PVsyst V6.81
1. Glass refractive index (n) appears to be 1.526, not 1.53 as shown in Hidden Parameters
2. It does not appear n=1.37 for EVA (in Hidden Parameters) is used for "Normal glass" or "AR coating" scenarios
3. With the following assumptions, I get the same results as PVsyst:
--No ARC
--Glass n=1.526
--No refractive index applied for EVA

--ARC n=1.29
--Glass n=1.526
