bheilig Posted August 21, 2012 Share Posted August 21, 2012 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 Link to comment Share on other sites More sharing options...
bheilig Posted August 22, 2012 Author Share Posted August 22, 2012 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. Link to comment Share on other sites More sharing options...
André Mermoud Posted August 23, 2012 Share Posted August 23, 2012 In the 3D tool, the sheds should not be defined for each module. These are generic surfaces ("tables") for receiving sets of modules, and should be defined as big as possible for avoiding too high calculation time. Please see With my big power plant, the calculation time is prohibitive in the FAQ. Link to comment Share on other sites More sharing options...
HusseinKay Posted May 9, 2013 Share Posted May 9, 2013 Hey, This is a constant problem with PVSyst5.66. I left the near shading scene running for 3 hours the other day but it didn't work. So I had to change my shading to linear. Is there a different method or setting change that we can do to fix this issue without changing to Linear shading option? Thank you Link to comment Share on other sites More sharing options...
André Mermoud Posted June 22, 2013 Share Posted June 22, 2013 This was indeed a bug with the calculation "According to modules". I have fixed this problem for the next version 5.68, to be released by the end of June. Link to comment Share on other sites More sharing options...
