Understanding Small Wind Turbine Components


Thanks to the rising cost of energy and the availability of information explaining alternative energy sources; many homeowners are considering other options to power their homes.  Wind power is a popular choice. While you have heard about wind power in the news, you may not know how it actually works as an energy source to power your home.  Here are the basics to help you understand the components of a small wind turbine.

  • Most wind turbines have several different parts that you should be aware of. These parts include blades, a rotor, a generator, a tail, a tower, and batteries or an inverter.  The most common type of turbine is a horizontal axis upwind turbine.  These models typically have either two or three blades, and the blades are made of a composite source.  Two blades seem to be the optimum number for a balance of wind speed and power output.
  • When you are choosing a wind turbine, an important factor to consider is the rotor. The diameter of the rotor is largely responsible for determining how much power the wind turbine will create.  The term swept area refers to the amount of wind picked up by the turbine.  The size of the swept area is determined by the diameter of the rotor.
  • The frame is the base that holds the rotor, generator, and tail. The tail is placed there to balance the structure and keep it pointing the right direction, into the wind.
  • The turbine is located on a tower. Wind speed is increased when the turbine is mounted higher, so a taller turbine creates more power and gives maximum efficiency.  A tall tower also brings the turbine up and out of the way of things like houses and trees that can create air turbulence. You can determine the height of the tower that you need by taking the height of the tallest obstruction within 500 feet of your turbine and doubling it.  For example, if a nearby obstruction is 50 feet tall, you should choose a tower that is 100 feet tall.  If you are unsure of what height to choose, it is best to go higher. While the investment to increase the height of the tower is small, the increased output of power is great.
  • You will also have to choose between a free standing tower or anchored tower.  Anchored towers are the less expensive and more popular option.  A tilt down tower is a good choice because you can tilt it down in order to perform maintenance or to protect it in severe weather.
  • You will also need balance of system parts.  The particular components you need will vary depending on the specifications of your turbine, but often include things like batteries, an inverter, and wiring.
