Temperature Coefficient of Monocrystalline Cells

Voc.Temp .coef.%/K：-0.351%/K                                            

Isc.Temp .coef.%/K ：  +0.035%/K

Pm.Temp. coef.%/K: -0.47%/K

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 .
