A vertical-axis wind turbine (VAWT) is a type of wind turbine where the main rotor shaft is set transverse to the wind while the main components are located at the base of the turbine. This arrangement allows the generator and gearbox to be located close to the ground, facilitating service and repair.

Savonius wind turbines are a type of vertical-axis wind turbine (VAWT), used for converting the force of the wind into torque on a rotating shaft. The turbine consists of a number of aerofoils, usually—but not always—vertically mounted on a rotating shaft or framework, either ground stationed or tethered in airborne systems.
The three primary types: VAWT Savonius, HAWT towered; VAWT Darrieus as they appear in operation. Wind turbines can rotate about either a horizontal or a vertical axis, the former being both older and more common. [37] They can also include blades or be bladeless. [38] Household-size vertical designs produce less power and are less common. [39]
Hi-VAWT’s services including vertical axis wind turbines (ranges from 300 to 3000 watts system), solar panels and hybrid street lights system. The DS-3000 wind turbine system currently is the only vertical axis wind turbine system that has been certified by Nippon Kaiji Kyokai [16] and qualify for Feed-in tariff application in Japan and Taiwan.

The Darrieus wind turbine is a type of vertical axis wind turbine (VAWT) used to generate electricity from wind energy. The turbine consists of a number of curved aerofoil blades mounted on a rotating shaft or framework. The curvature of the blades allows the blade to be stressed only in tension at high rotating speeds. There are several ...
