FAQ

We have organized several common questions for our clients,may help you sincerely:

1.what price for each watt?

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

2.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.

3.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.

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.
Q:What is the working principle of solar panels?
The production of solar cells is mainly based on semiconductor materials, its working principle is the use of optoelectronic materials to absorb light energy after the photoelectricity in the conversion reaction, according to the different materials used, solar cells can be divided into:
Q:Can cold light make solar panels power
The drawback of solar thermal power generation is that the efficiency is low and the cost is high, At least 5 to 10 times more expensive than ordinary thermal power plants.
Q:What is the principle of solar panels to convert solar energy into electricity?
Solar cells are a pair of light response and can convert light energy into electrical devices. There are many kinds of materials to produce photovoltaic effects, such as: monocrystalline silicon, polycrystalline silicon, amorphous silicon, gallium arsenide, selenium and other copper. Their power generation principle is basically the same, now the crystal as an example to describe the process of photovoltaic power generation.P-type crystalline silicon doped with phosphorus can be N-type silicon, the formation of P-N junction.
Q:Single crystal solar panels and polycrystalline solar panels
Monocrystalline silicon cells in the laboratory to achieve the conversion efficiency of 24.7%. Ordinary commercial conversion efficiency of 10% -18%. Monocrystalline silicon solar cells because of the production process problems, generally its semi-silicon ingots for the cylindrical into, and then through the slice -> cleaning -> diffusion knot -> remove the dice -> the production of electrodes -> corrosion around -> Reflective film and other workers made of finished products. General monocrystalline silicon solar cells four corners for the fillet. Monocrystalline silicon solar cell thickness is generally 200uM-350uM thick, and now the production trend is to ultra-thin and efficient direction
Q:What is the difference between solar panels and light panels?
Crystalline silicon cell conversion rate, rich in raw materials, is a large-scale commercial production of the battery, but the crystal silicon battery brings the harm can not be ignored. Crystal silicon series of batteries have a "three high more than a" common problem. High cost, high energy consumption, high pollution, byproducts and other shortcomings.
Q:Can solar panels be connected directly to motor?
Power supply must be a number of individual battery strings, connected in parallel and tightly packaged into components.
Q:Polycrystalline solar panels are good or single crystal solar energy is good
Pre-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.
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:What is the principle of solar panels work?
optical - electrical direct conversion method is the use of photoelectric effect, the solar radiation can be directly converted into electrical energy, optical - electrical conversion of the basic device is the solar cell. The solar cell is a device that converts solar energy directly into electrical energy due to the photovoltaic effect. It is a semiconductor photodiode. When the sun shines on the photodiode, the photodiode turns the solar energy into electricity. Current. When many batteries in series or in parallel can become a relatively large output power of the solar cell array
