24 V Solar Panel(s)
Rich Solar makes a 200 watt 24 volt solar panel. I would remove my rear mounted 170 watt 12 v panel and purchase two of these Rich Solar 200 watt panels, with room to add a third if needed. One wo...

Not clear, but the OP must know he can't put the 12v 170 in with the 24v panels. I think he wants to keep the 170 with PWM and get a 24v set with an MPPT and use both controllers in parallel on the battery bank.
That's what we do in the C. Two controllers, one PWM and one MPPT. Just set the Vabs at the same voltage in each controller so they add their amps.
I would pull another set of wires to our dinette where the controllers live to the original factory installed GoPower PWM controller for the 12v 170 watt panel.
I also have a 100 watt portable that is controlled by a Victron 100/20 controller. So I would have three different panel types run by three separate controllers. As you know, it works.
The first thing I would do is install one 12v 200 watt panel and hook it to the Victron 100/30 controller, leaving the 170 watt panel on the roof. Then a month or so later, pull wires for the 12v 170 watt panel and reinstall the GoPower controller.
I have more room for controllers than extra real estate on the roof for panels.
Down the road I would install the second 24v 200 watt panel and parallel with the other 24v panel to the controller. And yes, I will buy two 24v 200 watt panels at the same time.
Enjoy,
