Write an article based on this "Glue the cells to the board. Solder the cells together. Connect the first row using bus wire. Connect the second row. Continue connecting the rest of the rows."
Put a small amount of glue at the back-center of the cells and then press them into place on the board. The tabbing wire should run in a single, straight line through each row. Make sure the ends of the tabbing wire are coming up between the cells and are free to move, with just the two pieces sticking up between each cell.  Keep in mind that one row will have to run in the direction opposite to the one next to it, so that the tabbing wire sticks out at the end of one row and on the opposite side of the next. You should plan to put the cells in long rows, with a fewer number of rows. For example, three rows each consisting of 12 cells placed long side to long side. Remember to leave an extra inch (2.5 cm) at both ends of the board. Apply flux to the length of the two thick lines (contact pads) on each cell. Then, take the free sections of tabbing wire and solder them to the entire length of the pads. The tabbing wire connected to the back of one cell should connect to the front of the next cell in every case. At the beginning of the first row, solder tabbing wire to the front of the first cell. The tabbing wire should be about an inch (2.5 cm) longer than needed to cover the lines, and should extend towards the extra gap on the board. Solder those two wires together with a piece of bus wire that’s the same size as the distance between the thick lines of the cell. Connect the end of the first row to the beginning of the second with a long piece of bus wire that extends between the wire at the edge of the panel and the wire that’s the furthest away in the next row. You will need to prepare the first cell of the second row with extra tabbing wire, as you did with the first. Connect all four wires to this bus wire. Continue connecting the rows with the long bus wires until you reach the end, where you will connect it with a short bus wire again.
