Tesla Motors Announces a New Home Battery

Re: Tesla Motors Announces a New Home Battery
#2I've always been wondering why there have never been affordable local power storage solutions on the market.
I'd love to have a battery like this to store excess power from solar panels. Returning power to the grid is a waste in both efficiency and money (you just make the power company richer).
Unless you live in Germany (where there are laws forcing power companies to buy excess energy back against peak price), a battery should be the way to go.

#3It looks like Elon wants to ramp up production in the new Gigafactory right away, and create home batteries from the excess capacity. A Gigafactory running at full capacity should bring the cost of lithium ion batteries way down. Electric cars haven't hit the mainstream yet, so he has to do something with the excess capacity, and this looks pretty straightforward.
So even if he sells these batteries at the break even point, he'll still get much closer to an economically viable Model 3, because the battery is such an expensive part in an electric car and this will bring the price of batteries down.
(I'm not sure if my reasoning makes sense though, because the Gigafactory isn't anywhere near finished yet, and according to wikipedia it won't hit full capacity until 2020.)

#4Can someone explain to me why being able to build off the electrical grid is worth all this effort since you're still going to need running water, sewage, bins collecting, broadband and a number of other things?

#5Could someone please fix the truncated title? My editorial advice would be to just cut from the semicolon.

The UK also pays domestic solar producers for feeding in to the grid - it also pays for the generation as well.

#7It will be interesting to see the market reaction to this regarding the value of electricity generation companies.
Governments that lean too heavily on taxes or state run monopolies for energy generation should also be concerned. There are places that tax generation from sources like the wind (for example, Nova Scotia), so I wouldn't be surprised if we see solar tax appear.

#8If we were able to create individual or community power grids; imagine how much infrastructure could just be removed. Maintained by the individuals owning it, instead of these stupid power companies and the way they work now.

Not sure most of those need physical connections. We can drive our garbage to the dump and also compost. We could dig a well, and we have a septic tank. We could get satellite internet. Physical connections for electricity is about the only absolute, unless you go solar, but then there's not a good storage mechanism for cloudy days (from what I can tell).

Home batteries have arguably fewer cycle times than a battery in a Tesla. By selling these, Tesla is essentially selling beta models to figure out kinks in the factory, in the batteries, etc, before putting them into their mainstream vehicles that have to suffer huge temperature gradients, lots of recharge cycles, etc.
