Wind Speed

As you can imagine, there is little point having a wind turbine if you have no wind. The quickest and easiest way to get an understanding of the wind speed for the site of your proposed turbine is by using the BWEA (British Wind Energy Association) UK wind Database (NOABL). This will give an average wind speed for a 1km square area (using your postcode) at either 10m, 25m or 45m agl (Above Ground Level). It is worth stating now that even if a 1km square has a fantastic average wind speed it doesn't mean that the proposed location of your turbine will have that same average wind speed. It may be behind a tree or building or in a dip where it is sheltered from the wind - known as wind shading. Thie information from the NOABL database should only be used as a starting point and not used as the offical average wind speed for the turbine location. Follow the link below and subsequent instructions to obtain the average wind speed for your proposed site using the postcode.

Samrey use both the NOABL and the NASA Surface Meteorology databases as well as online mapping web sites to determine whether the proposed location of a turbine is viable or not if it is not possible to visit a site.

Of course the only reliable way of determining the wind speed at a location is to use an anenometer and log the data for a period of time which is something Samrey can assist with if required.
