IMPORTANT NOTE
Nothing in these trials or on this website is intended to endorse or criticise any specific manufacturer of wind turbines. Both theory and practice are clear that the most significant factor affecting wind turbine performance is the location of the machine, and this trial bears this out. The purpose of the trial is to provide some initial guidance on the relative performances of turbines in different kinds of urban location, covering the maximum number of sites. In other words, where a turbine performs poorly, this is most likely due to the site not the manufacturer (and the same applies where one performs well). If you want to understand the specific benefits and features of individual makes of turbines in different contexts, please speak to the relevant manufacturers.
Encraft have free online calculators for urban wind turbines using manufacturer power curves and Rayleigh distributions of wind speed on our main website. We have found power curves are not generally a good guide to performance on urban sites (but they are often all the information customers have) so these calculators are best read as typically providing upper limits only. They are guides only.
All the sites in the trial are listed below. Each is accompanied by photos and site details when available.
