    How to Build a Solar Panel
    00:00:32 Part 1 Assembling the Pieces
    00:00:39 1 – Purchase the cells
    00:01:13 2 – Measure and cut a board
    00:01:47 3 – Measure and cut all of your tabbing wire
    00:02:28 4 – Use the flux pen on each of the three squares (or strip) of each line (usually 2 or 3 lines) on the back of the cell
    00:02:44 5 – Melt a thin coat of solder on the squares/strips of the back of cells
    00:03:09 6 – Heat the first half of a tabbing wire on top of the soldered squares/strip to bond it to the cell
    00:03:27 Part 2 Connecting the Cells
    00:03:34 1 – Glue the cells to the board
    00:04:31 2 – Solder the cells together
    00:05:03 3 – Connect the first row using bus wire
    00:05:39 4 – Connect the second row
    00:06:15 5 – Continue connecting the rows
    00:06:34 Part 3 Building Your Panel Box
    00:06:41 1 – Measure your cell panel
    00:07:19 2 – Cut the flat back
    00:07:42 3 – Form the sides
    00:08:09 4 – Attach the sides
    00:08:35 5 – Paint the box
    00:09:06 6 – Attach the solar panel
    00:09:26 Part 4 Wiring Your Panel
    00:09:33 1 – Connect the final bus wire to a diode
    00:10:13 2 – Connect the wires
    00:10:36 3 – Connect your panel to a charge controller
    00:11:16 4 – Connect the charge controller to your batteries
    00:11:38 5 – Use the batteries
    00:12:01 Part 5 Sealing the Box
    00:12:08 1 – Get a piece of plexiglass
    00:12:40 2 – Attach block stops for the glass
    00:13:11 3 – Insert your plexiglass
    00:13:32 4 – Seal the box
    00:13:57 Part 6 Mounting Your Panels
