The process of solar cell PV module production line

Suitable for any type of panel that derives energy from the sun: photovoltaic, solar hot water, especially photovoltaic pump systems. Suppose the panel is fixed or has a slope that can be adjusted seasonally. Panels that track the entire solar motion can get 10% (winter) to 40% (summer) more energy than fixed panels. If you are in the northern hemisphere, solar panels should always face the true south, and if you are in the southern hemisphere, the solar panels should be truly south. z purlin manufacturers. If you use the compass orientation panel, you need to correct the different differences, depending on the location. Search for “magnetic declination” on the network to find the correct angle for your location.

It is easiest to mount the solar panel in a fixed, tilted position. However, due to the high summer sun and low winter, the slope of the panel can be adjusted according to the season, and more energy can be captured throughout the year. In short, adjusting the tilt twice a year can effectively increase energy. Adjusting it four times a year can only be a little more, but if you need to optimize production in the spring and fall, it can be important.

If the solar panel will have a fixed angle of inclination, and get the most energy throughout the year. Fixed angles are convenient, but have some drawbacks. As mentioned above, the PV pump system will achieve less power than the adjustment angle. Also, if you live in a place with snow, adjust the panel to a steeper angle in winter. Snow-covered panels produce little or no power.

The process of solar cell PV module production line:

The component 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.

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.
