Per 690.41 you probably wouldn't need to ground it for a system like
this, but I like the idea of dropping a ground rod down into the water.
Then curve the end and find a big worm, of course.

690.41 System Grounding. For a photovoltaic power source, one conductor
of a 2-wire system with a photovoltaic system voltage over 50 volts and
the reference (center tap) conductor of a bipolar system shall be
solidly grounded or shall use other methods that accomplish equivalent
system protection in accordance with 250.4(A) and that utilize equipment
listed and identified for the use.

That is an amusing concept, and it sounds like a fun project. Why not
poke a hole in the ice and drop the rod in the water? If the water is
not too deep, send it to the bottom. It certainly will be below the
permanent moisture level!

Sounds like a silly question but is there any way to ground a small
battery based PV system serving a temporary fishing shack on the
middle of a frozen lake? Around here they call these 8' x 8' (or
larger) shacks "ice houses". One or more holes are augered through the
ice for fishing lines. Some of the shacks get remarkably fancy, almost
luxurious (in a guy kind of way). There is usually plenty of beer and
snacks. Sometimes fish, too. The shacks get set in place as soon as
the ice is solid (4-6" thick) and they may stay there for several
months. It's a home away from home for a lot of upper midwest folks in
the winter. Some like the idea of a small solar powered battery system
for light, CD player, TV, etc. There's no earth around for hundreds of
yards, even miles.
