Advantages and Disadvantages of Vertical Axis Wind Turbine

Advantages and Disadvantages of Vertical Axis Wind Turbine Points : Advantages and Disadvantages of Vertical Axis Wind Turbine Advantages
  1. As present is no require of pointing turbine in wind way chosen efficient so yaw drive and pitch mechanism is not required
  2. They are principally proper for areas by extreme climate conditions, similar to in the mountains where they can provide electricity.
  3. Lower hazard for human being and animals as blades moves at comparatively low speed.
  4. Tough supporting tower not required as generator, gearbox and other components are positioned on land.
  5. Less cost based on the same rated power output but by higher efficiency.
  6. Short construction cost as compare to horizontal axis wind turbine.
  7. Simple installation as match up to to other wind turbine
  8. It can generate electricity in every wind direction.
  9. Simple to move as of one place to other.
  10. It can be fixing in city area.
Disadvantages
  1. As compare to horizontal axis wind turbine they are extremely less competent with respect to them this is as they have an extra drag while their blades rotate.
  2. Though this design is less possible to be damaged by windy wind conditions, they are extra likely to stall out and stop spinning.
  3. These types of turbines are not usually well suitable for use in areas of high wind speeds.
  4. They require a first push to start, this action use only some of its own generate electricity.
  5. They have elevated vibration as the air flow close to the ground creates unstable flow.
  6. While just one blade of wind turbine work at a time so efficiency is extremely low.
  7. Gearboxes and excessive yawing decrease the lifespan of these HAW turbines.
  8. As of vibration bearing wear raise which result in enhance of maintenance cost.
  9. Tend to be visual commotion to the human eye.
  10. It create noise pollution.
