Do I need planning permission?
Planning permission may be required depends on different countries for installing wind turbines of all sizes. Please contact your local government for more info. Generally speaking, this is a relatively easy process if the turbine site is not in urban area.

How much space do I need?
This depends upon what size of turbine is installed. For a typical model KN-1500 wind turbine. It is mounted on a 7 meter tilt-up tower. The concrete base is approximately 0.8M x 0.8M x 2M deep. It needs to be in an exposed area with minimum of interruptions from buildings or trees from the prevailing wind direction. It should be mounted at least 20 Meters from nearby buildings or trees. In general a 400mm2 site should be a minimum, depending on shape and orientation to the building. A power cable from the turbine needs to be connected to the battery set or to the mains supply. There is also some electrical equipment which needs to be installed in side your house near to the incoming electrical supply.

Installation
The installation is to be regarded as permanent and consists of a tower with the turbine on top, the connecting wire to your electricity supply and the electronic control which looks after the generated electric power. Over all it will take approximately 2-3 weeks to fully install.

What kinds of tower can I choose?
According to the need, tower can also be designed to different types, such as the mast with guy wires, tilt-up tower, taper joint tower and lattice truss tower. The tower is galvanized by dipping and plastic coating for anticorrosion. The plastic coating can resist ultraviolet radiation to protect the galvanization from oxidation.

Noise level.
Noise level 65dB
Noise distribution
KN-1500 wind turbine with 7m tower
When wind speed is 8m/s, with a distance of 30m from the tower center, the noise is about 58~60dB; with a distance of 60m is about 52~54dB.
When wind speed is 12m/s, with a distance of 30m from the tower center, the noise is about 68~70dB; with a distance of 60m, the noise is about 62~64dB.

Battery charging.
If you choose the off-grid system, you will need storage batteries and some where to house them. The batteries sit between the turbine and the inverter, which turns the battery output in to standard voltage so you don? need change you appliances. When the charge voltage reaches DC60v, the wind turbine will go into the unloading and shunt; when the discharge voltage of the batteries reaches DC44v, it will automatically cut down the power supply. The whole process is automatically controlled by controller.

Where does my electricity come from when there is no wind?
This system uses batteries to store excess energy when you are producing more than you are using, the capacity of the batteries is determined by wind turbine size and your requirements.

How is the electricity generated?
The principal is that if you pass soft iron through a magnetic field then this generates an electrical impulse and energy. This happens 12 times for each time the blade rotates there by creating electricity. The amount produced is proportional to the wind speed and speed of the turbine blades.

What happens if there is a storm?
The wind turbine is designed and proved to with stand winds of up to 50m/s. The turbine has a tail vane
