Customer ServiceSome of this equipment can be integrated into the production line according to the wished level of automation. The photovoltaic cells are placed in a piece of equipment, called solar stringer, that interconnects the cells in a series by soldering a coated copper wire, called ribbon, on the bus bar of the cell.
The photovoltaic cells are placed in a piece of equipment, called solar stringer, that interconnects the cells in a series by soldering a coated copper wire, called ribbon, on the bus bar of the cell. This delicate operation creates the string that is the basic element that creates the electrical series in the photovoltaic module.
The process is done by attaching the box with a suitable silicone or glue on the back sheet of the module and by making the electrical connection between the bus ribbon prepared before the lamination and the cables of the junction box. At the inside of the box, you can find by-pass diodes that protect the photovoltaic module when operating.
The assembly of photovoltaic modules consists of a series of consecutive operations that can be performed by automatic machines dedicated to optimizing the single production phases that transform the various raw material in a finished product.
The first phase in a photovoltaic module manufacturing line is joining the solar cells, which is done by a solar tabber and stringer, a totally automatic machine able to optimise the very delicate phase of stringing and tabbing.
By understanding the photovoltaic module production process and to learn which machines are involved in the production of a module, gives you the knowledge to understand the points that are delicate and fundamental for the production helping you in the choice of a reliable and high-quality product.
