"It's not that simple. A system that is not grid connected will need a lot more than just a battery to make it as reliable as a grid connection. Those 'few short years' are more likely a couple of decades, in other words well over the horizon for the people that are currently trying to squeeze the most profit from those utilities." How are panels + battery not as reliable ? I think you mean they don't last as long, right ? As in, theoretically you could use up the battery before the sun rises again so it's not as nice as the utility ... As far as I can tell, panels + battery (properly sized, and admittedly expensive) are all you need. You can just cancel your electric service at that point.

No, it's a matter of coverage. Every year you'll have one stretch of 4 to 7 days without appreciable sun and this tends to deplete your batteries to the point where you will wreck the pack if you don't recharge. So you install either a wind generator, a genset or both. > As far as I can tell, panels + battery (properly sized, and admittedly expensive) are all you need. In some locations this may be true, in most it isn't. > You can just cancel your electric service at that point. As soon as you have backup power you can do that anyway.
