  1. Ben, this video is not about Andrew Yang and therefore gets a downvote. It's my new internet policy. Please adjust accordingly.

  2. Thanks for watching everyone! If you'd like to get a solar quote without being spammed by installers check out Energy Sage at https://teslanomics.co/energysage – it's what I used for my own Solar system a few years back and love how they lay all the data out

  3. Our Powerwalls have been down for a week. Tesla can't come out to investigate and fix them until December 4. 🙁
    Also, since we generate more PV power in a year than we consume in a year, it doesn't really make any sense for us to use any setting other than "backup". There are some efficiency losses in the Powerwall charge and discharge cycles, so we come out the best financially to simply have a flat rate plan and a single pool of excess power credits with our power company. With a nights and weekends (cheaper) rate plan we ended up with two pools of power credits, which meant we had to try to manage our power usage by time and day. While the rates were cheaper on paper, the reality is that we don't end up paying the higher electric rates the flat rate plan has due to overproduction of power by solar. Anyway, hopefully Tesla will be able to get our backup batteries online soon.

  4. I've got a Model X (w/ lifetime free supercharging) and a family of 4, living in Orange County (Irvine). Do you recommend me getting the powerwall for my situation?

  5. Fantastic Video Ben I’ve been wondering about this! For your data visualization how did you do that? Is that something you can download as a csv from the Tesla app?

  6. So with the cars drawing so much power could Tesla not have the cars also act as a power wall from there batteries when connected obviously there’s times you probably wouldn’t want to do this like say in a long term outage so it doesn’t turn your transportation into a brick I’m sure Tesla could come out with a update but maybe I answered my own question?!?

  7. You have two electric cars. Each car is the equivalent of 6-7 power walls of storage. Can't you use them as your battery back up instead of power walls?
    In fact purchasing a used tesla at $30k and using it as a power wall is cheaper than buying the power wall.

  8. More good info, Ben, thanks. I really wish I could make the economics of a set of Powerwalls work for my situation, but here with our short, dark, cold Northwest winter days nothing beats a good old fashioned standby generator when the wind blows.

  9. Ben you do have the numbers for the warranty. You have the data showing how many times the batteries can be discharged before failure. The warranty is very, very conservative. You know this. You have the data.

  10. When the solar roof and powerwalls were first announced I was very intrigued. But I live in Tennessee and only pay about $0.08 per kWh. It doesn't make sense for me.

  11. If you average $150 a month in electricity. I don’t see how purchasing or leasing a $15,000 solar system would help. You would practically be retired by the time you break even at the prices they are charging now.

    My neighbor has a great solar system and all electric cars, no gas. He paid $20,000 for the solar system and his average electric bill before that was about $150 a month he owns the same exact house model as I do. He basically only pays for the hook up to Southern California Edison. Edison gives no credit whatsoever for putting electricity back into the grid from your system and then charges you $500 a year to have a solar system that’s a whole Lotta bullshit.

    It’s going to take my neighbor about 10 to 11 years to break even on his system maybe longer due to the $500 a year he’s being charged by Edison, it may be more like 12 or 13 years before he breaks even. By the time he breaks even on his solar system a new solar system will cost half the amount.

    I see solar systems in the next 10 years coming down to about $5000. I’ve watch them come down from $50,000 all the way down to $15,000 in the last 12 years.

  12. Hmm.. the power companies could purchase a fleet of used tesla cars and use them as mobile peaker plants. Drive them to where their needed and power the grid locally even segment the grid for fire protection. Additional electronic modules would be required to manage power switching simular to the power wall designs

  13. Ben, I believe in Stormwatch, the Powerwall prioritizes being charged from whatever means necessary… so it will pull power from grid to charge itself.

    From what I see, during Normal operations, the Powerwall will only charge from Solar. Never from the grid.

  14. Stellar breakdown as always, Ben. Looking forward to breaking my broke-ass-millennial chains some day and affording a house with one of these Powerwalls.

  15. Either I am mixed up or the slide entitled When Powerwall Makes Financial Sense has a couple of the criteria backwards. You have both Solar and Net Energy Metering but the slide says No Solar and No NEM. Based on your comments, I assume that your average per kWh is over $0.14. Don't you need to have all three of these criteria for the Powerwall to make financial sense? Solar + NEM + expensive electricity from the grid? If you have neither solar nor NEM, I don't understand how you could generate a financial benefit, regardless of your cost per kWh.

