Using Tesla Powerwall 2 to Pay Less than $1/Day for Electricity

a few years ago my wife and I sat down and made a family sustainability plan with the idea that if we were smart about it we could help the planet by reducing our emissions and save a ton of money so in almost three years we've accomplished just about everything on that list and that has led us to be able to pay less than one dollar per day for for almost those entire three years so let's dive in and I'll show you what I did to save money here and the planet and see if it might work out for you our strategy is actually pretty simple and it has mostly two parts let's start with part 1 going solar Solar is something that isn't right for everyone but is right for a lot of people and now thankfully Google has this really awesome tool to help you see exactly whether or not solar is gonna be right for you so on Google Project sunroof it's a really cool tool where you can punch in your address and see whether or not solar is right for you in this case I just want to explore some areas so I'm gonna go to the data explorer and have a look at Seattle a place that you may not think is one that's right for and looking at the results here you can see that yeah the sunlight on the rooftops aren't great but 85% of buildings are solar viable meaning that the way that the roofs are structured and everything else would do well to add when you go down you can see the roof space the number of roofs all this kind of stuff the types of roofs the installs all that kind of stuff and see exactly what the potential is for this market so let's go over now to an area that does work extremely well where I live in Southern California and here you can see just the bright yellow compared to the darker shady air colors that we saw in Seattle which just gives you an idea of how good an area is for solar now again you can punch in your exact address here and get more details but I actually have a better tool for that that's a bit more actionable and this is the one that I used to go solar about three years ago and this tool is from energy sage and it's a solar calculator like many of them out there this is the actual one I use though so I wanted to show this because I think it's one of the best one's out there you punch in your address like I've done here and you drag the map the little dot here over your actual roof to see exactly whether or not it's right for you then you punch in your bill mine at the time was right here around a hundred and fifty dollars and it runs the numbers for you it looks at the roof size orientation rates and sent 'iv all kinds of stuff and seeing exactly what's going on with solar in your area then it gives you the results and the big deal here is it shows you the results how much money you're going to save over the life of a solar installation so as you scroll down you can see that there are three different options it presents paying in cash doing a $0 down loan or a $0 down lease and this is an interesting way that a lot of people are being able to get solar without having to come out of pocket then as you scroll down you can kind of see how that works with in terms of the payback period and then property value increasing etc etc so looking on Energy Sage you can really quickly just get a sense of the value that solar may bring to your specific address and all the different kind of financing options now let me address one thing that may have popped out there is that this is a long term investment this isn't something that you're looking to save money on your bill tomorrow but it can be something that will start to pay back much sooner depending on where you live and your energy needs so to get the actual real detailed information you can do what I did which is to sign up an energy sage give them your electricity bill and do the map thing and show them your roofline and then you get bids from installers without sharing your personal information with them meaning they're not going to spam you this is literally what I did to get solar so go check them out I have become an affiliate for them but there's no added cost to you and it does help kind of grow the channel and everything so I'll put a link in the description down below if you want to check out energy sage and take it to the next step prior to getting solar installed at my house I was paying a hundred and fifty seven dollars a month in electricity which included me working from home full-time my wife and one year old which were also home full-time and our one electric car that we had we purchased immediately following our install of solar our bill dropped dramatically averaging $15 a month for the next 12 months which includes these non by passable charges which are right around 10 to 12 dollars a month I know I know they want you to pay just to be connected even if you're not taking any energy out but hey there are a lot of things that I pay more than 10 bucks a month for that are far less important than having reliable electricity so I'm okay with it then we got another electric car a Model 3 and I was charging outside of home so nothing really shifted much but once I moved back home for my studio in December of 2018 our bill shot up dramatically again at that time I dug in and found that I could switch my electricity plan to where I got charged different rates at different times a day and then control when I charged my cars to kind of wash that out and save more money so I did that and the price started to drop again in our bill started to normalize so while this wasn't a part of our strategy initially it turned out to be a super valuable piece this whole time of use rates or tou plans as you may see them called you can use it to your advantage if you can control when you consume your energy versus when you send it back to the grid and the way it works is that at certain times a day you'll get charged a higher price than others and if you can then be selling energy back to the grid at that time you will be essentially making more money and then go back and refill that at a later time when the prices are lower and this is where our second major part of our strategy came into play these are our powerwall with our tesla powerwall being installed in august of 2019 we were able to once again start charging both of our EVs at home and save even more with what's known as peak shaving the idea here is what I kind of mentioned earlier where we have a power wall and it allows us to configure when we are going to pull energy from the grid versus our own batteries so with this what we do is we charge our cars from 12:00 to 6:00 a.m.

At a super low rate 9 cents per kilowatt hour then we take on and pulls up and we start living off of our for most of the day then when the rates get super high at 4 p.m. we flip over to running all of our energy needs off of the power wall this way any excess is being sold back to the grid so we're buying energy at nine cents kilowatt hour and selling it back to the grid at 53 cents a kilowatt hour buy low sell high simple right this also works because in California like 37 other states and territories in the US we have what's called net energy metering or nem this is where as an energy producer I am able to sell energy back to the grid and get credited for that and the way it works specifically is I am credited at the same rate of which energy would cost during that time so when I switch my house to running on my power wall at that peak rate at 53 cents a kilowatt hour and then all of my solar energy which is still being generated goes back to the grid I'm being credited at that 53 cents a kilowatt hour during that time then when the prices drop to nine cents a kilowatt hour from that 12:00 a.m.

To 6:00 a.m. what they call super off-peak I fill up my cars and if need be I fill up the power walls now this might sound a bit fishy like it's not gonna work but the deal is this really helps the grid by essentially taking my house offline during the toughest time when it has that peak demand so the energy companies have no issues with this and the states and everyone else have regulated it so that way I'm getting a fair deal by doing this and it does help the long term strategy of maintaining the grid and what I do is I actually kind of take it a step further by mostly filling up the power walls from solar so that nine cents a kilowatt hour rate really is just reserved for charging my electric cars which with 80 kilowatt hours in one and 90 kilowatt hours in another is an absolute ton of energy thankfully we're not driving a ton right now but those would absolutely destroy the power walls in terms of just eating up all the energy there and going back to the grid anyways leaving them completely depleted for the following day so to take it a step further the way I have it set up is I do that peak shaving technique where my house is essentially off grid from 4:00 to 9:00 p.m.

When it's that highest rate then I go back to the grid when it's the lowest rate of nine cents a kilowatt hour from 12:00 to 6:00 a.m. is when I pull the most energy and then other than that I'm living on solar and feeding as much back to the grid as possible any excess that is from you know the energy being used during the day with my wife and two kids home and me here in our home studio working so if you add it all up over the past twelve months I've paid an average of 86 cents per day for electricity and since the power walls that average has dropped to 60 cents per day now remember that isn't just the energy being used in the home for air conditioning and TV and whatever else that includes to electric vehicles so that means all of our essentially gas money that we would be spending as well is included in this rate of 60 cents per day since we got our power walls installed now of course there is a cost associated with giving solar and power walls and setting up all this stuff but I'll save that for a future video when I have kind of more data and I can give you a more complete picture but right now if you do want to go a little bit further check out this video over here where I talk about my power wall install how it went and the cost and everything that I went through to get these two power walls installed at my house so thanks for watching let me know what you think please like share subscribe leave a comment down below and don't forget we free the data your mind will follow I'll see you back here in the next one
