High Efficiency 295-315 watts 6 x 12 Multi-crystalline or Poly-crystalline Solar Panel Taiwan

Description

Poly-crystalline Silicon Solar Cells 
 
The first solar panels based on poly-crystalline silicon, which also is known as poly-silicon (p-Si) and multi-crystalline silicon (MC-Si), were introduced to the market in 1981. Unlike mono-crystalline-based solar panels, poly-crystalline solar panels do not require the Czochralski process. Raw silicon is melted and poured into a square mold, which is cooled and cut into perfectly square wafers.



Advantages  
 

• The process used to make poly-crystalline silicon is simpler and cost less. The amount of waste silicon is less compared to mono-crystalline.

• Poly-crystalline solar panels tend to have slightly lower heat tolerance than mono-crystalline solar panels. This technically means that they perform slightly worse than mono-crystalline solar panels in high temperatures. Heat can affect the performance of solar panels and shorten their life spans. However, this effect is minor, and most homeowners do not need to take it into account.
