So it appears Tesla found a bug in their app after watching this video that accidentally counted all production and usage totals as DOUBLE their actual numbers. Doesn't affect my payback timeline calculations, but it does make more sense that I was seeing ~4000kWh of production in a month, not 8000 🤓

[@merojeff]

Why didn’t you factor any SREC’s into your calculations? Huge variable when talking about ROI, especially with the production as high as you are showing.

[@sreejithprakash13s36]

[@hbjigcc]

Yes, you cannot produce 350 kWh of energy in a day with a ~40kW panel array. At your latitude, four times kWp in the best case scenario makes more sense.

Utilities fight tooth and nail to make these programs as favorable to their business models as possible.

[@Masheeable]

I disagree strongly. This user claims to use up to 200KWh/day as an average usage. This is x5-x10 more than my lifetime experience of daily usage (not inc elec car). It's also common to have 2-5KW roof top systems, not 30KW. There was nothing about the numbers in this video that matched a normal setup. It was literally a top 1% of the top 1% of rich people's reference. With all that said... a 7-10yr return on investment is a solid conclusion and matches the curve of return on smaller setups.

[@teknoid5878]

You can power 4-5 houses with that.

[@kevinwhite8836]

​@OurWorldUncovered Absolutely. I have 23 panels and a Powerwall and thankfully a South Facing Roof (South East Coast). On a good Spring / Summer day, I have had upwards of 65KW per day and over the last year, around 12Mwh total. I have not paid any electric bill since it was installed (thankfully was on the Tesla Energy Plan which is currently 24p export and 24p import, however they have now cancelled this Plan which I loose from Feb 2024 😕). So basically the grid is like an unlimited battery for me, until the Plan finishes. We also charge 2 electric cars, which by a clear mile are the biggest draw on power. At current energy prices, it will have paid for itself in around 4 years, so about 2 years left for me. The caveat is though, you need the right location, as roof positioning and clear sight (no obstructions to light such as buildings and trees) will make a massive difference. Our South Facing roof gets sun all day long, but the other roof only really gets sun during Summer and that is not all day.

[@CGGeek]

Really interesting, thanks for sharing this data! One thought is.. The solar panels are under warranty for 25 years, but probably not the power walls? As we all know batteries don't often last too many years, so the power walls would likely need to be replaced after 10 years? Adding a longer payback period, as I'm sure Tesla battery banks of that size are a large cost.

[@YolandaPlayne]

Yes, the payback period would be a lot shorter without the batteries. They're expensive and die before they can pay themselves off. They're really only a good idea if you don't have net metering.

[@SemiZeroGravity]

10 years is a number that also depends on how much you charge and discharge it depending on depth of discharge it might actually last longer.

[@Imbatmn57]

Tesla batteries probably don't last as long, I've heard at least 3 people complain about the tesla power walls, a solar installer even recommended not to use the tesla wall batteries.

[@bitcores]

I'm seeing a lot of estimates from 10 to 25 years. Seeing they are batteries it is going to come down to cycles, and having excess storage will increase the longevity of the banks.

[@nathanlee105]

The coolest thing in my opinion, that you mentioned is the seamless transition to going off grid when there’s a power outage. That’s crazy that you don’t know that a power outage happened because you’re already running off of solar and battery power and not off the grid so nothing changed. If I was in the situation, imagine myself watching TV at 10 o’clock at night and looking out the window and my neighborhood being completely black and then I’m going. “ huh We must have a power outage right now.”

[@fetB]

[@jessecortez9449]

Typically, governments from federal down to local, don't want you self sufficient and off of their grid. They see it as too risky and that they have to protect you... from yourself. For years, people that have tried to be fully self sufficient have had to fight their local governments legally to even get close to full self sufficiency. Same goes for having a decent sized garden (it's not like during WWII when they wanted everyone to have a victory garden). This resistance might be changing a bit but never expect government to a) move fast and b) for government to give up (political) power that citizens gave up out of comfort and security. I'm sure with all the ESG regulations being imposed this decade you'll be nearly fully self sufficient but they wont let you cut the umbilical cord they have you on. There will certainly be some carbon tax that you'll have to pay for using too much of the power that even you have generated.

[@nickel36]

​@@CharlyLownoizesome quick math shows he would have gone about 200000 km in his Model S Plaid assuming the other commenter is correct in saying it's 5x average, to make up that difference. That would be a crazy amount. He does travel a lot to play professional Ultimate Frisbee, so his car usage is likely much more than average. Also quick googling says the average American does 20000km per year. No way he does 10x that. He does have a large house (as he says in the video), and it makes sense given I'm sure he's quite wealthy. And no doubt his house is full of tech. He runs more powerful computers than most. Even after those factors, and assuming 5x the average is correct, that's still a lot.

