Muhammad Ubaid Ur Rehman Posted April 24 Share Posted April 24 Hi, Can anybody guide me about "why pv panels are going underneath the topo after importing it. I completed the design first and then imported the topo (through .csv file). Now, tables are going underneath the topo image. it will result in shading and losses. Is there any way to correct it rather than doing it from start? Link to comment Share on other sites More sharing options...
Hizir Apaydin Posted April 25 Share Posted April 25 Dear Muhammad, Tables need to be placed after importing the topography in order to follow the terrain. However, you can still reajust the position of your tables on the ground afterwards by using "Auto-altitude option" : - Select all your tables and right-click on them. Then choose "Automatic altitude" option in the contextual menu: - Click on "Set auto. altitude": - Your tables will be placed on the ground: Regards.

dtarin Posted April 25 Share Posted April 25 This will adjust the elevation of the trackers, but not the tilt. To adjust the tracker tilt to the terrain, you will need to create a zone of trackers within PVsyst, and draw the zone over the terrain. When they are generated, they will have their tilt adjusted (as long as you select the option). The other option is to use autocad or some other software to place the trackers on terrain with tilt adjusted. Link to comment Share on other sites More sharing options...

Dear Daniel, With the "Auto-altitude" tool the tilt is readjusted according to the base slope of the terrain. You can check this behaviour by opening the "List and management of objects" after using the "Auto-altitude". The tilt and azimuth are updated according to the base slope: Link to comment Share on other sites More sharing options...
furkann71 Posted May 2 Share Posted May 2 (edited) 1-I want to place a panel in the middle of an area surrounded by mountains, for this I took the ground topology from sketchcup and transferred it to pvsyst, but when I right click, the convert to ground object option does not appear for me. How Can I Solve This? 2-I want to make a panel layout in the middle of the mountains I mentioned above and simulate the closest production to reality, can I import or provide the ground topology from the sketchcup? "How to import a place topography from GoogleEarth?" Will I have to do the steps you describe at the same time? Edited May 2 by furkann71 Link to comment Share on other sites More sharing options...

Regarding the missing option "Transform to ground object", you need to update to last version of PVsyst, this is a recent option. Regards.

furkann71 Posted May 8 Share Posted May 8 If I run the simulation after making a settlement according to the topology of my land in the close shadings tab for my project, will the production estimation result be based on these shading factors, that is, will it give results by evaluating the topology factors?

Dear Furkan, "No shadings" is the default option when you haven't designed any 3D scene yet. Once designing your PV scene, you will have to choose between "Linear shading", "According to module strings" or "Detailed electrical calculations". You can find details about these modes in the following links: https://www.pvsyst.com/help/index.html?near_shadings_dialog.htm https://www.pvsyst.com/help/shadings_model.htm https://forum.pvsyst.com/topic/32-what-is-the-shading-loss-quotaccording-to-module-stringsquot/ Regards Link to comment Share on other sites More sharing options...
