Hello PVsyst team, I am making a simulation from a site, in which I would like to import the topography of the terrain to PVsyst. I am importing csv (separates with comas) file to create a ground data (x,y,z) from an Autocad topography curves file. Pvsyt seems to recognize the file even it is sucessfully imported to a 3D Scene, however: -Continue to work with scene truns imposible. -The draw that the 3D Scene saws doesn´t match the reality. Any help ?? Thank in advance

Hi, I am dimensioning/asseting a "self-consumption" solar PV installation with already hourly consumes. With PVsyst you can simulate a weekly consumption and compare with the energy delivers in the grid and user´s consumption in monthly amount of energy. However, as I have strong diffences in electrity hourly, seasonal and weekly tariff, I would like to have a file with hourly values regarding the energy produced, users and grid energy produced. Is there a procees to save time doing this works?? Do anybody have the experience with this type of installation and have a special methodolody ??.... and wants to share with the rest humans in this forum. Thank you in advance. Manel

Hi I am trying to have a reference value of auxiliary energy losses in a medium size solar plant with.~ Do anybody have a reference value, report, study .... about that?? Best Regards

Hi Everybody, I would like to compare the inverter´s efficiency difference between a inverter inside a building or outdoor. Caused by the increasing of the thermal conditions, I have tried to simmulated these two difference. I have introduce in miscellaneous tools -> inverter temperature for nominal power evaluation -> an increasing of external ambient temperature of 5 ºC and not significant efficiency has been appreciate in the plant. Does anybody have a reference value about: -The increasing of temperature between outdoor and indoor temperature?? -The increasing of energy consumption of the Inverters fan´s. I supposed that this two parameter are high dependent of weather conditions, but it would be helpful if somebody have a reference value. Best Regards