Probably the best MKBHD video so far. My PhD was about optimization of smart grids, including smart houses with solar panels and EVs. I'm saying this because I understand how much research and effort in general was put in building up for this video. The most difficult part in this process is how to make it simple enough so that the general audience would understand most of what you're talking about. I think you did a very good job in making it as simple as it can be, although I understand that it still could be very complicated for some people with all those numbers and graphs. Overall, well done Marques! An incredible video that even professionals and researchers can find it useful.

[@mkbhd]

[@habajaba9603]

Yes. Most people will not take time going through the numbers, even if it is incredible tech. I think you will also find it very interesting to check out bio electricity. There's a company called Bioo that makes electricity 24/7 using living plants. There's no toxic waste. Just plants doing their thing and simple devices using their waste products underground to create electricity.

[@wayando]

Why would it be complicated though. Seems simple enough to understand. Solar produces power to use and to charge ... Net metering takes excess and charges you less when you pull from the grid ... Batteries store excess and you use when the sun is down. The only thing missing, maybe, is potential for reverse charge from a car ... So charging a car and pulling power from a car at calculated times.

[@NisYT]

​@@wayando Most people once you mention the word "Math" pass out and their brains turn to gummy bears.

[@wayando]

​@@NisYT... Very true. What I have noticed about Solar systems is that if someone doesn't like math they could just copy a friend's system who has approximately the same usage patterns ... Then automate everything using software and timers. Personally, I have a completely off-grid system ... And these require the most math for planning before and during usage ... I can do math but I avoid complicated daily calculations if I don't have to do it. I copied my system from someone, but because I didn't want to risk having certain problems, I put in place certain "safe guards": 1. I put slightly more solar than I need, and divided them into 3 separate groups bringing down power separately ... This helps with figuring out sources of issues, and also factoring the side facing the sun. 2. Batteries are expensive, but at the same time it's better to have more battery because of depth of discharge ... So I got batteries is 3 rounds, and have them separated into 2 battery banks that operate separately. I was just eyeballing the performance by checking the discharge level at 6am before sun rise. Then I upgrade as necessary. The whole battery was in place in about 6months. Heavy usage items are controlled by timers and strictly limit their usage to day time. Et c. Diesel generator on standby. Just Incase. But it has been idle for 3yrs now.

Great review Marques, especially the discussion at 26:00 on Snow build up. Snow / ice dams can be a big issue with regards to roof damage/roof collapse. For roofs without solar panels, there are wires you can install on the roof to melt the snow/ice (similar to on plumbing pipes). I wonder if there is something available specifically for solar panels (a heated frame perhaps that goes around the panels to heat up during days when there is heavy snow/ice so it can melt the snow faster).

[@vpsjdon]

Okay so I need some clarifications on a few things: 1) MKBHD uses around 4000 KWh of electricity every month. Is that normal for an average American? Cause my household's MAX energy use in the peak of summers (May June) is about 700-800 units a month, with about 2-3 ACs running pretty much the entire day/night -2) How expensive is electricity in America? 54000 units of electricity would've cost MKBHD ~9000 USD.. That comes out to about 5.2 USD per unit? Isn't that like a lot? The tariff he showed earlier were displaying the cost in 30 cents per unit or something- Whoops. I made a Maths booboo. My bad.

[@ChillOutDood]

@@vpsjdon that is not average usage, even for an ev owner. I’m assuming it’s due to the amount of specialty equipment he has running around the clock due to his profession. Last summer we were seeing that type of consumption due to the historic heat wave. We do have certain areas that are more affluent that can average that type of usage but they also have ADU’s , wells , stables , irrigation systems etc. 700-800 is more common usage, also depends on how much they charge at home vs at a charging station. To be on solar you have to be on time of use, so the rate varies depending on the time of day, I’m on the west coast so I can’t speak for where he lives. But highest cost is between on peak (4-9) and lowest overnight (super off peak) which is when you want to be charging your vehicle. If you’re on an EV rate it’s about 16 cents a kilowatt but you pay a monthly service fee of 16 dollars) We only charge him for the net difference so if his system is covering this usage these numbers don’t come into play, especially because he’s using a battery. If he didn’t have a battery then we give him back the value of the timeframe in which he generated , so let’s say off peak is 47 cents he gets that back towards his electric bill

If you're considering going electric for your heating, you should check out heat pumps!

i heard heat pump heating is not the best, unless it's infloor heating. hot air tends to rise and our body part most sensitive to cold is the feet. I used a mini split unit as a heat pump and it wasnt really effective even though in warmer climates it can be a viable and much more efficient option if you have heating on all the time. For me heating was only necessary when the outside temps go below 5°C, and at that point heat pumps cant really pump much heat.

