Multicrystalline Solar Panels

About 5 tons of polysilicon is required to manufacture 1 megawatt mw of conventional solar modules.

Multicrystalline solar panels.

Polycrystalline solar cells are cheaper to make than monocrystalline cells. This is a merit in that this solar panel has a higher temperature coefficient than those panels made from mono cells. Multicrystalline solar panels sometimes referred to as polycrystalline are made from silicon similar to their monocrystalline counterparts. Polycrystalline solar panels are also made from silicon.

However instead of using a single crystal of silicon manufacturers melt many fragments of silicon together to form the wafers for the panel. Multicrystalline panels are lower resistant to heat. This means that its efficiency in producing energy falls as temperatures rise. Poly multi crystalline solar panels are slightly cheaper to manufacture than mono crystalline solar panels.

Polysilicon is distinct from monocrystalline silicon and amorphous silicon. A polycrystalline solar panel sometimes called multicrystalline is made from polycrystalline solar cells like this one. Multicrystalline solar cells are the most common type of solar cells in the fast growing pv market and consume most of the worldwide produced polysilicon.
