I am doing some basic work with SAM's bifacial modules and was wondering what is used as the general efficiency of the backside compared to the frontside? Thanks.

Hi Dominic,

The "bifaciality" input is the ratio of rear-side efficiency to front-side efficiency, so the backside efficiency depends on the value you provide. The default value is 0.7, which is reasonable for current bifacial modules.

For more details, see the publications listed under "Bifacial Modules" on the PV Publications page of the SAM website:

Best regards,
Paul.
