Michele Oliosi Posted June 2, 2022 Share Posted June 2, 2022 Hi Jose, You can import the CSV by going to Databases > Known format. See: https://www.pvsyst.com/help/meteo_import_meteo_data.htm In the dropdown menu you should look for the correct source. If you cannot find the source, you can import the file as a custom format, so go instead to Databases > Custom file https://www.pvsyst.com/help/meteo_ascii_import.htm In the case of PVGIS I think the first option is not available I think, so go for the custom file.

herminator Posted December 13, 2022 Share Posted December 13, 2022 Hi both, I noticed that there is a significant difference between TMY and related monthly GHI values when data is downloaded by PVSYST embedded function: VALUES: And natively downloaded data from PVGIS site: Could you elaborate on this. Many thanks in advance. Regards-Maciej Link to comment Share on other sites More sharing options...
Michele Oliosi Posted December 13, 2022 Share Posted December 13, 2022 Unfortunately, last time we tried we weren't able to compare PVsyst and PVGIS TMY generation from a time series, since the PVGIS TMY file doesn't have the relative humidity. We are therefore not yet able to confirm whether they follow the ISO norm strictly or not. We will update our help in case we manage to cross validate the generation methods.
