solar modules

Polycrystalline or Multicrystalline solar panels are solar panels that consist of several crystals of silicon in a single PV cell. Several fragments of silicon are melted together to form the wafers of polycrystalline solar panels. In the case of polycrystalline solar panels, the vat of molten silicon used to produce the cells is allowed to cool on the panel itself.

• PERC stands for “passivated emitter and rear cell” .PERC solar panels are built with PERC cells, which have an additional layer on the back of the traditional solar cells. This additional layer allows more sunlight to be captured and turned into electricity, making PERC cells more efficient than traditional cells. PERC modules are also able to mitigate rear recombination and prevent longer wavelengths from becoming heat that would impair the cell’s performance.
