Very well, thank for your immidately response.
Furthermore i would like somethnig else. Is there the opportunity to define angle or azimuth in an elementary shape like in parallilepided?
I want to position it in a roof with specific angle and azimuth.
Dear Michalis,
After adding the object to the 3D scene, you can select it, then click on rotate icon and set its tilt and azimuth as shown below:

Hello, i would like to ask about shading scene.
The distance (to this example 4 m) that named pitch N - S between 2 tables of panels is that I noted with green line, in below picture?
Dear Michalis,
Yes this is correct. The pitch corresponds to distance between counterpart points of two tables of the same field.

Dear Michalis,
After switching to "Realistic view" in the 3D scene, you can save the view for the report as shown below:
Then it will appear in the report in realistic view.

Dear everyone,
I'm new to use PVSyst so apologize to raise a rather trivial question.
I'm currently using PVSyst ver. 7.2.3, and fail to follow the direction of the manual to find PRcorr in my report.
I cannot find the Report editing window, and therefore unable to locate where the PRcorr is. Could anyone give me some instruction about how to access the data? Thanks.
Dear sir,
Please find below a screenshot showing how to edit this option:
By the way, we highly recommend you to use the latest version of PVsyst, which is 7.4.2, in order to have the last improvements and bug fixes.
Regards
Hizir.

Hello Team,
I am working on PV Syst 7.4, but I can not find "Position tables on scene" and "Position and tilt tables on scene". Is it me, or these tools have been removed?!
Thank you in advance,
Biljana
Dear Biljana,
These options have been removed since PVsyst 7.2.4 (06/07/2021) because they were redundant with "Automatic altitude"
You can select your PV tables and use "Tools>Automatic altitude" (or just right-click on the tables in the "Scene objects" list to see this option)

That‘s difficult for me
Dear Slay,
You can use the Zone tool in order to fill the imported region with PV panels:

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.
Dear sir,
Which version of PVsyst are you using and what is the format of the file imported into PVsyst?
For a more advanced investigation, you can export and send your project files to support@pvsyst.com

Dear Martin,
Indeed there seems to be an issue. Could you please export your project (PVsyst main menu "File>Export project") and send it to support@pvsyst.com so that we may investigate more in detail your issue.

Dear Andreza,
With the shading animation tool you can see the progress of shadings on your panels during a specific day of the year.
If you have defined the table partitioning in the 3D scene or the module/string attribution in the module layout, you will see them on the animation.

Dear Ricardo,
The basic reference time used in PVsyst is the legal time, which usually corresponds to the Winter Time of the country.
You can have more information about the time definition in PVsyst in this link: https://www.pvsyst.com/help/time_definition.htm
This means that the hour selection for the pricing in the economic evaluation tool correspond to your local legal clock, you don't have to perform any manual shift:
However, to take into account the time difference due to the transition to summer time, you have to set the time change dates in "Daylight saving time" of the economic evaluation as this information is not available in PVsyst and can be different for each country of the world. Thus PVsyst will automatically perform the one hour shift after this date and the correct hour will be taken into account for the pricing.

Dear Luca,
The simulation duration is displayed only when performing the simulation, this information is not stored / saved in the application.

While PVsyst is designed to run only on Windows operating systems, it's possible to emulate Windows on Mac environment through Parallels Desktop and run PVsyst on it.
However, some OpenGL driver issues on Parallels Desktop application cause Windows shutting down when generating the report in PVsyst.
This issue appeared inversion 7.3.3 of PVsyst, when some new features have been added to the single line diagram generation.
The problem is related to the virtualization environment and its drivers, as it does not occur on standard Windows machines.
In order to fix this issue and correctly generate the report in PVsyst, it's possible to disable the use of Open GL 3 on Parallels Desktop by following the below procedure:
1. Start Windows on Parallels Desktop
2. Suspend Windows from the Parallels configuration menu in the Mac top toolbar
3. Stop Windows from the same menu
4. Confirm by clicking on Stop
5. Click Configure, Boot Order, then Advanced
6. Set video.gl3=0 in Boot flags area and click on OK
7. Restart Windows in Parallels Desktop and run PVsyst. The report should now generate correctly, without causing Windows to shut down

Dear Dennis,
Could you please send your PVC file to support@pvsyst.com and describe in detail the issue so that we may investigate.

Dear Neil,
The energy sale income (first column in the financial results table of the economic evaluation tool) is obtained by multiplying the total sold energy to the grid by the kWh price (feed-in tariff) you have defined. This value can also be impacted by the module degradation (defined in the financial tab) and also the yearly feed-in tariff increase (electricity sale tab). If you export and send us your project (main menu File>Export project) to support@pvsyst.com we may investigate in detail your results.
Regards.

Hi, I have the same problem. I have tried it with windows 11 and the same thing happens. It does not happen to me in all projects, some if the report is prepared correctly. Can it happen with projects created before version 7.3.4?
Dear Marcelino,
You are kindly requested to export and send us a project causing the crash (menu "File>Export project") and log files (menu "File>Export logs") to support@pvsyst.com so that we may investigate your issue.

Dear Hizir,
thank you very much for the answer.
So the program doesn't consider the elevation of the panel from the terrain and the elevation of the terrain on the layout? The altitude value is taken only from the site of the project?
Thank you
RegardsDear Salvo,
Yes this is correct, the elevation of the panel from the terrain or the elevation of the ground object on the Z axis has no impact on the results. The altitude impact is included in the meteo data of the site.
Moreover the irradiance for the rear side and the albedo factor are not depending of the panel/ground distance drawn in the 3D scene but on the bifaciality configuration reachable from the system window for bifacial panels or from "Project settings" for the global albedo coefficient.
Regards

Dear Salvo,
The squares represent the position 0m of Z axis.
However, this is useful only to view the height differences in your scene, it does not impact the simulation result. The altitude value is taken from the site of the project. If you want to see the impact of the altitude on your yield, you have to select another site with a different altitude.
Moreover, in version 7.3.2 of PVsyst, an update has been introduced concerning the import of 3D files (*.PVC, *.DAE, *.3DS). Indeed, the imported files are now automatically brought closer to the origin of the scene (Point [0, 0, 0]).
If you don't want this offset, just uncheck the "Automatic" box and bring the coordinates back to 0.000, then your objects will have a positive Z value:

Dear Kenneth,
Your problem seems to correspond to an issue that we have corrected for the next version of PVsyst.
In order to be sure that your issue will be covered by this correction, could you please export and send your project file (PVsyst main menu "File>Export project") to support@pvsyst.com

Dear mja,
Yes transformer constant loss and auxiliaries consumption can result in a negative E-Grid value if the consumption is higher than the solar production.

Which of the use in simulation options should I choose?
1-no shadings
2-linear shadings
3-
4-
??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:

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,
Yes the simulation takes into account the shading factors based on your 3D scene
The area of the 3D fields is lower than the area of the modules defined in the subarrays.

Dear Ananthu,
The reason for this error message is that you have defined a subarray of 220kWp (982m2) for Orientation 4 in system dialog, whereas the size of your tables in the 3D scene for this orientation is 142m2. You have to increase the size of the tables in the 3D scene for Orientation 4 to 982m2, or reduce the size of your subarray for Orientation 4 in system window to 142m2 in order to have a matching.
You have a similar problem with Orientation 7 (see message in red in your screenshot). The size of the subarray defined in system window for this orientation is not matching the size of the corresponding tables in the 3D scene.
Regards.
