Designed Specifically for Grid-ConnectivitySkystream 3.7™ is specifically-designed for grid-connected home and business use. In certain states consumers can take advantage of ‘net-metering,’ or the sale of unused energy back to the power grid.Low CostA wind power engineering breakthrough, Skystream 3.7™ is the first residential wind appliance to produce energy at a cost ($.09/kWh) that is lower than the retail rate of many electric utilities. Depending on the tower and installation costs, wind speed average, rebates and local electricity costs, Skystream 3.7 can pays for itself in as quickly as4 years. All-in-One SolutionSkystream 3.7™ offers a simple, all-in-one solution to harnessing wind energy on a residential scale. Different from all other technologies, Skystream 3.7™ is the first all-inclusive wind generator with the controls and inverter built in. Rather than converting an inverter designed for grid-connected solar, the inverter was designed specifically for this application.
Exceptionally Quiet OperationSkystream 3.7™ operates exceptionally quietly. In fact, Skystream 3.7™ is unrecognizable over trees blowing in the wind. Designed for very low winds, Skystream 3.7™ begins producing power in an 8 mph breeze with full output achieved at 20 mph. Low ProfileSkystream 3.7™ can be mounted on a 35 ft. tower. This means a vast number of households on one acre or larger lots will now have access to residential, grid-connected wind energy. Towers up to 110 ft. are available. A site assessment is important to determine the best tower height for your site.
