Make a Solar DS "light" (Version 1)

Step 3 Attach the Diodes

A diode is an electrical component that allows electricity to flow in one direction only. In this case, it is used so that the solar panels can charge the battery but the battery can't discharge into the solar panels. On the positive end of one of the panels, solder the anode (the end without the white stripe) of one of the diodes to the positive end of one of the solar panels so that the diode points down. Solder the anode of the other diode to the other panel so that it points up. After that, use a dab of hot glue to secure the diode to the solar cell.
