Sunpower solar panel system solar panel kit China supplier

The type of solar panel

Monocrystalline cells are cut from a single crystal of silicon- they are effectively a slice from a crystal.
In appearance, it will have a smooth texture and you will be able to see the thickness of the slice.
These are the most efficient and the most expensive to produce. They are also rigid and must be mounted in a rigid frame to protect them.

Polycrystalline (or Multicrystalline) cells are effectively a slice cut from a block of silicon, consisting of a large number of crystals.
They have a speckled reflective appearance and again you can you see the thickness of the slice.
These cells are slightly less efficient and slightly less expensive than monocrystalline cells and again need to be mounted in a rigid frame.
