ATTACHING LEADS TO SOLDER SOLAR CELLS,CLICK ON CATEGORIES FOR MY STORE
Instructions Things You’ll Need: * Multiple solar cells * Ribbon wire * Wire cutter/stripper * Soldering iron,15-25 watt and solder * Pencil eraser * Ribbon wire or solar cell tin wire * Step 1: Locate the wide line, or bus, running down the face of each cell. On whole solar cells there are multiple buses, but on broken cells there may be only one. * Step 2: Clean the bus of each cell with a pencil eraser so the solder will stick. * Step 3: Cut 10-inch lengths of ribbon wire, one per cell. * Step 4: Lay a line of solder down the length of the cell's bus. * Step 5: Place a length of ribbon wire on the solder. Leave a generous tab hanging off the cell and heat the wire with the soldering iron. The solder you just applied to the bus will melt and connect the wire to the cell. * Step 6: Repeat Steps 4 and 5 for each cell or cell fragment. * Step 7: Turn the cells face-down and arrange them in a column with the ribbon wire tabs hanging off the front and each cell laying on the back of the panel directly above it. Keep about 1/4-inch distance between the cells. * Step 8: Solder each cell's free wire tab that is on the back of the cell above it to where it touches the back of that cell. * Step 9: Repeat Step 8 until all of the cells are connected. Tips & Warnings * On both poly- and mono-crystalline solar cells, the back of the cell is the positive side and the front of the cell is the negative side. David www.solarcells101.com