[@S0me1weird]

I came here looking for this comment. A 55MW/y consumption is insane, even with an electric car. Those houses must be leaking heat like crazy. Like.. are they even insulated? I own a house made in the 60's near the arctic circle and we use something like 15-20MW/y. And its an entirely electricly heated house at that. It's a single, wooden, 2 story house. And I think the insulatio needs re-doing because it's slightly cold in the winter, so I'm spending a lot to make up for lost heat.

[@joshua_lee732]

Due to the stick built nature American homes do leak, but the big killer is the HVAC systems. Heat pumps are rare and most heat is deployed using old school electric heaters and unlike many EUnhomes we use Air Conditioning systems. Many homes here are open concept design too, so we really are managing heat/cooling for a small warehouse and not a home. Plus we have a preference for tank water heaters that are usually electric, same with electric stoves/ovens.

[@JesperVad]

Just looked at my utilities web page: 2022 = 603 kwh. I'm doing a renovation and that's going to reduce will consumption. Heating comes from district heating (CHP)

[@Shumitu]

@@HermanWillems it all depends, as an example I can mention my case, not so big house in central Poland, heated / cooled using AC, all appliances are electric and water is also heated via tankless water heaters. Our usage from 28.03 to 26.05 was 1373kWh so 686kWh per month. This high usage is mostly caused by tankless water heaters which is using 3x230V phases so it can consume up to 13kW every second, so long showers can get expensive :D. In winter usage of electricity is a lot higher as heating with AC (and not separate heat pump) can get more expensive when its cold outside, especially when it gets colder than -10 celsius.

[@RCPhysics]

Pro tip: Since you already have a gas furnace, you can replace your existing air conditioner with a heat pump creating a hybrid system. This will let you use your heat pump for heat in the spring, fall, and most of the winter and only use the gas furnace on the coldest winter days. This can dramatically reduce your total heating costs, especially since many modern run-of-the-mill heat pumps can operate efficiently with outdoor temperatures down to ~30 degF (or lower) so you would rarely need to use your gas furnace for back-up heat. The more sophisticated systems, like geothermal heat pumps and high-pressure heat pumps with variable compressors, may never need the gas furnace at all. Our A/C unit died in June of 2022. Since we had to buy a new unit anyway, I talked my wife into spending ~$2k more for a heat pump instead of a conventional A/C unit. Ordinarily the payback period for this type of upgrade would be ~5 years, but I've calculated our system should pay for itself in just over 2 years because of the crazy increases in natural gas prices recently.

[@unlucky5442]

I second this, I live in Norway and winters can be pretty cold. Since getting a heatpump it has reduced my electricity bill by a surprising amount, instead of just using normal heaters all throughout the house. Also supplementing a bit on extremely cold days with burning wood in the fireplace.

[@barnyardian22]

You said your AC died then you bought a heat pump. Does a heat pump provide cold air too?

[@unlucky5442]

@@barnyardian22 yes, afaik it basically just runs in reverse and provides cool air as well

[@RCPhysics]

@@barnyardian22 Yup. A heat pump is just an air conditioner that can also "run in reverse". Instead of being limited to just pumping heat out of a building, they can reverse the flow of their refrigerant to pump heat INTO a building. The really cool thing is since they are collecting heat from the outside air instead of converting electrical power into heat (like resistance space heaters), they can deliver ~3 Watts of heat for every Watt of power consumed. So, a heat pump consuming 2kW of electricity will be collecting and moving ~6kW of heat energy from the outdoors into a home/structure. This it's one of the main reasons electric cars are starting to switch to heat pumps for their heating and air conditioning. They are much more efficient at heating in the winter time than conventional strip-heaters.

My family got a Tesla roof last year (install finished December 2022) along with the Power Walls, set up in Connecticut, and I can say for sure the chunks of snow sliding off the roof is wild the first time you notice it. We got it because we needed a new roof anyway just due to age and normal wear and tear, so the solar roof just made sense for us. One thing Marques didn't mention is that some power companies will pay *you* to take your roof's generating capacity during peak usage, so you can end up with the power company paying you some months. The power company will take our roof's power during peak hours (most notably during the summer when everyone gets home and kicks on AC) and we'll run off our battery walls in the meantime, and get a credit for it, along with all the net negative we sell back to them besides.

