Probably not directly. but seriously maybe. The trick will be not the voltage but the amp-hours. If your doing panels for the residential, that basically nominal 220 V across the two hots.
As far as I'm concerend the concept of electric panels is fine, the catch with existing buildings comes with roof installation when going with one of those lease deals. Since they front the cost and take a cut, your now in a relationship where if there's an issue with your roof, it has to be worked out. Not good IMO.
So just get a little 12 Volt deal hooked to some car batteries - you can then pair up a couple for some emergency arc welding.
