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.

The increasing need for high capacity batteries in plug-in hybrids and all-electric vehicles gives rise to the question of whether these batteries should be equipped with a few large capacity cells or rather many low capacity cells in parallel. This article demonstrates the possible benefits of smaller cells connected in parallel because of discharge effects.
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.
