Sky Diffuse on Rear Side

[Aidenn]

Hi PVSyst Team,

I simulated an option for Linear Shading and According to Module string. In the reports, the only difference in the loss diagram is the Sky Diffuse on the Rear Side. Can you explain why this happen? 

The highlighted one is the " According to module string"

 

Thank you very much.

I don't know.

The discrepancy is 0.12%, on a bifacial contribution of 5%. I.e. a global discrepancy of 0.006%.  This is compltely negligible.

This is not necessarily related to the option "according to module strings". We observe sometimes little differences in the simulations, often related to rounding errors. Except in some cases, we usually don't investigate discrepancies lower than 0.1% in yearly simulations.
