I like your video @jerryrigeverything
I know this isn't very efficient, but it's still interesting to watch.
Can you do this over the course of 8 full hours to see??? In full sunlight
its not a solar roof unless its providing passthrough charging while teh vehicle is in operation. (as in your CAR battery drains slower) and actually charges while parked, and at a rate that doesnt drain your small, what looks like a solar generator similar to the jackery 1500, with very small capacity and a max of 400w charging speed. just because you put a couple semi flexible solar panels over your car doesnt mean its an actual solar roof. its just a spot you chose to place your panels, instead of on the ground. and the solar generator even with 400w of passthrough charging on top of the capacity of a fully charged solar generator, you are going to not get a whole lot in return. you want an EV thats actually solar powered? its only got a max range of about 70km at full charge (when new), and is only available in matt black due to how solar panels actually works with the placement of the Sono Sion. but its purpose built to be able to be fully charged from 20% in 2 days without use of any external power. (but has the option if you need to go further than the default range and cant wait for the sun) "fully charged" did a nice little cover of the prototype's performance functino. ua-cam.com/video/U5LKU6bWScc/v-deo.html
Sir, why don't you park it in a sensible place, like away from the tree's.
Great little video though 😉👍
I told you why.
So 700 watt on the model 3 would give you up to 5,000 miles a year. Which is only $250 a year worth of electricity. It’s just not economical to use solar.
All I can think about is how useful this would be in the apocalypse.
preferably just use a gas car is the apocalypse lmao. Teslas are fast, and quiet, so you can go somewhere really quickly without making any noise. However, being able to just dump gasoline into a car and being able to go is much more efficient
@@ifthesewallscouldtalktheyp7692 gasoline has a short shelf life, it would only be viable for a few months then you’re on your own. While yes pumping in some gas and zipping off is quicker, than having to wait for a charge. I think someone would be able to rig it so the tesla continuously charges from the panels while driving.
Could create pure ethanol if you have to park and charge best belive the marauders will be on yoi
@@ifthesewallscouldtalktheyp7692 gas goes bad after 6 months so if the apocalypse happened no one would have any gas and refinement is complicated
You could put a propane generator in it. Propane shelf life is amazing. I'm not sure if it's more difficult to refine than diesel though.
Stripout all non essential weight and seal a compartment off with 2000w generator and a forklift propane tank.
For people like me who go to work and park in open parking for 9 hours every day it makes sense
Yes! Exactly. I'm one of them.
*Great **Generater.Systems** so far. We have the same brand just a little less power. This one is so much quieter then our first one. Great buy*
It helps in emergency situations
Not really, but good try
Tesla can make this better if they did panel roof hood and rear door should be an option
It does not help a Bit
Look at the amount of Gear he has just to be able to do 5 miles,😳🤷 walking is way faster than waiting for this to charge 🤦
.
If he Removed all this Dead Weight he would probably gain way more than 5 miles range plus he Would save loads of money also 🤔🤨
When they combined the solar energy to a calculator. Nobody bought batteries for calculator anymore... Someday the car will be solar. Or the government will make a law and force you to pay for energy, or make it impossible for you to modify. Its not about making it easier for you. Its absolutely about money in the pockets of the game changers.
they need a "production model" class in that solar race across Australia!
That would be cool
As you say, for camping this is a damn good solution
No, it is not great, because the panels are about 300Watts with the losses in the cables. The car uses about 300W so it is a net 0. But then you also have losses in the cable to the car so you get less than 0, you are at negative. If he let the car sit for another hour "charging" he would loose those miles. You can clearly see that as soon as the 2kWh stored from the battery are down the car is at +0miles. At 7:35. So the only way to do this is to have 2kWh power banks and add a couple of miles, then try and charge the power bank with the solars and repeat, not worth it. Plus, you can't do that if the panels are fixed to the car and not to mention the fact that fixed panels on the car will yield very bad results.
This is why solar panels on a car don't make any sense and anyone who tells you otherwise is lying to you.
The only place this could work a little more is in a Van where you have the top AND the sides paneled up.
