Agreed, but this additional efficiency manifest itself via a smaller footprint - regardless of which substrate, 100w is still 100w, thus I find the panel presenter’s conclusions a bit lacking...
That is the exact opposite of what the testing shows. Poly works better except when solar conditions are perfect. Since he did not test in ideal conditions, we have no way of knowing if mono would truly outperform poly.
The first "hints" of this were published on rvnet a lot of years ago when someone by chance bought two panels, one poly and one mono. The poly out performed in real life conditions. And yes the poly are always larger.
No matter how one cuts it, 100w is still 100w - this, the 800# Gorilla in the room...These 100w have no idea whatsoever whether they are coming from poly or mono because watts = power, thus his demonstration rings hollow...
