Someone posted a link about Boston.gov being released as an open sourced project on GitHub. I'd like to take a moment to point out that this Tesla website is built on Drupal 7 too. The big thing that both websites get out of the box is i18n support for translation on top of all the tools required from content management. I wouldn't recommend it for websites and services that need many people to constantly update content but to build static pages that are cached is pretty awesome stuff.

Re: Powerwall 2 and Integrated Solar
#72Any idea how much power these things put out when compared with a conventional solar setup? 1:1? .5:1?
That was my question as well, this from the Techcrunch article: "The current versions of the tiles actually have a two percent loss on efficiency, so 98 percent of what you’d normally get from a traditional solar panel, according to Elon Musk. But the company is working with 3M on improved coatings that have the potential to possibly go above normal efficiency, since it could trap the light within, leading to it boun…
replacing my perfectly fine (if nearly 15 year old) solar panel
I wish someone near me would do this, boy would I snap up those second hand panels.
When I was in my early twenties I put together a solar panel + charge regulator + inverter + laptop and run a web server serving a page detailing the setup it was running on.
The entertaining things I could get up to with 1kW or more of cheap second hand panels.

That Powerwall was of a different chemistry, and has been discontinued. EDIT: This is a baller feature: "Always Connected: Monitor your solar energy use in real-time and receive alerts when Powerwall is preparing for cloudy or severe weather. " They're performing weather forecasting, and then ensuring the Powerwall has charged up for a possible outage event. Brilliant.
I cannot imagine what preparation they could be making. Surely the default process is to charge the powerwall at all times if feasible. What extra operation could it do in the event of a bad weather forecast? Other than tell you about it.
Sometimes you discharge. You may decide to not discharge ahead of a storm. If it were just backup, it would be easy, but sometimes you want to consume your storage to save money, or sell back to grid, if you have time of use pricing, or get paid for grid service.

At peak generating times, it may be valuable to sell your stored energy to the grid. If bad weather is coming, you might not want to do that.

#75I haven't looked into it yet, but I'm curious about using utilizing my Teslas in case of emergency for power. With 75kwh+ each (leased so no concern about cycles) I don't think I'd need a powerwall at home.

Hm for that price I can install a natural-gas generator. Have power for days if necessary, full power on all circuits.
Which still ties you to the 'grid' insofar as you need the natgas supply chain, even if you have a huge reservoir you'll eventually run out. Having said that, batteries and solar panels don't have an unlimited life span either. I'm looking at buying a petrol powered generator for reasons other than home power generation, but it will be reassuring to know we have backup power at home, but I don't think I'm allowed to…

30-40$ is probably a very small apartment. A house (2 levels) in Quebec during winter can go easily around 500$ because of the constant heating required.
But you won't get much solar electricity during winter in Quebec anyway would you?
Cooling a house during the summer in Texas can easily cost the same amount if not more, and you get a ton of sun during that time. The point is that for single family homes electricity does not usually cost $40/month.

#78The thing is cloud-connected, remote-controlled by Tesla. That presents a problem. Will the cloud service behind it last the life of the system? Most cloud services evaporate within five years.
Re: Powerwall 2 and Integrated Solar
#79I signed up for the original powerwall and as it turns out it's not Tesla - it's solarcity (I get it, they are the same now). Oh and by the way you have to have the solarcity solar panels installed and running for the powerwall to be installed, which has a cost of it's own. My guess is that this isn't any different given this text: Powerwall 2 is a battery for homes and small businesses that stores the sun’s energy a…
What are your thoughts on the first gen powerwall and solarcity?
Re: Powerwall 2 and Integrated Solar
#80Interesting to see Tesla of all people estimating energy consumption on the basis solely of how many bedrooms your house has, and not adding on how many electric cars you need to charge...
