As an electronics enthusiast, I have been very interested in photovoltaic effects since I was in junior high school. Due to the photovoltaic technology at that time, there were not so many solar panels to choose from for DIY. In order to fulfill the author's interest when I was young. , this article introduces the assembly of a simple solar USB mobile power test product using electronic modules.
Materials needed for this article: 1
6V tempered glass solar cell, 1 TP4056 lithium battery charging module, 1 0.9-5V to 5V 600mA USB circuit board, 1 18650 battery, 1 18650 battery box, universal hole PCB board 1 piece, some wires.

lithium battery boost module
welding method:
5V boost module, TP4056 charging module, 18650 battery box button As shown in the figure, it is fixed on the universal circuit board. The output + pole and - pole of solar cell are welded to the IN+ pad and IN- pad of the TP4056 charging module respectively. The BAT- pad and BAT+ pad of the TP4056 charging module are connected using wires respectively. Weld on the + and - poles of the 18650 battery box and the + and - pole pads of the 5V boost module. Take one 18650 battery and install it in the battery box according to the polarity to form a complete solar USB mobile power supply.
