if your roof generates electricity, it can explode theoretically?

Well so can your phone but nobody worr- oh wait
They say breakage during shipment is a problem. So how do these glass panels work in the elements? And are they transparent? Could a helicopter, for example, be able to see into my attic?

not really, but the batteries that store the electricity could if they weren't over engineered to be safe if we're talking about the Tesla Powerwall

So if someone looks at my roof they see plywood? I just want to know how it would look when it's installed
Can I get one on my RV?

If a photo-voltaic panel was transparent, that'd be an awful waste. However, the cells of the panel are invisible from an angle while they are visible from the top of it.
The tiles themselves are apparently made of tempered glass.
The roofing tiles look like this: [img_thumb]https://www.tesla.com/tesla_theme/assets/img/solar/styles-textured_glass.jpg?20161025[/img_thumb][img_thumb]https://www.tesla.com/tesla_theme/assets/img/solar/styles-terracotta.jpg?20161025[/img_thumb][img_thumb]https://www.tesla.com/tesla_theme/assets/img/solar/styles-slate.jpg?20161025[/img_thumb]

[QUOTE=rampageturke 2;51389989]How secure are these roofs? Not uncommon here on tge west coast uk to get 40mph gusts which pull of roof slates[/QUOTE]
What kind of shit roofs are those ? We get winds over 150kph(100mph) here and nothing happens.

architectural standards regarding stuff like exterior finishes like roofing and facades often account for expected weather patterns in the region, so high winds at rampage's place fuck shit up while yours are a bit better nailed in, whereas his roofing may be better capable of handling constant rain/humidity/freezing over or something
though 40mph winds doing much of anything probably means the slates getting peeled up are just old and loose

Go to 8 mins and Musk shows off houses with the roofs on.
[QUOTE=Big Dumb American;51391013]Solar panels are becoming more efficient and less expensive by the day. I can't say whether Tesla's claims are actually accurate, but I can say that, assuming we have reached the threshold wherein the price of solar energy technology and the amount of energy it is capable of producing have reached a justifiable ratio for most homes, the roof is objectively the best place to put it. Every home in the country has a roof, and almost all of those roofs are generally unclaimed real estate that would otherwise serve no functions beyond simply keeping the weather out and looking good.
Solar roof tiles are a phenomenal idea. Even if they aren't 100% efficient 100% of the time, we're talking about a massive reduction in reliance on the energy grid. Solar roof panels, which would largely be purchased directly by consumers, in reliance with clean energy grid options such as windfalls (primarily paid for by the government) could be the key to one day achieving a near-total transition to clean, renewable energy.
This is a good thing.[/QUOTE]
Solar panels suffer very serious grid penetration problems because every other panel in the grid produces their power at the same time. You therefore very quickly reach a limit at which adding more panels doesn't contribute to lower energy demand.

Without enormous amounts of energy storage you simply can't take advantage of the energy generated.
[QUOTE=Morgen;51391095]Not ever panel is a pv panel. Some are dummy tiles.[/QUOTE]
That would explain a lot. But I'm still incredibly sceptical that Musk is the very first person to discover gaping inefficiencies in the roofing businesses. They would have to be huge to make up for the increased cost of solar panels.
[QUOTE=dai;51392159]you're the most pessimistic baby about this, what the hell. Why is it a waste to spend less money than a normal roof would cost to install this? New homes will be built with them because it's a no-brainer, and as buildings degrade they need maintenance and would benefit from making the switch instead of continuing to patch the old one. Even if it can only generate electricity efficiently only for a few hours of the day, or only during certain seasons (before citing the fact they can install cheap heating elements to keep snow from building up on it), it's not doing anything less than an old roof in its off hours.[/QUOTE]
And you're a naive baby to automatically believe a very tall claim that solar panels can be made cheaper than concrete tiles. If you'd actually read what I posted you'd have seen I also doubted the claim of costs.
[QUOTE=AntonioR;51392533]What kind of shit roofs are those ? We get winds over 150kph(100mph) here and nothing happens.[/QUOTE]
Well i guess the question leads more to are they long lasting, as the houses where i live and their slates are getting pretty old
[QUOTE=Bryanrocks0;51392459]They say breakage during shipment is a problem.[/QUOTE]
I believe ceramic tiles have the same problem.

