sarika Posted August 29, 2016 Share Posted August 29, 2016 Hello,I am working on a PVsyst simulation for a on grid PV plant. I have noticed differences across values for the IAM factor global for different versions of PVsyst.In version 6.4.1, its positive, +2% (a gain). In version 6.4.7, its negative, -2.4% (loss). Cumulatively its an effect of >4%.All the details of the project are the same. The IAM profile is provided by the manufacturer which is the same in both versions.Can you explain me what factors are responsible for such a difference?Which verison is more reliable?Thanks a lot,Sarika Link to comment Share on other sites More sharing options...
