1. The blades are made of FRP and shaped by precision injection moulding. The rotor runs smoothly and quietly. The aerodynamic performance of rotor is excellent with high energy coefficient and low start-up/cut-in wind speed. The rotor is able to protect from over-speed by blade aerodynamic elasticity.
Using high performance NdFeB permanent magnet, the alternator is high efficient and compact. The unique electro-magnet design makes the bonding force and cut-in speed very low. . |

| 2. Relying on the blade aeroelastic and electronic protection and discarding any mechanical protection set, Worldwind wind turbines have only two pairs of parts with relative rotation to make structure compacter and more reliable. |
| 3. The system controller, using PWM and microprocessor technology, makes the wind/solar hybrid system output maximum, and protects the wind turbine and battery from malfunction. |
