Comparably higher voltage is more preferable when given choice between different voltages. One advantage is the lower cross-section of copper wire and assuming you are a DIYer you would want to save on that, the otherwise second advantage is that low power is lost on the lines at high voltages and currents and it matters a lot in high power systems.
What happens when you connect higher voltage panel(s) to a non-MPPT charge controller? If you connect a 24V solar panel (where maximum voltage can be as high as up to 36V), the non-MPPT (also known as ''standard'') charge controller brings the solar generated voltage down to the 12V battery charging voltage, which is 13.5-14.5V.
