Solar battery chargers are at best, unpredictable
'trickle' chargers. Their output almost never meets
nameplate numbers. Output is subject to vagaries
of the sunshine. Output is not controlled to prevent
overcharging of the battery.
My recommendation for a battery-only electrical
system, particularly if the battery is a light
weight and relatively expensive lithium device
is to take it home between flights and put it
on a charger-maintainer recommended by the
battery's manufacturer.
I had readers doing this with SVLA batteries
25 years ago who reported excellent performance
and longevity from the battery. This was common
to both sail plane owners and owners of powered
ships with electrical needs but no engine
driven power sources.

As a data point, a friend who sells rides in a 1929 TravelAir biplane did
it for years with a battery-only starting system. He did finally have a
generating system installed for convenience, but the fact that he ran a
commercial operation with a 'total loss' system shows it can work well. I
wish I could tell you the size of the battery he used, but I can't remember
and he never knew (good pilot, but mechanic, not so much...).
