Hi all,
I'm trying to find a variable that gives the Gobal Inclined Irradiance in actual plane of array AFTER backtracking. The closest I found in PVsyst output are:
GlobInc: The problem of this one is that I understand it gives the idealised GInc if the trackers were always tracking the sun (i.e. without considering backtracking early morning or later afternoon).
GlobEff: The problem is that this gives the effective global Inc after all optical losses. I need the value BEFORE optical losses but after Backtracking.
Any advice? Basically I need the GHI transposed to the actual tilt angle, without any corrections.
Regards,
Ahmad
