Don and Don are more qualifued than I am to answer this, and they
already have, but I wanted to point out another option.  With the KBT2,
the 10W panel may be too big, and you can use a 5W solar panel and the
KBT2 without a charge controller *if* the K2 is on and the current draw
is about the same as the panel output.  For example, the Northern Tool
flexible folding panel for $40 puts out 340ma at noon, and my K2 with
all options (DSP) on, pulls 320ma.  I monitor the battery voltage and
plug in the panel directly to the extra battery connection Don
mentioned.  When the K2 is off or if I want to charge the battery and
turn off options, I use Don's controller inline.

Result: after my FD operation 1B2B/WNY (we were driving to Canada from
Syracuse) I found my KBT2 fully charged.
