Dear PVsyst Support Team, I am currently working on a project that involves arranging 18 PV modules (9 horizontally by 2 vertically) into a single string on uneven terrain using the zone function in PVsyst. While the modules align with the terrain as intended, I encounter simulation errors due to modules overlapping or encroaching upon each other. I understand that even a minimal spacing of 1–2 cm between modules is necessary to avoid such issues. Could you please confirm whether this overlapping issue has been addressed in PVsyst version 8? Additionally, are there alternative methods within PVsyst to effectively position modules on irregular terrain without encountering these overlap problems? Your guidance on this matter would be greatly appreciated.

When I import some pvsyst 8.x projects , I can't see them. (I can see pvsyst 8.x project at the fisrt page but can't find while i import the project.)

Hello PVSyst team and Users, Happy New Year,, I'm trying to move PVSyst 8.x version these days but a lttile bit afriad of many feautres to adjust. Back to the business, I am currently using PVSyst 7.4 version to design and simulate but once I open PVSyst 8.x version at the first page I can't see previous projects that i had worked in PVSyst 7.4. Moreover, Even some projects that i worked in PVSyst 8.x I can't see also. Can you guide me how can i see the projects ? Thank you

Hi Jeremie, Thank you for the comment, Sorry I don't understand, Could you give me more detail explanation? Mayne it would be great if you have a picture how to set it, meaning how to make editable. I'm sorry. I don't understand'Portion of cylinder'. Thank you.

Hello PVSyst team, I tried to type number at y axis, but it typed it more bigger and PVSyst program doesn't read this. Pls guide me thank you.

Plus, I'm trying to change House + 2-sided "height" in Ctrl + G pop windoe menu. Is there any way to enable to change this value ? It is written N/A. There are many object and It will take lot of time to change one by one. Pls guide me Thank you.

Moreover, I'd like to change root top floor color at once. I know how to change the color one on one but I'd like to chnage at once in Ctrl+ G option. Pls guide me thanks.

d Hello PVSyst team, I would like to change multiple subjects at once. But it seems N/A. Pls guide me. THanks

I clicked show/hide option but it just become white and can't see terrain in the top view. What if i have many images and want to match many images together ? i.e. one is PVsyst terrain image and another one is Autocad 2d batch image? Because I mostly receive 2d pv module batch. How can i use terrain with 2d batch image together? Because it is not only a problem of show/hide image but also when i can only see one object of terrain or one image becasue the image hide terrain or terrain hide image. and , I don't precisely know where is the our project site only in PVSyst terrain image. I need some more extra image to refer to know the our project site. Pls guide me. Thanks

I clicked continue application button and how can i import terrain??? I hear that there is an update that i can add terrain in PVSyst. But i can't find.

Hello I installed new version 8.0 but error message poped up like that. pls help *p.s. I didn't delete old versino.

You saved me thanksss!

Is there any tips to run the simulation? Because I succed to arrange various orientations but even small capacitiy orientation is needed to same inverter but this inverter is too oversized for this. I didn't expect this small capacity orientation.... Do you have any guide line at this situation??? Inverter size is planned for 125kW but I desized to 50kW but i can see error.

I adjusted tilt management degree and it works not thanks!!

Thank you This is helpful.

Good afternoon from Korea. Can I have a question? The Orientation update button doesn't run. So I moved to the Orientataion management tool and changed til 5degree but It seems like it`s not working. The Mesh #14 is the flat modules wich is 0degree. What can I try next? Pls help thanks.

One more question is, When I import from Sketchup, Some array is wholed or transformed as a line. Pls guide me. Thanks

Hello PVSyst Team, I'm using Sketchup to design terrain and modules at the same time. But a thing is when i try to export from Sketchup to PVSyst with 3DS files, I usually export in a two different files. One is only for modules and the other is only terrain file. And When I import two seperately , It doesn't matech well. Pls help how can i match those with.

I try to adjust "According to moducle strings". However, Error message appears. I checked define partition box, Becasue while it comes from Sketchup , every arrays are divied into one segment. So I used to set with array basis for the partition but now I can see only one segment basis defining partition. I want to adjust the electrical shading calculation losses with this situation, What can I do ? I am sorry my english is bad and It might be hard to understand. If you know any idea for this, Pls help. Thanks Swonno.

Hi Long time no see, I designed with Sketchup and imported to PVSyst with DAE file but the module is dived to one each other when it got imported to PVSyst. Here`s a problem. When I defien partition for electrical loss, I can't becasue it is small portion of size. How can I resolve this problem? Pls guide me Thanks.

Thank you for the comment, I understand calculating and adjusting snow case in soiling is hard. If you have any guide line for adjusting soiling losses without snow case for various cases, pls let me know such like factory area and island, ocean, salt farm. Thanks.

Hello PVSyst team, I would like to adjust and forecase snow soililng losses, I am planning to use Korea Weather forecast data for 20 years that Korea government provide. So, In this phase can i know how the soiling losses is calcuted or formula? I'll know annaully snowing days but I don't know how to adjust and convert to soiling losses for PVSyst. For example I know one of the korea site it snows 29 days per a year and how i can adjust to soiling losses ? (And the snow soiling losses will be combined with dust soiling losses ? I mean they are combined like plus? or just which more higher losses will be adjusted only itself?) Pls help. Thanks

Hello PVSyst team, This is the project shading window on this topic, I don't know why There is error meesge. It appears that Shed #18 doesn't be set own direction. I clicked "Update Orientation Parameters" button many times but It doesn't work. This screen is included the shed that cause error message. The Sheds which on the circular rooftop cause error message. This is the error message zoomed in picture. I already clicked Identify orentations but I still have same error message and can not proceed to simulate this project. Pls help. Thank you, Swonno

Good afternoon, Based on your tip I succeded to realized it with smiliar design. But I used some trick. Anyway, I understand what your point is, Is there any suggestion tutorial that what you told me? I mean can you give me any tutorial video link what PVSyst officially provide,? I mean what tutorial video it will be better that i watch? (I have been used this program since 6 months about, and now I want to deeply more understand how it works, like engineering conecept thing for design better way and get report propery, as a financial analysis purpose) *ps In Korea, because of the small land We mostly more care about the efficiency than other country that`s why i try to more draw detaily, we barely have land to build. But you said there are not that huge gap, I mean it affects low so thank you for notifing that info. I think it will take more less next time. Thank you , and sry for my english . Have a good weekend. Swonno

Thank you for your answer, But all of sudden I recognized that this is not a circle, but an eclipse. It seems like PVSyst doesn't support to realize this. If you have an idea pls share. Thank you.
