Number of sheds in "Unlimited sheds" — does it affect results?

[RAOUANE LAILA]

Dear PVsyst team,

In the Orientation → Unlimited sheds section, it's mentioned that the "Number of sheds" is only for visualization and does not affect simulation results.

However, I noticed that changing this number (e.g. from 5 to 12) slightly alters the energy yield and PR, even when mutual shading is disabled and all other parameters (pitch, tilt, GCR, etc.) stay the same.

Could you please clarify:

1. How should we choose or calculate the number of sheds?

2. Why does it impact the results if it's only for display?

3. Could internal parameters (like edge effects or area estimation) be influenced?

Thanks in advance for your help.

Best regards,