@@teslakiller6959 You are so wrong Ioniq 5 has solar roof if made properly any solar tech will supplement any electric vehicle
@@teslakiller6959 you are totally wrong a solar panel will benefit evs so much all ev manufacters have to do is create a system to balance it
Great test. I think a lot of people think a solar Tesla roof panel can fully charge the batteries in a few hours. This is a great expermaniment. Thanks for making this video. Id love to see a solar roof tesla just to maintain the battery while it sits in a hot parking lot all day.
I would have thought you could do a few miles worth in a day, but 100 kilowatt hours is a lot to add from a roof. More like 300 hours straight of hot sun. But hey, you could help out a stranded car with them if they need to get a few miles.
the added weight and cost to keep the battery topped off probably not a net win except in very special situations like camping at the beach for days. for those cases you can bring yer own!
I mean 30 panels usually can get most houses and families of 4 off the grid. So to think 4-5 panel’s on the roof couldn’t charge (4) batteries would be silly. It probably could get you at least 200 miles trip from it if I had to guess. It also would depend on how much sun you’re getting daily though. Is it worth the $2000 you’re going to spend to install the rack and pv panels electric hook up for backup battery pack. Also the cost of the car won’t hold value it’s overpriced. In 5-7 years teslas will be worth a fraction of the cost once they realize nobody is buying them anymore at their high listing price they’ll fall. I switched to no car and saved a lot more. ❤
I've done similar testing with a Goal Zero Yeti 1000, and I figure with maxed out solar input of 800W (net 650W), I could get roughly 9 miles per day for my i3 when real solar exposure is figured in for my location. Obviously, more in the summer, and less in the winter, but in a pinch when the world ends and people are resorting to using leaves as toilet paper, I will still be able to go buy beer. /s
lol
You still utilizing your solar setup?
@@supjay3945 I've not had a practical use for it. My efforts were exploratory for camping, but I haven't really needed it.
until you bend a rim or pop a capacitor on the computer unit behind the dash
In an apocalypse, I won't be using leaves, but a portable squeeze bidet like I'm already doing at home. No leaves and no toilet paper. .
If you're going to pack that as a backup...an expandable aluminum panel mount would be lightweight and you'd have more control over panel angle/directionality.
These panels already have built-in kickstands and can be aimed towards the sun, just not while sitting on top of the Tesla. The nice thing about having the solar generation separate from the car is that you can park the car in the shade and still have panels in the sun.
@@TheTechofTech Im not super into cars, whats is the benefit of parking your car in the shade?
@@ifthesewallscouldtalktheyp7692 so it doesn’t heat up the inside so when you go in it won’t feel like a furnance
@@ifthesewallscouldtalktheyp7692 I don't think you have to be into cars to know that they heat up like a bitch.
Great informative video. I’ve been exploring these solar options as I wait for my Cybertruck. I’m considering converting a 5x8 trailer to a solar support/charging/mobile base camp thing.
The challenge will be generating more power from solar than you lose from drag while driving.
@@TheTechofTech agreed and that is the challenge we need to overcome. Maybe someday when panels are more efficient. For now I’d like to at least be able to replace some energy and be relatively self sufficient.
That would be so Kool. Keep us updated ⚡🇺🇲
If you drive a Model 3 efficiently, you'll use about 250 Wh per mile. With this 360W-rated setup, you got about 250W of real-world output, so that's about a mile of range per hour of charge.
You can do a 2000w set-up in the Cybertruck ⚡
you're badass bro
I really wish Tesla could provide an low voltage DC input for charging the battery slowly.
That's not how the batteries work
@@Pinkielover I think you don't know how electricity works 😬 There are DC to DC voltage converters can be used to allow changing with a low DC input.
@@FuyangLiu you should be more specific. Also consider the heat generated
You could for the 12v battery but wouldn't be able to charge the car itself unless you had a high voltage 450v array and charge controller.
Nice. I am thinking of getting it instead of a charging Station. I only drive around about once or twice a week. And a charging station would be more expensive. Is the solar waterproof?
Very fascinating video. I'm looking to doing the same experiment but with a plug-in hybrid. If you do the math the plug-in hybrid battery is a lot smaller comparison to a Tesla battery. That would mean that the efficiency for the amount of charge from the external battery that's the blue Eddie's would work even better. I'm taking notes thank you for presenting this.
This made my day.
it takes a AAA about 1-2 hours to send a tow truck in Dallas. The solar roof gives you 7 miles in one hour. So it a good idea to me. To get even more miles, add the solar panels to the hood and truck. I know this might sound weird but I see people place graphics on their car's hood all the time, make it a transparent American Flag.
