Harnessing The Power Of The Wind, Turning Motion Into Electricity

When we think about renewable energy, we usually talk about solar energy. Nevertheless, apart from solar energy, there are other significant renewable sources of energy too. Amongst them, wind energy might be the most prominent. In fact, generating energy using a wind turbine is a very common practice. Gigantic rotating wind turbines is a common sight in many parts of the world. In addition, unlike solar energy wind energy is available throughout the day. Therefore, it has much better potential to work practically as clean energy. However, wind energy too has its own pros and cons, which become even more evident when we consider two ways of utilizing it i.e. through Vertical Axis Wind Turbines and Horizontal Axis Wind Turbines.
Also, the vertical wind turbine generator is omnidirectional meaning that it does not require orientation of the blades into the oncoming wind, as by its design, it always does.
In our mission for sustainable energy solutions, vertical wind turbines have emerged as a promising alternative to their horizontal counterparts. These innovative turbines operate on a vertical axis, with vertically oriented blades, and offer several distinct advantages that make them an excellent choice for a variety of applications.
Advantages of VAWT:
Nearly Quiet
More Safety
Captures Wind From Any Direction
Birds Friendly
Longer Working Life
Less Maintenance
Less Requirements on Foundation
Lower Supporting Tower

Rooftop Vertical Axis Wind Turbine Space-efficient.

How does it work?

Rooftop installation maximizes land use and avoids the need for additional space.
However, when considering a VAWT installation on a rooftop, it is crucial to ensure careful planning and assessment to make the most of its benefits while considering potential limitations.

Structural considerations:

Rooftop installations require careful assessment of the building’s structural integrity to support the additional weight and vibrations of the turbine.

Local regulations:

Rooftop installations require careful assessment of the building’s structural integrity to support the additional weight and vibrations of the turbine.

Vertical Wind Farm

Research has shown that VAWT could increase the efficiency of the wind farm by almost six to nine times as compared to the HAWT. The use of VAWT also decreases the total demand for land for the wind farm. It is because one can place them close to each other. This is possible as they do not require the erection of huge towers for mounting the turbines.
Since in the vertical axis wind turbine the blades are wrapped around the shaft, they are normally safer for birds. In a horizontal axis wind turbine, the blades spin in the air causing all sorts of problems for birds.
People living in the neighbourhood of a conventional horizontal axis wind turbine often complain of the constant noise and vibration that their spinning blades produce. To the contrary, vertical axis wind turbines operate a lot more silently and do not cause any vibrations to trouble people living in their close proximity. This silent and vibration-free operation makes vertical axis wind turbines a better option for placement in urban areas.
The vertical axis turbine is manufactured exclusively in Italy. Its design is suitable for urban areas and situations where turbulent wind makes traditional horizontal axis wind turbines impractical or where space is limited. The turbine can capture wind from any direction without requiring a tracking system and can be installed without the need for concrete foundations using screw pile foundations.

High Wind Endurance

With the 360° wind pick-up design and robust construction, the vertical turbines function even under air turbulence and frequent changes of wind direction.

Easy Maintenance

With the generator situated at a low height of just a few meters from the ground, the installation and maintenance of the turbines do not require a large workforce.

Flexible Mobility

From coastal regions to faraway islands, from mountainous areas to off-grid communities, the turbines can harvest wind power almost everywhere and anywhere.

Low Environmental Impact

Turbines create no drop shadow, pose a smaller threat to flying animals, and emit lower operation noise.

Easier Installation With Minimum Requirement

With their compact design and user-friendly features, they can be easily installed in various locations without having to make major changes to the infrastructure. Whether for residential, commercial or industrial applications, these turbines are perfect for any scale.

The Design

The Darrieus wind turbine rotor (named after its French inventor) consists of three thin vertical blades mounted onto a vertical shaft.

The Darrieus rotor works on the principal of lift forces (similar to the horizontal aerofoil rotor) with maximum driving torque produced when the shaped blades are moving across the wind faster than the speed of the wind.

Wind Power Requirements

How does it work?

The amount of energy generated by a wind turbine depends on:
wind speed (main factor)
the area swept by the blades
air density
Wind turbines require:
Range wind speed 6 -11 m/s to begin turning and generate electricity
strong wind speed of 20 m/h; beyond that speed, the turbines it will stop to avoid damage

Key Information To Know

How do I verify wind presence?

While national or regional wind maps issued by meteorological authorities may be used as a cautious estimate of the local wind resource, they lack detailed information about the specific characteristics of a particular site. These maps often do not account for factors such as wind speed distribution, direction distribution, turbulence intensity, and the impact of the surrounding landscape and nearby structures. To obtain a more precise assessment of the wind conditions, we recommend our customers to have one of our technicians install a local anemometer at the appropriate height, which will provide a more accurate wind assessment report.

What is necessary to be done to define the installation site for a wind turbine?

Verify that there are no legal restrictions.
Carry out an anemometric analysis lasting at least three months.
Check the accessibility for heavy vehicles to the place of installation and related permit.
Check the space required to mount the wind turbine.
The aforementioned elements affect the cost of the system and consequently the investment payback.
