Small helical vertical axis wind turbine generator, roof-mounted VAWT for home use
Product Description
Vertical wind generator(VAWTs) are a type of wind generator where the main rotor shaft is set vertically and the main components are located at the base of the turbine. VAWTs offer a number of advantages over traditional horizontal-axis wind turbines (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.
GV-300W/500W vawt vertical 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 closer to the ground. By being closer to the ground they are easily maintained and can be installed on rooftop and similar tall structures.
The large helical type Vertical wind turbine is our GS-5kW model.
Recommend for
• Household, Garden, farm
• Telecom sites.• Rural electrification programs. Island , sentry, island, sight lighting .
The off grid 500W vertical wind generator is often used in conjunction with solar panels to provide more reliable year-round energy supply.
