Photovoltaic modules are lightweight and ultra-thin. In addition to meticulous and careful production line operations to avoid damage caused by human or machine equipment, detailed questioning and inspection of incoming materials should also be carried out, and the possibility of defective materials should not be ruled out.
As a manufacturer of photovoltaic solar panels, the possibility of product defects should be eliminated from the source to ensure excellent quality of incoming materials and no shortage of edges or materials.
Corners, edges, dark patches, and broken grids are often found in the incoming materials of solar cells. The solar cells themselves have defects or defects, so how can we ensure the good performance of photovoltaic modules?
Broken corners often occur at the edges and corners of solar cell panels that are damaged due to collisions. Generally, if the incoming materials are not inspected or verified, they will flow into the production process, resulting in defective products and unnecessary production losses.
The edge collapse is also attributed to the edge coating of the incoming material falling off due to friction. Once inspected and disposed of improperly, it can flow into the production process and cause irreparable losses.
The correct and compliant treatment for corner and edge collapse is to strictly screen the incoming materials, detect the defects of the corner and edge collapse, and return them to the manufacturer for processing.
Dark films and broken grids are usually caused by raw materials. Dark films are confused from the power range, resulting in internal damage. Broken grids are caused by the manufacturer or during transportation.
For dark films and broken grids, it is equally important not to underestimate them. During the production process, especially when replacing single chips, it is important not to confuse the matching of power levels.
Additionally, it is important to strengthen the inspection of incoming materials, increase the sampling ratio, and promptly report any problems found to the supplier for handling.
