P90 from bifacial and monofacial

[zszywka]

Hello,

I have a problem with calculating the production using bifacial modules.

I created 2 identical installations:

1. with the use of monofacial panels

2. with the use of bifacial panels.

The total amount of electricity produced for monofacial is lower than for bifacial by about 6%, which is approx. On the other hand, the amount of energy for the P90 coefficient for monofacial panels is greater than for bifacial panels. Why is this happening?

All assumptions of the model are identical. Same inverters, same installation DC power, same installation losses. And yet the production of P90 for bifacial is less than P90 for monofacial. Can you help find a solution?

The P50 estimate is greater in the bifacial system?
