How to DIY 

1. Apply flux on the front side along the white lines (electrodes), and then solder the tabbing wires on it. 
2. Apply flux on the back side along the white lines(electrodes), and then solder the tabbing wires on it. (The wire points above are the solder points to which you'll need to attach tabs from another cell).
3. the negative wires coming from the front of string 1 will be connected to the positive wires thicker wire called the bus. 

Soldering 
4. Attach double-side tapes on the front side if the PCB board. 
5. Lay up solar cells okn the PCB board, (36pcs in series would give about 18 volts which would be good for charging 12 volt batteries. Here just for demonstrate the point). 
6. USB connector or J-box attached on the back side of PCB board. 
7. solder bus wire on the back side by soldering wires after punching from the front side. 
8. solder bus wire on the front side
9. Heating A & B glue with a ratio 3 to 1 for 3 hours in oven or air drying it with aound 6 hours. 

Budding & Encapsulate 
10. Finished produce after heating or air-drying. 
11. voltage testing with 6.7V
12. Current testing with 2.1A 
13. Mobile phone on charging normally.
