Sky diffuse on the rear side difference

Hi, I am currently working on the PVSyst 8.0.3 and while comparing my project with older simulations.

The sky diffuse on the rear side is less,

Update: 

In the V7, most of the time the number of sheds used for the sky diffuse on the rear side was set to 3. It meant that 2/3 of the sheds were impacted by mutual shadings, regardless of your project. 

Starting with the v8.0.0, we now use data from the system for this computation, which in most case results in a reduction of the diffuse energy on the rear side (a greater percentage of the sheds are shaded).

This value is likely to change again a little in the V8.0.6, as we fixed a minor issue.
