General selection of the standard is based on the thickness of the cells and short-circuit current to determine the thickness of PV ribbon.The width of PV ribbon is consistent with the main grids’width on the cell.The hardness of PV ribbon is generally determined by the thickness of the solar cell and the welding tools.
Manual welding process:The status of PV ribbon could be as soft as possible,soft PV ribbon can be well connected with the solar cell after welding by soldering iron.Since the stress in the welding process is very small, more soft PV ribbon can reduce the debris rate.
Automatic welding process:PV ribbon welded by automatic machine can be a little harder than manual welding. Because harder PV ribbon is good for machine to adjust the ribbon straight and pressure welding. If the ribbon is too soft, it’s easy to be out of shape in the process of welding, then reducing the rate of final products.
Our PV ribbon can meet the applied demand of the different welding process.
When we choose the Junction Box,we need to consider whether they are passed through the relevant international certification, such as TUV and UL. The Junction Box with TUV or UL means more reliable.
Not only to choose the JBs with certification, but also considering the power output of the module and safe use. Based on the choice for the JBs are the following factors: the type of module, output power, electrical properties,the number of leading line, etc.
Our JBs all through Germany TUV/ American UL certification, some also get the sun certification, with excellent quality and safety performance.The JBs can meet the needs of the ground, roof and BIPV power station project using.
