Hello,

When 3D modelling is being carried out with Helios 3D, PVCase or similar and the layout produced by that software is imported into PVSyst, do I need to apply an electrical effect factor less than 100% when choosing according to string during the simulation?
My understanding is that a 100% electrical effect is selected when shading if very regular and something between 60-80% when shading is more distributed (far buildings, trees, etc). If I choose 70% electrical effect when simulating a 3D model imported from PVCase that already takes into account topography, obstacles etc, am I overestimating losses or should I choose 100% electrical effect?

Hope that makes sense.

Many thanks in advance.
