MPPT controller recommendations

If you really want MPPT look at the midnight solar Kid. But in reality, a midnite solar BRAT PWM controller or any other PWM controller gives up very little on 12V panels to MPPT. Get a PWM controller and spend the difference on another panel.
years ago when panels were expensive, or today if you use 24V panels, MPPT controllers made lots of sense. Today, not near as much.
On exception is portable panels with a long run, (100ft+) then series panels with MPPT will reduce IR loss.
