True, but that are doing all kinds of secret sauce doping trying to up the
efficiencies too!

A side question, i thought most of the color had to do with AR coatings and not
the actual poly silicon?

That is possible. Also the sorted cells are packaged in boxes that do not
match the number needed per module (and there is always some breakage
during soldering and layup) so it is likely that they are mixing lots at
some point or during repairs of strings that get broken. Mixing higher
Many OEMS outsource cells, is it possible the cells came from different cell
companies?

Like any manufacturing process there are variations, especially solar
cells, regardless of type ( poly vs mono). It is getting harder to the
difference between poly and mono this days due to coating processes to
improve efficiency.
Cells can be sorted by output (watts) and or. Color matching.
I think it can best be described as Lots, some manufacturers actually state
that if uniform color is desired you need to match lot numbers. That would
ensure crystalline cells from the same batch and would be the most uniform in
appearance. Beyond that, it’s just hard to know until they are
6 matches