  16. At the moment, I don’t intend to get into solar power just because where I live, right now my electricity is actually pretty cheap, but the power does flicker on and off occasionally, not really a big deal but it is a minor annoyance to me, some things I have are best left running 24/7, so I think that Tesla powerwall would probably fix that, so that is something I could consider.

  17. Hey Ben… That video was very punchy and only 10 minutes and I liked it. Pretty sure Elon is going to hit the big time with these powerwalls. A lot of energy companies are going to go out of business but Elon's infrastructure is pretty fireproof. Just think about not having power if a catastrophe was about to hit. These powerwalls make big sense.

  18. No wonder California is broke. They are giving too many credits to their citizens. In Colorado, if I have a surplus on my solar system at the end of the month, Xcel energy pays me pennies, not 53 cents/Kwh. No time of use here in Colorado.

  19. Great video Ben. Very informative. What were your costs in doing this ? And what does it take to cut the cord from the grid totally ?

  20. What are you talking about $500-$750 credit per year? I am in California too and didn’t know about an “annual credit”

  21. As A California resident without Solar PV (thanks to Housing Association Nazis, and roof orientation, and trees),
    what I'd really like is to be able to charge the Powerwall FROM THE GRID at off-peak times and then use that power at peak hours.
    Then I could have the Powerwall PRIMARILY for blackouts, but also save a little on the cost every day.
    (I believe the Powerwall cannot charge from GRID, only Solar)
    Of course, I expect PG&E will never permit this mode as it hits their bottom line (even though it levels their demand curve)

  22. Hey Ben,
    Love your channel. I've been following you for some time.
    Have a look at The Energy Sovereignty Project on our channel. We are in our 11th month of a yearlong study on exactly what you are talking about.
    We have identified the amount of storage one REALLY needs to be able to pull off what you are talking about.
    The thing about using the powerwalls/solar to power an EV is that it dramatically reduces your ROI period once you offset the gains you already get from your power bill with what you save in gasoline.

    What makes it possible to use batteries for EV charging is to have enough excess capacity in the battery so that once you return home after work that you can then take from the system.
    As you pointed out, however, this is still pretty much a "break even" proposition and even then, only if the consumer can leverage some kind of incentive like California's SGIP.
    Economies of scale, however… as well as Tesla's new "Million Mile" battery, will drive prices down further and give consumer confidence in a 20 year product.

    Thanks for posting this. Great information.

  23. Buying power low and selling it high can only lead to an unfortunate outcome as more people adopt power wall and solar systems. Either the power utilities will go bankrupt or they raise the price of energy thus cancelling your advantage. In addition the lower income brackets with no solar or storage are forced to do without power for heating or cooling thus speeding up the demise of the utility grid.

  24. Crazy Idea:

    if super off peak charges are 9cents/kwh and on peak back to grid charges are 53c/kwh, why dont use 1 powerwall just to charge at super off peak and send back to grid on peak, which makes powerwall to earn money for you.. 😛

  25. Buy at 9 cents and sell back at 53 cents? Forget Bitcoin, invest in PowerWalls! Is there a limit to the number of PowerWalls you can have?

  26. I dunno about the US, but over here (germany) the average car drives 40km a day – which comes out to less than 8kWh…which should be well within the range of a powerwall's capabilities.

  27. California is not wealthy, when you have over 60k homeless people shitting on the streets, living under bridges and needles everywhere, it's a dump, also not even able to have the infrastructure to have electricity, I consider California a trap, where people are stuck with million dollar homes that are not worth more than 300k elsewhere

  28. Ben, I also live in sunny San Diego but have been getting slammed with an SDG&E bill despite having solar and charging during off-peak times. we purchased our 75kw X at the end of December and started receiving our first SDG&E bill in 6 years that next month! We looked into adding more panels however we are getting quotes of around 15k due to "our system being maxed out." After watching your video, this is the first time I have thought about getting a powerwall charger. We own our solar and it produces around 26 kWh/day but according to SDG&E we are using an average of 35 kWh/day. Do you think that having a powerwall will work for our household? ANY thoughts are appreciated. Thanks!

