It depends on what your new panel is going to be.
This Victron site is quite handy to calculate MPPT size: https://www.victronenergy.com/mppt-calculator
Bear in mind that simply adding another panel can be more complicated than you think if it is a different voltage or capacity than the existing one. Will you connect the panels in series or parallel? If parallel, is your existing cable thick enough? If your new panel is same as existing series is better as you keep the same cable and possibly upgrade your MPPT controller to a SmartSolar MPPT 100/30. The 100/30 gives you ample room for voltage (100v) which is the most important, but the amperage may be exceeded under ideal conditions (once in a blue moon) but it doesn't really matter.
