Hello,

I did a test in order to understand bifacial panel front and rear side compare with normal panel.
DC: 180 pcs x 400Wp =72kWp
AC: 60kW
Panels are mount on a concrete wall vertically.
Ground Albedo: 0%
location: Singapore
PVsyst: V6.80

Simulation_A: Normal panel, tilt angle 90 deg, Azimuth 90 deg, Annual generation 40MWh,
Simulation_B: Bifacial panel, tilt angle 90 deg, Azimuth 90 deg, Annual generation 67MWh,
Simulation_C: Bifacial panel but front side facing wall, tilt angle 90 deg, Azimuth 90 deg, Annual generation 26MWh.

my question is, why the generation of B is so high compare with A, I thought they should be similar.

Best Regards
SJ
