  1. When using the ageing tool to model a whole asset life, PVsyst appears to be limited in the number of output files it can create. Through all of my testing, it appears that PVsyst can only create 36 output files, which means that it is not possible to model (with output files) for more than 36 years. The limitation appears to be linked to the way in which PVsyst numbers/names the files, starting at "_0" and ending at "_Z." It doesn't appear possible for PVsyst to create file names beyond this. Refer to my screenshots for further details. However, this limitation doesn't apply to the reports that can also be created from the ageing tool. My screenshots show that it produced the entire 40 years of reports from the simulation. This means that PVsyst has no issue modelling the period (i.e., greater than 36 years). It is just a file naming limitation which prevents the output files from being created. Can this be fixed in a software update for all PVsyst versions (7.0 and 8.0)?
  2. I wanted to ask what paremeter identifies the degradation of the PV modules due to the rise of module temperature (thermal stresses)? Does the ageing tool take into consideration the module temperature? And does the ageing tool provide average degradation per year differently for different module typesetting? @Michele Oliosi
  3. Hi everyone, long time PVsyst user, first post on the forums - hoping I can get some pointers here ? I'm designing a 10MWp Solar Farm for a tender and part of the formal submission requires us to give accurate generation figures for 30 years using the PVsyst Aging Tool. We may be subject to heavy fees in the future if we build the system and it doesn't hit these generation figures, so it's really important that I get this right ? I've never used this tool before, wondering where to source some of the figures, such as Imp RMS dispersion, Vmp RMS dispersion, Individual PV modules Global degrad factor, and mismatch degrad factor. I have the panel datasheet (attached), but that only seems to give the module's warranty %'s. Where would I find the other figures, do you just reach out to the panel manufacturer? Best regards, Jack CS-BiHiKu7_CS7N-MB-AG_v1.7_F43M_J1_NA.pdf
