PV Panels are going underneath the Topo

[Muhammad Ubaid Ur Rehman]

Hi,

 

Can anybody guide me about "why pv panels are going underneath the topo after importing it. I completed the design first and then imported the topo (through .csv file). Now, tables are going underneath the topo image. it will result in shading and losses. Is there any way to correct it rather than doing it from start?

[Hizir Apaydin]

Dear Muhammad,

Tables need to be placed after importing the topography in order to follow the terrain.

However, you can still reajust the position of your tables on the ground afterwards by using "Auto-altitude option" : 

- Select all your tables and right-click on them. Then choose "Automatic altitude" option in the contextual menu:

 

- Click on "Set auto. altitude":

 

- Your tables will be placed on the ground:

 

Regards.

This will adjust the elevation of the trackers, but not the tilt. To adjust the tracker tilt to the terrain, you will need to create a zone of trackers within PVsyst, and draw the zone over the terrain. When they are generated, they will have their tilt adjusted (as long as you select the option). 

The other option is to use autocad or some other software to place the trackers on terrain with tilt adjusted.

Dear Furkan, 

The procedure to create zones is described in this help page: https://www.pvsyst.com/help/zones_of_tables.htm

Check "Create tracking fields" if you want your tables to be created as trackers.

Dear Daniel,

With the "Auto-altitude" tool the tilt is readjusted according to the base slope of the terrain. You can check this behaviour by opening the "List and management of objects" after using the "Auto-altitude". The tilt and azimuth are updated according to the base slope:

1-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. How Can I Solve This?

2-I want to make a panel layout in the middle of the mountains I mentioned above and simulate the closest production to reality, can I import or provide the ground topology from the sketchcup?

Will I have to do the steps you describe at the same time?

-I did these operations, but in pvsyst, the terrain turns out to be 180 degrees, what is the reason for this, how can I solve it?

For fixed-tilt systems, the tilt and azimuth are adjusted as you have indicated. For tracker systems, tilt does not adjust.

Rotate azimuth 180 degrees.

Do I make a correct assessment by transferring the topography of the land to pvsyst with csv and then positioning and simulating it in pvsyt?
Or are there any other steps I need to take to make an accurate production estimate?

Dear Furkan,

This is a correct way to perform the simulation.

Regarding the missing option "Transform to ground object", you need to update to last version of PVsyst, this is a recent option.

How do I create a zone on the 3d terrain image that I imported with csv?

Dear Furkan,

You can find in this help page the detailed procedure to create a zone: https://www.pvsyst.com/help/zones_of_tables.htm

Just draw your zone above the imported scene and click on "Fill zone":

[furkann71]

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?

[furkann71]

Which of the use in simulation options should I choose?

1-no shadings
2-linear shadings
3-
4-
??

Dear Furkan,

Yes the simulation takes into account the shading factors based on your 3D scene

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:

How can I import weather data from outside sources?

[furkann71]

When I create a zone and place automatic pv tables on the land that I transferred with csv from outside, some pv tables do not settle, gaps occur, what could be the reason?

[furkann71]

I import my land with csv and then place it in the zone I created, then I use the automatic altitude feature, but still some pv tables seem to be embedded in the land, how can I solve this problem?

[furkann71]

I get a warning that you should not use the module layout section because it is larger than 1 mw. What should I do?

Dear Furkann71,

Please send your questions to support@pvsyst.com.

You ask a lot of different questions in the same subject, it's not how this forum works

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
