Wind Turbines

Options and Considerations

	Grid Connected Wind System Enjoy the benefits of utility power while reducing your electric bill every time the wind blows. Wind systems can reduce or eliminate your monthly electric bill if your location has enough wind. Wind turbines can be directly connected to the electrical grid and in most cases no batteries required! The small wind turbine Grid Tie concept is the lowest cost energy producing home system on the market today. Depending on your wind speed and turbine size, a Grid Tie system may significantly reduce or even eliminate your monthly electrical bill. Keep in mind, these systems are not for everyone. If your local by-laws do not allow the use of small systems to connect to the grid then it is likely a grid-tied wind system can not work for you. Off Grid Wind Turbine Systems If you have or are planning to build or buy a remote home, cottage or camp that is not connected to the local power utility grid a wind turbine is a great investment. A wind turbine in the 900 to 1200 watt range is a good size to run a camp or cottage all year round. For larger cottges and full time residences a larger turbine should be considered; from 2-3 KW (2000-3000 watts). When combined with a Photovoltaic solar array, forming a hybrid system, a wind turbine provides power at night or non sunny days. This type of system does require some form of battery storage to enable the turbine to function and provide power when there is no wind or the power requirements are more than the turbine is capable of generating.
	Siting Proper siting is very important to the performance and longevity of your wind turbine. A poorly sited wind turbine will bring nothing but poor performance, maintenance issues and frustration. For a wind turbine to operate effectively, it needs to be placed in good clean wind above obstructions which cause turbulence. Your site should: 1) Be free from trees and other obstructions within a minimum 250 foot radius of the site. 2) Be able to locate a tower where the top of it would be at least 20 feet above any surrounding object within that 250 foot radius. 30 In most areas the wind usually blows from one or two directions most of the time (prevailing winds). Obstructions that block areas other than the prevailing winds are not crucial.
	Determining The Wind Speed In Your Area Now that you know you have a good spot to locate your wind turbine, next we need to determine if you have enough wind. There are a number of ways to determine if you have a wind resource in your area. You need a minimum average wind speed of 9 MPH (about 4.2 M/S) for your small wind system to be practical. Looking at the trees can give you an approximate determination of wind speed. If small trees sway, the wind speed is around 20 MPH. If large branches are in motion the wind speed is greater than 25 MPH. If trees are permanently deformed by the wind, there is likely to be a good wind resource in the area.

ECO 1200 1 kW Vertical Axis Wind Turbine

Download ECO 1200 Brochure (pdf)

The Windterra ECO1200 Wind Turbine is a revolutionary Vertical Axis Wind Turbine (VAWT). Thanks to its advanced technical design, the ECO1200 is ideally suited to both rural and urban installations, generating green energy from a freely available source -- the wind! Wind generation provides a viable solution for addressing such issues as the increasing demand and cost of power, and directly addresses world environmental issues.

The advantages of the Windterra ECO1200 Vertical Axis Wind Turbine system are in its revolutionary design:

Omni-directional: The ECO1200 can instantaneously accept wind from any direction as opposed to HAWTs (Horizontal Axis Wind Turbines, which require an on-board motor to rotate the unit relative to wind direction.

Turbulent-wind friendly: The ECO1200 is easily roof mountable and is less affected by turbulent air, making ECO1200 suited for areas where houses and trees may disturb airflow.

Low rotation speed: The ECO1200 rotates up to 200rpm during normal operation and has a maximum rpm of 270.

Industry-leading annual output: The ECO1200 blade design is optimized for performance at typical lower wind speeds. The result is a higher annual output which makes the ECO1200 a cost effective choice for green energy.

All-in-one system: The ECO 1200is a complete power-generation package, including turbine, controller/inverter, and mounting system. This system can typically be installed and ready to use in four to five hours.

Roof-top mounting: The ECO1200 is designed for roof top use, eliminating the need for a pole or tower installation that significantly increase cost and complicate routine maintenance.
