Advantages of 5-blade wind turbines over 3-blade wind turbines 1) 5-blade wind turbines will greatly improve annual energy production in low wind conditions. For areas with average wind speeds of 11 MPH (5m/s). If you compare annual energy output to conventional 3-blade wind turbine, there is an increase of annual energy output of more than 60%. 2) 5-blade wind turbines will dramatically improve the reliability and safety in high speed wind conditions. The blade rotation speed of a 5-blade turbine is 60% of the rotational speed for a 3-blade wind turbine. 5-blade wind turbines will greatly reduce chance of overspeed control malfunction. This will ensure operational reliability from a long term perspective. 3) The lower blade rotation speed of 5-blade wind turbine will lower wind turbine noise and make 5-blade wind turbines more community friendly than 3-blade wind turbines. Nylon-Fiber Glass High Efficiency blades is aerodynamically designed to regulate themselves, slowing automatically in high winds. 1. Strong Neodymium magnet PMA, the unique winding and multi pole design reduces the start-up torque of the alternator that assures generator to generate electricity at low wind speed. 4.5 mph start up wind speed. 2. Electric over-speed control, no more problematic mechanical furling. 3. Innovative low maintenance two-moving-part system design. 4. Easy to Install, Light Weight and highly reliable. 5. Generator: The generator is built using high-performance rare earth neodymium permanent magnets, so the alternator is compact and light weight with a high power generating efficiency. Generator housing is made using precision cast technology from high strength aluminum to assure a high quality finish. It is designed for various working conditions such as severe climate, sand and salt corrosive environments and marine usage. Number of Blades: 5 Blade Diameter: 4.6 Feet Rated 400W @ 26 mph Max 650W wind/solar hybrid output

This system comes with a set of 3 blades, a 600 watt generator, and a hub. Designed and made to pick up the wind power as much as possible. 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). The exact same blades are widely used in commercial wind generators. The performance of the blades is much better than home brewed ones.
