Product Description
CHINA TOP 10 manufacturer Mono and Poly 5W 20w 30w 40w 50w 100w 150w 200w 250w 260W 300w 320w solar panel 
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.
