Off-Grid Solar?

Form AND function.

I stumbled across this article on off-grid solar this weekend. It got me thinking what it would take to get my house totally on solar power.
I already use a solar-powered fence energizer for the sheep and donkey (and soon, chickens). It's one panel that trickle-charges two batteries. I love it. I plan on getting more.
But the whole house?
It's something I'm looking in to.
That 30% tax credit is calling my name, too.
It's on the radar.
