Solar panel assembly process

As shown in Figure 1, the battery test: Due to the random nature of the production conditions of solar cells, the performance of solar panels produced by different, so in order to effectively consistent or similar batteries together, it should be based on performance parameters Classification; battery test that is by testing the output parameters of the battery (current and voltage) of the size of its classification. To improve the utilization of the battery, to make qualified battery components.

2, the front of the welding: the bus is welded to the front of the battery (negative) of the main gate line, the busbelt is tinned copper strip, we use the welding machine can weld the spot in the form of multi-point in the main grid on-line.

3, the back of the tandem: the back of the welding is to 36 cells in series together to form a string of components, the size of the slot and the battery size corresponds to the location of the slot has been designed, different sizes of solar panels using different templates.

4, Laying Laying: The back is connected in series and qualified. After passing through the strings, glass and cut EVA, fiberglass and backplane, they are laid in a certain level and ready to be laminated.

5, component lamination: the laying of the battery into the laminating machine, through the vacuum components will be drawn out of the air, and then heated to melt the EVA to the battery, glass and back together; finally cooling the components removed.

6, Trimming: When the laminate is melted, the EVA is melted and extended outward to form a burr, so the laminate should be cut off.

As shown in FIG. 7, the frame is similar to the one provided with a glass frame; the aluminum frame is mounted on the glass component to increase the strength of the module and further seal the battery components to prolong the service life of the solar panel.

8, Welding Junction Box: Solder a box at the back of the module to facilitate the connection between the battery and other devices or batteries.

9, high voltage test: high voltage test refers to the application of a certain voltage between the frame and the electrode leads to test the voltage resistance and insulation strength of the module to ensure that the components are not damaged under harsh natural conditions.

10, component testing: The purpose of the test is to calibrate the battery output power, test its output characteristics, determine the quality level of solar panels.
