Planning your wind speed monitoring project Your wind analyst or consultant will be able to advice you on this when you have collected enough wind data measurements. Of course there are techniques to improve in efficiency output from the wind and all sort of technical advances but it is a rule of thumb worth keeping in mind.įinal point to make here which ties with Locations is that in certain areas where wind is too gusty or turbulent, or even too fast, in these places it may not be the best solution to install a wind turbine with a big rotor and other smaller wind turbines will be able to take full advantage of those high wind speeds. Wind turbines are not much different, the bigger the rotor the more wind they will capture. Think about the sails of a ship, the bigger they are the more wind they capture and therefore the more energy they can harvest from it. These could have an unwanted effect not just on the increase of wind turbulences but also on the wind speed itself which could be severely reduced.Īs you can see above, the higher the hub height of the wind turbine and the better located the wind turbine, the less turbulence on the wind and more steady flow of wind. We may be in a windy area but the particular spot we may be looking at could be surrounded by obstacles like trees, houses or even towns a few miles away. Location, location, location, like the property market this point is probably one of the most important things to consider when thinking about installing a wind turbine. ![]() The 40m anemometer is showing an average wind speed of 1m/s more than the 30m one. The higher, the fewer obstacles and therefore the less turbulence on the wind and usually means higher wind speedsĪbove shows the comparison with two anemometer on the same wind mast, one at 40 meters and the other at 30 meters. This is simple, the taller the wind turbine tower the better. When thinking of installing a small wind turbine at your home or farm, there are a few things to consider, but probably the most important can be summarised in three key points: These articles try to summarise the typical questions we get everyday from end users contacting us and by no means implies you should not look a wind analyst’s assistance. I will start with small wind turbines and very basics points and little by little increase the technicality and complexity of wind site assessment which is often the bread and butter of Wind Energy Analysts. ![]() This the 1 st of a series of articles that I hope to publish in the next coming months for anyone trying to find out a bit more about wind turbines and what makes them turn.
