HY Energy wind turbine special feature- over-speed Control System:
Abandoned the traditional failure-prone mechanical furling system, the blade itself is designed with over-speed braking system which will generate a reverse reluctant torque to lower the blade rotation speed so that the blades and generator can be well protected in higher wind, it solved safety and reliability problems facing by most small wind turbines.
Combination of Electromagnetic braking and aerodynamic braking maximizes energy capture by extending turbines’ operating speed range into higher and lower wind speed which are missed by the old style wind turbines.

Advantages Compared with Solar Street Lighting:
Wider applicable areas – hybrid system offers a much better reliability and sustainability to areas with less solar radiation level, long rainy season or long winter.
Longer battery life – normally wind turbine generates more power during night, part of power generated will supply the light directly, part of power could charge the battery during night, so less charging and discharging loss from battery and also each battery charging cycle is prolonged.
More cost-effective in windy areas – in the area with annual wind speed of 5-7m/s, wind solar hybrid system could have higher production to power higher capacity LED lights or more lights which could lower the system overall cost.
Easier installation & Maintenance – solar street light system cannot put bigger (max. 360W in two sections) PV panels on light pole considering wind load; wind solar hybrid system allows bigger capacity installed on light pole, which could generate enough electricity to power 2-4 LED lights, which means one power system supply for 2-4 lights, it will be easy for installation and maintenance.
