Eighty percent of the world’s landmass has winds of less than 5 meters per second (m/s). This resource is now exploitable for grid-connect power generation since Appropriate Energy Power Corporation developed the SLG wind turbine specifically for the purpose of working in such low wind regimes for the grid-connect market. The SLG makes economical, efficient and effective wind power a reality to low wind areas that require distributive generation (grid boosting), mini-wind farms, irrigation, or modular grid expansions.

Appropriate Energy wind turbines are designed to function optimally in low wind speeds based on a unique and patented function principle. Field data show that Appropriate Energy wind turbines can generate more energy than any other wind turbine with the generator of the same size. Appropriate Energy wind turbines are rated at 4.5 m/s wind speed and they operate in a wide range of 2.5 m/s to 12 m/s wind speeds.

The SLG is microprocessor-controlled using in-house proprietary software. With Appropriate Energy’s patented function principle, the SLG can be customized for optimal performance to suit the wind regime of any given site.

With its simple design, the SLG wind turbine is easy to install and maintain requiring only basic infrastructure and manpower. The system can be transported at low cost to remote areas, and erected with ease by simple ground based winches. Furthermore, the simple design also means that Appropriate Energy can transfer the technology and build the wind turbines in many countries utilizing local materials and manufacturing capabilities.

KEY FEATURES:

• Patented technology and advanced proprietary control software
• Operates in low wind speeds where most other competitors cannot
• Simple design, easy and low cost to transport, install and maintain
• Possibility of technology transfer for local manufacturing
• Custom optimization available

Appropriate Energy’S PATENTED TECHNOLOGY

The Appropriate Energy variable axis function allows the rotor blade area to adjust to all wind conditions. Therefore, longer blades can be used to capture more of the potential energy from the wind.
