Polygreensolar Low Cost Red Ball Vertical Axis Wind Turbine
Wind turbine Models
1.. Red Ball is more three dimensional and unique with it's compact shape
2.. The Red Ball has the lowest start up wind speed, a little breeze and it will start to generate power
3.. “Double blade design”, is far better than other companies “single blade design” Our Red Ball windward area is much larger, enabling it to generate power at lower wind speeds.
4.. The use of dual-bearing fixed, fan movement is more stable.
5.. Generator using the Three-Phase permanent magnet AC synchronous generator.
6.. With a special rotor design, reducing the resistance of the generator and revolving speed.
7.. Making a better matching between wind wheel and generator.
8.. This wind turbine using the intelligent microprocessor at the max power to regulate voltage.
9.. Simple installation.
10.. Nylon fibre glass, 20% nylon, 15% glass fibre plastic are used as the material of the blade, which makes this turbine tough and more anti corrosion.
