How to distinguish the quality of China mono solar panel components?
1. Look at the color: Generally speaking, the appearance color of China mono solar panels is blue, and it is relatively uniform light blue or sky blue. If the color of the battery board is dark and the color is different, then it must be that the workmanship is not meticulous.
2. Look at the surface: The tempered glass surface of China mono solar panels should be flat and free of foreign matter. In order to increase the production speed, some small manufacturers do not clean up the silica gel dripping on the surface of the tempered glass. If the silica gel is not cleaned, it will affect the power generation efficiency.
3. Look at the silica gel: see if the silica gel is evenly distributed around the back, and whether it is tightly penetrated into the gap between the back panel and the frame. Carefully observe whether there is any missing welding in the string welding of the cells. At the same time, it is also necessary to check whether the arrangement of the cells is regular.
4. Look at the back: see if there are bubbles and other phenomena on the back of the China mono solar panels.
5. Look at the border: Check whether the strength of the frame is even and whether the tightness is different.
6. Check the welding: Check whether there is any leakage of welding in China mono solar panels. Check whether the battery sheet is regular.
