![]() ![]() Small communities, a group of houses, or a cluster of farm buildings might use turbines that are up to 20kW in size. Households usually use wind turbines that are smaller than 5kW. If the home is connected to the local electricity network and your small wind turbine produces more power than you need, you can export the extra electricity into the grid and sell it to an electricity retailer. If your home is not connected to the grid (a stand-alone system), you will need a battery bank to store the electricity generated by the small wind turbine. Conventional petrol or diesel generators.Small wind turbines are usually combined with other energy generators, such as: Back-up powerīecause wind blows intermittently, you will need a source of back up power. Careful siting can make a difference, but as a general rule, it is difficult to get wind power performing well in urban areas. However, the wind in urban areas can be turbulent and erratic, affected by buildings, trees and other obstacles – this can result in poor energy generation. Rooftop-mounted or wall-mounted micro wind turbines are becoming more common. The wind turns the rotor blades of the turbine which then spins a shaft connected to a generator. ![]() One of the best places for wind turbines is on towers on an exposed ridgeline where they will get smoother wind flow with a higher average speed. There are many varying designs and different types available, some more suitable to built up areas. However, you are likely to need to plan for alternative back-up power. If you’re in a rural area with a strong and constant wind flow and no access to the electricity network, a small wind turbine might work for you. While large wind farms are making the most of this, small wind turbines in the right setting are well suited to generating electricity for individual households or communities.
