There are small rooftop models available, although their efficiency may suffer – usually you want the turbine elevated about 30 ft (9 m) above the tops of any buildings in a 500 ft (150 m ) radius to avoid low wind speeds and turbulence. If you have sufficient space next to the house to place a tower like that, you’ll have much better energy production. In any case, you may consider placing rooftop solar panels, especially if your geographical position has a lot of insolation but little wind.
