[@johnwang9914]

With hot pavement, you'll need a lot more than six inches clearance. In Texas, a parked sedan would not be able to keep up with the AC but a parked pickup truck would and that's due to the clearance over the hot pavement. Those panels on the road, six inches or not would be hot enough to fry eggs on.

[@nmosfet5797]

Excellent video! But it just kills me that this would be so easy to do with existing electronics already in the car, if only the EV manufacturers would provide a DC input for the solar panels, without having to resort to external batteries and inverters. This setup has so many voltage conversions: 1) step-down from PV to battery, 2) step-up from battery to intermediate 120V DC voltage, 3) invert from 120V DC to 120V AC for the car AC input. Feed AC to car, 4) rectify from AC to DC in the car and 5) step up to the EV battery's DC voltage. All this could be done with a single DC to DC conversion from PV to the EV battery if you could just get the DC voltage from the PV directly to the intermediate DC bus inside the EV's AC charger. From there on, it's just software to set the operating point of the step-up circuit.

[@Infinion]

The RealSolarCars YT channel has a custom board that does exactly this. I believe the current iteration is for 72cell solar panels, manages 300W charging up to 400V, CAN interface contactor outputs with coil economizers, lots of additional features that might be desired for a DC-DC SEV.

[@zaneenaz4962]

Totally agree !! Just make it easier for people with PV at home would be a big start. Wil Prowse showed how he charges his Tesla from home PV. This case shows roughly 1kW Solar PV, so roughly 4 kWhr per day, or 16 additional miles. Being able to quickly add 5x or 10x that PV to your EV would be super cool.

This setup belongs into a trailer, this way you can leave it charging at your camp site while you have full use of the car. You would add other amenities to the trailer too, and it could become a great product to build and rent out to the world...

[@knuthf]

Correct and the solar panels should be placed on the roof of the car so it charge while you work. The rest of the fancy setup can be bought as a 4.8KWh battery with inverted to deliver 110/240 VAC - to charge the car. They are included in the batteries with solar panels. 5KWh is what regular driving needs every day - 7KWh is 30 miles/ 50 km of driving. A camper towing a 5 KWH battery with solar panels has enough electricity to power a freeze and induction oven - no need for propane.

[@usertogo]

@@knuthf sure if you can integrate it so it doesn't cost anything additional drag. Otherwise have a utility trailer outdoor kitchen, refrigerator with foldable solar covered shade roof, battery and charger, and you can bug out much more conveniently when the time comes!

You can charge multiple devices at the same time. The compass is a nice added bonus. I appreciate how quickly this arrived. I am curious to see how long these take to charge in the sun.

No it doesn't workout 1.2kw of solar would ideally be about 6kwh a day (for solar you calculate on 5 hours per day) but they aren't angled in the correct direction so that won't even happen but assuming you do get that 6kwh with out the other losses in the system on a stock vehicle weight and best efficiency it would add 30 miles per day but the truth is rarely to people get the upto max range numbers to start with, then you have added about 10% increase in the cars weight and as i said the panels face the wrong direction which hoping it is clear around the car the ground being the worst location to have solar they face straight up so only make peak power for a few hour during the middle of the day and finally every step of the system has losses so power is lost in the charger, in the charging of the batteries and again in the discharging and in the inverter and finally in the cars charger and it's batteries an honest figure he would be lucky to get 4kwh of usable power a better idea would be to put all that on his garage double the solar and a few extra batteries and plug into that every afternoon

In many jurisdictions, it is illegal to block the view of the rear license plate like that. People have been ticketed for having bicycle carriers on the back like than. You need to have a license plate holder on the back of that contraption or mount your plate higher. Personally, I think they should put RFID tags in the license renewal stickers similar to the toll tags and have the police equipped with long range readers as well as have such readers on publicly available dash cams maybe even on mobile phones, hence obfuscating the need for license plates to be visible.

[@johnwang9914]

@@michaellim4165 That's the thing, if it was just a machine readable RFID tag such as with a toll tag, a few strategically placed readers such as at intersections would be enough to identify the vehicle and their travel from just a witnesses report of where, when and just a vague description of the vehicle. It would be far more effective for the situation you are concerned about than requiring a witness to remember a license plate number. The logs of the readers would of course need to be encrypted and any access to them logged as to why they are being purviewed for anything other than general traffic information. Many of the tag readers might already exist as cities such as Houston placed such readers a long time ago just to monitor their own bus movements and traffic on major roads long before cities just bought traffic data from Google. Also the Apple Bluetooth tracker already shows that by just having all iPhones periodically scan for any nearby trackers and report any hits to Apple's server with the GPS location of the phone at the time was sufficient to track the tracking device. It isn't necessarily the witness that can read the RFID but any of the numerous devices the vehicle would pass to do so, all the witness would need to do is report the act they witnessed, access to the logs gathered from traffic lights, street lights, dash cams and mobile phones in the area would do the rest and much of this we already have. We already do this to a small extent with police canvassing the area for dash cam, doorbell, and security camera footage in the area.

