If you were an expert on roofs, you would have written the costs as per square, which = 100 sq ft as installed.
Thank you for the clarification as to the term used in the industry.

Cost of Tesla Solar Roof Tiles

Thank you for the clarification as to the term used in the industry.
To my way of thinking, in this application, energy density - probably not the most correct term, but usable and understandable, is the least problematic of all the challenges:
- One has to tile one's entire roof
- One is most likely to use the same...or same-looking...tiles on the entire roof
- Most roofs' surface area exposed to the sun, at even low photon capture (i.e., lower efficiency #s), will more than suffice to provide their respective houses' kW needs and their associated Powerwalls' kWh storage demands

No better insolation data available to Joe Homeowner, but it obviously does not know anything about your local shading.

Yes, far better than a general rule of thumb for PV installations.
I have shading from large trees and generate about 2/3 of the calculated KwH.
The other thing nice about the tool is, like all tools, just that. One can always discount for shading, etc. It's a great starting point with a methodology one can dig into if they like.

I've sometimes wondered if people realize that PVwatts gives insolation data upfront and then uses it to calculate PV production.
Regarding shading, the most brilliant (and actually simple once some thought is given to how the magic is performed) nifty tool I have ever seen is the solar pathfinder. People who buy it seem to agree with me because I have never been able to find a used device for sale. I'll have to give some thought to a DIY version since I really only want one for enjoyment.

Much like Tesla's cars, their roofing, solar, battery microgrids are at least at first upmarket products. Expect them to cost 5X as much as typical asphalt shingle roofing, more than $50,000 and sell for houses that cost more than $500,000.
There are about 5 million new/replacement roof sales per year and Tesla would be interested in taking a large share of the top 10% by price. Half of the the top 10% is still 250,000 a year @ $50,000+ or over $12.5B.

There are a ton of middlemen in roofing. Manufacturer, high margin sales organization, hugely overpaid sales contractors, contractors. It's a pretty f'ed up supply chain with a lot of waste. Typical roof is sold at 4x what it should be

Have you seen the SolarCity soft cost breakdowns? Not much prettier, though I certainly expect Elon to attack that first thing tomorrow.

That's pretty clearly what they are comparing. The roofing types they showed like slate and tile already cost 5X+ asphalt shingles. That's what they mean about shipping costs and breakage. Neither are about asphalt shingles...slate and tile are delicate.
He's basically confirming they won't cost MORE than slate...which wasn't implied before when they seemed to subtract the energy savings to be competitive. If they can cost no more than slate or tile, have comparable looks and life and also generate electricity they will dominate the high end of the market.

I think you're right. That will be the Roadster to Model S ramp up of Tesla Roof.
Then, later, in a few years, they will show their own internal economies of scale, sales and installation efficiencies, and start pairing lower price options with some of the lower end Model S or higher end Model 3 and PowerWall 2.X, and the costs will start to look attractive to some of the higher end Model 3 / lower end Model S buyers that have either an old roof being replaced or a new house going up.
If Tesla Roof keeps their R&D, manufacturing, sales and installation teams going healthy and strong, with good leadership and management, they will have some good competition that helps them expand the new marketplace, but will keep making enough margin themselves to help expand that new marketplace pretty strongly themselves and make income, all the while the price keeps dropping. That is what I'm hoping, anyway.
a bit more technical data on exactly how the roof goes on, electrical connections and such would be appreciated.
Is it perhaps a membrane goes down on roof, then some kind of grid the tiles go in,
how do they couple? is it inductively?
Does each tile have an inverter with MPPT built in?
how do you get the electrons collected?
