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.

4.We can offer you a competitive price .Because you are our potential and valued customer .

5.We ,CNBM ,has our own factory :CNBM JETION SOLAR .We can also customize according to customers' need . You can google our factory .

 

 

FAQ:Why install a Solar PV system?

There are many reasons to install a Solar PV system now:

As a low risk investment the returns of between 8-10% net are hard to beat especially during this financial downturn where bank interest rates are below inflation (i.e. money in a savings account even with interest added is actually reducing in value).

Its good for the environment. Installing a small domestic system of around 1.5 kW would provide around 1125 kWh of electricity every year, this would save around half a tonne of CO2 annually.

Electricity can be supplied at the point of use. Reducing strain on our national grid network.

The system will run silently and so will cause minimal disruption.

There is very little maintenance required for a PV system.

After the initial installation costs, there are no further fuel costs.

PV systems are modular, and can be added to at any time.

FAQ:How long will a Solar PV system last?

The MCS accreditation scheme means that all panels installed under the scheme by approved agents will continue to generate for at least 25 years. Over this time their output will diminish slightly but they should still perform at 85% at the 25 year mark according to the scheme rules. Manufacturers have invested heavily to ensure their products meet and in most cases exceed these target

Q:What is the most commonly used material for solar cells?
Because of the commercialization of solar cells. The variety of solar cells includes monocrystalline silicon solar battery, poly silicon solar cell, non crystalline silicon solar battery, there are also,cadmium, copper indium, etc.
Q:What should I know about the Crystalline silicon photovoltaic cells?
In electronics, crystalline silicon is typically the monocrystalline form of silicon, and is used for producing microchips. This silicon contains much lower impurity levels than those required for solar cells. Production of semiconductor grade silicon involves a chemical purification to produce hyperpure polysilicon followed by a recrystallization process to grow monocrystalline silicon.
Q:What is a High-efficiency electric solar cell panel?
We should first check if the power output performance are stable, if not, no matter how high the power supply would be, it is not efficient but just unsafe.
Q:What can be used as the materials for solar cells?
The thin-film absorbers
Q:What is the best way to deal with surplus solar cells abandoned after burning?
Unfortunately abandoned solar cells are not easy to recycle. Only the aluminium frame can be reused, and the surplus is sometimes inseparable; because the solar cell contains silicon, tin, nickel, silver metal.
Q:Do you believe you can make a solar cell by using kitchenware?
As a scientist, I think it's possible.
Q:What is sun cells technology?
Sun cells technology effectively absorbs the solar energy, and converts it into electrical energy bu using semiconductor components. Semiconductor silicon, selenium and other materials
Q:Where can I find more information about the work process of solar cells
Some scientific books specifically talk about how solar cells work in an accurate way.
Q:What is 3d solar cell? And anybody know any manufacturers?
3D’s solar cell is designed from the ground up to optimally reduce all primary losses to achieve the highest conversion efficiency.
Q:Is there any easy way to make a solar cell? I want to make a DIY solar cell with my child at home.
A solar cell is converts sunlight into the power, in this way, you can just use the silicon.
