Horizontal Axes Type
(Propeller)
|
|
- High tower can secure high wind
- Stand-alone type requires relatively small installation areas
- Long research period
|
|
- Complex shape of the wings is difficult to produce and process.
- Difficult maintenance
- Hard to control wings to secure wind direction
- Vulnerable to lighting because of using FRP and different heights based on the rotating
- Strong noise
- Does damage to the natural landscape
- Requires 2~3 times faster wind speed comparing with the vertical axes type |

Vertical Axes Type
(CYGNUS) |
|
- Generation regardless of wind direction
- Easy maintenance
- Cheap installation cost
- Easy to produce and process
- Low noise
- Small installation area, environmentally-friendly
- Excellent working at a low wind speed
- Constant height of rotating wings and use Aluminum alloy to make it strong against lighting
|
|
- Low tower secures relatively less wind power against the horizontal axes type
- Korea has a short period of development time but, US is operating 3.50 million units
- Requires 2 times longer length for the wings against that of the horizontal axes type.

Wind Power Generation
|
|
- Available for 24hr generation
- Easy maintenance
- Long annual generation period
- Can generate anywhere
- High energy efficiency(30~40%)
- Cheap installation cost
|
|
- Affected by wind speed
- Affected by seasonal wind speed
- Due to the low energy density, difficult to establish large-scale, high-output equipment
- Horizontal axes type requires measures to solve the noise issue

|
|
|
|
| Photovoltaic Power Generation |
|
- Easy installation
- On sunny day, it can secure the constant amount of electricity
|
|
- Short generating time(3~4hr/d)
- Can not generate on cloudy day or at night
- Low energy efficiency (10~15%)
- Largely affected by seasonal change(Reduced efficiency by lower temp. in the Winter and higher temps. In the
Summer)
- Large installation area(6~10§³/kW)
- Relatively higher installation cost
- Periodic maintenance
- Damage to the natural landscape

Features of CYGNUS Wind Power Generator-Vertival Axes Type |
| |
|
| |
 |
1. Wing(Windmill)
Use new wings developed based on aeronautical engineering. Except for strong wind, the number of rotations is less than 300rpm, making almost no noise.
Also, since it has no driving units, no mechanical noise
2. Generator
In case of less than 3kW, the windmill and the generator rotate all together, and in case of 5kW, only windmill rotates but the generator is fixed.
3. Charge ? Discharge Controller
Charge?Discharge controller is designed to produce maximum performance out of generators and batteries. After converting AC generated from the generator into DC, effectively store the DC in the battery. This controller can be applied up to 7 batteries.
4. Battery
Along with the charge?discharge controller, effectively accumulate the electricity without loss and offering it in a stable way.
5. Dump Resistor
While the windmill is rotating, CYGNUS¡¯s products accumulate the electricity into the battery continuously. When the battery is fully charged, the sensor is activated to turn the dump resistor on automatically in order to protect the battery.
6. Installation Poles
We do not use same poles because installation locations and methods are different depending on the customers¡¯ requirements. CYGNUS provides various types of installation solutions for flatlands, rooftop of buildings, coastal areas, mountainous areas and others. CYGNUS products are designed to perfectly work no matter what the weather conditions are in the installation locations based on the wind state, wind pressure load calculations.

7. Brake
No need to stop the product in the strong wind but in case of emergency or maintenance, use the brake to stop the machine.
8. Change over switch of commercial electricity
In general, the electricity accumulated in DC 12V battery is applied by an inverter to raise the voltage up to 220V or 380V for general electronic devices. e.g. when there is no wind and you use an electronic device and if the amount of electricity you use is over the battery capacity, the charge?discharge
In general, the electricity accumulated in DC 12V battery is applied by an inverter to raise the voltage up to 220V or 380V for general electronic devices. e.g. when there is no wind and you use an electronic device and if the amount of electricity you use is over the battery capacity, the charge?discharge controller sensor will be activated to switch over the power to commercial electricity automatically. If the wind rises again and the battery is fully recharged, the sensor will be activated again to switch over the power to the battery back.
