Vertical axis wind turbine,
Vertical axis wind turbine (VAWT) is a type of wind turbine whose main rotor shaft is set vertically and the main components are located at the base of the turbine. This arrangement allows the generator and gearbox to be located close to the ground, facilitating service and repair. VAWTs do not need to be pointed into the wind, which removes the need for wind-sensing and orientation mechanisms.
VAWTs offer a number of advantages over traditional horizontal-axis wind turbines (HAWTs),
1: They are omni-directional and do not need to track the wind. This makes them much more reliable due to their not requiring a complex mechanism and motors to yaw the rotor and pitch the blades.
2: The gearbox of a VAWT takes much less fatigue than that of a HAWT. Should it be required, replacement is less costly and simpler, as the gearbox is easily accessible at ground level. This means that a crane or other large equipment is not needed at the site, reducing cost and impact on the environment. Motor and gearbox failures generally increase the operational and maintenance costs of HAWT wind farms both on and offshore.
3: VAWTs do not need to track the windto produce energy as they are omnidirectional; any claimed inefficiencies are in fact cancelled out by the VAWT\'s ability to take advantage of turbulent and gusty winds. Such winds are not harvested by HAWTs, and in fact cause accelerated fatigue for HAWTs.
4: VAWTs (4Navitas) can use a screw pile foundation, allowing a huge reduction in the carbon cost of an installation as well as a reduction in road transport of concrete during installation. They can be fully recycled at the end of the their life.
5: VAWT wings of the Darrieus type have a constant chord and so are easier to manufacture than the blades of a HAWT, which have a much more complex shape and structure.
6: VAWTs can be grouped more closely in wind farms, increasing the generated power per unit of land area.
7: VAWTs can be installed on a wind farm below the existing HAWTs; this will improve the efficiency (power output) of the existing farm.
Research at Caltech has also shown that a carefully designed wind farm using VAWTs can have an output power ten times that of a HAWT wind farm of the same size.
Vertical wind turbine street light system features
1. Safe Design
Vertical blade design,Integrated molding, so there is no risk of a blade flying off, highly increasing the security.coefficient
2. 360 Degree Wind Available
Vertical wind turbine need not to track the wind. So it can adapt to all wind directions and wind speed. The efficiency of wind using is higher.
3. Super Quiet
Vertical wind turbine is much quiet than horizontal wind turbine. Spinning quietly, vertical is suitable for home use.
4. Beautiful Design
Vertical wind turbine is designed with beautiful curve. It is suitable to decorate the road or your roof.
5. Wide Application
Much less limitation to vertical wind turbine installing. Without the long blades, the vertical wind turbine can easily adapt to all kinds of environment. Especially suitable for street lights.

1, When you place order, please tell us the voltage of wind turbine you need, 12V or 24V? It will help us to prepare the product to you sooner.
2, Kindly note that if you expect more efficiency conversion on your wind turbine, please turn to our Horizontal Axis Wind turbines. because the Horizontal Axis efficiency will be higher than Vertical Axis;
But our Vertical Axis Wind Turbine Generators are more safe and quite because of lower rated rotate,
moreover it also has the l ower start-up wind speed andswept area.
Please kindly consider.
3, If you still prefer the Vertical Axis, we suggest that you can connect it with solar panel to together use, Vertical Axis is very suitable for hybrid wind solar system.
