How much power would i generate?
To estimate the power output, you need to establish the wind speed in your area. If you have average speeds above 5m/s (i.e. Force 3+ or 9mph+) its worth exploring a turbine in more detail. The easiest way to do this, is by looking it up on the British Wind Energy Association [BWEA] website. Please note though, that the database is based on a model and is only accurate to the nearest square kilometre, so it may be too high or too low for your actual site – in particular if you are in a hilly / urban / wooded area; and output predictions based on this database should not be treated as guarantees. For greater accuracy, you can monitor the wind speed at your site using an anemometer; but if you are going to do this you really need to do it for 3 years to account for variations between seasons and years, and anemometers cannot measure turbulence. We recommend the WS3502 which costs about £100 from [link] If your wind is not strong enough, you may want to explore PV instead.
