Photovoltaic WIND Turbine
Photovoltaic and wind resources often compliment each other. At night and when the sun is low, the wind can be at its best. We offer a wide range wind generators, as well as grid connect & standalone wind turbine packages.
The wind system works in a very compact an efficient manner. The wind hits the blades and turns them. Directly behind the blades is a small generator, which converts the turning blades into power. The power is then transferred to the ground through basic wiring where you can either store it in a battery or feed it directly back into the utility grid via an interactive inverter, if available.
The power available from a wind turbine increases very rapidly with wind speed: a doubling of wind speed results in as much as an eight-fold increase in power. Therefore it is important to site wind generators in a place where the wind speed is high, as well as reasonably constant. The length of the rotor blades is also important – doubling the diameter of the circle made by the blades produces a four-fold increase in power.
The average wind speed needs to be above 18km per hour to make installing a wind turbine worthwhile. The average sized turbine used in domestic installations is between 200 and 2000 watts, and most homes will require a turbine somewhere in this range.
Mounting a wind turbine in the right site can prove difficult. You need an area with relatively high average wind speeds, and little or no turbulence (rapid fluctuations in wind speed and direction caused by buildings, trees etc). To achieve this, the turbine is normally mounted on a high tower well above all obstructions. Tower heights range from 12 metres to 30 metres or more, depending on the site. As wind speeds increase with altitude, it makes sense to get the turbine as high as practicality and budgets allow.
The easiest way to determine whetheryour residence , and especcialy your property, is suitable for the installation of a wind power of a wind power system is to use wind atlases, which provide information about the respective wind conditions. Alternatively, you can obtain information about wind conditions by ringing your nearest weather station or by making your own measurements.
