Visual Quality

CNBM Solar sorts cells into four blue color classes and clearly labels them on packaging and shipping documents.

Color uniformity within cells are closely monitored and controlled.

Gives modules a high quality look and feel.

CNBM Solar sets high visual quality standards, screening more than 25 visual criteria.

Performance in High Temperature

CNBM Solar cells produce optimal power output even in high temperature conditions.

Temperature coefficients average 0.1% per °C lower than the competition. This means 3% less power degradation when cell surface temperature increases from 25°C to 55°C.

Performance in Low Light

CNBM Solar Cells perform exceptionally well even in low light.

CNBM Solar A-grade and B-grade cells are screened for shunt resistance.

Higher shunt resistance can result in up to 10% higher annual energy yield for PV systems.

Low Reverse Current

CNBM Solar cells feature low reverse current at both -10V or -12V.

Reduces hot spot risk for long-term reliability.

Environmental Compliance

CNBM Solar cells are developed with environmental protection in mind.

All cells are RoHS compliant.

REACH-SVHC compliance ensures safe entry into the European market.

RoHS compliance: safe limits of Pb and no Cd found.

 

Usage and Applications of Polycrystalline Cells

 

Solar cells are often electrically connected and encapsulated as a module. Photovoltaic modules often have a sheet of glass on the front (sun up) side, allowing light to pass while protecting the semiconductor wafers from abrasion and impact due to wind-driven debris, rain, hail, etc. Our Cells can greatly improve the performance of Solar Modules.

 

 

Packaging & Delivery of Polycrystalline Cells

 

Carton Box Package and Deliver by air.  It should be noticed that it should be avoid water, sunshine and moist.

 

 

FAQ:WHAT'S THE ADVANTAGES OF CNBM?

1.CNBM is a state-owned company under jurisdiction of central goverment , one of  Fortune 500 .Just because of this ,we can get more support and resources from our government.So ,it is realiable .

2.CNBM's solar  products are high-qualified with TUV,UL,VDE,CE,ISO certificates. Our products ranges top in China.

3.Just as I mentioned in attahment ,we signed 500MW project with Urkan under the witness of our chairman Xi Jinping ,CNBM has ability to meet your large quantity needs,Our annual capacity is 1GW.

 

 

FAQ: How many kinds of solar cells can we produce?

 

•: We can supply the normal 2 kinds of solar cells, Poly 156mm*156mm and Mono125mm*125mm , and the special demension also can be produced .

 

FAQ:What's the effeciency range of the solar cells?

 

•: We can supply 16.8% to 18.9% effeciency of the solar cells.

 Cell-To-Module Performance (CTM)

1.CNBM Solar improves cell-to-module ratio by:

2.Narrowing down efficiency bin range to 0.2%.

3.Defining efficiency bins by minimal power and 97% of current at maximum power.

4.Customers can manage and control module power output distribution.

5.Customers get more value for their money.

6.Long-Term Reliability

7.High Shunt Resistance

8.Low LID (Light-Induced Degradation)

9.Frequent internal monitoring of LID.

Q:My son is very interested in solar cells recently, and keeps asking me about the structure of a solar cell. Can anybody help me answer that question?
Here is what I found from my chemistry teacher: The basic component of a solar cell is pure silicon, which is not pure in its natural state.
Q:Solar panel resistance is changed with what
To be sure that this question is very professional. Secondly, I have to answer this question: the internal resistance of solar energy, mainly reflected in the power generation, the inhibition of current. In the time of power generation,
Q:How to manufacture solar cells?
An experiment can show the whole process of manufacturing the solar cells.
Q:What is the internal structure of solar panels
Very low, but the photoelectric conversion efficiency relative to the crystalline silicon cell more than half of the point, but the low light effect is very good, in the ordinary light can also generate electricity, such as the calculator on the solar cell.
Q:What are the advantages and disadvantages of solar panels and diodes?
In the normal power supply when the diode reverse bias; only when the power reverse, the diode is biased conduction, then the diode will be short circuit after the class, and then avoid the negative voltage damage after the circuit
Q:Anybody ever heard of solar roll flexible solar panel?
Yes, I heard about that, and I used it for one year, but you really need to make sure you know how to use it well because it requires you some skills to use it properly.
Q:How much does a solar cell cost?
If you are using a solar system at home, you may find it from your electricty bill.
Q:What's the relationship between solar energy materials and solar cells?
Solar cells are used for the direct conversion in changing the light energy into electrical energy. At present, a large number of terrestrial photovoltaic systems are actually made by silicon solar cells, which can be divided into silicon, polycrystalline silicon, amorphous silicon solar cells.
Q:Where and how can I find more information of Photovoltaic Cells Solar Panels? Can anybody share more about that?
Photovoltaic cells are considered to be one of the most reliable sun power generation materials and very easy to to maintain.
Q:What is the window material in the solar cell? what's the effect?
Because the window layer near the surface, the defect is very much, if the absorption of light generated photogenerated carriers, then it is easy to die, do not contribute to the battery output, the absorption of light are wasted, reducing battery efficiency.
