I am simulating a bifacial system with east-west configuration.
Albedo is set to 100 and modules are elevated to a height to secure rear irridiance -- not intended under real system operation.
PVSol reports on ground reflection (albedo), but no rear irridiance.
In south configuration with the same panel, I do get rear irridiance, but not in east-west.
Any special trick to east-west config?
