    New error message from Near Shadings: "the axis tilts difference (6.0°) is too high."

    in Shadings and tracking

    Posted

    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:

    image.png.7272291d1b00def98cf8cafb0f03c4d8.png

     

    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.

    Import PVcase Tracker Layout with Gaps

    in Shadings and tracking

    Posted

    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.

    Multiple orientations in shadings

    in Shadings and tracking

    Posted

    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.

    bifacial error

    in Shadings and tracking

    Posted

    Dear Alberto Cerrone,

     

    To modify multiple objects at the same time, you can go to "Tools > List and management of objects". Then you select the objects you want to modify and you do the modification on one of them. It will apply to all selected objects.

     

    Regarding the bifacial issue, I suggest you send us your project at support@pvsyst.com so that we can have a better look.

     

    Thanks

    Import autocad layout into pvsyst

    in Shadings and tracking

    Dear Alberto Cerrone,

     

    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 or FBX Converter.

     

    Two important points to consider:

    - Your 2D drawings must be "surfaces" and not just "lines" in order for PVsyst to be able to convert them into PV tables.

    - Since they are 2D drawings you will then need to specify the tilt and the height from the ground in PVsyst for your PV tables.

     

    Finally, if you still encounter issues, you can have a look at the last message of this thread where a user explains how he transforms DXF 2D files and then import them in PVsyst :

    https://forum.pvsyst.com/topic/2202-import-scene-from-cad/

     

    I hope this helps.

    How to change system kind from Tables on a building to Sheds on ground ?

    in How-to

    Posted

    Hi,

    This description is generated by PVsyst depending on the layout of your 3D scene, mostly based on the kind and the altitude of your PV panels.

    Check your 3D scene to make sure that they are all properly placed. In case you have a doubt you can send us your project at support@pvsyst.com and we will have a look to why there is this description.

    If you want to change it manually you can also go to the "Report options", in the "Final report option" tab and modify the text in the "System kind" section.

    I hope this helps.

    Layout importing from CAD file

    Dear Mohamed1298,

     

    Thank you for reaching out. 

     

    PVsyst supports several 3D file formats, namely *.DAE; *.3DS; *.H2P; *.PVC.

    You can find information about these files 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

     

    For topography it is also possible to import into PVsyst a *.CSV file as described here: https://www.pvsyst.com/help/index.html?csv_ground_data.htm

    Finally you can download the topography online and import it using this step by step guide:

    https://forum.pvsyst.com/topic/3209-how-to-import-a-ground-topography-from-googleearth/#comment-8773

     

    For more interactive content about this topic you will find an explanatory video on our YouTube channel: https://youtu.be/is44ZnQtOx0

     

    Regarding filling the 3D scene with tables, you can have a look at our zone tool here: https://www.pvsyst.com/help/index.html?zones_of_tables.htm

     

    I hope this helps.

    Tracking zone with Imported topography

    in Shadings and tracking

    Posted

    Hi Mohammed,

    To achieve what you want you will need to create multiple zones on the rounded terrain. Using only one zone will not allow you to have multiple orientations without moving the tables after filling the zone.

    Regarding the automatic altitude, PV tables can sometimes penetrate the ground on complex topography. When filling the zone you can increase the "Distance from ground" to avoid this issue.

    Regards,

    Stéphane

    Problems in 3D Simulation

    in Problems / Bugs

    Posted

    Dear Zack,

    You need to make sure that the modules area are the same (or almost the same) for each orientation in the "System" window and in the shadings scene. Also you can try to increase the tolerance (top right in your last screenshot) before clicking again "Identify orientations" button for all PV panels to be included in the correct orientation.

    If you are still encountering issues you can send us your project at support@pvsyst.com so that we can have a closer look. 

    Regards,

    Stéphane

    Shading scene creation

    in Shadings and tracking

    Posted

    Hi websolar,

    Your scene is small and there aren't many modules so you can use a 3D field for each module. You will be able to use module layout and model electrical shadings without any issues.

    The problem with this approach arises with bigger systems for two reasons:

    • It is much slower and it can be difficult to manage many objects
    • It doesn't allow to model electrical shadings using partitions

    So for bigger systems it is recommended to use the zone tool to fill the area with large tables, or to manually define tables containing several modules.

    I hope this helps.

    Regards,

    Stéphane

    Design plant layout after having imported the topographic data

    Hi,

    When you open the 3D scene you can see on the right the list of objects that are in the scene. You can double click on an object to open its details:

    image.png.5b41463dd9648bfd0ae3d5ee2616c3e9.png

     

    In the detailed view of an object you can adjust the settings about the shadows casting of this object :

    Design plant layout after having imported the topographic data

    Hi,

    To place the panels on the land you have several options, like creating them manually from the PVsyst menu, creating a zone and filling it with PV fields or importing the panels from another software.

    Once everything is set up properly you can run the simulation.

    If you want to import a ground image you can follow these help sections:

    https://www.pvsyst.com/help/index.html?ground_image.htm

    https://www.pvsyst.com/help/index.html?ground_image_control.htm

    https://www.pvsyst.com/help/index.html?ground_image_control_usage.htm

    I hope this helps.
