Solar cell module production process

Line called packaging line components, packaging is the production of solar cells a key step in the packaging process without a good, multi-well battery is also not a good component of production boards. Battery package not only the battery life is guaranteed, but also to enhance the combat strength of the battery. Product quality and high service life is to win can be the key to customer satisfaction, so the quality of components of the package board is very important.  

 

Process is as follows:  

1, the battery test

2, positive Welding - Inspection –

3, on the back of cascading - Inspection –

4, laying (glass cleaning, material cutting, glass pre-processing, laying) –

5, laminating –

6, to flash ( to the side, cleaning) –

7, fitted border (glue, loading angle keys, punching, install box, scrub I glue) –

8, the welding junction box –

9, high-pressure test –

10, component testing -- -

11 appearance inspection, packaging and storage;

FAQ:

Q1: Why buy Materials & Equipment from OKorder.com?

A: All products offered by OKorder.com are carefully selected from China's most reliable manufacturing enterprises. Through its ISO certifications, OKorder.com adheres to the highest standards and a commitment to supply chain safety and customer satisfaction.

Q2: What is a solar PV module?

A: A solar PV module consists of many solar cells that are connected together (typically in series) and packaged in a frame (typically made of aluminum).

Q3: What are the advantages and disadvantages of monocrystalline solar PV modules?

A: Monocrystalline solar PV modules are the most efficient type of solar PV modules, with the exception of CdTe thin film solar PV modules. As a result, monocrystalline solar PV modules are more expensive when compared to almost all other types of solar PV modules.

Q4: What is the typical service life of a solar PV module?

A: The typical life of a PV module is 25 years. However, superior quality PV modules boast service lives up to 35-40 years (electrical generating capacity is often reduced, however by that point).

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 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: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: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
Used to bond fixed tempered glass and power generation (battery), transparent EVA material directly affect the quality of the component life, exposure to the air in the EVA easily aging yellow, thus affecting the component's light transmittance, thus affecting the components
Q:Polycrystalline solar panels are good or single crystal solar energy is good
Polycrystalline silicon solar cell production process and monocrystalline silicon solar cell almost, but the polysilicon solar cell photoelectric conversion efficiency will have to reduce a lot of its photoelectric conversion efficiency of about 12% (
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?
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: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,
