Powerwall is a home battery that charges using electricity generated from solar panels, or when utility rates are low, and powers your home in the evening. It also fortifies your home against power outages by providing a backup electricity supply. Automated, compact and simple to install, Powerwall offers independence from the utility grid and the security of an emergency backup...
...Powerwall comes in 10 kWh weekly cycle and 7 kWh daily cycle models. Both are guaranteed for ten years and are sufficient to power most homes during peak evening hours. Multiple batteries can be installed together for homes with greater energy needs.
If you don't mind buying new ones every 8 - 10 years.Pretty damned cool:

It's a start but the economics do not necessarily make sense.

Will Tesla s home battery really transform our energy infrastructure Environment The Guardian
Material in blue below quoted/extracted from the article for those unable to use links:
Tesla’s Powerwall represents a further improvement, said Dr Jonathan Radcliffe an energy storage expert at Birmingham University, but for anyone watching their bills, the technology remains economically unsupportable.
........he said the reality for consumers trying to balance bills was that the Tesla battery was still not worth the up front cost. “The battery they promote for daily cycling is 7kWh. Electricity costs in the UK are about 15p per kWh, so you’re holding about £1 of value in this £2,000 wallet.”
Radcliffe said the cost to charge the battery would be around around 8p per kWh. This is the cost of off-peak grid power or solar power (once you count the original costs of solar panels). This reduced the value of the energy held in the unit to 49p, meaning the owner would need to fully drain the battery 4,000 times to recoup their outlay. Even with this unlikely energy use scenario the Powerwall would take 11 years to pay for itself, he thinks.
“I think the costs are probably still too high to make it a realistic investment, a financially viable investment. I guess the first people they are looking at to buy it are the early adopters who aren’t too worried about the actual costs but want to have this latest bit of technology,” said Radcliffe.
OK. That is what you are sure of. Here is what I am sure of. I expect to see the time when a home energy system costs less than a small car. Even at present, the prices for solar have come down far enough that a system including two of Tesla's batteries plus ten Kw of solar would be under 20K.In time the whole concept of home generation (solar/wind/cats in squirrel cages), coupled with inexpensive, long-lasting batteries, will be economical though I question whether that might ever apply to high-density apartment buildings.
The kind of government housing provided free or on the cheap to those who prefer to take rather than to make.
I'm very sure of that. But I'm also equally sure that, except for pre-teens like Jammie-Jake, most who participate on this site will have been dead for a long, long time.
But eventually.....no doubt!

Before this year is out, I will be 72. That is the extent of our disagreement. Guess we will see who is correct.OK. That is what you are sure of. Here is what I am sure of.

Oh, I DO agree with you on much of that provided the pyromaniac propensities of the little jewels can be tamed - and they likely will - one day.
Howsumever we disagree on timing.
But perhaps you are a pre-teen and the breakthru will come in your lifetime. Given the normal span of years, I do not expect to witness it myself. Probably none of my children, either.

I think that the PV's are the way to go. And we don't need to pave the desert with them, simply glue thin film to existing commercial and industrial building roofs. By doing that, virutually no transmission losses.
What can I say? I think forward, they think backward.
There are some bad examples! What do you think about?
"Powerwall is a home battery that charges using electricity generated from solar panels...."
But how do you get electricity?
It is a bad example (in my opinion) : The Ivanpah Solar Electric Generating System, Google-backed 2.2-B US solar thermal plant opens as industry grows Manila Bulletin Latest Breaking News News Philippines
It is energy Saving and cheap?

Bird deaths at Calif. power plant a PR nightmare for industry
Phil Taylor, E&E reporter
Greenwire: Monday, January 19, 2015
Impacts on other projects SOLAR Bird deaths at Calif. power plant a PR nightmare for industry -- Monday January 19 2015 -- www.eenews.net
Ivanpah officials say the plant's impacts pale in comparison to larger human threats.
They include building collisions that kill an estimated 365 million to 988 million birds annually in the U.S., according to a 2014 study by federal scientists in the journal The Condor: Ornithological Applications"
