FAQ

We have organized several common questions for our clientsmay help you sincerely

what price for each watt?

it depends on the quantity, delivery date and payment terms,

what is your size for each module? can you tell me the parameter of your module?

we have different series of panels in different output, both c-si and a-si. please take the specification sheet for your reference.

Can you provide the peripheral products of the solar panels, such as the battery, controller, and inverter? If so, can you tell me how do they match each other?

Yes, we can, we have two companies for solar region, one is CNBM International, the other is CNBM engineering Co.

We can provide you not only the solar module but also Solar Cells, the off grid solar system, we can also provide you service with on grid plant.

What is your warranty system?

 Our product  performance guarantees for 25 years

12 years guarantee for workmanship

Timeliness of delivery

Quality Products certified (TÜV, UL, CE, ISO)

How do you pack your products?

We have rich experience on how to pack the panels to make sure the safety on shipment when it arrives at the destination.

Can you do OEM for us?

Yes, we can.

How long can we receive the product after purchase?

In the purchase of product within three working days, We will arrange the factory delivery as soon as possible. The pecific time of receiving is related to the state and position of customers. Commonly 7 to 10 working days can be served.

Q:What is the principle of solar panels work?
light - heat - electric conversion method through the use of solar radiation generated by thermal energy, usually by the solar collector will absorb the heat into the refrigerant refrigerant, and then drive the turbine power generation. The previous process is the light-heat conversion process; the latter process is the thermo-electrical conversion process.
Q:Single crystal solar panels and polycrystalline solar panels
monocrystalline silicon market share and a slight increase, and now the market to see the majority of single-crystal silicon cells. Monocrystalline silicon solar cell silicon crystal is very perfect, its optical, electrical and mechanical properties are very uniform, the color of the battery is mostly black or dark, especially for small pieces of small pieces of consumer products.
Q:What is the difference between solar panels and light panels?
The highest conversion efficiency in the laboratory is 24.7%, and the efficiency of the scale is 16%. Polysilicon conversion rate of 14% -15%. Amorphous silicon conversion rate of 12%. Silicon film conversion rate of 9%. Silicon solar cell is the main raw material of silicon, silicon is an extremely rich element of the earth, almost everywhere there are silicon, can be said to be inexhaustible, with silicon to create solar cells, raw materials can be described as no shortage.
Q:The voltage and power problems of solar panels
Because the MPPT controller has a wider input voltage range, it can also convert multiple voltages into current charge and better protect the battery.
Q:What is the principle and structure of solar panels?
solar controller: the role of solar controller is to control the working state of the entire system, and the battery played a charge protection, over discharge protection role. In the larger temperature difference, the qualified controller should also have the function of temperature compensation. Other additional functions such as light control switch, time control switch should be the option of the controller;
Q:How many solar panels have ah?
Classification of solar cells: Currently on the market of solar cells into amorphous silicon and crystalline silicon. Crystalline silicon can be divided into polysilicon and monocrystalline silicon. From the photoelectric conversion efficiency of the three materials is: monocrystalline silicon (up to 17%)> polysilicon (12 ~ 15%)> amorphous silicon (about 5%).
Q:What is the working principle of solar panels?
No matter what kind of material to make the battery, the general requirements for solar cell materials are
Q:Composition and function of solar panels
In addition to the quality of EVA itself, the components of the manufacturers of laminated technology is also very large, such as EVA glue degree is not up to standard, EVA and tempered glass, backplane bonding strength is not enough, will cause EVA early aging, affecting components
Q:What is the principle of solar panels to convert solar energy into electricity?
When the light is irradiated on the surface of the solar cell, a part of the photon is absorbed by the silicon material; the energy of the photon is transferred to the silicon atom, so that the electrons are moved and the free electrons are formed on both sides of the P-N junction to form a potential difference. When the circuit is used, the current will flow through the external circuit to produce a certain output power. The essence of this process is the process of converting the energy of the photon into electrical energy.
Q:Solar panels single crystal and double crystal in the rain which is easy to use
From the cost of production, than the monocrystalline silicon solar cells to be cheaper, easy to manufacture materials, saving power consumption, the total cost of production is low, so get a lot of development. In addition, the polysilicon solar cell life than monocrystalline silicon solar cells shorter. From the performance and price ratio, monocrystalline silicon solar cells also slightly better.
