Hello everyone, it is noted that approximately since the release of the new PVsyst 8 version, when attempting to create a new site and import the PVGIS TMY v. 5.2 weather database, this attempt returns error and you are unable to move forward unless you change databases (such as meteonorm). Attempts have been made in Italy, and I don't know for other countries if the problem exists, although I think so. Please fix the problem, thank you very much, kind regards.

Hi, Some Solar Databases provide a TMY meteo data with P90 instead a value for interannual variability. I am not sure how to estimate the P90 production with this TMY P90 data. Could you please help me? I was thinking to simulate with TMY P90 meteo data as usual but then in the "Energy Management" menu set 0% for "interannual variability" and get the Energy P90 marked in the image below. This way I would be getting the uncertainties of the other sources such as PV modules, inverters, soiling and module quality loss and long term degradation. Do you have any experience or opinion on this matter? Thanks in advance. Emanuel
