Domes Simulation. How Pvsyst makes the domes simulation?

[Jorge Cobra]

I have carried out a simulation with dome configuration with N-S axis, but the results have caught my attention since the Global Incident was lower than the Global Horizontal. I investigated in the hourly data and the results are strange in my opinion, since the GlobInc is higer than the Globtrp eventhough the only incident component that is higher than the trasposition component is the Diffuse component. Look at the following figure: 

I would like to know how PVsyst does the domes simulations and if this is normal.

Thanks in advance.

There was a bug that prevented variables ...Trp, BeamInc and CircInc from accumulating properly for a multi-orientation situation.
We will update this for version 8.0.8.

Thanks Michele, so the results are wrong, isn't it? Then I will wait to 8.08 version to do the simulation.

Only the intermediate results are incorrect (...Trp, BeamInc and CircInc), the other results including the final production are correct already.

[Jorge Cobra]

Just to clarify, in a domes simulation E-O with 25º tilt, the Loss diagram show a 3% of losses due to the transposition to the cell plane. This is due to the bug? the final production results are correct?

[Michele Oliosi]

No, this is correct I think. Since this is GlobInc, not affected by the bug.

[Jorge Cobra]

I think the bug is in the GlobInc, since the sum of the component are not the same as the global. I have observed that before 12 am the sum of the component is lower than the GlobInc and after 12 am higher.

[Michele Oliosi]

No, there is a problem with the components BeamInc, CircInc, etc. That's why the sum does not work. GlobInc is unaffected.
