Can I have my own wind turbine?
Small wind turbines are ideal for householders, communities and small businesses to use for on-site energy generation. There are a range of different types of small wind turbine models and thanks to their flexibility small wind turbines can be installed in most locations. Your individual site specifics (such as location, wind speed and local landscape) will eventually determine the best turbine type and size for your case.
How do I find out if my site is windy enough?
The actual wind speed at your site will be influenced by the local topography and any nearby obstructions such as trees or other buildings. Wind movement around buildings themselves is very fickle, so take expert advise is machines are fixed to buildings rather than free standing on a tower or mast. A site with an average wind speed of 4-5 meters per second is generally sufficient enough to make installing a small wind turbine worthwhile.
How tall are small wind turbines?
Tower height varies according to wind turbine models, but generally range from 6 to 12 meters for stand-alone machines, which are often used to provide a power source where grid power is not available. In general, the higher the tower, the higher the average wind speed that the turbine will experience and the smoother the wind. The rotor diameter of small wind turbines ranges from 1.0 to 11 meters depending on the type of a model.
What’s the best tower for me?
Tower Height
Our standard towers are 6, 9, 12, 18 and 24meters high. Certainly we can provide you the tower according to your request. In general, the higher the tower, the higher the average wind speed that the turbine will experience, and it is normally that a taller tower will generate sufficient extra energy to justify it’s additional cost, especially if there are local obstacles to be avoided.
Tower Type
Depending upon the type of the turbine, we can offer either a free-standing tower, or a guyed tower. We can also offer you hydraulic tower.
Guyed towers will tend to be used in rural locations, and have four guy wires going from the middle of the tower to concrete ground pads. They use slightly less steel than a free standing tower, but would not be considered suitable where people would be around the turbine a lot, as you don’t want to risk damage to the guy wires.
A free-standing tower or “monopole” has no guy wires, but stands on a single concrete foundation with no other supporting structure. In many cases the choice is really down to personal preference, as to which one you prefer to look at.
Do I need planning permission?
Small wind energy installations may require planning permission and you should always consult the planning officials, preferably confirmed in writing if this is needed. It is clearly good manners to discuss your plans and aspirations neighbours. Relevant factors include environmental impact, access to the site, noise and visual effects. Overall, national planning policies support the development of small scale wind energy.
What are wind turbines made of?
Wind turbine towers are generally made of steel. The blades are made of nylon, carbon fiber and glass fiber. The finish in most models is matt, to reduce reflected light.
Are wind turbines noisy?
The majority of modern small wind turbines have been designed to be very quiet. In general, the wind itself makes more noise than a wind turbine. It is most unlikely that any niose from small wind turbines will be heard at more than 50 m. If you need more detail noise data of our wind turbines, please contact with us.
Do wind turbines affect radar systems or TV reception?
Small wind turbines are unlikely to have any detrimental effects on aviation and associated radar or navigation systems. In general, turbines with small diameters are unlikely to have effects on television and radio reception. If this occurs it is likely to be highly localised and technically easy to overcome. It is also unlikely that small rooftop wind turbines will effect either mobile phone reception or fixed radio or microwave communications links.
Will small wind turbines have a ‘flicker’ from the turbine blades?
Potentially, sunlight passing through moving blades can cause a flickering effect in ‘line of sight’ directions. The possibility of the shadow from the wind turbine causing flicker should be considered at the site selection stage. It is normally possible to avoid this problem. Reflections from the blades are unlikely, especially as the coatings used on modern turbines have been selected to minimise reflection.
What about lightning strikes?
Lightning strikes do occur and can cause damage to any structure raised from the ground. However, lightning protection is a well known practice and can be applied to wind turbines as for other equipment. On some turbine models, full protection of electrical circuits is installed at manufacture. Obviously, as with other elevated structures. protection against lightning is advisablke if the turbine is installed in an area where lightning strikes are frequent. Insuring the turbine against lightning damage may be a wise precaution.
Can I use my turbine for heating?
The simple answer is yes, small wind turbines can be used for direct heating, e.g water heating as well as for battery charging and they are also ideal in remote off-grid locations. However, the energy required to heat a building is usually significantly more than the energy used in electricity, so a much larger turbine would be needed for building heat.
What happens when the wind stops blowing?
When the wind stops blowing, electricity continues to be provided by other forms of generation in an isolated system (e.g. batteries, diesel generator), and by the grid in a grid-connected system. Consequently, it is possible to have at least 10% to 20% of the country’s electrical demand met by intermittent energy sources such as wind energy, without having to make any significant changes to the way the system operates.
How do I look after my wind turbine? Wind turbine may be operated under extremely harsh environment, or meet various complicated weather. Therefore, fix- date examination and maintenance are necessary in order to keep the system operate rightly.
Do the following check every three months:
1. Check the tight wire is too loose or too tight, and adjust them, in particular in initial stage of installation and post-gale.
2. Check whether or not the wire is damaged or loose. The joints are loose and rusted or not in order to secure electrical safety.
3. Maintain the batteries following the battery manual.
4. Before storm, it is better to lay down the tower for escaping from unpredictable loss
Why does not my electro-equipment work after connected to inverter?
Check the dump energy. If the energy is not enough, the system will not operate normally; if the energy is enough, please check the connecting wire between batteries and inverter is correct.
Why can not the batteries be charged?
Check whether or not the rotor is rolling, the generator have no output at too high or too low wind speed. If the rotor is normal, disconnect the generator’s wire from batteries and controller (if there is an individual controller); check the output voltage of generator by a multi-meter. If the voltage is normal please check the batteries is ok, otherwise check the wire of generator.
Why does not the rotor roll at a normal wind speed?
If the output wire of generator is short, the rotor will not roll. Check the generator’s wire after disconnected from batteries.
How long is our generator’s lifespan?
It’s 15 years under normal care.
