It might represent an additional short circuit path carrying current supplied by the solar panel. With respect to the comment, prospective fault current that is very much above 1 PU would be electronically limited. Any failure of the electronic limit would essentially create another short-circuit path.
shorting solar panels for testing current
They try to hold 12 VDC or 120 VAC. You connect a volt meter just fine (very little current draw, of course the correct voltage range). And if you attempt to connect a current meter, which looks like a dead short, you get very high/unlimited current flow (pop a fuse or circuit breaker, or over heat a wire or device and start a fire).

Why is my solar panel short circuit rating much higher than in …
Solar cells are specified with two values - short circuit current (in your case 100mA), and open circuit voltage (in your case 6V). 100mA does not mean 100mAh, and the rating of the cell is definitely in mA not mAh (mAh would be completely meaningless for solar cells). You may be wondering why it is rated in terms of short-circuit current …

Understanding the Voltage – Current (I-V) Curve of a Solar Cell
Interconnecting several solar cells in series or in parallel merely to form Solar Panels increases the overall voltage and/or current but does not change the shape of the I-V curve. The I-V curve contains three significant points: Maximum Power Point, MPP (representing both Vmpp and Impp), the Open Circuit Voltage (Voc), and the Short Circuit ...
Solar panel short circuit
Solar panels are designed to be continuously operated at very very close to their short circuit current. A good quick test of a solar panel is to run it short circuited into an ammeter. While it is conceivable that a solar panel may be damaged while running under short circuit, if it is then it is faulty and would also have been damaged by ...
Solar Panel Series Vs Parallel: Wiring, Differences, And Your Right ...
When solar panels are exposed to varying amounts of sunlight due to partial shading or facing different directions, parallel wiring reduces system losses. Each solar panel operates independently, meaning one panel''s reduced output doesn''t impact the output of the others. 2- If you have mixed solar panels with similar voltage ratings:

Can Short Circuit Damage Solar Panel?
More efficient panels have a higher best operating voltage, usually about 85% of the maximum voltage. The difference between the best operating point and a short circuit in terms of energy loss is very small. This is because solar panels almost always produce the same current. There''s a diagram that usually shows how solar panels work.
I shorted my Panels ... Are they Dead?
Solar panels are CURRENT SOURCES and NOT Voltage Sources like a battery. You can short any panel out for a day, week, month, or year with no problems. In fact that is how you test a solar panel. As CURRENT SOURCE current is limited and in a solar panel is Isc. A shorted panel cannot even heat up its own wires.
