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:Why can not the solar panel load directly?
Solar panels because of low power, and the output voltage is extremely unstable, not suitable for load.
Q:Solar panels single crystal and double crystal in the rain which is easy to use
At present, monocrystalline silicon solar cell photoelectric conversion efficiency of about 15%, the highest reached 24%, which is all types of solar cells in the photoelectric conversion efficiency of the highest, but the production cost is so large that it can not be a large number of extensive And commonly used. Since monocrystalline silicon is typically coated with tempered glass and waterproof resin, it is rugged and durable for up to 15 years and up to 25 years.
Q:What is the working principle of solar panels?
Based on the above considerations, silicon is the most ideal solar cell materials, which is the main reason for solar cells to silicon-based. But with the continuous development of new materials and related technology development, to other village-based solar cells are increasingly showing attractive prospects.
Q:Can cold light make solar panels power
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.
Q:What is the principle of solar panels to convert solar energy into electricity?
Silicon" is one of the most abundant materials on our planet, and since the nineteenth century scientists have discovered the semiconducting properties of crystalline silicon, it almost changed everything and even human thought. At the end of the 20th century, our lives were everywhere Crystal production and process can be divided into five steps: a, purification process b, drawing process c, slicing process d, the system of silicon Battery process e, packaging process.
Q:Can solar panels be connected directly to motor?
If the DC motor, solar panels generated by the power through the controller, and then can be used; for AC motors, solar cells to the power through the controller and inverter (DC into AC), and then can be used.
Q:Composition and function of solar panels
The demand for polysilicon is mainly from semiconductors and solar cells. According to the different requirements of purity, divided into electronic and solar level.
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.
Q:How many solar panels have ah?
But in reality, the need for solar panel power and solar charger to find a balance in the portability. It is generally believed that the minimum power of the solar charger can not be less than 0.75w, and the secondary power solar panel produces 140mA of current under standard light. In the general sunlight generated by the current at 100mA or so, if less than the secondary power charging current is too small,
