Leaving solar panels disconnected.
There is not a problem.
Turn off any pump connected to the solar panel.
Leaving solar panels disconnected for 6 months.
Touch the metal part of the red.
Locate any water leaks in the pipes of the solar panel.
Let the panel dry completely before you start to repair the leaks.
It doesn t matter if panels have leads disconnected as the voc will be present at the shielded tips but no current can flow absolutely nothing happens.
Excellent question and i cannot for certain tell you the answer except to say that i leave solar panels out in the sun regularly not connected to anything and they have not developed any damage.
How to safely disconnect solar panels step 1.

You don t need to disconnect that charger prior to starting your vehicle.
Older sunpower panels require a ground on the positive side to prevent polarization of the silicon cells but this rarely if ever happens on a boat.
The solar cell you have installed provides about 1 3rd of an amp charging rate.

Disconnect all wires and let the water drain out of the panel.
