My experience with solar panels (while cruising) is that it does ramp up
very slowly, from zero volts to the max (which is about 16 volts).  It
also is not consistent when starting up, because a cloud moving over the
sun or the boat swinging on the mooring will change the voltage.  Once
the sun gets up good this is normally not a problem, but would be until
it gets up in the sky good.  And the same holds true of the sun going down.
