The power wall smells more like an experiment and buzz creator. People act like they're serious about these power wall batteries but the fact is that they can't even produce enough batteries for the cars, so clearly the house batteries are lower priority product.
A lot of companies are coming out with similar solutions but I do think that in phase appears to have the most viable one. They are designed for upgradability and expandability, yes the chemistry is little expensive now but that will be dropping over the next few years which makes them both drop-in and easy replacement. In my case I'm going to buy one or two batteries at the end of the year when they release in the United States, then as the price drops in the future I can easily add batteries to my existing two and/or drop in replace the original batteries.

Like lots of things, early adoptors will pay a premium and be beta test subjects at the same time. Noblesse oblige for a few maybe. For the rest of the must have crowd, it may be a case of more money and ego than brains or common sense.
Reliability, practicality and cost effectiveness for electrical energy storage seem some years away at this time. I wish it was all of those things now, but wishing don't make it so.
The perception by the great unwashed masses that it is a reality will hasten the time when it does become a reality.
Manipulating and shaping that perception is the stuff of marketing and advertising hype, most of which is B.S., done not to provide accurate information, but to stir up interest, cloud the issues and ultimately make it easier to sell stuff. Seems to me that's what most of the hype on the subject I'm currently seeing is mostly about.Comment

Originally posted by Engineer View PostReliability and practicality is here I believe, it's just a matter of costs. I think personal storage is at the point Solar was some years ago, we had good enough technology but it was just too expensive.Comment

The upshot is that being 1% of the way there on an exponential trend is only 7 doublings from 100%, which we're clearly seeing in PV deployment right now. Batteries are not far behind in my estimation.

My installer offered to put it in for free so they can figure out how much to charge for installing the systems and learn the ropes, so I figure a few batteries are worth it to get the infrastructure in place gratis. As long as the battery price is say no more than $800 USD, which is the number I've heard.Comment

Originally posted by jflorey2 View PostAgreed. Especially since consumer sales are starting. There's a huge gap between "here's an idea we had in the lab" and "here's the device for sale, with UL approval, manuals and a warranty." Now we've crossed that gap. The gap from there to "here's a similar device for sale, but it's cheaper and works a bit better" is much smaller. (And I am perfectly happy to let other people keep the demand up until we cross that next gap.)
While I too have seen, read and been told the breakthrough is just around the corner, I have a good feeling that a better battery design is close to reality.

I've mused about installing a PowerWall (or something similar) but given my poco rates have dropped to only 5.6 cents per kWh, doing so is financial insanity.oilerlord's 9.23kW PlantComment