It’s not 7 miles in one hour from the roof. It’s 7 miles from the external power bank. It was 1 mile per hour from the panels but that could perhaps be 1.5 direct into the car battery if that was possible.
He just wants the new ioniq 5 but has no time to wait and went for it 🔝🔝🔝🔝🔝
Not a fan of the exterior styling, but that interior is 🔥!
There are some cars with solar panels coming in Europe. The German/Swedish Sono Sion and the Dutch Lightyear One.
And the Aptera Paradigm which is by far the most energy efficient of the 3.
The ionic 5 and the cybertruck will have a solar roof too
@@Random9rA9 But not as energy efficient.
@@danylbekhoucha6180 yes that's true
Being a fan of Solar Team Eindhoven, I'm rooting for the Lightyear One.
Simple solution would be to connect the solar panels on your roof to the 12v battery system in your electric car through a small lightweight solar charger, that way it can charge while driving and things like power steering, brake booster, electric windows, radio and screen that most likely run off the low voltage 12v battery and not the high voltage pack, will be continuously fed by solar power. Then you can set it that when your 12v battery drops below a certain voltage, your high voltage pack takes over and through the DC to DC charger tops up the 12v battery when the solar can't. This should add range. To charge the high voltage pack directly from solar / inverter or mains, the car has to be off and stationary.
Amazing for anybody wanting to camp long-term, or travel anywhere in the world, also very affordable. Not practical for everyday use to charge your EV.
I searched for this
This would be great for everyone in California!
No, it is not great, because the panels are about 300Watts with the losses in the cables. The car uses about 300W so it is a net 0.

Will keep your car cool. Tesla should do your set up.
Lol. This feels like the EV equivalent of carrying a Jerry can.
A $2,000 Jerry can though haha
@@rickmaff lol honestly.
@Shawn Huffman I rarely turn down anyone offering me a pint! lol
wouldnt it be cheaper to carry a gas powered generator
240Вт в час, при батарее 80кВт (грубо). И того за день это всё хозяйство зарядит в лучшем случае 2кВт, а полный заряд более чем 40 дней, и это если будет солнце. Видео интересное, но увы смысла мало, потому то панели на авто и не ставят, это не эффективно, не выгодно и не окупятся панели на крыше, ну или очень долго.
Hoping Tesla can integrate this with Cybertruck bed cover.
With larger panels and better efficiency, we could get practical free electricity

Thank you for making this video so all the idiots who think this is a good idea can understand the real world cost/benefit. As an engineer specializing in solar and batteries, this is a never ending battle to help people understand. People think they will charge their car in usable form. Imagine sitting in the sun on a hot day, you’ll probably use up all the charging energy just on running the AC.
+1 sub from me.
I just put a wind turbine on my Tesla and I can drive all day. Of course that’s because I stopped to supercharge.
Yes. People underestimate how much power it takes to move a car and overestimate how much power you can generate from solar. A solar roof on a Tesla is an idea borne from the intersection between the two.
Ecospider5's idea of the wind turbine perpetual motion machine also keeps coming up. "Why doesn't a Tesla use regen all the time to top off the battery?" Same thing in the world of ebikes where someone actually made a trailer to pull behind an ebike to charge the ebike's battery. Never heard back from them after they had a chance to try it out. lol
@@TheTechofTech Exactly.
I also like the one where people say there should be solar panels at every supercharger station. The amount of panels needed equal the capacity for a single supercharger (72-250 kW) is like a field, let alone up to 40 or 50 SCs. I’m not saying don’t install solar but just realize the scale we’re talking about.
Yes! I see that often, as well, especially since *some* solar is installed at a very small number of Superchargers, though none of it is anywhere near enough to supply even one Supercharger for the day.
What if the panels were mounted on a roof rack like a giant wing, with enough clearance to provide shade? I wonder if you would want downforce or lift considering how heavy the car is :p
I'm only somewhat kidding. There's a guy who added a solar panel to the roof rack of his nissan leaf, which apparently gets him an additional 20 miles per day when combined with the solar cells he's already glued to the top of his hood. It's silly, but if it works...
