Horizontal Wind Turbine for Individuals

Most often, the horizontal axis wind turbine for individuals captures the wind (from the front or back depending on the model) with blades assembled in a helix. These rotate around a mast placed horizontally relative to the ground. The generator, driven by the rotation of the helix, is located at the top of the wind turbine.

The horizontal wind turbine is the most widespread type.

There are 2 types of wind turbines: vertical wind turbine and horizontal wind turbine.

Principle of the horizontal wind turbine:

The horizontal wind turbine, also known as HAWT (Horizontal Axis Wind Turbine), operates generally on the same principle as large-capacity wind turbines seen in wind farms:

The propeller consists of two or three blades or more on new models. The second solution is the most favored, as it offers better performance.

Advantages of the horizontal axis wind turbine for individuals:

The horizontal wind turbine is the solution generally chosen for large-scale wind energy. For individuals, the horizontal axis wind turbine has two main advantages:

  • The first advantage of the horizontal wind turbine for individuals is its efficiency. Indeed, it captures its energy to the maximum, as it orients itself to adapt to the wind direction.
  • Furthermore, since this type of wind turbine for individuals is more widespread, finding a seller or installer is easier.

Disadvantages of the horizontal wind turbine:

The horizontal axis wind turbine has some significant disadvantages:

  • Less resistant to strong winds than the vertical wind turbine, the horizontal wind turbine must be reinforced. Thus, in regions where the risk of strong winds exists, guyed masts are used (the anchoring is reinforced), and a brake is installed at the rotor level.
  • Moreover, the horizontal wind turbine for individuals takes longer to start than a vertical wind turbine. Indeed, it must orient itself according to the wind direction, which delays its start-up.
  • Finally, the installation is noisier than a vertical wind turbine.

Note: in some cases, beyond a certain speed, the blades will stop turning as a safety measure.

Frequently Asked Questions

What does a horizontal wind turbine for individuals consist of?
The horizontal wind turbine (HAWT), the most common in large-scale wind energy, captures the wind through blades arranged around a horizontal axis. The generator is located at the top of the mast, and the rotation of the blades (2, 3, or more) around this axis produces electricity. It orients itself to face the wind to maximize its production.
What are the advantages of a horizontal wind turbine for individuals?
• **Better efficiency**: A horizontal wind turbine orients itself to adapt to the wind direction and capture maximum energy. • **Ease of access**: This type of wind turbine is very widespread. It is therefore easier to find available models, as well as specialized installers.
What are the limitations of a horizontal wind turbine?
• **Sensitivity to strong winds**: It must be reinforced (guyed mast, rotor brake) in regions exposed to gusts. • **Sometimes slower start-up**: The wind turbine must orient itself to face the wind, which can delay its start-up. • **Higher noise**: Compared to a vertical wind turbine, the horizontal wind turbine can generate more noise disturbances.
How many blades are recommended for a horizontal wind turbine?
The majority of horizontal wind turbines for individuals have 2 to 3 blades. Models with 3 blades are particularly appreciated for their balance between efficiency, starting torque, and noise level. Some prototypes have more, but they are less common.
Is a brake device necessary on a horizontal wind turbine?
Yes, in areas prone to strong winds, a brake or protection system (such as an electromagnetic brake) is essential to prevent the wind turbine from spinning too fast, which could damage the mast or blades.
Is a horizontal wind turbine always more efficient than a vertical wind turbine?
In an open and windy environment, a horizontal wind turbine is often more efficient due to its automatic orientation and generally superior performance. However, in a very turbulent urban area, a vertical wind turbine may be more suitable, despite lower efficiency.
