Horizontal Axis Wind Turbine – HAWT

Horizontal Axis Wind Turbines

Horizontal Axis Wind Turbines (HAWT´s) are the dominant wind turbine on the market and it has been in the running for a long time. They have been pursued in different projects and reached big commercial scales all over the world. HAWT´s have the main rotor shaft and electrical generator at the top of a tower. In simple terms, the wind exerts forces on the blades (lift and drag) and turns the rotor. The rotor of a horizontal-axis wind turbine must always be oriented so that the plane of rotation is perpendicular to the direction of the wind.

The tall tower of the horizontal wind turbines allows access to stronger wind in sites which means more energy production. HAWTs are designed to deliver maximum wind energy yield for all types of wind conditions (IEC class I, II and III) and in any location. One of the main advantages of vertical wind turbines is in fact their ability to produce huge amounts of energy in favourable conditions. This technology has a long-term reliability and availability and has proven records in challenging environments.

When to Choose HAWT

To get maximum yield from your wind turbine then you need to get the conditions right. There are various elements that you have to contend with when installing a wind turbine. By narrowing down and eliminating the good conditions from the bad you can make a judgemental decision on whether or not to go through with the investment.

Before you start the installation it is important to assess the wind speed and conditions before taking on a wind turbine, as this is crucial for the turbine’s efficiency. Wind turbines work best in rural areas as this reduces turbulence which is caused by obstacles, for instance, buildings and trees. For best results, an ideal wind speed would reach 5 metres per second and to measure wind speeds there are a number of different devices which are accessible to you. Inevitably with a stronger wind speed then a higher return is received. Small domestic wind systems are beneficial for those who live in remote areas, where electricity mains are unavailable, thus giving you off-grid possibilities.
