Wind TurbinesThere are various models and power ratings of wind turbines available and the best thing to do is to analyse your power requirements and invest in a turbine big enough to achieve this. Wind turbines are rated according to their output in Watts at a given wind speed. Be very careful when choosing a turbine as the specified wind speed may be a lot higher than the average speed at your location. The big advantage of wind power is that it can be available day and night, but there will always be periods of calm when nothing is produced. Turbines can be noisy and this should be borne in mind when deciding on the site for your installation. The factor that really decides how much power a turbine will produce is the swept area of the blades, but different blade and alternator designs can make a big difference too. Shipping cost can be quite high because turbines are often quite heavy.
