Poly 1120*665*30 Solar Panels For Houses

Polycrystalline overview and appearance
Polycrystalline solar cells also start as a silicon crystal ‘seed’ placed in a vat of molten silicon. However, rather than draw the silicon crystal seed up as with Monocrystalline the vat of silicon is simply allowed to cool. This is what forms the distinctive edges and grains in the solar cell. this process is easier and therefore less expensive.
 
Polycrystalline solar panels are now efficient
Polycrystalline cells were previously thought to be inferior to Monocrystalline because they were slightly less efficient, however, because of the cheaper method by which they can be produced coupled with only slightly lower efficiencies they have become the dominant technology on the residential solar panels market. they are also gaining inefficiency and are nearly on par with mono panels.
