To sum it up, Low Short circuit current can either happen if your solar panel is not getting sunlight properly or something is broken with the panel like diodes or loose mc4 connector. Always make sure your panel is getting proper sunlight and the components of the panel are in good condition.
What Happens If You Short Circuit A Solar Panel? A short circuit in a solar panel can occur by accident or deliberately. The deliberate shorting of a solar panel is to determine the short circuit current of a solar panel or simply if it is working. This is a standard procedure of solar system design and it does not affect the solar panel.

Yes, you can short a solar panel, but you likely won''t cause damage to the panel in this way. A solar panel is rated by its short circuit current and was likely shorted during testing. If your panel was damaged after you shorted it, it likely means that the panel itself was defective in some way.
Short-Circuit Current (Isc) Short-circuit current is the current that flows out of the panel when the positive and negative leads are shorted together. The current can be measured by passing the current through a multimeter configured to measure amps (this does not harm the panel, but care must be taken to avoid arcing).
The behavior of an illuminated solar cell can be characterized by an I-V curve. 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.
Types of Short Circuits. The two types of electrical short circuits are: 1. Normal Short Circuit. The normal short circuit occurs when a hot wire carrying current hits a neutral wire. As a result, the resistance will decrease immediately, and a significant amount of current will flow in a different direction. 2. Ground Fault Short Circuit
