You can wire 12 nominal panels in series to provide 24V. Typical max voltage is around 17V on a 12V panel so you would be dealing with 35V or so in a series hookup.
If you are concerned about the Outback interfering with SSB
you might also consIider the BUE Sky SB3024 as a 24V controller.
In addition to the Kyocera's, the BP panels also are rated well. Note that STC ratings are often above what you may experience in the real world as the test conditions are structured for optimum output. With an MPPT
controller, I would at MOST expect 1/3 the rated wattage to be delievered in amphours to your batteries on an average day. Probably slightly less.
The state of California
rates most solar panels under a tougher set of standards for output and you may review those outputs here as a way of comparing various modules in the real world.
