The amount of wind in the area is an essential consideration when purchasing a wind turbine. Check with the local zoning laws or the homeowners association to see what is allowed. Some turbines may be able to attach to a roof.įor both maximizing wind volume and abiding by local regulations, the placement really depends on where the property is located and whether the community has any restrictions. Wind turbines also need to be placed at a minimum height of 25 feet to catch the maximum amount of wind and provide the greatest number of benefits. Some zoning laws require that the turbine be no more than 500 feet high. There are a few factors that affect where a wind turbine is placed. Local Zoning Laws and Height Restrictions The following are all the factors to consider before making a decision. There are many factors to consider when choosing the best residential wind turbine, including the number of blades, material, height, wind-speed rating, and energy output.

HOME WIND TURBINES FOR ELECTRICITY UPGRADE
Wind energy on the Gen Less website has more information about wind turbines.Home wind turbines provide a way to independently generate power. However, your turbine will not be exposed to this wind speed all the time – typically, turbines will only generate, on average, 10-40 per cent of their rated capacity This means that if the wind only blows consistently for two hours, your 3kW turbine will only produce about 6kWh of electricity. If a model has a rated capacity of 3kW, it means it will produce 3kW of electricity per hour given a certain wind speed - the wind speed used for ratings varies between different models and manufacturers. The amount of electricity a wind turbine generates will depend on the wind speed at the site and the turbine's capacity rating. 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.
