Albedo Value for Gravel

[Mohammad Al-Hayek]

In one of our project sites, the rooftop surface is covered with gravel (dark-colored stone material).

Could you please advise on the most suitable Albedo value to use for bifacial module simulation in this scenario?

Kindly refer to the attached roof image for reference.

Finally, please consider the effect on reflection, as it is a rough surface, not a smooth surface with one color.
