Is their an actual positive and neg on a single solar panel

Put voltmeter on DC and make sure red and black wires are in the proper contacts on the meter: black goes to ''com'' or whatever it is called. Measure your panel: if the value displayed is negative, the black wire of the meter is on the positive pole of the panel, if the value is positive the red wire is on the positive pole of the panel.

Intro Lab

When you reverse shaft rotation, you change the polarity of the voltage created by the generator. The voltmeter indicates polarity by direction of needle direction (analog) or sign of numerical indication (digital). When the red test lead is positive (+) and the black test lead negative (-), the meter will register voltage in the normal direction.

21.1: Magnetism and Magnetic Fields

Like poles repel and unlike polls attract (in analogy to positive and negative charges in electrostatics). North and south poles always exist in pairs (there are no magnetic monopoles in nature), so if one were to split a permanent magnet in half, two smaller magnets would be created, each with a north pole and south pole.
