Small scale windmills are very cost effective power solution comparing to solar photovoltaic systems . With speed of 8 to 10 Km/hours it cold generate 300 – 400 watt peak power. Which is very much useful for lighting system. This machine is light weight and could be installed on roof top. Wind power could be available 24 hours a day and 12mounths in year. With proper charge controller and battery banks it could a very good power source.
