Description
400w vertical wind turbine features
1,VAWTs are better able to harvest turbulent air flow found around buildings and other structures
2,VAWTs are ideal for both rural and urban applications, including roof top installations. Depending on the shape of the roof, the wind flow over the roof can be concentrated, leading to an increased energy output
3,Simple to install and maintain

FAQ:
1.Why are your prices so low, are these quality items and brand new?
We sell brand new items directly from factory in Asia. That is why our prices are so competitive.
To maintain quality control ,we do personally inspect for each item prior to shipment. All items are 100% new and inspected.
2. What kind of region can be installed wind turbine?
Small wind turbines should be applied in the regions which wind reso urces is sufficient. The annual average wind speed should be more than 3m/s, the effective wind speed 3-20m/s should be more than 3000h in accumulation per year. The density of 3-20m/s effectively average wind power should be more than 100W/m^2
It should be noted that choosing the rated design speed wind turbine is in conformity with local design speed. It is significantly in making use of wind resources and in economic aspect. Wind tunnel test proves that the fan power transformation of the impeller in the direct ratio with wind speed, that is to say, the wind speed decide the output electrical power.
