I am trying to import meteo data from PVGIS of some locations in France, near the Greenwich Meridian (Longitudes 0º 0' 0") and the importing is not working because PSYST is asking to define a longitude and it's not possible to introduce manually because PVsyst is not getting the 0º 0' 0" longitude coordinates from the PVGIS copied data, accordingly to the importing method for the PVGIS data source. Can someone help me with this topic? Many thanks in advance for your support. JR
