Difference Between Horizontal and Vertical Axis Wind …

A significant advantage of vertical axis wind turbine over horizontal axis type is that the former can accept wind from any direction and thus no yaw control is needed. In VAWTs, the wind generator, gearbox and other main turbine components can be set up on the ground, which simplifies the wind tower design and construction and consequently reduces the turbine cost.
