The Darrieus wind turbines are speciffically well fitted to energy production for small systems.
The behaviour and the characteristics of the Darrieus wind turbine made them the best solution to harvest energy from variable winds ( gusts, acceleration, direction changes) such as winds close to ground. At the contrary to the conventionnal "horizontal axis wind turbine", the "vertical axis wind turbines" (VAWT) do not require to orientate depending to the wind. The rotor is able to harvest energy whaterver the direction of the wind, even gusts.
During wind orientation shift, which is very frequent at low height, the vertical axis wind turbine -VAWT- keep on producing energy since the rotor maintain its efficiency. For this reason, they produce more energy than conventional wind turbine for small systems. It is well known that VAWT are the key technoloy for small application, and more especially the Darrieus ones, faster and more efficient than Savonius ones. ÉOLIE has developped the Know-How of the very particular aerodynamic and mechanical behaviour of these machines, and use it to produce VAWT for its customers.
