9.2 ft. Diameter 1 kW High Efficient Wind Generator Rotor w/ HUB and Nose Cone
 | This listing is a set of wind turbine rotor assemblies for a 1 kW wind generator at 22 mph wind speed. they are designed and made to pick up the wind power as much as possible. The exact same blades are used in commercial wind generators. The performance of the blades is much better than home brewed ones.
The efficiency is graded as 0.48 in converting wind power to the mechanical power, which is at the very top end (the highest is 0.5). | |
