Skystream is a wind generator designed to be installed on top of a tower to convert the kinetic energy in the wind into electricity to be used in a home's existing electrical system. Cut-in wind speed is about 8MPH and an average wind speed of 10MPH or greater is required for effective power production.
In a typical residential application, a home is served simultaneously by the Skystream and a local utility. If the wind speeds are below "cut-in speed" (8 mph) there will be no output from the generator and all of the needed power is purchased from the utility. As wind speeds increase, the Skystream's output increases and the amount of power purchased from the utility is proportionately decreased. When the Skystream produces more power than the house needs, the meter spins backwards creating a "credit" that can be used later. All of this is done automatically without any interaction by the homeowner. Batteries are not required with Skystream. This wind generator model is not for 'off-grid' systems but is designed to produce power that is combined with your utility power only.
In some areas a premium is paid for excess power produced and not used in the building. In the seven States served by TVA (Tennessee Valley Authority) 100% of power produced from this wind generator will be purchased thru your local utility distributor at $0.15/KWH rate in the Green Power Generation Partner program.
