I have partly solved this problem. Even though Windows reports a crash ("Not Responding"), the program is working. You just have to give it an hour or two.

Hi, I am using PVsyst to model a 1.1MW system. When I go to 'Near Shadings' and select 'According to Module Strings', I get the warning, "Please compute shading factor table". I press the button to compute, (it doesn't matter whether I choose 'linear' or 'module strings'), and the program gets through maybe three angles before it crashes. It crashes no matter what I do. I have tried modeling the array as one-shed-per-module, and I've tried modeling it with the automatic partitions. Does anyone know how to fix this? Thanks, Bret

I wouldn't bother modeling this.. it would be nearly impossible to give the host any kind of guarantee about performance. Just move the array back to where the worst-case scenario of turbine blade orientation does not affect the array at all.
