API Vertical Axis Wind Turbines (VAWT)


  • No massive tower required so construction costs are lower.
  • No Yaw device required.
  • Less noise than HAWT models.
  • Higher airfoil pitch angle improves aerodynamics.
  • Lower wind startup speeds.
  • Larger swept area than HAWT’s with the same radius.
  • No turning to face the wind so VAWT’s are ideal for turbulent conditions.


All Turbines have 5 Blades with an operating wind speed of 4-25 meters/sec
(9-53mph) and a System Efficiency above 26%.
System Price includes Generator, Blades, Controller.
API-500W, 1KW, 3KW, 10KW VAWTs also available in Grid Tie versions.
