We stock both PV panels, Monocrystalline (Mono) and Polycrystalline (Poly) solar panel in our warehouse. Some may call it solar module as well.
Mostly, solar panels build in aluminum frame in silver color. The solar cell is in blue for poly module, and black for mono module. Furthermore, the all black panel uses black cell, black sheet and black frame. Is mono panels better than poly panels? Not necessarily. Now the poly cell can produce power close to mono cell already. They all carry same length warranty.
