[feature] Duplicate call get tiltY

Summary

TiltyY along time is recalculated in the PV_Production class while it has already been calculated in PV_Configuration_3D.

Current behavior

TiltyY along time is recalculated in the PV_Production class while it has already been calculated in PV_Configuration_3D.

Desired behavior

Compute only once, where it is useful. If the result is used at another location in the code, store it as a class attribute and reuse that instead of recomputing.
