Hello, I work for a photovoltaic company, and sometimes we have to use .pan files provided by manufacturers (Jinko for example). But we always observe big differences between these files and those of the PVSYST database (especially for IAM loss). Even if these files are certified by SGS laboratory. So, I would like to understand what process is used by PVSYST to certify the conformity of .pan files integrated into the database. Do have you one or more laboratories that you work with, and that we can trust ? Thank you for your response !

Hello, VOLTEC 126 VSMD 395Wc and 80 VSMP 400 Wc

Hello, I have the same problem. Can we use partitions with non-rectangular PV table ? otherwise, is there a another solution with Voltec panels to simulate electrical shading ? Thanks for your response !

Hello, I can't do my module layout with the selected PV module, having this error (image1) "The PV module 'name' is defined as "in length" with 2 cells in parallel. It cannot be used with the Module Layout calculation." In the module settings, it is defined as "in width" and not in length. Here are the informations about the module (image2) Any solution ? Thanks

Hello, I would like to know if the solar panel are tested before being integrated into the database ? For the same project, I created 2 variants, one with the .pan file of the JINKO JKM445-54HL4R-V included in your databased, and another one with a .pan file of the same panel but sent by JINKO. As you can see in the 2 graphs below, there is a huge difference between the 2 losses due to the IAM factor. I imagine that .pan files included in the database are more precise, but does it mean that we cannot trust manufacturers when they send us .pan file ? Thank you in advance for your answer !
