GREEF vertical axis wind turbine (VAWTs) is a type of wind generator where the main rotor shaft is set vertically.VAWTs offer a number of advantages over traditional horizontal-axis wind generator (HAWTs).They can be packed closer together in wind farms, allowing more in a given space.They are smaller, but rather due to the slowing effect on the air that HAWTs have, forcing designers to separate them by ten times their width.
GREEF vertical Axis wind generator are rugged, quiet, light, Omni-directional, and they do not create as much stress on the support structure.They do not require as much wind to generate power, thus allowing them to be installation at urban .They are easily maintained and can be installed on rooftop and similar tall structures.
• Household, Garden, farm,Urban,Rooftop
• Telecom sites.
• Rural electrification programs. Island, sentry, island, sight lighting.
The 2kw vertical axis wind turbine is often used in conjunction with solar panels to provide more reliable year-round energy supply.

Advantages of Axial Flux Coreless Disc Generator
1. Torque Patent Technology: use newest "Precise Coil" technology. No hysteresis and gear notches effect make the start torque very low <0.3N.M ,it can make the wind turbine have low start wind speed.
2. Original Structure: use disc coreless motor to take place traditional motor makes it less drag
3. Higher Reliability: special structure make it bigger ratio of power to volume, power to weight and have long life of 8 times longer than traditional motor.
4. Gearless, direct drive, low RPM generator.

1. Q: Why buy a small wind turbine ?
A: A GREEFwind turbine is a smart investment that will lower your monthly expenses, increase your net worth. At the same time, it will help clean the air, slow climate change, and move us towards the energy independence. You will also enjoy watching your utility meter turn backwards and the lively interaction between the wind and your GREEF turbine. Finally, it will totally change your view of wind - you will start appreciating windy days. For those fortunate enough to have a windy site of at least one acre, a GREEF wind system will be substantially less expensive than a comparable solar system, it will take up less space, and its performance won't degrade over time. It's like buying vs. renting a home. Over the next 10 years a typical homeowner or small bussiness will pay $18000 to over $5000 in electric bills , at rates that often increse faster than inflation. When you choose a GREEF wind system you take the same monthly expense and invest it in a tangible asset. Once your GREEF turbine is paid off, you will enkoy more money in your pocket every month for the next 20years.
2. Q: Does 5kw vertical axis wind turbine installation Easy?
A: Very easy, every customer can install it by themselves, we will supply all the components for installation and very details installation manual.
3. Q: Does our wind is enough for a 5kw vertical axis wind turbine?
A: As our 5kw vertical axis wind turbine can start running at low wind speed 1m/s. so your average annal wind speed is 4- 5m/s then you can use it.
4.Q:Which model is suitable for me?
A: Please contact our sales with following points:
1. How many watts your house consume per day.
2. Your annual wind speed.
3. What kinds of system do you want? On-grid or off-grid?
Any other questions, please feel free to contact us.
GreeF company sales team will give you our best service !
