That's pretty stiff around here anyway. They also need to be mounted at least 30 feet above anything within 500 feet. Even if you're in wide open spaces putting up a 30 foot mast and guying it off would be a lot of work. Then there's the noise and vibration a spinning turbine generates.
Could you put a little one on a tiny mast and have it make a little bit of power in a light breeze? Maybe, but why? Just get another solar panel.
