Wind turbines that do not spoil the landscape and easily blend into the surrounding scenery.
The "9kW machine" is a multi-lens wind turbine that can achieve approximately 2 to 3 times the power generation of wind turbines with the same rotor diameter. The source of aerodynamic noise, the tip vortex, is suppressed, significantly reducing noise levels. Additionally, it has been confirmed that bird strikes, which are considered one of the major issues in wind power generation, are less likely to occur. 【Features】 ■ High efficiency due to increased inflow wind speed ■ Reduction of noise generated by tip vortices ■ Improved aesthetics due to the round shape of the lenses *For more details, please download the PDF or feel free to contact us.
