Now we can start wiring the cells in series. Using the tab we soldered to the back of each cell will now be used to connect to the front of the next cell.

Line them up and melt the tabbing from the underside tab on one cell to the top of the next cell. Keep doing this and you can get as many volts as you want. Remember if you don't plan on using a charge controller you will need to install a reverse flow diode on the positive side to prevent the batteries from draining during the night. You can get them at radioshack, or ebay or where ever you choose.

Thats basically all there is to it. Then all you have to do is make an enclosure of your liking, seal it all up and you have yourself a solar panel. I used a piece of painted plywood some pine peices for a frame and a piece of plexyglass all sealed together with silicone.
