Introduction of  Poly solar panels CNBM

Polycrystalline  Solar Panels 305W With High Efficiency

CNBM Solar photovoltaic (PV) Panel 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. Monocrystalline silicon(c-Si): often made using the Czochralski process. Single-crystal wafer cells tend to be expensive, and because they are cut from cylindrical ingots, do not completely cover a square solar cell module without a substantial waste of refined silicon. Hence most c-Si panels have uncovered gaps at the four corners of the cells.

 Polycrystalline  Solar Panels 305W With High Efficiency

Feature

1.Solar Cell : High efficiency crystalline solar cell. Even if under the weak light, the solar module can produce maximum power output.

2.Tempered glass (toughened glass): Anti-reflecting coating and high transmission rate glass increase the power output and mechanical strength of solar module.

3.EVA and TPT: Using high quality EVA and TPT to prevent destroying and water.

4.Long lifetime: ≥25 years; Less power decrease.

5.Resisting moisture and etching effectively, not effected by geology.

6.The certificate issued by international authority: UL, TUV, IEC, VDE, CE.

Q:Solar panels single crystal and double crystal in the rain which is easy to use
Polycrystalline silicon solar cell production process and monocrystalline silicon solar cell almost, but the polysilicon solar cell photoelectric conversion efficiency will have to reduce a lot of its photoelectric conversion efficiency of about 12% (July 1, 2004 Japan Sharp market efficiency of 14.8% Of the world 's most efficient polysilicon solar cells).
Q:What is the working principle of solar panels?
the material is easy to industrial production and material performance and stability.
Q:What is the main material for making solar panels?
You can also according to their own needs, according to the power to buy a good package of solar photovoltaic products.
Q:Can cold light make solar panels power
The drawback of solar thermal power generation is that the efficiency is low and the cost is high, At least 5 to 10 times more expensive than ordinary thermal power plants.
Q:What is the principle of solar panels to convert solar energy into electricity?
Solar cells are a pair of light response and can convert light energy into electrical devices. There are many kinds of materials to produce photovoltaic effects, such as: monocrystalline silicon, polycrystalline silicon, amorphous silicon, gallium arsenide, selenium and other copper. Their power generation principle is basically the same, now the crystal as an example to describe the process of photovoltaic power generation.P-type crystalline silicon doped with phosphorus can be N-type silicon, the formation of P-N junction.
Q:Single crystal solar panels and polycrystalline solar panels
Monocrystalline silicon cells in the laboratory to achieve the conversion efficiency of 24.7%. Ordinary commercial conversion efficiency of 10% -18%. Monocrystalline silicon solar cells because of the production process problems, generally its semi-silicon ingots for the cylindrical into, and then through the slice -> cleaning -> diffusion knot -> remove the dice -> the production of electrodes -> corrosion around -> Reflective film and other workers made of finished products. General monocrystalline silicon solar cells four corners for the fillet. Monocrystalline silicon solar cell thickness is generally 200uM-350uM thick, and now the production trend is to ultra-thin and efficient direction
Q:Can solar panels be connected directly to motor?
Solar panels (also known as solar modules) are the core of solar power systems and the most important part of solar power systems.
Q:Composition and function of solar panels
Among them, for the electronic grade polysilicon accounted for about 55%, solar grade polysilicon accounted for 45%, with the rapid development of photovoltaic industry, solar cell demand for polysilicon growth rate higher than the development of semiconductor polysilicon, is expected to 2008 solar polysilicon
Q:The voltage and power problems of solar panels
In general, the charging voltage is 1.5 times the battery voltage as well, that is 12V battery pack, select the 18V solar panels just.
Q:What is the principle of solar panels work?
Solar power generation There are two ways of solar power generation, one is the light - heat - electricity conversion, the other is the optical - electrical direct conversion.
