Q¡GWhat is ?  
     
 

A¡G is a registered trade mark of iWIND ENERGY CO., LTD.

symbolizes that iWIND small vertical Axis wind turbines (VAWT) are of the intelligent type, and have high-efficiency power generation capability. While the world people become aware of loving the earth is everyone¡¦s responsibility, we Cell Power, the mother company of iWIND, also want to do something helpful. Making great efforts for researching and developing the techniques and applications of small VAWT is what Cell Power are doing for the earth now, and wish the global warming can be effectively abated.

  
 
 
 
Q¡GWhat factors should be considered for wind turbines to be chosen?  
     
 

A¡GChoosing wind turbines should consider the following factors: installing sites, wind speeds, required power outputs,
application conditions, etc.

  • Installing site:
    • Urban/metropolitan areas, parks, recreational places, small factories, schools, communities, farms, fish farms, roads, bridges, etc.Vertical Axis Wind Turbines (VAWT)

  • wind speed:

Q¡GWhat features do the Blades have?  
     
 

A¡GThe Blades of iWIND VAWT are super designed with the following features:

  • Lift-type of blade outriggers alter resistance for assistance from winds to raise the rotational efficiency of turbines.
  • Special design of blade outrigger kits raise wind-energy-absorbing capacity.
  • Distorted blades have high wind-absorbing coefficient, and enable start-up in breeze.
  • Wind-collecting design enlarges the swept areas for electricity generation.
  • Magnet-floating design of blades reduce rotational resistance to Enhance electricity generation and extend turbine life.
  • Super light blade materials raise rotational efficiency and their small centrifugal force prolongs turbine life.
  • Safe blade design lowers the possibility of harms from blades to personnel.
  
 
 
 
Q¡GWhat features do the Flux-concentrated Generators have?  
     
 

A¡G The iWIND Generators are 3-phase AC permanent-magnet synchronous ones.They are very flat and slim in shape, look very beautiful and easy to get fixed.Their special flux-concentrating designs greatly promote their efficiency; we call them high-efficiency flux-concentrating generators.The iWIND generators are featured with no cogging torque and high torque, very suitable for the application of start-up in slight winds.They are also applicable to the driving systems of various electric vehicles.

  
 
 
 
Q¡GWhat features do the MPPT Controllers have?  
     
 
A¡GiWIND Controllers are featured with Intelligent Digital Signal Processing (DSP), Neural Fuzzy Control, Maximum Power Point Tracking (MPPT), Remote Control and Communication, Automatic Brake System (ABS) for over speed protection, compact, lightweight, super high efficiency, automatic electricity-balance control to extend battery life, etc.
  
 
 
 
Q¡GWhat features do the Non-destructive Installing Methods have?  
     
 

A¡GIn addition to the traditional wind-turbines-installing methods, such as digging holes, doing leak-prevention, making concrete bases and fixing the wind turbines with bolts, iWIND also innovate some non-destructive installing methods, such as

  • Installing iWIND wind turbines on the roof¡Gno need of digging holes or leak-preventing work, the installation is fast and secure.
  • Installing iWIND wind turbines combining with gardening¡Gno need of digging holes or concrete bases, the installation is fast, secure and surrounding-beautifying.
  • Mobile power source¡Gthe portable type of wind turbines can be installed DIY (do-it-yourself) in about 5 minute
  
 
 
 
Q¡GWhat features do the Wind/PV Hybrid Systems have?  
     
  A¡GiWIND Small VAWT can turn into Wind/PV Hybrid Systems with photovoltaic cell plates and connectors added in the places reserved on the tower top.
