Southwest Windpower Skystream 3.7
 |
Introducing Skystream 3.7® – a new generation small wind turbine that hooks up to your home to help you reduce your monthly electricity costs. Designed for homes and small businesses, the Skystream 3.7® converts wind into clean electricity you can use. It’s the first compact, user-friendly, all-inclusive wind generator (with controls and inverter built in) designed to provide quiet, clean electricity in very low winds.
With a rated capacity of 2.4 kW, Skystream can help offset a household or small business’s total energy needs. Its sleek, distinctive swept-wing blades and elegant form make Skystream an attractive addition to any home. With a guyless tower, Skystream blends in like a neighborhood street lamp. And because it operates at a low RPM, Skystream is as quiet as the trees blowing in the wind.
Developed in collaboration with the U.S. Department of Energy’s National Renewable Energy Laboratory, Skystream was designed from the start for homeowners looking for a quiet, convenient, affordable way to protect themselves from ever increasing electricity costs.
How it works is simple. With no batteries*, Skystream connects directly to your home. When the wind is blowing, your home is powered (in part) by Skystream; when it’s not, your home is seamlessly powered by your utility as usual. During periods of strong winds, Skystream can actually produce excess electricity. Depending on your utility, your meter will spin backwards—giving you credit for a later date.
*Battery charging for home energy back-up systems is also available.
