Polycrystalline Solar Panels were introduced to market in 1981. The main advantage of a polycrystalline solar panel is their lower price point.

Polycrystalline Solar Panels are also made from silicon. Instead of using a single crystal of silicon, raw silicon is melted and poured into a square mould, which is cooled and cut into perfectly square wafers.


Benefits of a Polycrystalline Solar Panel:

  1. The process used to make polycrystalline silicon is simpler and cost less.
  2. The amount of waste is also less on the panel itself because of the way the silicon wafers are applied to the panel.
  3. Polycrystalline solar panels tend to have slightly lower heat tolerance than monocrystalline solar panels.

Disadvantages of a Polycrystalline Solar Panel:

  1. The efficiency of polycrystalline-based solar panels is a little less because of lower silicon purity. 
  2. Monocrystalline solar panels tend to be more aesthetically pleasing then polycrystalline solar panels since they have a more uniform look.
