This should be mandatory on all new construction along with the storage system.

Amazing! Tesla will one day change the death course we are headed for! Some say the global warming is irreversible but at that rate Tesla might save us!

Hmm not exactly sure what is the revolution - solar tiles have been available for years - perhaps it is the ability to mimic all types or he has done something to improve the efficiency - but the story in it self is not exactly describing what is the ground breaking feature

Even his Powerwall batteries....there are comparable cheaper alternatives to it. I guess Tesla advertises more than others...

How do they cope with air pollution slowly accumulating on them over time, and moss growing in damp climates? Savings on energy bills might be offset by maintenance costs.

It would interesting for those of living along the Gulf coast to have some information about the wind rating of these solar roofs...

I live in an area that gets hail. My roof (and several of my neighbors) was replaced a few years ago, so I wonder how it will hold up to Mother Nature. Yes, the shingle did not shatter like others shown, but does it crack? And if it cracks, what happens to its functionality?
It would have to be cleaned of dust and water spots to keep functioning at its best. I doubt anything would grow up there, but some well-placed copper would keep that to a minimum.

This is not new: Dow Chemical had this years ago and killed the business last August. The problem seems to be that costs are higher and efficiency lower than traditional PV systems. People who want to spend the money on PV are motivated by economics, not aesthetics. I hope it that Solar City can make it happen, but it's unlikely that they can succeed where others have failed.

Looks good, but would be useless if the sun doesn't shine. 'Nuclear Winter', volcanoes, increases in space dust, chemtrails, etc.

We own a traditional 7.2Kw solar panel system that handles all of our electricity needs (we currently have built up a $500 credit with the utility and have not paid an electric bill since we installed the system in Sept. 2011.) It's difficult to say how good this roof tile tech really is without seeing the efficiency specs. For example, thin film tech has been around for a long time and has not overtaken traditional solar panels due to their inefficiency. Maybe this particular tech is better, but we have not gotten any details so far. One thing is for sure; you can cover a lot more real estate on a roof with something like this (i.e., pretty much every square inch.) Can't usually do that with traditional panels.
