POLY CYRSTALLINE, FEATURES AND PRICE

PolyCrystalline or MultiCrystalline solar panels are solar panels that consist of several crystals of silicon in a single PV cell. 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. These solar panels have a surface that looks like a mosaic.

HOW POLYCRYSTALLINE SOLAR PANELS WORK

Polycrystalline solar panels have multiple photovoltaic cells. When the photons from the sunlight fall on the PN junction (between N-type and P-type materials), it imparts energy to the electrons so that they can flow as electric currents. Here, P-type materials are deficient in electrons while N-type materials have an abundance of electrons. Two electrodes are connected with the PV cells. The electrode that is on the top surface contains small wires while the electrode on the bottom is a foil-like conductor.

FEATURES OF POLYCRYSTALLINE SOLAR SYSTEM

  • Polycrystalline has high-density power.
  • They have lower heat tolerance than monocrystalline solar panels.
  • They come with a structural frame of their own.
  • Polycrystalline panels are suitable for roof-mounted arrays.
  • They are used in large solar farms to harness the power of the sun and supply electricity to nearby areas.
  • Polycrystalline solar panels are more eco-friendly than monocrystalline solar panels as they do not require individual shaping and placement of each crystal and most of the silicon is utilized during production. So, very less waste is produced.
