Where are you based, and what is the terrain like around you?

The wind generator system has two kinds, one is off-grid system and another is on-grid system. Generally, off-grid system consists of wind turbine/solar panels, microprocessor controller, battery and inverter. And the on-grid system consists of wind turbine/solar panels, a system controller and inverter

2. How to generate electricity from wind turbine?

Soft iron through high-speed rotation and cutting magnetic lines among in the magnetic field generated electrical pulse and energy， as blades rotate 12 times per time will be able to generate current, the wind turbine parts generate three-phase varies AC(alternating current) converter into DC(direct current) after through the controller, Charger controller connected with battery to supply direct current to user directly, also can be transformed the life required AC(alternating current ) through the inverter converter function. Therefore, the total how much electricity generated depends on wind speed and blade rotation speed.

3. Is my site windy enough?

Wind speed varies with time, from nothing on calm days to occasional violent gusts. If the wind speed at a site is recorded over a year, it will be seen to vary about a mean wind speed value. This is the annual mean wind speed (AMWS) and is an indication of how much wind energy is available. In Europe, the AMWS could be as low as 4 m/s (9.0 mph) for an inland site to around 8 m/s (13 mph) or higher on the most exposed sites. In general, you need an AMWS of at least 5 m/s to be able to generate a reasonable amount of energy, and ideally more than 5.5 m/s The HUANGYA turbine works well at low wind speeds at 2.5m/s, but because the energy available in the wind is a function of the cube of its speed, there is very little energy available to be harvested at wind speeds less than 3 m/s.

One thing you should do is actually measure your wind speed with an anemometer, which simply measures the wind speed. When this is connected however to a data logger, you can collect and analyse your average wind speed over a period of time. You would need to measure the wind speed for a period of at least 1 years to get a truly accurate average, as the wind speed not only varies during a year, but you can get “windy” and “calm” years, which can make a significant difference. You can however measure for a much shorter period and correlate your reading with a local weather station.

5. How much space do I need to install wind turbine?

This depends upon what size of turbine is installed. Like HY-2KW wind turbine, installation area require of approximately 0.6M x 0.6M x 1.7M deep for concrete base.

6. How much height is best for tower choose?

In general, the higher the tower, the higher the average wind speed that the turbine will experience, and it is normally the case that a taller tower will generate sufficient extra energy to justify it's additional cost, especially if there are local obstacles to be avoided. For sites where there are obstructions near the turbine, a tall tower may be needed to get the turbine above the turbulence created by nearby trees or buildings, as illustrated by the diagram to the left.
