CNBM Solar Panel Poly 80-330 Watt

CNBM Solar photovoltaic (PV)module such as the CNBM Solar Panel Poly 80-330 Watt is designed for large electrical power requirements. It is the optimal choice for both on-grid and off-grid power systems. CNBM Solar panel offers high performance of power per square foot of solar array. Poly- or multi-crystalline silicon (poly-Si or mc-Si): made from cast square ingots — large blocks of molten silicon carefully cooled and solidified. Poly-Si cells are less expensive to produce than single crystal silicon cells but are less efficient. US DOE data shows that there were a higher number of multi-crystalline sales than monocrystalline silicon sales.

What is a polycrystalline solar panel?

  1. Polycrystalline or Multicrystalline solar panels are solar panels that consist of several crystals of silicon in a single PV cell.
  2. Several fragments of silicon are melted together to form the wafers of polycrystalline solar panels. In the case of polycrystalline solar cells, the vat of molten silicon used to produce the cells is allowed to cool on the panel itself.
  3. These solar panels have a surface that looks like a mosaic. They have a square shape and a shining blue hue as they are made up of several polycrystalline silicon.
  4. As there are multiple silicon crystals in each cell, polycrystalline panels allow little movement of electrons inside the cells.
  5. These solar panels absorb energy from the sun and convert it into electricity.

Polycrystalline solar panel working principle

These solar panels such as CNBM Solar Panel Poly 80-330 Watt are made of multiple photovoltaic cells. Each cell contains silicon crystals which makes it function as a semiconductor device. When the photons from the sunlight fall on the PN junction (junction between N-type and P-type materials), it imparts energy to the electrons so that they can flow as electric current. 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.

Polycrystalline Solar Panel Features

  • CNBM Solar Panel Poly 80-330 Watt and other 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.
  • The acceptable maximum temperature of polycrystalline solar panels is 85 °C while the acceptable minimum temperature is -40 °C.
  • CNBM Solar Panel Poly 80-330 Watt and other polycrystalline solar panels have lower heat tolerance than monocrystalline panels. So, at higher temperatures, these solar panels have lower efficiency than others.
  • CNBM Solar Panel Poly 80-330 Watt and other polycrystalline solar panels have a higher temperature coefficient than monocrystalline panels.
  • These panels have a high power density.
  • They come with a structural frame of their own which makes mounting cheaper and simpler.

Monocrystalline solar panels vs. polycrystalline solar panels

The difference between monocrystalline and polycrystalline solar cells in Hindi is as follows.

  • As the monocrystalline solar panel is constituted of a single crystal, it provides the electrons more space to move for a better electricity flow. This is the reason behind the higher efficiency of monocrystalline panels compared to polycrystalline panels.
  • The efficiency of polycrystalline solar panels is somewhat lower, but the benefit for customers is that this option is more affordable.
  • When you seek polycrystalline solar panels for sale, the sellers may highlight the blue hue of these panels compared to the monocrystalline panels’ black hue.
  • As polycrystalline solar panel manufacturers melt multiple silicon fragments together to produce the wafers for these panels, the electrons in each cell will have less space to move. This makes the efficiency ratings of polycrystalline solar panels lower.
  • Monocrystalline solar panel prices will be relatively more compared to polycrystalline solar panels.
  • According to some industry experts, monocrystalline solar panel systems have been known to break down if they are even marginally covered in snow or dust or a part of the panel becomes shaded. Polycrystalline solar panels, on the other hand, are somewhat more resilient in these conditions.

Polycrystalline Solar Panel Advantages

The advantages of CNBM Solar Panel Poly 80-330 Watt and other polycrystalline panels are as follows.

  • CNBM Solar Panel Poly 80-330 Watt and other polycrystalline solar panel price is more affordable than monocrystalline panels due to being easier to make and using multiple silicon cells.
  • The amount of waste is less on the CNBM Solar Panel Poly 80-330 Watt and other polycrystalline panels because of the way the silicon wafers are applied to the panel.
  • They can be used with batteries and inverter technology.
  • The manufacturing process requires very few fossil fuels.
