There is nothing particularly new about the concept. What is new is producing it as a standard module that is designed to fit into most homes with minimum effort. Producing a standard module enables this to be mass produced, rather than every installation being a custom design, so that both the system and installation costs should be reduced.
As suggested, it is specifically aimed at houses which already have solar PV collectors, and is primarily intended to extend your use of solar power collected during the day into the evening peak. This both avoids paying peak power rates, and reduces both the peak network consumption and peak feedin during the day when nobody is home, thus reducing the demands on the network resulting from both of these peaks.

Curious as to what it costs? Would be guessing $10k?
For me (and others with solar) I would run an Sp pro with a 48v 700ah system. This would cost me $16k materials only for a 33kwh system, vs ??? For 10kwh system.
Can see its benefits as a Retro fit easy all in one system though.
But by the time these are out, lithium will be old news and we will be onto molten salt batteries which from what I've been told can be drained 100%

The difference between your system and the Tesla system (apart from the bulkiness) is in the production figures. Your system may be installed in dozens of homes a year, the Tesla system hopes to be sold as a mass production unit in the tens to hundreds of thousands. Other manufacturers can and will move to produce similar batteries and drive the cost down to make them a consumer product as common as a refrigerator. Tesla intends to be riding the crest of the wave to introduce batteries into every home and vehicle wherever possible. House storage of electricity will become as cheap as hot water storage given a bit of a push by Tesla and other companies.Originally Posted by Vern

SubscriberAs I already have a 20kW solar panel installation on my roof, I have been waiting for a similar solution as the Tesla Powerwall for quite a while. I have previously considered a home-made installation, but you won't get anywhere near the Tesla product in neither price nor performance (let alone the design...).
I trust the price tag will come down a bit too, after Tesla's Gigafactory has started production. For Tesla, it will be a good way to sell off spare batteries they don't need for their vehicles immediately. For the customer it gives a bit of independence at a fair price. An ingenious win-win situation.
I have to disclose that I already own a Tesla (yep, after over 20 years of driving exclusively Solihull products I have recently added a Model S to my fleet) and am more than convinced about Tesla's capability now. If the Powerwall is of a standard similar to the vehicle, then you cannot go wrong. The only pity, you can only get the Powerwall in the US just now. I probably will wait a couple of years or so, then it will be available here as well and the price might have been halved by then.

Just found this home grown system. haven't looked fully into it but looks like it does everything the Tesla does and perhaps a bit more.

Nothing wrong with being optimistic - but current estimates seem to suggest that the US$3500 translates into A$10,000 installed (shipping, import tariff, GST, Australia tax, currency conversion, cost of consumer legislation etc), or thereabouts, and I think the halving in a couple of years is a bit optimistic.
It will be sometime next year before Tesla's factory is in production, and if this product is anywhere near as successful as many expect, that still won't even come close to meeting demand - and supply/demand economic theory suggests that demand exceeding supply is unlikely to result in a price reduction, at least in the short term. And facilities to produce batteries on the scale of Tesla's new factory are not built overnight.

SubscriberApparently , Tesla has so far gained USD 4.8 billion in subsidies from the US Government.
It will be interesting to see how the company prospers once the subsidies are removed.

Like many other companies, even Tesla has received government subsidies, especially during their start-up phase. In contrast to most others, Tesla has already repaid most of it.

SubscriberWouldn't it be nice if we backed renewable energy companies here so the technology could be developed faster...
If you need to contact me please email homestarrunnerau@gmail.com - thanks - Gav.

Plenty of systems out there like this already. That's why I ask what's so special about the Tesla?
