When vandals stole my 100 Amp panel in my modular office trailer they
cut the romex off flush with the panel. To run new romex would be very
difficult. I would like to install a new larger panel and make splices
inside the new panel. I would mechanically connect and then solder
them. Would this meet the NEC or do I need to install a junction box
(gutter) to make the splices in?
As long as the splices are inside the panel, no problem, just use wire
nuts the way you would in a junction box and you should be okay.
double check that the wire insulation wasn't damaged farther up, if
they were hacking at it.
Sure, it's fine, as long as the new panel is large enough that all of the
branch circuit cables reach far enough inside it to enable you to make a
proper splice. If all of the cables came in to the old panel at one end, you
won't have much of a problem with that -- but if they came in from both sides,
say, you may have a tough time finding a new panel that's wide enough for the
cables to come in far enough on each side to give you a good splice.
Solder isn't necessary, by the way. Doesn't hurt, but you don't need it.

You usually find the crimping tool from the same company that makes
the splicing device. They are pricy but usually the only way the
splice will meet the listing.
BTW splices have a "wire count" of zero so I am not sure how they
could affect "fill". The only issue with wires in panelboard
enclosures is if they are not going to the devices in the enclosure.
I do agree with the othere poster who said a gutter or other type of
junction box at the point where a useable amount of existing cable is
available would make a cleaner install.
There are some nice "euro" style barrier strips listed for 12 or 10 ga
wire at 30a or less that will make this J box very clean.
