[RE-wrenches] Grounding system for a shack on a frozen lake?

[Aladdin Solar]

The main "Official" you'd ever meet is checking for fishing licenses, etc. Yes, it would only be a small 12V system, usually DC devices but my thinking was just that if a simple grounding method would make the inhabitants safer it would be worth considering -- users don't always exhibit great judgement after many hours and beers in an enclosed space!

Dropping "non-fishing" (i.e. grounding) lines in the hole would end up snagging or tangling with active fishing lines -- especially when you get one on the line.

Would an ice or water grounding connection have any effect at all?

  There are many RVs out there too, and they don't sink a ground rod every 
  time they park.
  Use a GFCI outlet, and I think you'll be at the same safety level as 
  other portable systems.
  (Is there an ice structure building inspector?)
  You could still heat up a copper rod with a torch and then drive it into 
  the ice just to say you did.
  Post some pics this winter when its in.
  (P.S. optimum array angle will probably be as much as 80 deg due to the 
  ice reflection, and peak power could be over 125% of nameplate, use an 
  amp meter to adjust tilt)
