I don't know how anyone could conclude anything about its value with no real published specs or understanding it's interoperability within a larger system. On paper, or rather - for shareholders - it sounds appealing, sure - but most shareholders aren't burdened with determining it's true usefulness.Leave a comment:

The new powerwall appears to be the new standard for solar with battery. It contains the charge controller and the DC-AC converter, and perhaps the solar inverter. It is a great price for the functionality.
My guess is that the full off grid feature set wont be available until 2018.Leave a comment:

From a stand-alone concept, does it *require* internet access during the uptimes of non-use for remote monitoring, data collection and such?
And if so, what security steps have been taken in that regard? Does the consumer provide his own router (typically a cheap unsecure piece of junk)....

I'm really glad someone else started this thread, so I can merely comment rather than start a whole new one myself.
The average house in that area uses 1,400 kWh/month according to the local utility. Which is 325 kWh a week. Tesla's new Power Wall stores 14 kWh. As the owner of an electric car (long story), I know that lithium batteries hate to be drawn down below 20% state of charge. Yep, you can do it, but do it very often and you KILL the battery life. So that 14 kWh should be called 11.5 kWh of usable capacity. To run the house for a week, we'd need 25 batteries. At $5.500 a pop, that's $137,500.
Converting electricity into heat is a very inefficient process.

Anyone have information how they are assembled. Do you have to solder them on the roof the cells together. Probably Click and play easy to install assembly. I doubt its performace would be as efficent as regular solar panel. but its has cosmetic features that would appeal to expensive home buyers market.
