This set of wind generator blades is made of fiber glass and applicable for up to 10KW wind turbines.

Note: Keep away from those fraudulent copies from our competitor, which have the thicker poorly made seam lines, that severely change the aerodynamic characteristics and make lots of noise.

Power: Applicable for 10KW Generators
Diameter: 20.4 feet = 245 inches = 6.2 meters
Weight:: 50lb/blade
Coating: UV coated to prevent ultraviolet damage
HUB Included: No
Balanced: Yes
TSR: 6:1 at heavy load, 8:1 at light load, and 10:1 without load
Efficiency: 0.49
Longevity: 20 years

Designed and made to pick up the wind power as much as possible. The efficiency is graded as 0.49 in converting wind power to the mechanical power, which is at the very top end ( the highest is 0.5). The exact same blades are used in commercial wind generators. The performance of the blades is much better than home brewed ones.
