Product Description

Mono Solar Panel

To produce a monocrystalline silicon cells, absolutely pure semiconduction material is necessary. Monocrystalline rods are extracted from melted silicon and then sawed into thin plates.This production process guarantees a relatively high level of efficiency silicon and makes monocrystalline panels one of the most efficient, producing smaller solar cells, and therefore smaller panels. Monocrystalline works very well in bright cool conditions.

Poly Solar Panel

Polycrystalline solar panels are also made from sillicon.However,instead of using a single crystal of silicon,manufacturers melt many fragments of silicon together to form the wafers for the panel.
Polycrystalline solar panels are also referred to as "multi-crystalline"or many-crystal sillicon.
Because there are many crystals in each cell,there is to less freedom for the electrons to move.As a result,polycrystalline solar panels have lower efficiency ratings than monocrystalline panels.
