Question about solar combiner box.
I’m designing a small solar system for the RV roof. I have room for 3 100 watt panels which I have already ordered from Northern Arizona Wind and Sun. I know this company from when I lived in Arizona ...

Monocrystalline are supposed to be better in low light but it’s probably a toss up with some other desirable characteristic. Polycrystalline are supposedly cheaper.
It is not quite that simple.
Mono produce more power per square inch.
Poly are larger and that makes them a tiny bit better in poor light. (i.e. shade tolerant)
We had a member here iirc that had one poly and one mono from the same company with the same wattage. The poly consistently out performed the mono.
Q cells are making a poly with a reflecting surface on the bottom--that causes light to bounce back out through the active layer and gathers a bit more energy.
