Small Wind Turbines for Farms, Homes and Small Businesses
Wind power is the conversion of wind energy into a useful form. Windmills use wind energy directly as mechanical energy for pumping water or grinding grain. Wind turbines, however, use wind energy to turn a generator that produces electricity.
Small wind turbines are electric generators with rated capacities of 100 kilowatts and less. Small wind turbines utilize wind energy to produce clean, emissions-free power for individual farms, homes and small businesses. With this simple technology, individuals can generate their own power and cut their energy bills while helping to protect the environment.
Soenso Solar is a dealer and professional installer of the “small wind” Skystream 3.7 Wind Turbine, manufactured by Southwest Windpower in Flagstaff, Arizona, USA. With a rated capacity of 2.4 kilowatts, it is a fully-integrated, utility-connected, clean, quiet wind generator designed specifically for farms, homes and small businesses.
Skystream 3.7 requires less than one acre of land for operation. It is installed on a self-supporting monopole tower (no guy wires necessary) with a substantial concrete and rebar foundation. The Skystream 3.7 is the first “plug and play” backyard wind generator. Its inverter is built-in, requiring no external box or wiring. The Skystream 3.7 is UL certified and has a five year manufacturer’s warranty.
The average annual wind speed in Georgia is 9.1 mph (Source: National Climatic Data Center). Some sites in higher elevations of the north Georgia mountains have average annual wind speeds of 12 mph (Source: 3TIER FirstLook). The Skystream 3.7 may generate approximately 200 kWh/month with 9 mph average wind speeds and may generate approximately 400 kWh/month with 12 mph average wind speeds. A typical home in Georgia uses about 1,000 kWh/month of electricity. Therefore one Skystream 3.7 usually powers only a portion of a home’s total energy requirements.
Soenso Solar works with agricultural producers, architects, engineers, contractors, developers, electrical contractors, general contractors, homeowners, LEED APs, property managers, school administrators and other professionals to assist them with incorporating sustainable building practices such as wind energy. Under LEED 2009, points can be earned by providing wind energy that meets LEED-established percentages of a building’s energy requirements.
Rough estimates of pricing for the Skystream 3.7 vary according to tower height. A Skystream 3.7 with a 45’ tower is approximately $14,000. With a 55’ tower it is approximately $16,000. And with a 70’ tower it is approximately $20,000. Generally, the taller the tower the more efficient the wind turbine operates. These prices do not include installation, which vary from about $8,000-$12,000 depending on ease or difficulty of installation. These estimates are not price quotes and are subject to change.
Soenso Solar is also a dealer of the Air Breeze Wind Turbine from Southwest Windpower. The Air Breeze is a small, recreational-size wind turbine that has an energy production rating of 38 kWh/month at 12 mph average wind speeds. It can be mounted on sailboats, lakeside cottages, recreational vehicles and even mobile sound stages. The Air Breeze is priced at $900.00. This price does not include tower, installation and sales tax.