In Australia, they did a big push for solar, stating how well the feed in tariff is. Something around $.60 AUD per kWh. Now that's between 0 and $0.10 per kWh, with those who got the premium rate only keeping that till 2024-2028. Unfortunately it is not fesible for many to run solar, without a battery now, as the feed in tariff barely covers the daily supply fee and other rates. You blow through your "credit" at night and then some. We also have cases where during install they fail to reconfigure your meter for a long long time. So if you spin your meter backwards, the power company ignores your reading and charges you an "estimate", and when you approach them about it they will also fine you Gone are the days of people claiming $0 energy bills or credit, instead it's "solar saved me this much" Oh and if you are unfortunate enough to live somewhere where the "grid cannot support your input" then they also limit how much you are allowed to feed in.

He forgot two major things 1. Your dépendant on the power company to pay u That ended not well in Europe Everybody got screwed. Companies dropped the price they paid. 2. EV is clean if u ignore the slave children who mine cobalt Or the massif and ecological cost of mining But we r destroying Africa so nobody cares Especially not the guy from South Africa

[@ediekimo9110]

So true,..... Very well balanced presentation

[@psycho6020]

I don't normally leave comments but this is by far one of the simplest and most informative videos I have ever seen. Marques is a great and clear speaker and love the fact he doesn't repeat himself so well done now Im off to check out more of his videos

It's also not how solar panels work either. You can't just power your house from the sun without a medium. if the power grid goes down and you have solar panels, your house has no power as well. If you had a medium like batteries then it would draw from the battery. It's designed like this so you don't have fluctuating power in case a cloud pops over your roof and ruins your appliances.

[@offroadr]

​@@ak15567, That is actually incorrect. I can draw direct from my panels. Or not draw, the energy is there, yes batteries make the system more smooth and reliable and it is not wise to draw direct from panels, but it is possible. You just need some different equipment. I kind of want it anyway, because during peek sun, sometimes I trip my intake breaker. Fluctuating power can cause two issues, brownouts or whiteouts. Brownouts tend to cause data loss, but are not usually harmful, whiteouts, can burn out equipment. We have a line conditioner which helps prevent both. In the fluctuation conditions and no battery though, really you can only clean off the peeks, effectively limiting the flow of power.

[@ak15567]

@@offroadr Are you talking physically capable or are you talking NECA codes? It is not per code to have your solar panel DIRECTLY power your appliance. There is no discussion, unless you rewrote the code in the last 5 months since I've checked.

[@offroadr]

@@ak15567, Physically capable, however, just because there is no battery doesn't mean there shouldn't be something in between.

Dude your videos are so well-structured, so eloquent, always filmed so well. I have been watching your videos for years now and I’m sure I will for as long as you do it. You’re just amazing at it bro 😂

I'm totally baffled by these numbers. My yearly usage is 2900 kilowatt hours with a 3 person family, in a connected home (but not an appartment). Those HVAC systems must be freaking monsters.

[@joshualucas1821]

Marques' power use is indeed ridonculous but yours is also quite a bit lower than the US average of 10,000 kWh/year.

[@hotdognl70]

Good job, sounds prety low to me compared to my former situation in a moderate European climate. Out pre-solar, gas fueled household used slightly more for 2 persons. Now we have a roof full with panels, heathpump but no battery or EV. Our production is just over 6000 kWh a year and roughly net-zero. The numbers are high and personaly I think we have some serious chalenges if every home is going full electric even without that monster AC and EV.

His Power consumtion per month is higher than the average german household‘s per year.

This was a very informative video. especially for a guy like me that goes to Africa every year and dealing with power outages whiles down there.

I own a solar sales company, and have sold solar for 6 years. It’s really cool seeing someone experience it for the first time and seeing their experience.

R u guys cheaper than Tesla?

[@Artimidorus]

@@justluxtalks They probably actually will fulfill your order and NOT screw you over, so there is that. Don't base your thoughts on what Tesla offers because an extremely famous KZbinr who is well known to speak highly of Musk and Tesla got this. Look instead at all of the reports of Tesla failing, hardware failing, not installing things properly, not getting proper approvals from the city, and paying exponentially more than what was quoted.

You should tell how expensive Tesla solar roof is compare to the most popularizes ones.
