When in operation, not only do the blades need to withstand more force, the bearing between the rotor and the mast also needs to endure higher pressure.
Often placed on ground level and populated environments, vertical axis wind turbines face more turbulence and issues of vibrations.

#Home wind turbine vertical axis generator
The rotor and the mast combined tower our vertical axis wind turbine to 10 meter high, with the generator and power electronics located at the 4-meter height.Ĭompared to horizontal axis wind turbines, vertical axis wind turbines operate with lower wind speed. To address this problem, we have improved the rotor design so that it can be mounted on top of a mast.
#Home wind turbine vertical axis install
A common solution to this is to install the turbine on the rooftop of a building. Consequently, less wind energy is available for ground-level vertical axis wind turbines. Since vertical axis wind turbines are typically installed on ground level, they do not harness higher wind speeds often found at higher levels. This is especially shown on Savonius wind turbines because they have wider blade surfaces. During rotation, vertical axis rotors are also faced with more drag- or aerodynamic resistance- on the blades. In fact, only the wind-facing blades are driven by the wind to turn while the others are simply following along. This is part of the reason why vertical axis wind turbines have lower efficiency.ĭue to the rotor design, not all the blades on the vertical axis rotor receive incoming wind at the same time. Vertical axis wind turbines often have less rotation efficiency. The challenges brought by disadvantages of vertical axis wind turbines Through 5 years of research and development, we have also come across and addressed certain problems and improvements of vertical axis wind turbines. In fact, the design of this type of turbine remains popular as engineers come to tackle the challenges. However, they have a few disadvantages as well. Vertical axis wind turbines have 7 key advantages that make them perfect for small-scale power generation in unstable windy regions and urban areas.
