Mixing solar panel sizes
On a MH roof you have some large spaces and some smaller spaces or spaces with possible shading issues that you would want to avoid. Can you mix panels of different physical sizes / wattages, but of ...

Yes you can parallel eg, a "12v" 160w panel with a 12v 100w panel for an array of 260w. BUT you cannot mix voltages such as add a 12v 100w panel to a "24v" 255w panel.
Better not to mix mono and poly either--they act a little differently in low light. Can be done though.
You can have a 24v set of panels with its own MPPT controller and another set of 12v panels with its own PWM controller, set both controllers to the same high set point voltage 14.8v eg, put both controllers on the same battery bank, and they will add their amps.
