It is therefore recommended to disconnect faulty circuits in case
I shorted my Panels Are they Dead?
Shorted panels produce Isc (amps, short circuit) and if there are some thin or defective traces, they may be damaged long term, but shorting a good PV panel should not hurt it, even for an hour. 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.

Solar panel supply
Short circuit current of a solar cell is not quite like anything else. The solar panels are just long chains of photo-diodes, albeit rather large area ones, so very slow compared to rectifiers. And diode-like they have a highly non-linear current voltage characteristic, that depends on the light level.
