the cool thing is that they look good... they look like a normal roof at the angle you would see from the street in front of the house, but from above... from the angle of the sun they are transparent and you can see the solar cells. I know some rich people that want solar but their neighborhood associations won't allow it, but I don't think they would not have an objection to these roofs. they look really nice.... I…

In CA, it is illegal for HOA to block solar installations

Also in Florida, surprisingly.

I have no particular desire to sign up just to watch the video, but I hope that the Powerwall 2 is compelling enough to beat out the LG Chem RESU. For reference, the RESU is a wall-mounted Li-ion battery meant to be connected to a solar inverter. It seems to beat the Powerwall in basically every respect. It's a bit cheaper, it has a better warranty, and it has slightly lower advertised capacity but higher warranted c…

Tesla version integrates the inverter and has double the capacity(14kwh) for the same cost as LG Chem REsu 9kwh version

One 14 kWh Powerwall battery $5,500 Installation and supporting hardware starts at $1,000

Solar panel roofing tiles have been around for a long time. I wonder what this will do different? Pricing? Or perhaps they are relying on brand strength alone. Edit: I understand the urge to downvote because I'm not singing praise, but I promise I'm not trying to be overly pessimistic or critical of what Tesla is doing. Fact of the matter is, solar tiles have been done before, and failed miserably.

The price of PVs has fallen by multiple orders of magnitude in the past half century or so[0]. This is a staggering change! [0] http://blogs-images.forbes.com/peterdiamandis/files/2014/09/...

Great comparison of solar price decline along side other fuels:

That graphic really drives the point home, but it needs to be plotted logarithmically to get a good comparison.

Nobody is going to buy this for the "cool"ness and "shiny video", they're going to buy it for the higher capacity.

It's still nearly a 65% increase, and includes the inverter. I don't see how the PW2 isn't a better deal.
