which cable is positive?
White for negative denotes this is a grounded system and the negative is grounded. Grounding the positive is also NEC compliant and would thus have a white wire carrying positive. If this is an ungrounded system (also compliant in some circumstances) then neither wire should be white. Red and black are acceptable colors to use.

8.7: Diodes, LEDs and Solar Cells
Diodes are semiconductor devices that allow current to flow in only one direction. Diodes act as rectifiers in electronic circuits, and also as efficient light emitters (in LEDs) and solar cells (in photovoltaics). The basic structure of a diode is a junction between a p-type and an n-type semiconductor, called a p-n junction.

6 FAQs about [Is the red wire of the solar cell the positive pole ]
How do I find the positive and negative terminals of a solar panel?
To use a light bulb to find the positive and negative terminals of a solar panel, follow these steps: 1. Connect one wire from the light bulb to one of the wires coming from the solar panel. 2. Connect the other wire from the light bulb to the other wire coming from the solar panel. 3. Observe which wire causes the light bulb to light up.
How do you know if a solar panel is positive or negative?
The positive and negative terminals of the panel are located at either end of this series. One of the easiest ways to identify the positive and negative terminals of a solar panel is to look for the markings on the back of the panel itself. Most panels will have a label or sticker that indicates which end is positive and which end is negative.
What does polarity mean on a solar panel?
Let's look at what the word polarity means. Polarity essentially means that the generator has positive charges on one side and negative charges on the other. The voltage difference allows electric currents to flow from one end of the wire to the other. You need a voltmeter or multimeter if you want to check the polarity of your solar panel.
How do I know if a solar panel is polar?
If you’re mixing solar panels of different wattage, you need to make sure the positive and negative diodes are lined up correctly to prevent burning out the system. You can also use a volt meter to measure the voltage. This determines the solar panel's polarity.
How do you measure a solar panel polarity?
You can also use a volt meter to measure the voltage. This determines the solar panel's polarity. Even when inside a building, a simple voltage reading will reveal the polarity of a solar panel. Put the red positive meter lead on one side and the black negative lead on the other. This measures across the terminals or wires of the solar panel.
Is a red wire a positive or negative wire?
The red wire is a phase 2 “hot” wire, which means it’s also a live or positive wire (but the black is the primary positive wire). The blue wire (if present) is a phase 3 “hot” wire. The white wire is neutral.
