V126-3.45 MW®
The V126-3.45 MW® is designed for medium wind sites with high turbulence, providing good profitability also in low wind.
V126-3.45 MW® at a glance
Built on the same proven technology as the V112-3.0 MW®, the V126-3.45 MW® IEC IIA/IEC IIB operates on medium-wind sites. Equipped with the industry known structural shell blades, the blades of the V126-3.45 MW® turbine do not weigh more than those of the V112-3.0 MW®.
The 126 m rotor enables greater wind capture, which in turn produces more energy at a reduced cost. The result is exceptional profitability in areas with low wind, and new frontiers for wind energy investment.
