Step 5: Wire Up The Solar
First, we're going to wire up our solar panel.
I like to connect my 1N914 diode directly to the Positive solder tab on the solar panel. When soldering make sure the black bar on the 1N914 diode is point away from the solar cell. The black bar is the Negative side and prevents power backflow. If we put it in wrong we're going to prevent power from flowing into our circuit!
Solder the diode's Positive side (non black diode) to the Positive Solder Point on the solar cell. Solder a wire to the other end of the diode. (In the photo it's the red wire.)
Solder a wire to the Negative solder point on the solar cell. (In the picture it's the black wire.)
Then tape it up for protection.
