Why do vergnet wind turbines have only two blades ?

A 2-blade rotor is lighter, easier to install and easier to tilt down for maintenance or for hurricane protection. The fact that you can tilt them down allows them to be serviced easily and quickly on the ground, without needing hoisting equipment, for the 20-year lifetime of the turbine. In fact, the amount of power produced does not depend on the number of blades but on the rotor swept area, and therefore on the diameter of the rotor. Consequently, a 2-blade rotor harnesses as much wind energy as a 3-blade rotor of the same diameter.

Rotating-hub technology, improved over 20 years by Vergnet and incorporating the latest technological advances in the aeronautics industry (such as helicopter rotors), allows the forces exerted on the structure to be considerably reduced. Drive train and structural elements are consequently much lighter and more durable over time.

Do your 2-blade turbines produce as much power as 3-blade turbines ?

Wind turbine performance does not depend on the number of blades. The power generated depends on the area swept by the rotor, regardless of whether it has two or three blades, while the noise emitted depends on the speed of the blade tip through the air.

Why are vergnet turbine masts secured with guy wires ?

Vergnet uses this design to reconcile performance with ease of installation and transport.

• Guyed masts provide many advantages :
• - Height-for-height, the structure is lighter while offering the same strength. The cost of transporting and installing it are considerable lower.
• - The lightness of the entire structure including its guy wires allows the machine to be lowered for safety or servicing.
• - The installation work that is required, in particular for foundations, is drastically less than for conventional wind turbines.

How can you help me develop my project ?

True to the spirit of partnership that has been driving us since inception, Vergnet supports its customers throughout their entire wind project. Discover the services offered by our experts for developing your project.

Is wind power the right solution for my project ?

Whether a project will be successful depends on various economic and technical factors. Vergnet helps you carry out an initial estimate of the profitability of your project using an online simulator. To evaluate the technical constraints on the installation and operation of your project, see our products and services. Documentation is available for project developers.

Which model of wind turbine is right for my project ?

Each machine has its own advantages. A model will be selected based on the size of your project, as well as any logistical and space constraints and the locally available materials. To evaluate the technical constraints on the installation and operation of your project, see our products and services. Documentation is available for project developers.

Does vergnet still produce low-power wind turbines ?

Vergnet no longer produces low-power wind turbines and now focuses on developing medium-power units with the GEV MP 275 kW and GEV HP 1MW. Vergnet's range of low-power wind turbines has proven to be extremely reliable. Vergnet continues to support its clients and ensures spare parts and servicing for all these machines.

Can you guarantee the operation and maintenance of installed machines ?

The quality of operation and maintenance is of primary importance to ensure the longevity of your installations. We have created subsidiaries in strategic regions to support you in these activities.
Our maintenance offer is adapted to multiple situations.

What wind speed can a hurricane-proof turbine withstand ?

Vergnet is the sole manufacturer of medium-power hurricane-proof turbines. Many hurricane-prone regions have large and ongoing wind farms that provide them with a significant energy source. But wind turbines in those regions can face winds up to 250 km/hr. GEV MP 275 kW and GEV HP 1MW turbines can harness the wind potential in hurricane-prone areas while guaranteeing the safety of people and equipment, thanks to a unique tilting system which allows them to be secured to the ground very quickly in the event of a hurricane warning. Once secured, they can withstand winds up to 300 km/hr.

What is Farwind ?

Farwind refers to remote regions of the world where geographical constraints, lack of infrastructure and lack of logistics make access difficult, although they have massive wind potential that is often left unexploited because most wind turbines are unsuitable for difficult conditions. Farwind covers 134 countries, 1.5 billion people and a potential demand of 2,000 megawatts. These are often developing countries or islands, but not always. In such regions, electricity is usually produced by oil generators at very high cost, whereas wind-generated power is much cheaper to produce.

What is Proxwind ?

Proxwindrefers to the "proximate" or local market in any situation and consists of supplying decentralised power, as in for example erecting a wind turbine in a farmer's field giving the farmer a new long-term resource to support and stabilise his business. The birth of this new medium-power market is clearly evident in Europe and the United States. Specially developed for the Proxwind® market, our GEV MP R wind turbine takes the best of industrial wind power technology and applies it to medium-scale power generation. Our partner network guarantees local services, including advice on development, operation and maintenance.
