securing your power and your future

Wind turbines

Wind Turbines capture wind energy and convert this to electrical energy, and is capable of producing electricity at any time of the day or night. 

Turbines need consistent (non-erratic) wind speeds of around 7-8 metres per second (on average) to be a worthwhile investment. In order to assess the viability of purchasing a turbine, we recommend setting up an anemometer to get site specific data over a 12 month period (to get your seasonal averages).

For optimal conditions, the turbine needs to be placed 10m above the nearest object, although councils usually have maximum height restrictions, and minimum distance requirements from property. You will need to contact your local council to find out their exact requirements.

A wind turbine will cost anywhere from $7,000 – $20,000 installed (depending on turbine capacity, tower type, site grounds works, etc). We definitely don’t recommend getting a cheaply manufactured turbine online, as these will only cause you frustrations.

Please Note: Off-Grid Energy does not retail wind turbines individually. We use them as an additional renewable energy input for our off-grid power systems, in suitable locations. If you are looking into an off-grid system with us, we can assess your sites suitability to determine whether a wind turbine might make sense for you.

 

Horizontal-Axis Wind Turbine

Horizontal-axis turbines have a horizontally orientated motor shaft and electrical motor positioned at the top of a tower. The more common upwind versions utilise a simple wind vane in order to orientate the blades towards the changing wind direction. Horizontal-axis turbines have higher wind to power conversion efficiency and higher mounting allows access greater wind speeds.

SOMA
Soma Wind Turbines, in production since 1979 and manufactured in Australia by Sunrise Solar since 1996, are made of the highest quality materials to withstand long term wear and fatigue.

Vertical-Axis Wind Turbine

Vertical-axis turbines have a vertically orientated motor shaft and blade structure, with the gear-box and electrical generator are normally positioned near the base of the shaft. These omni-directional turbines effectively capture different prevailing winds without overly stressing the support and are easier to service due to their lower mounting height. Low starting torque and greater blade fatigue lead to a higher failure rate compared to horizontal-axis turbines.
