I thought they were "gel cells", but looking at Wikipedia, I guess
they're essentially the same, except the cell chemical is different, and
the lack of needing to add water. I don't know about the power draw
differences between the two, though.
It'll be hybrid. Eventually, I would like to go 100% off-grid, but that
might be a bit. Looking at 220W panels for roughly $500 makes it very
attractable for my wife and I.
Not only solar, but I've looked at a gas generator as well. Gas is
cheap, and the generators are inexpensive, so that could work in an
emergency for a day or two worth of power (as long as I can keep feeding
I'm in contact with someone else in Ogden who is meeting 1/4 of his
power needs with only 6 175W panels. He's planning on getting 3
additional panels. He's mentioned some unique wiring schemes with the
batteries (parallel, vs serial, vs hybrid wiring). And the tax credit
makes it worth the initial cost.

I don't know anything about selling the power back. For the time being,
I'm just concerned about minimizing my power bill. I'm sure there's all
sorts of politics involved, good and bad. I guess time will tell. But I
would imagine just paying for the line feed would be cheaper than my
monthly bill. Maybe not. I'll look into it.
