OEM 390w full black shingled solar cells

Advantages of shingled solar cells:

1、 Solve the hot spot problem, and enhance the crack resistance. Due to the unique arrangement of the laminated modules, the influence of the resistance of the welding strip on the power of the module is reduced, the minimum power loss during the module packaging process is guaranteed, and the influence of the reverse current on the hot spot effect of the module is reduced. The unique flexible connection of the laminated tile module can effectively reduce the hidden crack of the battery chip that may be caused by the module transportation and on-site installation, and control the hidden crack extension.

2、 It is applicable to high sheltered areas such as high latitude and intensive land use. Compared with other conventional components, the laminated component has lower power loss under partial shading, so it is more suitable for high latitude areas, land intensive projects and distributed projects.

3、 Increase the number of battery cells to increase the power of components. The number of dischargeable battery chips increases by 13%, and the power of the module can be increased by 15-20W. The lamination technology realizes no battery chip spacing by overlapping small battery chips. More battery chips can be placed in the same area, which effectively expands the light receiving area of the battery chip. The power generation gain can reach 18.5%, and the module efficiency can be improved to 18.81%, which is much higher than the half chip, multi grid and other component technologies: high density, space saving, The number of battery chips that can be placed on the same type of components increases by 13%.

4、 The design without main grid is adopted to reduce the shading area of metal grid line. The non main grid design of the laminated battery reduces the shading area of the metal grid line and improves the output power of the module.

5、 Serial parallel structure reduces internal resistance and shading effect. The special series parallel structure of the laminated module reduces the internal resistance and internal power consumption of the module. The parallel circuit design makes the power drop of the laminated modules have a linear relationship with the shadow shielding area. Compared with other conventional modules, it performs better under the condition of partial shading.
