I assume that this niche is normally filled by those that build their own systems or have one designed for their specific property. This flow (Q in the power formula) can be determined by the weir method, which involves constructing a temporary dam of controlled proportions and which will be detailed in a subsequent installment, or by the float method, which is theoretically a trifle less accurate, though still quite satisfactory. Note in the drawing that in the case of a pre-existent dam, one or more measurements needed to carry around the edge of the dam are subtracted from rather than added to the total. Once the height of the dam is determined, the size of individual frames will vary depending on the contour of the gulley, those frames located at the lowest part being the largest. Although I have not exhaustively quizzed wind generator users, the basic sentiment seems to be that it is not worth the investment due to the non-laminar conditions of windthat is to say that the wind is not always blowing at a steady rate.
