| Skystream 3.7 Wind Grid Tie |
| Skystream 3.7 1.8 kW Wind Generator The Skystream 3.7™ is a new generation residential wind generator that hooks up to your home to reduce or eliminate your monthly electrical bill. It’s the first all-inclusive wind generator (with controls and synchronous inverter built in) designed to provide quiet, clean electricity in very low winds. This makes Skystream ideal for residential homes and small businesses. 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. Depending on the wind speed average and the amount of energy consumed every month, Skystream typically lowers a household electricity bill by 30% to 80%. It is not uncommon for Skystream owners with total-electric homes to have monthly utility bills of only $8 to $15 for nine months of the year (2005 data). The amount of money a Skystream saves you in the long run will depend upon its installed cost, the amount of electricity you use, the average wind speed at your site, and other factors. Skystream is extremely quiet and makes a small amount of operating sound similar to the level of a small office. It generally cannot be heard over typical background noise such as the sound of the wind. Skystream does not interfere with TV reception. Monopole tapered "towers" as short as 35 feet are available with the Skystream. The monopoles are very aesthetic and look very hi tech but they have to be delivered with a tractor trailer because of their length. In some circumstances, a taller tower may be necessary to raise the generator above turbulence created by obstacles on the ground and/or trees. Wind speed increases with height above ground, and increasing speed increases the amount of energy your generator will produce. Relatively small investments in increased tower height can yield high rates of return in energy production. A rule of thumb for proper and efficient operation of a Skystream suggests that the generator should be 20 feet (6 meters) above the top of anything within 300 feet (about 100 meters). In accordance to IEEE and UL, Skystream will automatically shut down in the event of a power outage, and will not energize a dead power line. This is necessary to protect the utility line repair people.
