About the production process of photovoltaic tiles.
1. Scribing
2. Feeding
3. Welding:Weld the interconnection strip to the main grid line on the front side of the battery (negative pole), and weld the front side of the battery cell and the back side electrodes of the surrounding cells in series with each other by means of the interconnection strip.
4. Laying and laminating: String welded battery strings are laminated together with glass and backsheet materials.
5. lamination: put the laid PV module into the lamination machine, vacuum, will be heated and melted and pressurized to the battery glass and backplane closely bonded together, and finally cooling and curing.
6. EL test: Detecting abnormal phenomena such as hidden cracks, fragments, false welding, broken grids, etc. of solar modules.
7. Framing:Use silicone to fill the gap between the aluminum frame and the cell module, and connect the frames with corner keys to increase the length of the module and enhance its service life.
8. install the junction box: use silicone to bond the junction box with the back plate of the component, the lead wires in the component will be threaded out of the back plate and connected to the internal lines in the junction box.
