The anti reflective layers and texture on the panels are usually pretty good, such that then reflection is less than the area loss due to the angle.

Yes, one of the many areas of improvement of PV modules in the last couple of years has been reducing reflections from the surface of the glass and from the glass-cell boundary in panels. Also changed cell technology (n-TOPCon) helps with reflections and recombination within the cells.
