I'm sure i'm not the only one who feels like this is possibly the iphone moment of Solarcity/Tesla: an old-ish idea, made sexy and tasty to consumers, together with technology reaching a tipping point(and also Musk again finding a way to maximally exploit government subsidies for clean tech.) The tesla car itself could count as well, but felt less "design driven" imo. If this fails, everyone will call it obviously du…

>>SC will be able to have a monopoly on these modules and their installation for a long time to come Is that really Elon Musk wants, monopoly ?

Monopolies make money and you need money to do cool stuff

Agreed, look at Google. Monopoly on search, and has definitely built some cool stuff.

I had serious misgivings when Tesla/SolarCity announced a switch of focus to building-integrated PV. Historically, BIPV is where a PV technology goes to die after it's failed to compete against incumbent module designs. But these have far better aesthetics than previous BIPV efforts. They look better individually and they aren't clumped in one odd shiny patch on the roof like past BIPV. Search for images of solar shi…

Maybe, but one important factor is that having a patent-protected lock-in on a market that has a great deal of potential will certainly make his investors happier.

Hope it is insured against golf ball sized hail. If so people in Texas will buy this in droves just for the durability. In not it will never sell in Texas.

In the video they demonstrated the tile by dropping kettle bells on them. They've definitely thought of hail.

That's brilliant. It fixes that huge objection we all have to solar on our houses - and it is not the product itself but that it is a innovative solution to a problem "everyone" has looked at and said "nah I don't want that rubbish on my roof" and nearly turned it on its head It's just one more example of why discounting Elon might be a bad idea. If only I had bought tesla a few years ago ...

nah I don't want that rubbish on my roof I literally haven't seen my panels since the last time I went up on the roof. Granted, this depends a lot on how steep your roof is, but the appearance of the panels did really not go into our decision to install them.

But perception is reality. Both homes and cars are largely purchased on appearance.

Did you see the announcement video? They dropped a kettlebell on it and all it got was a small crack.

Now think about what will happen after water makes its way into that crack and goes through a few hundred freeze-thaw cycles.

Isn't there a significant difference between a kettle bell and golf ball sized hail?

Side topic, but I wonder if there's a pivot point coming where household appliances could be offered in DC versions. It would be great to avoid the inverter efficiency loss / point of failure. Could there be a standard DC interior wiring system with line voltage for the fridge / dishwasher / laundry machines and let's say LED lights, phone chargers, etc? The need for AC power is just an artifact of long transmission distances, right?

I'm curious if anyone has stats on what percentage of houses have an unobstructed southern roof (for those in the Northern hemisphere)? My house has seasonally adjusted nanotechnology self-replicating shade "panels" that block considerable sunlight in the spring and summer months (MTBF: 100+ years). The big downside is cleaning up the unused panels in the autumn.

For a moment I thought you were talking about these nanotech mirrors.

That has to be the geekiest explanation of a tree I've seen in awhile.
