Mono/Poly-Crystalline Solar Panels are fabricated
from hundreds of silicon solar cells by conecting them together
then enclosing them in a glass covered metal frame

Mono-crystalline solar panels use solar cells
made from a very pure single large crystal, cut from ingots

They are usually blue-grey in color and have a fairly uniform consistency

Poly-crystalline solar panels use silicon cast
from large blocks of silicon which may contain many small crystals
