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.

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. 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. Disconnect all wires and let the water drain out of the panel. Turn on the voltage meter and set it to measure direct current voltage dc.

Turn off any pump connected to the solar panel. Let the panel dry completely before you start to repair the leaks. By cutting off the sunlight.