This is just stupid. In arizona on the best day, you will get 1kWh per m2 per day, so a total of 2kWh per day. Maybe a little more. So you can drive for 6 minutes after a day of charging. Totally useless. If you need a "Get me to a charging station", It would be easier to have a backup battery in the trunk. And then just place panels on your house
25W to 250W of input. That's not enough to run the AC of the car
AC is expensive in power.
Joe Rogan asked Elon Musk if he was going to put solar panels in the roof of a car to help in battery charge and mileage Elon said he thought about it t but it wouldn't have been very cost-effective.
Yep. It keeps coming up as a request, regardless, and I finally had the means to show the challenges using this particular setup.
@@TheTechofTech Elon Musk is Elon Musk for a reason. As you clearly proved, solar panels on a car are useless. The only energy that came into the car was from the stored kWh in the battery.
Actually, about 250Wh on top of the battery was provided by the power generated by the solar panels during the time the charging session was active.
@@TheTechofTech which proofs my comment even further. 250/300W is what the car uses while idling while charging, you can check it with an OBD Adapter cable. This is why when the generator was depleted the charge dropped to 0km. If you let it "charge", ie the car on, while the solars were on and generator depleted, you would actually loose charge after 10 hours. Check it out and you will see - change to km and measure before and after.
A fold out solution is the way to go if you want to take solar seriously for car charging. Look at how they roll up solar for the ISS, you want something like that where when the car is in motion you roll them up then when you want to charge go roll them out into the surface area of like 20-40 Teslas
I simply put an 8.4 kW array on my roof and charge during the day. of course I am retired so I am home all day typically. I don't have to worry about putting in on and off and I have a battery for the house so even if the grid is down I can still recharge. At the same time when I don't need to recharge I can support my house loads and feed power back to the grid to get some money back.
You're going to fry your EV's onboard charger by using that high frequency, transformerless inverter. High frequency inverters like these provide no galvanic isolation between the inverter's DC boost stage and its AC output which can allow high amperage DC current to pass through to your EV's onboard charger and severely damage it or even set it on fire.
You are smarter then them at the Factory, why is the vehicle not built with the hood, trunk hood and even the upper doors and fenders not solar panels?
Multi junction solar cells will be efficient and cheap enough in 10-20 years they will be on the skin of many EV's in the future I think (hope). They are already reaching numbers at 40% efficient.
Is it technically possible to run DC-DC? I assume Tesla is limiting it to only accept superchargers :/
The issue is that the DC input for Teslas is geared towards a heck of a lot more volts as well as amps. It would be possible, sure, but maybe not efficient using the exact same DC input as Supercharging.
We own that same BLUETTI Power Station, and just bought eight 300W Flexible Solar Panels (2400W). This is one of things we want to attempt with our TESLA M3LR…
🤔
Put four dynamos on your tires and it will charge your batteries as you're moving remember the dynamos for a bicycle that made the light go brighter those are the ones that need to put on four tires
..a 1 m x 50 m rollout solar would work 20kw/h at peak hours...try adding a portable steam turbine powered with burning woods around site..for emergency test ..
Why not, better then surprotection and kabeldrum rolling for miles.
Nobody Put your Farm an owning Gasstation or Electrocity.

What if you just leave the lights on in your garage and charge all night! Head lights put panels on the wall in front of your car’s headlights! Try high beams! Solar power just add lights! Wind power just add a leaf blower, hydro power supply just pump the water back into the lake!
My problems with Aptera.
1. Cost is too close to Tesla model 3
2. Only a two seater
3. We don’t know how safe the vehicle is, weight is a big factor.
4. Profitability is uncertain.
5. Cash flow burn of $50 million/year.
6. Doesn’t qualify for federal/state Tax rebate incentives.
7. Haven’t herd any updates on private equity fund raising.
8. Best scenario won’t start production till 2025.
9. Tesla is continuing to reduce prices and increase quality.
10. Early production models will have very few features till at least 2027
It is clearly not viable. Just grow the sugar cane/canola, make ethanol/Diesel and burn it in your old ICE vehicle that doesn't cost as much as an EV with a starting price no less than $40,000.00 excluding the solar panels and Bluetti charger which will add to the weight of your already heavy EV.
