Weld the positive electrode of the flexible thin-film solar panel (1) to the adjustable voltage stabilized output device (6), the electrical parameter display module (7), and the 5V stabilized voltage output device ( 8) Positive electrode, weld the negative electrode of the flexible thin film solar panel (1) to the negative electrode of the 5V regulated output device (8) and the negative electrode series port (9), and connect one end of the tinned copper tape on the negative conductive port (11) to The negative input terminal of the adjustable voltage stabilizing output device (6) and the electrical parameter display module (7); The negative series port (9), positive series port (10) and negative conduction port (11) are correspondingly welded on the module connection port circular jack pad (903); Connect the adjustable voltage stabilized output device (6), electrical parameter display module (7), 5V stabilized output device (8), negative series port (9), and positive series port through the screw holes and the base of the corresponding device. (10), the negative conduction port (11) is fixed on the surface of the flexible thin film solar panel; (3) Sub-module manufacturing process The manufacturing process of the sub-module is the same as the rest of the manufacturing process of the main module. The difference is that there is one more negative conduction port (11) and one more positive series port (10) inside the sub-module than in the main module. ), the negative electrode of the flexible thin film solar panel (1) is connected to the negative input terminal, the negative series port (9) and the negative conduction port (11) of the 5V regulated output device (8) on the sub-module, the flexible film The positive electrode of the solar panel (1) is connected to the positive series port (10) and the positive input terminal of the 5V regulated output device (8); At the same time, there is no adjustable voltage stabilizing output device (6) and adjustable voltage stabilizing device on the surface of the sub-module. The output device base (2) is not provided with the electrical parameter display module (7) and the electrical parameter display module base (3).
