Running 24v and 12v Solar in parallel???
Just curious what would happen if one was to run two systems, side by side (i.e; in parallel)... 12v/pwm and 24v/mppt? In particular, how would the two charge controllers handle things? Would t...

Everything I've read about controllers seems to state not to mix panels with different electrical characteristics as the controller will oscillate between them trying to pick the MPP. That is for panels connected in parallel.
For a series connection, the advice may be moot as the controller sees only one voltage and current.
For the OP's situation, it may be more economically efficient to sell the 12 V system and add a third 24V module. That removes a bit of complexity. If jrnyman is using some modules as portable (trying to beat the shade), then the addition of modules makes a lot of sense.
