Item
Horizontal axis (HAWT)
Vertical axis (EML)
Start wind speed
High(3m/s)
Low(1m/s)
Wind conditions required
Require stable wind direction
Any wind direction
Encountered turbulence
Reduce the efficiency
Efficiency is not affected
Power stability
Change by wind direction
Without any wind effect
Noise
Large(45 decibels or more)
Low noisy(because there is no
mechanical friction)
Product shape
Normal
Beautiful
Installation height
High(need to avoid the terrain
turbulence)
Low(not afraid of turbulence)
Installation location
Just in open area like suburb
Any location
Generator material
Plastic or composite
metal
Structure strength
Poor (easy to broken)
High(high strengthen )
Resistance of wind speed
Poor(about 40 m/s)
High(about 65 m/s)
Safety in utilization
poor
high
weight
about 20KG
about 38KG
