Abstract
The conventional small wind turbines designed for high tip speed ratio have lower performance at low wind speed region. Therefore, it is necessary to design the small wind turbine for lower tip speed ratio to attain the higher performance in the low wind speed. The authors proposed a small wind turbine with low tip speed ratio and tested it in a wind tunnel. It was obvious that the tested wind turbine has good power coefficient even in lower wind speed ranges and has low noise. This new wind turbine and PV panel are combined as a small hybrid power source named as WISH (Wind and Solar Hybrid) Box. This system is useful as the stand-alone power source, especially in developing countries.
