I wonder - if you run current through these when they're covered with snow, will they heat up and melt it away?

Musk recently posted to Twitter about using dedicated heating elements in the tiles for this purpose: https://twitter.com/elonmusk/status/792218248917811204

Very cool! It seems like it worked for my place: "0 sq feet available for solar panels Based on 3D modeling of your roof and nearby trees"

I tried an address in Cave Creek AZ.

2000 hours of usable sunlight a year.

4664 sq ft available for panels.

Total 20 year savings: $1,000.

Seems... underwhelming.

Oh, this is for a lease.

$2,000 if you have to borrow to install the panels. Still... $100/yr?

The only worthwhile benefit is you can afford to pay $21,000 out of pocket.

In coastal regions of the PNW it is not uncommon to see moss and algae growth start within 3 years of a roof being installed. Replacement can be necessary within 10 years if the problem isn't dealt with. source - owned a roof cleaning company.

Yep. That's where I am. Currently getting a HELOC for when the inevitable happens, planning on getting a metal roof instead of this asphalt claptrap. Figure it'll cost 3x as much but last 5x as long.

Though I would presume roofs where moss and algae are a problem if not dealt with aren't great candidates for solar.

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.

Yeah people seem to disagree but I find it weird to see Silicon Valley seems to dislike monopolies but constantly builds them. Google, Amazon, Facebook, Microsoft, Intel, really just name any big tech companies and they probably have a monpoly or something very close to one on something. There's no problem with it and the only real way to get the returns that people expect is to create a monopoly somewhere.

What I find most clever about these roof panels is that is will likely silence a lot of HOA critics. While more and more states are considering "solar rights" laws, it is still better for all involved not to have to fight that battle.

I live in a historic preservation district, with a south-sloping roof. I'm not permitted to put up solar panels because they'd be visible from the street, but these have a chance of getting past the historic preservation authorities. That would be fantastic.

Thick glass tends to be fairly resilient so anything that's going to damage these would likely destroy normal tiles anyway. Depending on how modular these things are they should be able to deal with breaks without significant problem just run in parallel like the good Christmas lights which still work when one goes out.

I had a ceramic roof once. Walking on the roof would break the tiles. It made it hard to do maintenance on anything up there. My preference these days would be for a metal roof.

Corrugated iron is infamously loud in rain. What type of metal roof are you considering that wouldn't be such an earsore?

It’s not weird actually. Monopolies are bad for people who want to create monopolies.

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…

From a popular perspective - you are maybe right - they 'sexified' something not quite so sexy. However - I suggest this won't work out like the iPhone. Why? Because --> 'new roofs' are not built that often, by that I mean new homes and roofing replacements. And the construction industry has totally different dynamics. Putting on a 'regular' new roof is expensive. Most people won't consider this tech unless their hom…

> 'new roofs' are not built that often

Source? Roofs last 20-30 years. 125 million homes in the U.S., with roofs being replaced every 25 years means 5 million roofs per year. Triple that for Europe, China, and the rest and you've got 15 million a year. It's a big ticket item so you don't have to capture that much of the market to start hitting pretty serious revenue numbers.
