Polycrystalline 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.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 marketThe poly-crystalline solar panel have high charging rate of 6amps - 8amps to fill the battery of 100AH
Advanced encapsulation material with multi-layered sheet lamination to enhance cell performance and provide a long service life.
EL tested solar modules; no hot-spot heating guaranteed.
Bypass diodes minimize power drop caused by shade and ensure excellent performance in low-light environments.
TPT back sheet ensures smooth performance over a long period of time.
The process used to make polycrystalline silicon is simpler and cost less. The amount of waste silicon is less compared to monocrystalline.
Polycrystalline solar panels tend to have slightly lower heat tolerance than monocrystalline solar panels. Polycrystalline solar panels will tend to have a higher temperature co-efficient than solar modules made with mono cells. This means that as heat increased output for this type of cell will fall less. However, in practice these differences are very minor.
