The process of solar cell PV module production line is also called the package line. The package is a key step in the production of solar cells. Without a good packaging process, a good battery can not produce a good component board. The battery package not only ensures the battery life, but also enhances the battery’s impact strength. The high quality and longevity of the product is the key to winning customer satisfaction, so the package quality of the component board is very important.z profile steel supplier
Process: battery testing – front welding – inspection – back series – inspection – laying (glass cleaning, material cutting, glass pretreatment, laying) – lamination – deburring (de-edge, cleaning) – frame ( Gluing, cornering, punching, framed, scrubbing glue) – welding junction box – high voltage test – component test – visual inspection – packaging into the warehouse.
How to ensure high efficiency and long life of PV modules: high conversion efficiency, high quality battery; high quality raw materials, such as: high cross-linking EVA, high bond strength encapsulant (neutral silicone resin), High transmittance, high strength tempered glass, etc.; reasonable packaging process; rigorous work style of employees. Because solar cells are high-tech products, some details in the production process, some inconspicuous problems such as wearing gloves should not wear, should be evenly painted reagents, and smashing things are the enemy of product quality, so in addition to the development In addition to reasonable production processes, the seriousness and rigor of the employees is very important.
What are the advantages of dual glass PV modules?
1.The wear resistance of the glass is very good, but also solve the problem of wind-resistant sand in the field. In the place where the wind is strong, the wear resistance of the double glass components is obvious.
2.The normal component warranty is 25 years and the dual glass PV module is 30 years.
3.With a higher life cycle power generation, 21% higher than the average component.
4.The fire rating of the double-glass component is upgraded from the C-class of the ordinary crystalline silicon component to the A-class, making it more suitable for use in residential areas, chemical plants and other areas where fire hazards are needed.
5.The water permeability of the glass is almost zero, and it is not necessary to consider the problem that water vapor enters the component and induces hydrolysis of the EVA film. The back plate of the traditional crystalline silicon solar module has a certain water permeability. The water vapor passing through the back plate makes the inferior EVA resin quickly resolve the acetic acid, which causes electrochemical corrosion inside the component, and increases the PID attenuation and snail pattern. The probability of occurrence. It is especially suitable for photovoltaic power plants in the seaside, waterside and high humidity areas.Steel Profile suppliers
6.The insulation of the glass is better than that of the backboard, which enables the double-glass component to meet higher system voltages, thereby saving the system cost of the entire power station.
7.The attenuation of the conventional components is about 0.7%, and the double glass component is 0.5%.
