Model N/S and E/W terrain at the same time?

[d_tamarkin]

Hello,

I have imported a 3D shading scene (.PVC file from PVCase) into a PVsyst simulation based on mono-facial c-Si modules and single-axis trackers.

If I model the large array as the field type "Tracking, horizontal axis N-S", can PVsyst model shading losses from both the E/W slope and the N/S slope? Or only one slope direction?

Thank you!

E-W slope can be captured. When backtracking, the N-S tilt angle must be the same for all trackers. So E-W yes, N-S no.

Thanks for the quick response @dtarin.

Am I correct in the following thinking: if the N/S slope is consistent across the entire array, some N/S shading losses will be captured. But it will be a rough approximation of the N/S losses as a single slope angle is applied to all trackers. No undulation is captured.

[dtarin]

Correct. You can use a weighted average of the N-S slopes to capture overall N-S slope, which may be a gain or loss.

I appreciate the help! And glad that PVsyst v7 has this capability.

Hi, i have exported 3D shading scene from PVcase to PVsyst 7.2.6 and it worked well even if backtracking is kept active. I have different tracking tilts (following N-S slopes of the terrain) and different E-W slopes as well.

Do you think this may captured N-S and E-W slopes on the same time?

Thanks.
