Reflector from ground object.

Hello. There is the posssibility to raise specific points in the 3d construction on the ground to immitate slopes. Maybe we could use this feature to create a sloped surface (immitating a reflector) in order to see if its possible to increase bifacial efficacy. Is that possible? I am currently working on my thesis to compare specific performance improvement methods for photovoltaic systems, and one of them is to add a special reflector with an albedo of 0.7 behind a PV table. This reflector is impossible to be added in PV syst and therefore I am trying to immitate it.

Hello. Unfortunately, this approach has a fundamental limitation: PVsyst treats the ground surface as a diffuse reflector, meaning it only models albedo (reflectivity intensity) but not the directionality of the reflection. A real physical reflector tilted toward the panel's rear face would redirect light in a specific direction, which cannot be accurately replicated by simply raising ground points. Therefore, this workaround would not faithfully simulate your intended reflector behavior.

Why not adjust the bifacial albedo to 0.7? If this reflector is not flat on the ground, maybe Sunsolve can simulate it.
