6 Meter Estimated Power Production
Note: Power production shown in the above table is from measurements of actual average turbine performance, based on the parameters and adjustments described below. Monthly and yearly averages were based on a Weibull Distribution. A description of the Weibull Distribution can be found here: http://www.windpower.org/en/tour/wres/weibull.htm
Inputs were as follows:
Weibull K factor = 2.0
Wind Shear Exponent = 0.20
Turbulence Factor = 15%
Averages shown in the above table have been derated by 20% from the calculated Weibull values to account for differences in site conditions such as altitude, turbulence, wind shear and other factors which have the potential to degrade turbine performance. Aerostar's policy is to understate turbine performance rather than overstate it. We prefer that our clients be pleased with overperformance, not dissapointed by unrealized expectations.
Because average wind velocities can have varying distributions of wind speeds, average power production is necessarily an approximation and will vary in accordance with local factors such as height, obstructions, wind shear, turbulence, etc. THE POWER PRODUCTION AT ANY SPECIFIC SITE MAY BE MORE OR LESS THAN SHOWN ON THIS TABLE. Aerostar does not publish instantaneous power curves for its turbines primarily because these curves are not representative of turbine performance under actual conditions encountered in the field. The improper use and interpretation of such curves may result in unrealistic expectations of actual turbine performance.
