They're not stylish, and it appears to me there's so much re-engineering to your existing home wiring to get emergency systems to work, etc. It would make sense if I had a cabin out by the lake and wanted power. But just to try and minimize electrical bills and having to wait until I die to break even doesn't make me WANT this kind of a system. The tree huggers will love you, but to only save a few bucks a month and have to be tethered to minimum fees? I'd buy more panels/batteries, and toss the electric company altogether. The lithium batteries should last you 10 years.
