V90-1.8/2.0 MW

The V90-1.8 MW and V90-2.0 MW turbines have been designed to make the most of medium and low wind sites. The only difference between the turbines is the software configuration, meaning it’s the same turbine configured differently depending on the wind site. Specifically, the V90-1.8 MW is ideal for IEC II sites whereas the V90-2.0 MW is better suited for IEC III sites. Highly tested and verified, these turbines have proven availability and reliability.
