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.
