Difficulty in energy simulation

Marta Gonçalves

Recommended Posts

I have been all morning and part of the afternoon trying to do the energy simulation of 1 project in PVSol, and whenever I request the Report, the program crashes and shuts down automatically.
The program have already sent 2 reports and the problem persists.

I need to do an energy analysis of this simulation and see no way to overcome this bug.

Hi Marta,

we are sorry that you are experiencing this error. We are looking into the issue. There is no need to open more than one thread here in the forum. And you don't need use the report function, this is intended to report inappropriate content to the moderators.

Thank you for filing the bug report. As it is a larger project, it might take a while to debug.

Thank you for your understanding, kind regards,

Dear forum users,

together with Marta we were able to track down the error and we wanted to let you know the problem and the solution.

In the PV system there was a wall mounted PV array with an inclination angle of more than 90°, that is, the modules are in fact more than vertical and already facing the ground. In these cases, our 3D shading simulation has a bug. It doesn’t calculate proper shading values, and as a consequence the yield simulation crashes.

Unfortunately we can’t fix the bug in the 3D environment now. So as a workaround we would suggest to remove this PV mounting system from the wall and place a normal PV array there, so that the inclination angle is not exceeding the 90°.


Kind regards,
