  1. Hello, On your last screenshot you need to click on the "System" button. There you need to define 4 subarrays (one for each orientation) and each subarray should have the same number of modules and area than the corresponding orientation in the 3D scene. Then the error should go away. However, you should first determine if 4 orientations is the correct choice for your project. By looking at your first screenshot I see that your orientations are more or less similar. Are the different orientations only due to the slope of the ground or do you really have specific zones where all tables share the same orientation? If the different orientations are due to the slope of the ground then it would be better to have 1 orientation only (as long as all tables are on the same side of the hill) because with multiple orientations the tables belonging to the same orientation would not always be close to each other so they would not be connected to the same physical inverter and the simulation would be less realistic. To get 1 orientation only you need to increase the tolerance in your first screenshot and then click on the "Identify orientations" button. I hope this helps.
  2. Hello. Increasing the tolerance works great if you want to end up with 1 orientation only. That would give much better results than planarize the base surface. It is usually the recommended approach if your panels are on an uneven slope and they are all on the same side of the hill.
  3. Hi, the triangulation tries to connect all dots of the model, hence the lines you see. To get better accuracy you can import points for those areas as well. However since the checkbox "Enable shadow casting" is not checked it will have no impact on the simulation. Ground objects are usually used to properly position the PV panels and they are usually not casting shadows, except in specific cases. So you should be good to go.
  4. Hello. PVsyst reads the DAE file and import the content of it. You should check the scene in your source software, adjust it (add space between the tables if needed) and regenerate the DAE file to import it again in PVsyst. If you cannot (or don't want to) add more space in your source software or modify the scene in PVsyst, you can modify the following advanced parameter in "Settings > Advanced parameters": If you still encounter issues, you can deactivate those checks from the shadings scene in the menu "Tools" : Please make sure to carrefully read the warning displayed when disabling the check as disbaling it can give incorrect shadings calculation.
  5. Dear Douglas, To get rid of the error message, you can go to the advanced parameters (menu “Settings > Edit advanced parameters” from PVsyst first window), search for “spread” and modify the following value: Please keep in mind that the default value is 4° so increasing it can lead to results that are not entirely accurate, but at least you will be able to run the simulation.
  6. Hi, This error is usually displayed when you have one object of your scene that is really really far away from the other ones, making the distance between this object and the other ones too big to handle. Removing this object in your 3D software and exporting a new file will solve the problem. If you cannot solve the issue you can send us your PVC or DAE file to support@pvsyst.com and we will have a look. I hope this helps.
  7. Thank you for the additional information. The SHD file format is designed for PVsyst internal use only. So probably the way it was generated by the external software was not entirely correct. In any case, you can try to rotate objects in PVsyst directly. A first way of doing this by selecting the objects in the 3D scene and then click the rotate button. Then you can change the azimuth: Another way to do it is to click on the menu "Tools > List and management of objects". There you can also change the azimuths of some/all objects at the same time: If this doesn't solve your problem, please send us your SHD file to support@pvsyst.com so that we can have a better look.
  8. Hello. I am glad that the workaround worked. The visual issue looks like a zoom issue. You can have a look at this video on how to set the zoom back to 100%. I hope it will solve the issue:
  9. Hello, Here is a workaround to click OK. Click with the mouse on "Tree_crown" (the text itself, not the checkbox) then press two times on "Tab" on your keyboard and finally press "Enter" on your keyboard. Regarding the bug itself, I was not able to reproduce it. Are you using the latest version of PVsyst?
  10. Hi, if you are importing a PVC file or a DAE file, you can apply a 180° rotation by clicking the following checkbox:
  11. Hello. Did you check the "Terrain following trackers" checkbox in the "Frame creation" tab in PVcase? This setting should break the PVcase trackers into multiple smaller trackers for PVsyst (according to the defined gaps), placing the modules at the correct location.
  12. Hi. No this is not something that is currently possible in PVsyst.
  13. Hi, can you please send us your file by email at support@pvsyst.com so that we can have a look? Thanks in advance.
  14. Hello. Unfortunately this is currently not possible in PVsyst. However your scene doesn't look too complex so you might be able to design it from sratch in PVsyst to achieve the desired result.
  15. It looks like the total area is matching between the 3D scene and the System window but it does not match for Orientation #2 and #3. If you can't fix it you can send us your project zip file by email to support@pvsyst.com so that we can have a look.
  16. Hi, PVsyst supports several 3D file formats for import, namely *.DAE; *.3DS; *.H2P; *.PVC. You can find information about these files and the process to import them in our online help: - https://www.pvsyst.com/help/index.html?sketchup.htm - https://www.pvsyst.com/help/index.html?helios_3d.htm - https://www.pvsyst.com/help/pv-collada-file-format.htm The first link above also explains how to convert AutoCAD files to *.DAE file using Sketchup. I hope this helps.
  17. Hello, From your screenshots it looks like you are measuring the distance between two trackers and not the distance between two modules within the same tracker. If you double click on a tracker it will open its details window. There you can go to the "Trackers sizes" tab and look at the width and length of the sensitive area. Then you just need to add the size of the frame to know the full size of your trackers. I hope this helps.
  18. Hello, If you are using domes then you need to create 2 orientations (one east and one west). If you are using trackers, only one orientation is needed. When importing trackers from pvcase PVsyst will try to detect automatically the corresponding orientation. I hope this helps.
  19. Hello, PVsyst reports a discrepency between the System window (where you have only 1 subarray with all PV modules attributed to it) and the 3D scene where you have PV tables spread accross multiple orientations. The orientations detected in the 3D scene are likely due to your PV panels following the ground (so having different base slope angles). To fix this you can increase the "Tolerance" in the orientation management tool and click on the "Identify orientations" button. You can increase it until you get only 1 orientation left.
  20. You are correct. In the details window of the ground object there is a checkbox called "Enable shadow casting". If it is not checked then the ground object is ignored when calculating the shadings and collisions between the ground object and PV tables have no impact.
  21. Hello, Thank you for reaching out. We will improve this feature in one of our upcoming releases. In the meantime, you can increase the "Distance from ground" in the zone editing tool before filling your zone. This should fix your issue. I hope this helps.
  22. Hello, In the welcome screen of PVsyst you need to go to menu “Settings > Edit advanced parameters”. Then search for “spread” and modify the following value: Please keep in mind that the default value is 4° so increasing it can lead to results that are not entirely accurate, but at least you will be able to run the simulation. I hope this helps.
  23. Hello, We have the notion of central gap in PVsyst but maybe this information is not in the PVC file that you are trying to import. Can you please send us the PVC file by email at support@pvsyst.com ? This way we will check and if the information is missing we will reach out to PVCase to see how we can improve our integration in future versions. Thanks in advance.
  24. Hello, In the 3D scene you can create multiple single PV tables or multiple arrays of tables, each with the required tilt. Then you can go to "Tools > Orientations management", increase the value in "Tolerance" and click on the "Identify orientations" button until you get only one average orientation left. Then you can go to the main "System" window and you will be able to use only 1 subarray. I hope this helps.