There’s no need to put panels on the roof. The lawn was sunny and better place with no risk scratching the paint. Also the orange cable wasn’t needed, you could have plugged the dummy straight to the Bluetti
Absolutely brilliant. I can carry a Jackery and solar panel for an ebike. Thank you 🙏
The panels barely made a difference. It was all the Bluetti.
The only use for panels is to slow down vampire drain at least a little bit.
There lies the problem with solar,all made in china,some states get way too many cloudy days and efficiency of panels not very good.Either way I don't have 50k to blow on a ev vehicles and I only buy used anyway.
A solar EV has to be designed from the ground up to run on solar, you cannot just convert an existing EV with solar panels. Because there are energy efficiency issues, like better aerodynamics for the vehicle.
I don’t understand why EVs don’t have solar panels already… even you only net 10% daily usage, it is a waste to forgo that capacity when the car is just sitting out in the sun baking
Since it is not a permanent drivable setup, why not use a rollup flexible 2000 watt array beside the car. Just roll it on the ground and off you go.
Mm?? I believe there may b solar panels dat charges even in shade.. even better, there is 'transparent solar panels ' now. Not sure about efficiency to cost ratio...
Of course, this is all just for entertainment purposes. One doesn't save any more at all driving a Tesla and this setup.
What if the built the roof out of pannels.just to give you enough to get you to the next charging station 🤔
For a few grand. I think I would invest,and charge my car up all the time,and save on electric bills. you would be totally independent to drive across the states, don't have to be afraid to go on those long drives in the middle of nowhere. is that possible?
Seriously... you are charging from a BATTERY!
Your Solar is only
AAA membership gives a certain number of free tows. Don’t make a habit of using tow trucks and it might work out.
Probably best to have a gas vehicle as well. Then you can let the ev charge solarly for a longer period of time.
If you can afford a Tesla, how come you can't afford an Ecoflow? 😉🤷♂️😹
Why electric car manufacturer doesn't make an electric car with solar panels roof? isn't it more efficient?
Makes you wonder if/when Tesla will come up with a way to embed folding solar panels into the car's system. Imagine the equivalent of a "soft top" but it's actually solar panels that come out of trunk and cover the top of the car.
The weight of carrying that battery charger and solar panels is probably inefficient to what you get out if it
So you go to work, 8 hours and get 32 miles worth of juice? Would be enough for me.
In a jear you will get about, 1000 miles of range in a year. And that's not Band.
In this case, I think 7 seats van are better place to put the panels on. It has large space for
but your not charging from solar, your charging from that $4000.00 battery in the invertor
You've souped up the Jackery solar setup from 2020 and I like what I see.
I have a cargo-bike (E-Bike) that I just equipped with a sunroof: 0.5 m² of solar panels with 100W peak power. That is also not about cost efficiency - In the Netherlands, where I live, I need around 8000 hours of sun before break-even. It's just a fun project to see what we can do with solar power and the freedom of not having to hunt for a power socket to charge
Meanwhile in Sicilia with 300+ days of sun every year, no one uses solar
maybe if the solar directly charges the battery, it will greatly minimize energy loss
Directly is generally inefficient too. An MPPT greatly enhances the charge rate in a solar system by balancing the power from the panels to a voltage more apropos of the battery. Same would work here. As long as the BMS can reject that transfer when the battery is full, it'll be just fine
@@standardloginname but it's more inefficient if it's dc to ac to dc again. so much more conversions. but if it's solar panel dc directly to scc of battery than it's much less step. come on, who wouldn't want that?
@@jetfu400 then you are stuck with maximum current from panels being the charge limit. That is often very inefficient. That would also mean you have >300v on the roof which doesn't work within any safety standards. A relatively low voltage array on the roof never exceeding 42v works fine from any safety perspective. If you just make the PV array a reasonable match to the 12v system, increase the 12v system capacity a little and make the HV to 12v interface bidirectional you open up a lot of possibilities. Plenty efficient for PV collection. Plenty safe. Even a small chance of charging a stranded EV with literally anything including jumper cables from any ICE.
@@standardloginname so you're telling me that converting dc to ac first than plugging that to the electric car, then the car converts it again to dc for charging battery is more efficient than direct Solar panel to Charge controller of the battery in the car? come on man.... less conversion is always better and more efficient.
