Sun Simulation Problem


Recommended Posts


When I run the sun simulation in my PV system, the sun never lay down on the PV panels even the buildings are in an open field. So, I am having results like 83% linear loss. You can see the picture below.

Could you please guide me about the sun simulation?

Hi batu1234,

It's hard to tell on just a screenshot. A first check is to verfiy that your PV tables do not interfere with the buildings. You can try to run a "check sceene validity":


Otherwise, to better understand where your problem lies, I suggest you send us an email to support@pvsyst.com with the export of your project attached. We will be able to provide you with a more detailed answer.
