Project

HAWT VS VAWT
Item	Horizontal axis (HAWT)	Vertical axis
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 appearance	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(double strengthen arm)
Resistance of wind speed	Poor(about 40 m/s)	High
