Bifacial difference of datasheet and PV*Sol

Hello

I need to know if there is something wrong with the bifaciality of an Akcome panel in PV*Sol database.

The panel:
CHASER-M6/144P  470W HJT Half-cut Bifacial Double Glass

In the datasheet the bifaciality is:
85% + - 5%

In PV*Sol database the bifaciality factor is:

15% 
Is it correct to use 15% in PV*Sol, or should I change the panel bifaciality to 85%.

Hello Sebastian K,

it is correct the way you think of this factor. https://help.valentin-software.com/pvsol/2022/en/calculation/pv-modules/bifacial-modules/

I searched for the datasheet and attached it. In contrast to your screenshot the Bifaciality Factor is not given in the table Operating Condition but in the table Electrical Parameters. The values 470 and 379 result to a bifaciality factor of 80.64%. In our database the manufacturer put 90%, so this seems a bit too generous.
