Anyway, the idea behind this is that you've got a unit that can charge itself via solar power- then, during the night, that power can be then recalled. Or, you can charge it during non-peak times from the power company, then pull power off of it at peak times, thus saving you money, and also reducing strain on the grid.
It's the last key ingredient that's plagued a lot of solar installs. Instead of selling power back to the grid for shit, you can keep your power.
For places that get a lot of sun, this is an excellent thing.
This isn't a new or innovative technology at all, Tesla is just marketing it in a way that has mass appeal. Basically the Apple of solar/electric power, the difference being instead of peddling vapid consumerism, they're peddling a habitable earth.
I hope solar installations are going to go down in price/be more competitive. the prices are fucking ridiculous right now where i live. People claim to be able to retire after doing solar installation for less than 10 years.
Generally designed to work in conjunction with solar panels or such, so instead of selling your excess power to the utility, you store it into this. If you don't have solar panels, there is some utility in that you can charge them up during non-peak hours when your electric utility charges less, then draw off of them during peak times.
>>47824670 This picture is wildly inaccurate. First of all, black people don't grow weed, it's actually not the easiest thing to do and niggers just can't do it. Niggers will definitely SELL weed on the streets. Secondly, there's no way some nigger can afford solar panels and a bunch of Tesla Powerwalls.
>>47825874 >Secondly, there's no way some nigger can afford solar panels and a bunch of Tesla Powerwalls. Selling drugs is really lucrative. Problem is that they don't save any of it. Money they get is blown on stupid shit like jewellery, fashion, or the usual dumb nigger shit. They could if they wanted to.
I wonder if this is really going to be more cost-effective than selling back energy to your power company. Of course it's probably cheaper to use your own power instead of selling it for a low amount of money, but storing energy is less efficient than using it directly, and the batteries will have to be bought and replaced at some point.
>>47826052 >I wonder if this is really going to be more cost-effective than selling back energy to your power company. If doing this is subsidized 'cause it's renewables (like in much of Europe), then probably no.
>but storing energy is less efficient than using it directly Yes - getting it up to 120/220V or whatever from ~4-12V or such and transporting it elsewhere also is less efficient than storing it in a modern Lithium battery at ~4 or ~12V, though.
>>47826090 Then I wonder if this Tesla thing can be directly hooked up to your solar panels, because that would be efficient indeed. I don't know how far the transport is though, it could still be more efficient if you're basically powering your neighbours.
>>47826130 You still want a MPPT or battery manager in between, but maybe that is included.
> it could still be more efficient if you're basically powering your neighbours. If you have an "off grid" equipped household with all 12V device, you can save yourself the voltage step-up conversion there.
>>47826153 It would be cool if you just had a big super efficient 5kW PSU in your house, and just had 12VDC everywhere. I can't really think of anything that doesn't convert power anyways, especially now that led lighting is cheap as fuck. Maybe stuff like a vacuum cleaner actually has a 230VAC motor, but I don't think 12volt motors are necessarily worse, right?
>>47823373 The way my parent's solar works they actually get paid more for putting power into the grid than buying from it. So they do any power intensive things like pool pump and washing at night to get more money. >power companys in charge of common sense
> Maybe stuff like a vacuum cleaner actually has a 230VAC motor, but I don't think 12volt motors are necessarily worse, right? Actually, I don't know about that, but you CAN still use an inverter for individual devices that require it, especially if you buffer off a lithium battery it shouldn't be much of a problem as such.
Just a little lossy, but I hope vacuuming isn't amounting to much of your total energy budget anyways... it should work.
>>47826233 >>47826252 Subsidies / very different rates for renewable energy will make selling this power to the power company more efficient, yes.
> Completely retarded and financed with taxes. Semi-retarded, this is the easy way to financially compensate owners of solar installations. Power companies aren't going to be interested to send someone over to look at your additional in-house power meter (and be it to inspect it's not rigged) and pay you for using that one too.
>>47826090 You can use an automated system that redirects energy: if the solar power is not used then it will be stored in batteries. If the solar power is not used and the batteries are at full charge then it will be uploaded to the smart grid.
Anyway, just like for the cars, Elon Musk is pushing a market not for greed (he has the money) but for good. I don't like Apple analogies because Apple is exactly the opposite: they do useless things for greed.
>>47826546 The problem for us is still the price though.
>>47826626 Depends on where you live. You'd need more in the winter because of less sunlight. If you get snow you need some way to keep the panels clear, heating them would of course require more power.
>>47826500 >So, for a 10KW/h implant you should pay 3,5k for the batteries, and at least 5k more for the controller+inverter+installation. Yep, something like that.
