What is the production process of solar photovoltaic panels

　　     The production process of solar photovoltaic panels mainly includes steps such as slicing, welding, stacking, laminating, EL testing, framing, junction box assembly, clarity testing, IV testing, finished product inspection, and packaging.

     Firstly, starting from the slicing process, this step is divided into two steps: selecting and slicing. Chip selection is the process

of selecting waste chips or battery cells with different shades of color, as the performance of the battery cells directly affects the

power output of the entire component.

     The next step is the welding process, which requires equipment such as laser cutting machines, busbar welding machines, and

battery cell string welding machines. During the welding process, the battery cells will be connected together through welding

techniques.

     Next is the stacking process, which requires a template machine to stack the battery cells together according to a certain

specification and sequence.

     Next is the lamination process, which requires the use of a laminating machine to make the connection between the battery

cells more secure through high temperature and high pressure.

     Next, EL testing will be conducted, using an EL tester to test the electrical performance of the components.

     Next is the framing process, which requires an automatic framing machine to fix the welded battery cells onto the frame.

     The process of installing the junction box requires a junction box welding machine to connect the junction box to the battery

cells.

     The cleaning process is to remove stains and dust from the surface of the components, and the required equipment is the

component flipping unit.

     Next, the IV test will be conducted using an IV curve tester to measure the current voltage characteristics of the components.

     Then proceed to the finished product inspection stage, which requires a flip inspection unit to check whether the quality of

the components meets the standards.　　

     The final step is the packaging process, which involves packaging qualified products for easy transportation and sales.　　

　　     The above is the entire process of producing a solar photovoltaic panel. I don't know if you have a general understanding of the production process of solar photovoltaic panels after reading it. Multiple devices are needed to cooperate in the production process of solar photovoltaic panels. We, Zhongbu Qingtian New Energy (Hubei) Co., Ltd., are a professional manufacturer of solar photovoltaic module production line equipment with first-hand supply.
