Residential home wind turbine4/15/2023 ![]() There are two basic types of towers: self-supporting (free-standing) and guyed. Most turbine manufacturers provide wind energy system packages that include towers. For example, raising a 10-kilowatt generator from a 60-foot tower to a 100-foot tower increases the overall system cost by 10%, but can produce 25% more electricity. Relatively small investments in a higher tower height can lead to very high returns on electricity generation. The higher the tower, the more electricity the wind system can generally generate. Since the wind speeds increase with altitude, a small wind turbine is mounted on a tower. ![]() The stern keeps the turbine facing into the wind. The diameter of the rotor defines its “swept area,” or the quantity of wind intercepted by the turbine. The amount of energy a turbine will produce is determined primarily by the diameter of its rotor. The turbine’s frame is the structure onto which the rotor, generator, and stern are attached. These blades are usually made of composite material, such as fiberglass. Most small wind turbines manufactured today are horizontal-axis, updraft machines that have two or three blades. In addition to the turbine and tower, small wind turbines also require system balance components. Small Wind Electric System ComponentsĪ wind-electric system consists of a wind turbine mounted on a tower for better access to stronger winds. Home wind turbines are a smaller version of the large turbines you see on the side of the highway generating clean electrical energy from the wind’s kinetic energy. This makes small wind electric systems a good choice for rural areas that are not already connected to the electric grid. Our wind power animation has more information about how wind systems work and the benefits they provide.Ī small wind system can be connected to the power grid via your electricity supplier or it can stand alone (off-grid). Most turbines have automatic Overspeed control systems to keep the rotor from spinning out of control in very strong winds. When the wind turns the wind turbine’s blades, a rotor captures the kinetic energy of the wind and converts it into rotary motion to drive the generator. Wind turbines convert the kinetic energy in wind into clean electricity. The wind is created by the unequal heating of the Earth’s surface by the sun. In this article, we will discuss how to plan, install and maintain a small wind turbine and the total cost. Small electric wind systems can also be used for a variety of other applications, including water pumping on farms and ranches. Help uninterruptible power supplies ride through extended utility outages.Help you avoid the high costs of having utility power lines extended to a remote location.Lower your electricity bills by 50%–90%.If you have enough wind resources in your area and the situation is right, home wind turbines are one of the most cost-effective renewable energy systems at home with zero emissions and pollution.