@@jetfu400 I'm not saying that. I'm saying that's a terrible method. Except that every DC to DC convertor does that to some degree. The higher the frequency, the more efficient it is. The example shown in the video is about the least efficient method possible, due to the invertor used emulating a residential power supply.
my suggestion try to get a solar flower. for cars. for example. this product doesn't exist yet.
Nice 👍🏻 thanks for the video. I was always curious why there is not an option for evs yo have solar on top. In scenario when you left a car on a parking spot for a day while working it can add a lot in long run.
With a more efficient DC to DC charging system a 10% improvement should be possible.
Haha that’s a awesome idea. Bluetti is releasing the EP500 soon on Kickstarter that holds 5 times the capacity of the AC200P. This would be a cool video to see too.
It’s 2.5x, which is still significantly large. I hope to get one to feature on the channel, but they’re barely portable.
@@TheTechofTech ah I was thinking of putting two of them in parallel to double the capacity. They are heavy at 145 pounds each though.
When is this coming out?
@@davesmith5260 in a month or two are when the shipments are reaching out.
@@kpboix99 so how much could you charge a Tesla on this?
Tesla should make a charge cable that will charge car to car like siphoning gas.
7 miles is my drive to work….so that would be great.
please cover it permanently and cover all the surfaces minus under.
you can fill the bonnets and locate the car somewhere with a better sun!!!!
bypass diodes... you need them. and each cell should be smaller.
So you have 360 watts of solar panels yet it's drawing 10 amps at 120 volts (1200 watts, just multiply) - this means it will drain the Blueti battery (it's basically a giant battery bank) and then start charging at the 360 Watts or lower value.
You may have to unplug the Tesla to let the Blueti recharge it's internal battery also as it may not output to the Tesla when drained...
It's hard to see, but once the Bluetti AC200P hits zero, it automatically turns off the AC output, so there is no draw from the mobile connector at all.
Is that, "Bonded Plug" you mention the neutral to ground shunt?
Yes.
I wonder if teslas will have a shorter and shorter beater life as time passes
Why do they not have solar roofs on EV cars already. Makes sense!!
It is better to directly get an Aptera that can charge up to 70 km with his solar panels included.
I talk all about the Aptera in this video because I agree.
clickbait You wouldn't go very far even i Az direct sun
Has been in my mind for years, even better when automotive manufacturers can invent attached invisible solar panel onto car's body as a paint layer of the car that would be amazing just like one of the kind rare blue paint of Lexus LC 500
Was done to marina boats not too long ago. Clear coat paint to use solar to use radios etc. Cb radios. Ham radios.
Back then it didn't put out ALOT but technology now so days would allow higher watts / volts.
For the size of the panel, why u only get240w
what about the hood and trunk minus the back glass.
I did the math to estimate how much time it takes for a full charge
Panels are 120 W at peak power, for average power over time take 20% of it (sun is not at the zenith 100% of time, clouds, night, etc), total average power: 3*120*0.2=72 W
(Remember, Tesla superchargers have a power of 250 000 W)
Energy in a model 3 battery: 82 kWh
How many hours it takes for a 72 W power to achieve 82 000 W*hours of energy (with 100% efficiency )? 82000/72=1139 hours.
1139 hours / 24 hours per day = 47 days
Congratulations, you saved the world
But you can fully charge an ebike in one week in summer
You are fudging way too much if you’re just talking about charging with solar. I can get about 90% on a sunny day for many, many hours if I can monitor the position of the panels. That’s one of the points I make against rooftop solar panels on a car, actually. Remember that the purpose of this video was in part to show how inefficient rooftop solar on a car would be. However, for running your needs in a small RV or off-grid cabin, including charging an ebike? This would work pretty well for that.
So a solar panel Tesla literally moves at 1mph
I would like to see this test in a desert. it would be interesting
+1 mile per hour charging. If power is doubled +2 mile per hour charging.
Tesla range is 358 miles. Going 80mph is around 4 hrs to run out of battery. 4 hours of charging is 8miles. 366 miles increase.
In direct sunlight it might be more. I’d carry a foldable grid in the back of my car in case I run out of battery or start a small business if anyone runs out of battery.
I might be wrong
Probably good for powering it (partially) for overheat protection.
Looks ugly.
Yep. If Tesla ever offered factory solar, they’d use panels that were completely black in finish, for sure.
