RE: DC solar panel wiring

Hi Billy.

I will try my best to explain how to wire your panels.

To wire your panels in parallel, take all of the plus terminals of each panel and connect them to the same wire.  Take this positive-voltage wire and connect it to the positive lead on your motor.  Now take all of the negative terminals and connect them to a common wire.  Take this wire and run it to the negative side of your motor.  This is a parallel wiring scheme.
Now if you reverse the wires on your motor(assuming its reversible) the motor should run backwards.


Now to wire in series,  connect a wire onto the positive terminal of Panel 1, and leave this wire unattached.  Now connect a wire to the negative  terminal on Panel 1 and connect this wire to the positive terminal on Panel 2.  Now connect a wire to the minus terminal on Panel 2 and run this wire to the positive terminal on Panel 3.  Then take the minus terminal of Panel 3 and wire it to the positive terminal on Panel 4.  Now connect a wire to the negative terminal of panel 4.  At this point, you should have one wire coming off of Panel 1's positive terminal, and one wire coming off Panel 4's negative terminal. Take these two wires and connect them to your motor.  You can reverse them too and watch your motor run backwards.

I hope this helps.
