Working principle of wind solar street lights
Solar and wind energy is unlimited and clean energy. Wind solar energy street light make the most use of this unlimited 

energy. The power gained and stored from sunlight and wind is best for the Earth. There would not be any pollution.
Wind and sunlight are transformed into electric energy through wind turbines and solar panel. When it becomes dark, 

accumulator supply electric energy to light light automatically. When the light is lit, timer begins to time. The light will 

go out after a specific period of time automatically. 
Wind turbines
High-performance windmill which can adapt to all kinds of environment
(1) Three-blade optimal design, which can generate electricity under weak wind
(2) Noiseless work, which can restrain sound of fans
(3) Strong wind resistance. Horizontal deflection-type protection
