The Product Difference

Hummer Wind Turbines' unique attributes lead to unique customer benefits

Conservatively Rated
Efficiently Designed
Easier to Install and Maintain
Quiet
Robust

Conservatively Rated

• Power Ratings are Conservative versus our competitor's Optimistic Power Ratings
• At wind speeds below the standard power rating speed of 24.6mph (11m/s), Hummer wind turbines output more power than the competition's respective Rated Power.
  • 1 kW Hummer wind turbine can output >1 kW of power at 18 mph
  • 10 kW Hummer wind turbine can output >10 kW of power at 22mph
• Many competitive small wind turbine models boast Power Ratings that can only be observed at 30+ mph

Efficiently Designed

• Low start up wind speed, low rotating wind speed, 4.5 mph wind speed for full start up
• Blades are made of glass reinforced plastic
• Yaw shaft is made of reinforced aluminum alloy (4.4lbs), 10% the weight of other models
• Tale pole weighs only 1.1lbs, 20% the weight of competitor's models
• The 500W generator weighs only 14.3lbs, 18% the weight of competitor's models
• The 1,000W generator weighs 20% the weight of competitor's models
• Patented inner stator, outer rotor structure, with permanent magnet material and circuit
• The generator is located within the nose cone, which is favorable for heat dispersion

Easier to Install and Maintain

• Simple, three moving parts design minimizes maintenance requirements
• Smaller, lighter turbines are easier to install

Quiet

• Rotor speed (and Tip Speed Ratio) is managed to reduce noise levels, typically <50db
• Efficient design and construction minimizes weight and size, reducing noise levels

Robust

• Stable in strong wind conditions.  Hummer wind turbines incorporate dynamic electromagnetic speed limitation protection and side furling to ensure self-protection.
• The rotor blades are designed according to airfoil standards. The flexible end joint design and balance testing ensure long life.
