I am of course aware of such systems. We use solar trickle chargers on
sailboats all the time. They fill an important niche, and are fine if
you're willing and able to charge the battery for relatively long
daytime in order to get relatively short runtime.

I was talking indefinite power during the day, with enough reserve to
charge the battery for use during the night. For that you need a very
big and very expensive RV-type system.
