  1. Hello @Tin, Here the documentation about CSV ground files: https://www.pvsyst.com/help/index.html?csv_ground_data.htm.
  2. Hi @ricardsaa This behavior is really strange, are you using the latest version of PVsyst (7.2.18)? Be careful also to respect the scales in meters. If you accidentally import your ground image at the wrong scale and you create a zone smaller than a PV table, no table will be created. If you continue to encounter difficulties, you can send us your project at support@pvsyst.com, and we can analyze the problem in more detail together.
  3. Hi @taahxr, This is not the recommended approach in PVsyst, as it drastically reduces software performance. Unfortunately, this is currently not possible in PVsyst. As suggested by @dtarin, you can model your PV tables directly in PVsyst, or edit them in Sketchup.
  4. Hi batu1234, It's hard to tell on just a screenshot. A first check is to verfiy that your PV tables do not interfere with the buildings. You can try to run a "check sceene validity": Otherwise, to better understand where your problem lies, I suggest you send us an email to support@pvsyst.com with the export of your project attached. We will be able to provide you with a more detailed answer.
  5. Thanks @dtarin, that's correct. Just an screenshot below to illustrate your solution:
  6. Hi Kassita, All web services used internally by PVsyst are listed here:
  7. Hello Debbie, This is not so simple. I tried to find a scenario: In the "List and management of objects" dialog (CTRL+G), select all your imported tables and change the origin to "Rectangle center": Select "East" oriented tables, and set the Azimut to -90°, and the tilt to the desired value (for example 30°): Select "West" oriented tables, and set the Azimut to 90°, and the tilt to the desired value (for example 30°): This will give you something that looks like dome structures:
  8. Hi Julmou, This is because you're using the trial version of PVsyst. Regards,
  9. Hi, Glad you found the solution to your problem. If you have any other questions, do not hesitate to consult our online help (https://www.pvsyst.com/help) or contact us by email at support@pvsyst.com.
  10. Hi Krunal, Since PVsyst is not CAD software, the tools to design and edit surfaces are limited. You can for example use the "Portion of Cylinder" tool to create a curved roof, but not sure if this suits your needs: For more complex surfaces, the best solution is to use external CAD software such as Sketchup, and import the model with a DAE or 3DS file. After that you can easily place your PV tables on the top of your roof using the auto elevation tool.
  11. Hi Jacob, Some variants can take a long time to load if they are complex and/or if they contain a big 3D scene. If you want to check if something is wrong in your project, please contact us at support@pvsyst.com with attached the exported zip file of your project.
  12. OK, I didn't understand that. So currently this is not possible, sorry. During transformation, arrays will always be ungrouped.
  13. It's really strange, I tried to reproduce the problem in 64 bit and 32 bit, but it works fine. Looks like the application freezes as soon as it tries to display the blue overlay to move the rows. Have you checked that your graphics card drivers are up to date? If you have several graphics cards, try to force the use of the second one with PVsyst: https://nvidia.custhelp.com/app/answers/detail/a_id/5035/~/run-with-graphics-processor-missing-from-context-menu%3A-change-in-process-of
  14. Hello, You're not doing anything wrong. This is just the name given by default, being array of '1' tracker. If this bothers you, you can simply rename your trackers by selecting them and right-clicking > Rename with auto-numbering:
  15. Hi Udo Z. In the shading scene construction window:
  16. For this kind of problem, I recommend that you contact our support service directly at support@pvsyst.com. Please attach the relevant files to your email so that we can test them on our side.
  17. Hi Mohamed, You can optionally model the site in the PVsyst 3D scene by importing your satellite image in the background (pay attention to the scale), and using the zone editing tool. But I think it would be necessary at least to know the model of used PV modules.
  18. Hi Garf, You're right, currently PVsyst cannot handle more than 8 orientations. You will need to group some orientations together (averaged orientations) so that you get 8 orientations max. To do this, you can use the tool for managing orientations in the 3D scene: FYI, we are currently working on a new major version of PVsyst which will allow you to have as much orientation as you want. This version is planned for this year if all goes well.
  19. Hi Raffaele, Unfortunately this is not possible. There is a way to change followers to single PV tables, but not in dome structures: Transform tracker to object: Then transform object to PV faces: I don't know if this will help you 🤷‍♂️
  20. Hello tlry75, Currently, it is not possible to copy/pasting zones directly. But you can right click on the zone in the tree view, and click on "Select all objects in group". You can then copy/paste selected PV fields on other similar rooftops:
  21. Hi Wailsalaoui, Instead of drawing a polygonal zone, draw a rectangular zone and remove the extra PV fields afterwards, like this: Regards,
  22. Some answers are given here: https://forum.pvsyst.com/topic/2667-sandia-model-database-no-longer-supported
  23. Hi Iulian, Thank you for these suggestions, I'll be sure to pass them on to the dev team. Just a note regarding the accuracy of the shading scene, it is not necessary to have precision to the nearest millimeter, as this will have very little impact on the shading loss factors. Loss differences of 1/1000 knowing the variability linked to the weather do not really make sense.
  24. Hi AJ, As you mentioned, the ground CSV files are XYZ coordinates. PVsyst axes depends on the location of your site (northern or southern hemisphere): You can find more details about the PVsyst reference system in our help: https://www.pvsyst.com/help/index.html?global_referential.htm. You can easily rotate your ground by 180 ° after importing with the rotation tool: . Just select your ground in the right tree view, and rotate it. You can also have fun modifying your XYZ coordinates from Excel.
