After eight years improvements, our researchers, with creativity, combine solar energy and wind power hybrid power system according to the principle of maglev wind turbine, beautiful and safe , no pull wires, no transformer power supply. It also keeps working for a few days even without sun and wind .
An hybrid wind-solar electric system demands an higher initial investment than single larger systems: large wind and solar PV systems are proportionally cheaper than smaller systems...But the hybrid solution is the best option whenever there is a significant improvement in terms of output and performance - which happens when the sun and the wind resources have opposite cycles and intensities during the same day or in some seasons.
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,less than 40db,(because there is no mechanical friction) |