And if you use micro-inverters close to the panel rather than one inverter per string (has a bunch of advantages again - efficiency and reliability gains, easier fault isolation, ...), it costs even more.
>>47826780 (cont'd) Maybe a hose up to the roof so you can easily clean the panels.
Mounting racks / spacers of sorts so you can mount panels them "air cooled".
~20-30% extra panels or a conventional generator maybe so you can at least run all the essentials on the 30-50% power you might get on cloudy days (which may come in sequence).
Probably a good inverter or two so you can draw 120V or 220V or whatever with the more common household appliances anyways. (12-48V are great, but not everything is that, and buying a lot of exotic devices will cost more than the inverter).
I have a question not directly related to these Tesla batteries: do new phones alimentate themselves while attached to the ac line other than charging the battery? (I mean, like in newer laptops the battery is not constantly drained and charged..) Because if so, if I wanted to charge my phone directly to the solar panels how does it manage to know I just want to charge the battery and not fry the internal circuits with an instable voltage?
What are you in at? I bought some at 170 basically just speculating on an earnings release. Of course it was wrong but I didn't mind as I was willing to let it ride. Sittin on a tidy profit but nothing out of this world compared to the potential
around 2010 in Canada there was a huge push for renewable energy. there were a ton of grants available for anybody installing solar panels, wind turbines etc. A bunch of independent contractors popped up demanding big bucks for panel installs, then pocket all of that delicious government money.
that only lasted about a year. they stopped giving out grant money and all of these contractors went bankrupt. when the dust settled, homeowners realized that their solar installs were actually costing them money and not saving any energy.
a bunch of people got sued. it was great.
if the power wall takes off, possibly in combination with some better solar panels and power management, we could have a really good thing going.
>>47829171 >The biggest photovoltaic plant, wich is in my city, was built by an american company only to benefit from incentives. well, hopefully the solar plant is paying for itself.
>In December 2010 SunPower has completed the sale of Montalto di Castro solar park to a consortium of international investors hmm.
here in canada, most of the big companies (not just energy) are now owned by international investors. the government is trying to privatize a bunch of services to save money and cut taxes, but old white people keep saying they're "selling everything to China".
>>47830276 A first world country like USA where the infrastructure is over 50 years old on average and collapsing almost every day, where you have a whole dozen inspectors states with a few thousand dams that can't inspect shit and manage only a 5% quota? I'd take a country where power outages are due to infrastructure being updated over a country that doesn't even have money anymore, or will, to repair its infrastructure and waits for everything to go to shit at once.
>>47830878 Judging by the crazy safety and financial policies Tesla has on their cars, and the crazy ways they go to ensure the everything in their shit is safe and destruction-proof, i'd say you can feel safe in those regards.
>>47830992 It's not hard to get a solar panel system these days, You can even DIY install it if you're a man who has a basic understanding of how to work tools, but if you've got ovaries, someone can install it for you.
its supposed to kick in during peak or critical power use when cost per Kwh goes up, saving you some money by not drawing power from the grid to run your 5Kw air conditioner. but i think this tiered service is only mandatory in california. all other states either dont have such a thing (its a flat rate) or they give you the option to opt-into a tiered service (TECO does this)
also you really need to understand math if you are going to figure out if this will save you money. >there is power lost when charging the battery >there is power lost when discharging the battery >the battery will need to be on a trickle charge to maintain its efficiency longer
depending on your set up, this might cost you MORE money than save. its also designed for solar in mind, so thats another expense to consider.
Thats the question. we know the battery is $3500, but what we dont know is its efficiency, and life span.
that generator could last 20+ years easy provided you dont neglect the fuck out of it also they make natural gas generators which would remove entirely the need to keep a huge tank of fuel lying around to go stale/bad
Those lamps you use for growing weed? They are hot. Really hot. Most big grow ops are found by helicopter with IR cameras and are perfectly concealed to the human eye, but when hit with IR imaging, are glowing hot on their roofs.
They literally fly over homes and look for who has the hottest roof on IR, get a warrant with that alone, and raid the shit. Why else would someone's roof be so much hotter than the surrounding buildings?
>but muh greenhouse is hot
Not that hot. And more to the point, just having a greenhouse could be probable cause for them to raid your shit and search it if you don't have a commercially zoned property or a permit for selling agricultural shit.
>>47830303 a weed grower, for 2 plants can potentially make $3000 (if both plants produce about 6 ounces dried) in 3 months for very little work (soil).
hydro is a bit more work, mainly because of the cleanup involved at the end, but all told, you might spend 20 minutes a day(averaged out) tending to the plants (for 2 plants remember) which works to something like 30 hours total worked for the 3 months
