Hmm, we run florescent lights in camp. No inverter, they're 12v compatible, we use a socket adapter with alligator clips. One 12v deep cell marine battery charged off a $70 cheapo 13w briefcase panel runs the camp lights well enough, although we do have a 45w set available ($250 or so, on sale). We've just never used the larger panels. Always bring them, haven't needed them Have another battery on the bike for lights, two small blacklights and a rope or two, plus the running lights and head/tail lights, the charge on that one lasts nearly all week. True, we don't run the bike lights for eight continuous hours, and we do throw it on the solar charger now and again.
We haven't tried our larger blacklight like that one, but I say go for the battery set up anyway. Can't hurt to try the battery/solar combo if not interested in a genny. The stuff will still be useful. We can't run a generator unless we quit camping in Hushville. Fooling with solar is well worth it to us.
And yes, I know Ohm's law, and yes, the math doesn't seem to add up. But the set up we have is working. You tell the electrons they're being unreasonable law-breakers!
I'm too jaded to think up a good sig-line. Need more coffee.