  29. Excellent breakdown. For me (in South Carolina) it doesn't make a lot of sense to get a Powerwall, as I have net metering and my energy company doesn't offer 'off-peak' rates (same rate any time of day/night). Also, I almost always use more electricity than my solar panels make. So unless I'm missing something, I can't think of a good reason to get a Powerwall for my particular situation (I don't mind the power going out once or twice a year).

  30. Are you planning to eventually add a geothermal heat pump? And given that you are in CA, have you gone and out a lot of work into energy efficiency? (Sprayed insulation into the walls, insulating blinds or curtains, upgraded appliances, etc..)

  31. what about just enough energy for vehicles only. how many tesla poweralls would i need if say i wanted to charge a tesla model x each night to a full charge?

  32. Why do i get “this video is limited” and claiming i need to login, it is annoying as i cannot stream it to the tv (even when i’m logged in) this is only happening on a very small set of video’s

  33. Powerwall makes you $2k per year. At 13.5Kw hr x $0.53 (peak) = $7.16 less 13.5Kw x 9 cents (off peak) = $1.22 – Makes a Daily Net Positive of $5.94 – Monthly $178 – Yearly $2,168 – Cost is under $8k, so 27% ROI.

    I would certainly stock up on powerwalls if your Peak / Off Peak is 5x.

  34. We live in an all electric house in the northeast and are always at risk of losing power in bad weather. W bought our two Powerwalls primarily as emergency backup, instead of the Generac we were considering. There are pluses and minuses with both, but the overall utility of the Powerwalls won us over. In summer they provide most of the power the house uses, including charging our Model 3.
    Strategic timing on when we charge the car means I can get 50+ miles of range from the solar and Powerwalls combined and still have the batteries charge back to 100%. Then we run the house all night on the Powerwalls. That is something you can't do with a Generac.
    Primarily the Powerwalls are a security blanket against outages. Everything else that they let you do with your stored power makes them an awesome tool for saving money.

  35. If you're living paycheck to paycheck and you're so poor living in California you worry about food spoilage or sleeping in your car for the AC, then how are you going to afford this system?

  36. That’s combination of time of use metering, solar net metering, and the power wall is terrific. Our utility doesn’t offer TOU and net metering at the same time. It’s one or the other.

  37. Where did you get the calculation that if you have no solar panels, no Net Metering and power is greater than $0.14 per kWh, the Powerwall is not a good deal? I've figured this out myself — too many trees for solar, Net Metering is available but the difference between Time of Use Plans and Flat Rate Plans is about $0.057 per kWh, which would exceed the expected lifespan of a Powerwall before ROI, and I pay between $0.10 and $0.13 per kWh, average $0.117. Would love to see the numbers and where you got them.

  38. Only if consumers would stop acting like the experts. And started listening to us professional Solar consultants. There wouldn’t be a need for this video. Smh

  39. Ben, you need to move. I live in Roseville CA. The city makes its own power and we have no outages. I have solar with net metering and anything over my generation is billed at 14 cents per kWh. It is a fantastic place to live if your stuck in CA.

  40. I wondered if the Tesla powerwall had the vehicle to grid (V2G) facility? Both of your cars effectively become mobile batteries. If you can buy overnight at 9 cents and sell back at 53 cents, I’d plan to sell back up to 75% of both powerwall and cars.

  41. I've run the numbers and in Texas unless I'm going to stay in my house for 10-14 years it doesn't make sense yet. Sometimes I want to do it just because it's cool 🙂

  42. The batteries in your cars are much bigger than the batteries in a powerwall. Does Tesla prohibit using your car like a powerwall? I guess that would cut into their energy storage business…

  43. Is Tesla's subscription service a better deal? 65 bucks a month for a small system. Will take 20 years to break even vs buying.

  44. Only in California will they pay you that high a retail , I have 2 powerwalls in Arizona where you get the wholesale price for whatever you send back to the grid which is less than 3 cents a KWH so I set mine up to never send to grid if i can help it by using all my excess solar production to charge my EV, but in the summer time here all excess power generation goes to the AC
