(2) 12V Solar Panels....Series or Parallel?
I have (2) 140w 12V panels. The Bogart Engineering solar controller can operate on 12V or 24V input. Is there any advantage or disadvantage to wiring the panels in series for 24V rather than parallel ...

So do I, but a quick wire swap makes it 24v :) Then you need to find some 12v as stated earlier.
Yes. There are (relatively) inexpensive DC-DC converters to run 12V loads off 24V bank. But this complicates things, more parts to fail. And you are right that non-solar charging and inverters also need to be 24V-compatible.
What SMK said - if they go to 500W, then they could consider 24V. Makes sense lowering the amps then. As it is now, with their current setup - this is just a geeky stuff, toying around.
