Step 2Assembling The Solar Cells
Next, while my first coat was drying, I started to work on assembling the solar cells. The best way to learn how to assemble the solar cells would be to simply watch the video. A quick overview of it is, the bottom of the solar cell is the positive side, and the top of solar cell is the negative side. I wanted to connect the solar cells in series, with a total of 36 solar cells, which will give me 63 watts. I used tabbing wire with a soldering iron to connect the solar cells together. For my panel I had 3 strings of solar cells. To connect those strings of solar cells, I used what is called a bus wire. The bus wire goes at the end of the strings to create one long string, however, curled up in a way like a snake. Again, for step 2, I recommend you watch the full video (Part 3) to understand how to work with the solar cells and how to check the voltage/current.

The flux is used to help bond /solderhe tabbing wire to the solar cell. Again, it's just used to "help", so it is possible for you to solder the tabbing wire without it, but I really would not recommend it.
