Land import for solar park as 3D design


Recommended Posts

Hello support team,

I have some issue regarding my solar park design as land import from map selection option(3D).

1.As you can see in image that it we automatically consider Installation type to Mounted - Roof insted of Mounted-Open space.it means that it is consider a open space as roof!!! so how can i change it?

2.what if the land which i use has uneven surface then how can we calculate and change in our 3D design.

3.The number of panels are limited for large solar park design then what should i do if i have to design 10 MW Solar park in 3D .

I wil wait for your reply.

Thank you.

Hello Sunny,

thank you for your questions and welcome to the forum! Let me try to answer:

1) If you want to change the installation type of a module array, just right click on it, select "Edit Array" and then change it to the desired value in this dialogue:


2) At the moment, we only support even surfaces in PV*SOL. They can have a slope, however. If you paint a polygon on the map import, and then select "Extrude 3D object", then select "Arbitray Open Surface" from the options list. For this type of object you can set a slope. One extreme example here:


3) The planning in the 3D environment is capable of handling up to 7,500 mounted modules or up to 10,000 roof-parallel modules on a modern computer. A 10 MW PV power plant would have around 33,000 modules when using 300Wp modules. This is far beyond the capabilities of the 3D environment. You can try this at your own risk if you change the limitation in the ini file here:

C:\Users\YOUR_USERNAME\Documents\Valentin EnergieSoftware\PVSOL premium 2021\PVSOL.ini

Close PV*SOL, locate the elements 




and change the values to your liking. Then restart PV*SOL again. But don't be too enthusiastic, chances are that this will lead to regular crashes because of memory exceptions.

You could also either plan a substructure of the power plant, like 1 MW, and then scale the results with a factor of 10 (this you would have to do manually). Or you can design the PV plant in 2D, where the module limits don't apply.

Hope that helps, kind regards,

Hi Marin!


Regarding your number 2, I imported a terrain model (I have no need for this myself at the moment, just wanted to try it) and got it to work kind of good in 10 minutes.






I'm sure that someone else can make this much better than what I have done in this mock-up. Just wanted to show that it's possible to do and that it may be easier than step #2 if the environment is complex.

Hi Trond!

Just import a 3d model into the 3d design and tick the "use as terrain model" box.




The issue then becomes to define mounting surfaces on the terrain. You can either draw mounting surfaces or have them automatically determined (beta). You can also tinker with the auto-settings to perhaps get better results.




Hope that helps.
