Morning/afternoon discrepancies using monthly GHI

[cvernay]

Dear all,

I am wondering if there is any discrepancy in the synthetic hourly irradiation between before solar noon and after, when using monthly GHI dataset.

This question because I want to study the sensitivity of the ground orientation to the yield using monthly dataset. My feeling is that working on a full-East ground is equivalent to full-West ground. Do you think I'm correct?

Best Regards
