Once you have tabbed all of you cells, you need to connect them together. The front of each cell is negative and the back of the cell positive. These need to be connected like batteries in series to form a string of cells back to front. Solder the tabbing wires from the back of one cell to the front of the adjacent cell until you have completed each line. You then use the bus wire to connect the lines. The end layout should appear as if the attached diagram.
Remember when connecting the lines that they too need to be connected positive to negative so the adjacent lines should run in opposite directions. When you are done connecting your lines together, you should have one positive bus and one negative bus which will be your solar panel outputs for residential solar supplier league city tx. These are often terminated during a special solar array box or soldered directly onto wires for smaller panels.
Once your bus wires are completed, you can add the protective glass or perspex cover over your solar cells. Run a continuous bead of silicon around the perimeter of the backing board and then carefully lower the glass onto the backing board over the cells. The silicon should form endless seal round the edges of the panel and therefore the cells will now be protected.
Clamp the glass and therefore the backing board together (in this case the backing board may be a glass sheet as well) and permit the silicon to cure overnight. Do not use screw on clamps as they provide too much clamping force and may crack the glass, instead use plastic spring clamps.
Mount the terminal box on the backing board and solder your outgoing bus terminals to the terminal strip. The box are often mounted with screws on a wood backing board or are often attached with silicon also if a glass backing board is employed . Lastly attached any mounting bracket you need to the rear board and your solar array is completed.
Connect it up to a solar charge controller to charge batteries or connect it directly to your DC load. If you are powering an AC load then you will need to connect a power inverter, read this guide on selecting a power inverter.

Cut the tabbing wire to slightly (1cm / 1/2″) over the length of 1 cell for the highest tabs and double the length of each cell for the interconnecting tabs. Now begin soldering the tabbing wire to the photovoltaic cell , see the attached video. First draw a line with the flux pen down the length of the silver tab lines. Line the tabbing wire over the tab lines and then run the hot soldering iron down the length of the tab. Do not leave the soldering iron in one area for too long as it will overheat and damage the cell. There is no need to add solder to the wire as tabbing wire comes pre-soldered.
