Array models are much more sophisticated than he could even understand. The simplest models use Fourier tranforms for the boundary layer effects on the lumpy terrain, and, for the wake development, turbulence levels computed from interaction of atmospheric stability, ground roughness, turbine scale, energy extraction and wind speed gradients . And it's still not complete, but tests on my ancient model in Sweden on a real 200 kW unit spinning in the Baltic breeze were not too bad
Why not put in all the effort? There's lotsa $ involved. And dont' even think of relocating a 1/2 mill $, 500 kW unit, the transfer would eat up 10 years profits!
It's a mistake to assume folks know less than you!
