I'm fusing my solar panels individually in the combiner box before they are combined. Initially, I purchased the 15a MC-4 fuse holder and the connectors. This came out to about 6-1/2" long. Too lon...

Fuse needs to be rated to handle the full voltage of the panel in full sunlight. And for safety I like to double that. So a 24 volt panel would need 48 volt rated fuses (Or at least 36) and DC rated.
The only other thing would be the "inline resistance) of the fuse (The resistance pin to pin not blown) likely too low for your meter to measure but I'm not sure how the "Solar rated" fuses compare to standard automotive/house fuses in this aspect.
And as someone else mentioned... The fuse's "Speed" Fast. slow. standard. ultra fast) That is how quickly it blows if overloaded.
