Wind Generators Residential

 

Residential Wind Generators are generally small to medium size specially designed electrical power generators. These generators convert the energy of wind into electrical power using a low-speed generator. There are several different varieties and designs commercially available - as well as numerous do-it-yourself kits available for varying skill levels. For most people, it is best to hire a professional installer to size and install both the generator, and electrical interconnects.

Wind generators are a powerful and economic alternative to solar power. They fit in small areas, and produce clean, environmentally safe electricity. A wind generator will last for many years properly installed. The most common design is a large wind vane which mounted to the front of the generator, then hoisted onto a pole. The generator produces DC power, with common voltages of 12 & 24 Volts.

Nearly all wind generators these days include a controller, which is a purpose built electronic component designed to regulate the voltage and speed of the generator. The power from the controller is then fed directly into an inverter (a device to convert DC to AC, suitable for home use), or for some installations the power is stored in a bank of batteries for usage later. The later is typical for a grid-connected home owner who typically is using wind power to reduce his grid-power usage, while battery storage is typical for off-grid & remote power storage.

There are several common problems with wind generators. First, location is extremely important. Wind generators must be mounted high on poles, and located above trees and other tall objects to produce good, constant power. Additionally, not ever place is suitable for wind power - as most generators only begin to produce electricity at 9 mph. There are wind maps produced for many countries and states which can give you an idea of suitability and cost effectiveness. You may also purchase an anemometer, which can measure the wind speed for proposed localities.

In general, locations on coastal and flat planes are desired places, but wind power can work for many other places as well. Another common issue with wind generators is durability and survivability. Modern generators utilize advanced materials and specialized design to produce power not only in low wind speeds - but also during wind storms and adverse weather. Generators are now designed to operate within a safe band of speeds, and to disengage or moderate during gusts and high-speed winds.

There are two common designs, furling and tilting. A furling generator has wind vanes which "twist" or furl during high speeds. This reduces their profile into the wind, slowing the turn of the blades. A tilting generator has a gearing or torque mechanism which turns the vanes away from the direction of the wind.

Lastly, there are several issues with zoning and high restrictions, as well as noise issues with some models of wind generators. Some places restrict the height and placement of wind generators, especially in residential areas and commercial zones. Also, you will need a long area to assemble and raise the poles upon which the generator is attached. Not all generators are suitable for all areas due to noise. Flapping and whirling sounds may annoy neighbors (and even yourself). So, it is best to get a quieter system if this may be a concern. For most, it is highly advisable to hire a professional contractor to size and install your system. Additionally, you will need to hire an electrician to install your system and verify that it meets local and national electrical code standards. Also, for grid-connected installations you will need a specially-designed power-meter provided by the electric utility if you plan to "sell back" power to the utility.
