Solar Panel Assembling - Backside

Backside series connecting is based on different solar panels using different templates so that the size of the back soldering groove corresponds to the size of the battery, fully integrated. Workers connect with welding junction box: Weld a box at the back of the assembly to facilitate connection to other equipment. Finally they do the component testing: Determine the output power of the battery, test its output characteristics, so that the quality level of the solar panel can be displayed.
