  Product Description

GREEF vertical axis Wind Turbine (VAWTs) is a type of Wind Generator where the main rotor shaft is set vertically.VAWTs offer a number of advantages over traditional horizontal-axis wind generator (HAWTs).They can be packed closer together in wind farms, allowing more in a given space.They are smaller, but rather due to the slowing effect on the air that HAWTs have, forcing designers to separate them by ten times their width. GREEF vertical Axis wind generator are rugged, quiet, light, Omni-directional, and they do not create as much stress on the support structure.They do not require as much wind to generate power, thus allowing them to be installation at urban .They are easily maintained and can be installed on rooftop and similar tall structures.

  Recommend for • Household, Garden, farm,Urban,Rooftop • Telecom sites. • Rural electrification programs. Island, sentry, island, sight lighting. The 5kw vertical axis wind turbine is often used in conjunction with Solar Panels to provide more reliable year-round energy supply.
