Step 5: Soldering Bus Wire

Next, after hooking all 3 strings of solar cells up in series, I was ready to get my 22 gauge wires (red and black) ready for soldering. On the ends of my leads from my gauge wires, I connected some connectors to make the process of soldering them down to the bus wire a lot easier. Watch Part 7 of the video to see how I went about doing that.

To help give the inside of the solar panel a nicer look, I used 2 strips of wiremold and ran the wires inside those. This is also seen in Part 7 and Part 8 of the video. Afterward, I took the panel outside in the sun to test the voltage/current of the whole panel to make sure I was getting 18 volts and 3.5 amps in an open circuit and short circuit.
