More widespread than the vertical wind turbine, the horizontal wind turbine is also more efficient. If it is commonly used in an industrial setting, there are models for home use.
Characteristics of the horizontal wind turbine
The horizontal wind turbine is composed of a mast, whose height varies between 10 and 35 meters, on which rests an assembly of several propellers, generally two or three in number. Unlike his sister, its axis of rotation is mounted in a horizontal position.
There are several types of horizontal wind turbines. The first ones work parallel to the direction of the wind and are of two kinds. We distinguish the horizontal wind turbine "Upstream", which receives the headwind, and the horizontal wind turbine " downstream ", the most common for home use, for which the wind comes back to the pale. The second as for them, less widespread because more complex, have the propellers in perpendicular position with respect to the wind.
Advantages of the horizontal wind turbine
The horizontal wind turbine is today the kind of device that we find most often in the landscape, in the context of wind farms intended to produce electricity on a large scale or a domestic location for the energy consumption of the home, because it is the most efficient.
Indeed, the electric motor that is equipped with the horizontal wind turbine allows it to adapt to the wind direction and thus better capture the energy that results. In addition, its market being more developed, its cost is lower compared to a vertical wind turbine.
Disadvantages of the horizontal wind turbine
Nevertheless, the horizontal wind turbine has some constraints that should be taken into consideration.
If the horizontal wind turbine indeed offers a higher yield than a vertical wind turbine, however, it turns out more capricious in the face of the winds. On the one hand, she is longer to move, the time to capture the direction of the wind and then move towards it. On the other hand, she is more fragile variations and extreme situations such as storms. It requires a ground anchoring reinforced by a guyed mat, but also more maintenance, which represents an additional cost.
Finally, in the context of domestic use, the horizontal wind turbine being more noisy, it is necessary that have a large lot and to install it at a reasonable distance from any dwelling to minimize noise nuisances, including those that may be felt by the neighborhood.
