What are the two main types of solar panels?

There are two main types of solar panel:

  1. Polycrystalline Solar Panels
  2. Monocrystalline Solar Panels

Polycrystalline solar panels are made from the fragments of silicon that are melted together to form wafers. They are less expensive comparatively and have about 18% efficiency.

Monocrystalline solar panels are made from silicon bars and cut into wafers. They have a diamond pattern. They are more expensive comparatively. Monocrystalline solar panels have the efficiency of 20%
