Solar Panel Isolation / Short Protection

[JameZZ]

In a typical solar panel installation, where would you expect find the first instance of short circuit protection for the panel?

Is there normally something on the panels themselves or would the first point be at/near the inverter?

Does it need it? Isolator yes, but not sure if they need short circuit protection?

I believe some setups have fuses for the individual panels to protect against catastrophic failure of the panels themselves.

AIUI overload or short circuit protection for the DC feed wiring from panels to inverter is pointless because the short circuit current is barely more than the normal operating current.

Interesting, so if you were to short out the live/neutral directly from a panel nothing too exciting would happen?

I know very little about solar installations, or what voltage/current they produce typically.

Not sure if it makes a difference but I'm talking about one that might be installed on a commercial building.