I think it's okay to be skeptical of the cost but why would you discount it entirely? It's not like it's coming from some startup with no credibility. The guy saying it has a huge amount of experience with supply chains and designing things in a way to bring down costs.

Naturally, energy storage is something that goes hand in hand with solar energy generation, else solar power would be largely pointless. However, essentially every home that currently invests in solar panels also invests in energy storage for those panels, and I don't imagine that changing as we move forward. It could well be that Musk's claim that the solar roof is competitively priced with more traditional kinds of tiling did not account for the need for those storage costs, but that doesn't really change the nature of the discussion. The compaint you've raised is one that's already well addressed by existing technology, and (like solar panels themselves) the cost and efficiency of that storage is steadily improving. Solar energy may not ever reach a point where it's the singular solution to our energy problems, but it does serve to significantly decrease our overall reliance on other forms of energy generation. New technology to make solar energy generation more cost effective, more energy efficient, and more convenient (such as solar roof tiles, window films, etc) are nothing but a good thing.

Because roofing is a huge and mature industry with multiple suppliers. One of them would have seen the opportunity to undercut their suppliers and taken it if it was the case.

So, your opposition to innovation is based on the argument that nobody has done it on a large scale before, and thus it must not be viable? Have stopped to consider that the reason these roofing supply companies haven't already made a serious attempt at this is that they aren't also multibillion dollar tech giants dedicated almost entirely to the research and development of sustainable renewable energy alternatives, and thus didn't have the funding, facilities, expertise, or motivation to pursue this?

I think small improvements could be made but not at large as Musk is claiming. The gap has to be huge given he's claiming solar roofs will be cheaper than traditional roofs before the electricity generated.

Roofing companies are not concerned with energy. If your logic was sound, there would be no innovative startup companies because existing ones would've seen the opportunity. Sometimes it takes an outside perspective to see an opportunity within an industry. Kind of like Tesla, SpaceX, and SolarCity...

While his estimate of the price may or may not be overly optimistic, I think your logic regarding the potential of the technology itself is pretty flawed.
Make a solar roof that generates sunlight.
Infinite energy.
doesn't look too bad, and if it's as cheap as its been stated then its pretty much adding free value to a house.
[editline]19th November 2016[/editline]
and its a pretty fucking bold statement to say it costs less than a new roof which costs between $6,000-$15,000 at most

Costs less than the concrete or ceramic roofs, not the asphalt shingles

Steel is another common roofing material which is extremely robust and not much more than shingles.
[editline]19th November 2016[/editline]
Looking through the vids this is going to be too expensive for the vast majority in North America who use shingles. And your returns on power take longer and longer the further north you go.

That really is fine, even if there's just something like a 2% adoption rate at first it will be a success, technology improves over time and that percentage will only increase.
[QUOTE=download;51390408]Like Solar Roadways a solar roof is not going to be pointing the right direction to get the most amount of sunlight and the idea of solar panels heating themselves is laughable given the snow and northern latitudes.
[editline]18th November 2016[/editline]
It's a waste. Solar panels are already very expensive compared to how much energy they produce and wasting them by building them in stupid locations is moronic.[/QUOTE]

How does it work with running plumbing ventilation?
I have had to use right angle drills to go up through roof shingles in order to run ventilation, and plumbing codes require them to be run through the roofs afaik. How will these glass tiles affect that? What will be the process of running ventilation through them in the construction process?

The tiles without solar cells in them can probably be cut to fit whatever you need. Will probably just take more careful consideration and the right tools for cutting glass.

Not every tile will have solar cells in them?
Cutting through glass sends shivers down my spine, it will probably be like cutting through fiberglass tubs and the slightest slip up will leave visible cracks and a pissed off client.
