Which solar panel line is positive or negative
Since electrons in a DC system travel from negative to positive, they connected the negative lead to the starter with the least amount of wire possible, then grounded the battery on the positive lead. It worked but it was a puny system. I converted it to a 12V system, but I kept the positive ground system. I did not see much corrosion though. - Download [PDF]

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.

The positive lead is on the negative terminal and the negative lead is on the positive. If the voltage is a positive number, then the polarities are correct. Either of the results tells you the polarities of the terminals.
What do solid/striped lines on a wire indicate?
Usually* the wire with the white stripe or the dashed lines carries the "positive" (+) end, while the other, unmarked wire carries the "negative" (-) end. It doesn''t matter if it is striped or dashed, the presence of any kind of marker is the indicator of the wire being the "positive" end of things, as opposed to the unmarked "negative" wire.
What is the purpose and difference between Positive and Negative Ground ...
SunPower used to make only positive ground solar panels. Due to very technical reasons, they were more efficient. They needed a positive ground charge controller to use them. They make negative grounded panels now, I can''t think of any reason to use a positive grounded controller these days. Reactions: RickP and newbostonconst. Z. Zil Solar …

The positive terminal of a solar panel is usually marked with a plus sign, while the negative terminal is marked with a minus sign. These markings may be located on the back of the panel or on the wiring diagram. If …
How to Test Solar Panels: Output, Amps & Watts
It is indicated by a solid line above a dotted line next to the letter V. 3. Take your solar panel outside and place it in direct sunlight. For best results, angle it toward the sun. When you do this the sky should be completely clear and the panel should be clean. Most importantly, double check that no part of the panel is in shade. 4. Locate the positive and …
Touching panel negative and positive wires
If you look at a solar panel datasheet and compare the current at maximum power point (Imp) to the short circuit current (Isc) you will notice the short circuit current is not significantly higher than the normal operating current. Therefore there is very little potential for panel damage by simply touching the wires together. In other words ...
