I'm hearing some nodes on FTTN have only 2Gbps backhaul for up to 380 connections.
That's an average of about 5Mbps. Not enough to stream HD.
Of course, a few people complaining about it have a house with 4 phone ports still connected, so they're backing a shitload of noise up on the line.

FTTN - a 20th century solution to a 21st century problem.

And as an example of that: the three houses across the street from me all have utterly fucking woeful speeds. < 5mbps download. Two of them are on Telstra, one on TPG.
I suspect their internal wiring is probably total shit, despite their relative newness. They're Defence Housing Australia properties, all two stories, and thus might have rubbish wiring.

New panels are doing the job.

@NTA was at a friends birthday yesterday and got talking to a woman going on about the Tesla power wall and how she is following this guy she saw on the news. First installed power wall in Oz. She mentioned his blog "unleash the power something something".
Said, nup, never heard of itπ

New Powerwall coming out. Double capacity (~14kWh compared to ~6.4kWh), double output (7kW versus 3.3kW) of the one I have.
Well... fuck.
Installations begin Feb 2017. If I plug in my details, it recommends 2 of these new Powerwalls at a cost of roughly
The new one is now firmly aimed at the backup market, but at those sorts of capacities will entice those who want to be off-grid. Problem with that is it can change the warranty period.
Speaking of: warranty for this unit is unlimited cycles, 10 years. Apparently. Mine has conditions attached.
I have some early adopter sand in my vagina at this point. But at least, by the time these things land onshore, I'll have already saved about $2K in power bills...
Musk also spruiking roof tiles/shingles that are made of hardened glass and collect solar power. Connectivity is going to be interesting on that front. And corrugated steel roofs still need panels, so I'm fine with that the next 10 years.
-
Wow! I wonder just how far they'll look to improve capacity and cost... as it stands, these new powerwalls will make the ROI challenge disappear for many folk. If they can double the capacity again within the next five years, it could resolve the ROI challenge completely.
We're looking at a knock down rebuild over the next 3 years, my wife is drooling at the thought of installing a Tesla Solar Roof, she's been harping on about the need for a product like this for years. -
@phoenetia based on the price of this one being about the same (installed) as the first version, I think you might simply be looking at multiple units rather than increasing capacity any further.
Our house will consume about 17 kWh a day. Throw in solar PV for day time needs, and one Powerwall will cover it.
House with electric Hot water/cooktop will consume about double that - two Powerwall v2.
Add on luxuries like spa/pool pump etc and maybe 3 Powerwall.
Main thing: figure out what you use on the average day, size appropriately.

Not an upgrade for me Corrugated steel roof on the current house, and loving it!
However, it is a really interesting concept, particularly if they can bring it in at the price point Musk is talking about.
The pain point will be around underlying connections - once you replace the tiles, and have some form of connective media to get the electricity down to the inverter, how is that going to be affected by the internals like roof sarking, bracing straps, metal fittings etc. Is it even advisable on a steel framed house?
I'm sure smarter people than me have thought of all this, but the workforce required to safely install this kind of thing doesn't exist, so I can only assume the SolarCity+Tesla merger is critical, not only for the project to proceed, but also for the labour market to support it.
Maybe the extra strength and insulation will make the sarking redundant? Maybe the fitting system will provide an extremely safe environment no matter what the scenario is.
I reckon they won't sell many in Tornado Alley though

Roofing is so regional anyway I am sure it will be limited to certain markets. A corrugated steel roof would not be permitted nearly anywhere in France. The local town hall would claim its just too ugly. Also steel framed house? Hahah yeah we don't have those I am not sure if the yanks do.
I just love the idea of well it costs the same as re roofing anyway so just coat the whole roof in these things and don't worry about if its south facing or what not you will get some energy from every single tile.

Couple of things

Which country are you based in? NZ is certianly adopting steel framing

In terms of cost, it will be more expensive than roofing tiles initially. They are careful to say the 'total cost' is the same or less, ie conventional roof+power >= special solar roof + much reduced power bill.
This doesn't worry me, because commercialisation and capitalism are very very good at driving costs down. Look at cellphone: 98% reduction in costs in 10 years. Cars are the same - the technology and capability went from 'an oddity that people walk in front of with flags' to a car in every household in a few decades.
I'm excited. I think this is the future, and I don't think it will be decades away.
For info too, Vector here have put in a battery substation - for them it's all about chopping off the peak demand. That is what drives a massive part of teh whole network costing

He's in France, which is an interesting landscape in that it has a metric fuckton of nuclear, so renewables aren't a huge thing there, yet.
Contrast that to the countries around it - particularly Germany which as also big on nuke but is now probably leading the Euro renewables charge, particularly in community-owned solar. They have several companies like Sonnen who are turning out quality batteries and solar kit, and with the German bent for engineering, doing well.
The low countries are heavily into offshore wind as its abundant. Spain is going deep into concentrated solar thermal (but doesn't have anything like a decent domestic solar rebate). The UK is now moving to more offshore wind and encouraging solar as it shuts down coal and awaits Hinkley to come online (some time in the next ten years and 6 billion pounds).
Here in Oz, we're the proving ground for a lot of this tech, when the shareholders and gold-plating can see past the now money into the future money.
It was announced yesterday that the dirtiest of our brown coal stations in Victoria would close.
Sucks for the workers, but they'll be generously compensated and retrained. The district should now throw itself into the practice of decommissioning these old power plants (there are another three around) and turning the LaTrobe valley into a pinnacle of renewable energy farming.
The great thing is the power transport infrastructure is still there, and a mix of solar and wind farms would kick arse, particularly once the big dirty power station is removed from the horizon and replaced with something better.

Yip in France they tend to hold onto tradition a little bit longer. I can't speak to much about new build houses as they don't exist in Paris its all concrete slab appartements that are going up. In the countryside there is not a lot of building but from what I understand its mostly traditional timber framed or prefabbed concrete.
Everything has to fit in with what is already there so if you fancied a copper roof or something you would have a really hard time selling that to the planning people.
There is a decent amount of wind generation here you see it driving around the motorways but as NTA has said its nothing in comparison to the Nuclear.
I have just picked up a place in the south and will be looking to get into adding some renewable energy generation in the coming years. So very interested in the developments in this area.
