Describe the bug
A user reported an issue on version upgrade with the reported ground reflected irradiance to rear percentage reported in the loss diagram. Investigation points to issues with duplicate calls to getBackSurfaceIrradiances, but bifacial tests pass. Look into total rear irradiance used in calculations and individual rear irradiance gain and loss metrics that get reported in loss diagram.

Expected behavior
There is nothing in the most recent release that should indicate a change in these performance metrics. Make sure module aspect ratios are aligned when testing.