Great video. While this project was an amazing example of making a portable mobile solar charger, a similar fixed-base home setup solar could be just as effective, and likely see more usage. While Renogy 100W are very portable, but come at higher cost/kWh vs. larger fix mount panels. (some great deals on 1/2 life used solar panels can be found) Perhaps a trailer installation that could double as camper would offer mobile portability without concerns of panels being run over? A trailer might also offer larger surface area, and could continue to harvest energy, even if not attached to an EV. Guess it depend on needs and wants. Still a great demonstration.

Sure, it is free and if you are parked somewhere it can augment your charge, but at 5 miles per hour of charge, I am not seeing this as effective. I mean, if you drive less than 40 miles and can park it for 8 hours, you can recover your charge. Not sure where you would be able to do that. Where I live, you can't block the sidewalk. I could not use it at home or work. If you totally ran out of charge, you could go 5 miles more after one hour of charging. Is that really worth the investment?

[@juangoyeneche7304]

@@JohnnyHughes1 it's a proof of concept and it was improved already. I bet with some extra work out will improve and this can allow you to drive to remote camping areas where you can spend a couple days and have a good charger and when done with camping you can drive back. Maybe small trailer connected to car and 3 to 4 of this set up and at this rate you'll have 20 miles per hour.

[@JohnnyHughes1]

I am certainly not saying adding more solar panels would not work.. They could. If you also had an RV and triple the input to the battery and max out the inverter, where you could charge at 20 or so amps, it could be a good. We are just not close to the total power needed without about 3x (at a minimum) the input power.

[@jasondong9721]

Great concept for the future when battery tech and solar panels improve

[@marksilvestro450]

We will have moved on to hydrogen fuel cells by then...

I don't know what people are expecting from solar cells, really, but it sounds like they will be disappointed. :)

[@pip5461]

Surely the battery is unnecessary, you've got the car batteries which are sufficient... The wind drag caused by the solar panels won't be helping much. You've got more money than sense... :)

[@gridfreeordie]

This new 48V EG4 inverter is a rare unit that can actually run off of solar input only; but almost all other off-grid inverters require a DC battery or AC input connected. The vehicle battery is ~400V so it cannot be used by the 48V inverter. Furthermore, with only solar connected you'll need to exactly match or oversupply the inverter in order to supply a continuous AC load...which means you'll either always throw away solar input power or frequently shut down the inverter when a cloud passes over or the sun angle changes.

[@pip5461]

@@gridfreeordie thanks for the information...!

[@SuperVstech]

I agree, the wind resistance will lower his range significantly… he would be better off keeping the panels flexible, and storing them in the car. Or building a roof rack system that keeps everything horizontal…

[@danielderkacs6180]

I've not recorded any appreciable difference in W/mi since installation on Teslafi.

[@SuperVstech]

@@danielderkacs6180 odd. Unless you never drive highway, I would expect a 20% drop in range…

[@roundgarage]

Brilliant job sir. If you unraveled the pv panels the other way over the car roof and hood, it would not be a problem having someone drive over them, Thank you.

[@PaulsGearReview]

that'll get stolen real quick 🤣

[@howardfox6660]

I get it. Great idea,just drag the panels while you drive. How smart.

[@PopsGG]

Loss in range due to weight and drag will do more harm than the charging does good. Unless you only drive the car 2 times a week and it is in the sun the rest of the time. Could be good for a camping trip though.

[@ajuber876]

While not perfect... it's perfect!

[@Davesivak]

Just doesn’t make sense

[@jamiehalifax4954]

No.. it saves dollars 🤣🤣🤣🤣

[@lawnmowerdude]

This is so cool. I would love to see this as an optional accessory for any electric car you could buy. Or maybe even a solar powered car cover.

[@safeandeffectivelol]

You get 5 miles per hour of charge

[@jamesmarinelli2177]

Im trying to do something similar with 4 pipes at each corner of car then cross pipes. On top of this scafolding will be large panels this way its a sort of pergola over the car all interlocking with locks so no one an easily steal the equipment. This way it acts as a shade over the car , it should cause interior of car to be much cooler and also protects paint cause all my cars after few years paint starts to fade which is expensive to repaint. Also I would be able to set this up at my work parking lot with equipment being out of way for every car passing by. MY Model Y will be sitting in parking lot all day under hot sun so might as well soak up energy! This setup of yours is awesome !

[@belgarion0013]

Impressive work and god video! Maby in the future, more flexible solarpanels that can fit in the trunk would be even greater.. Have a nice sunday!

[@richardjohnston9899]

Good job, I been trippin off how to create 5.9 kwh for a mobile situation. Good to see smaller versions being effective

[@kpboix99]

Thats an awesome portable setup! Good to see that something like this can be done with a Tesla.

[@lehsu]

Consider some wheels under the panels. This would help folding and unfolding, in addition to not have the panels sitting on possible hot floor.

[@rjlinnovations1516]

Excellent ideas portable charger. Thank you for sharing your video. Watching and and I’m fully supported from Canada 🇨🇦

[@james10739]

They should make an option that would let you use solar directly I mean if i assume the charger is basically a switch mode power supply so it's just turning ac into DC so if you are around 140v, 150v it should work fine

[@RakeshKumar-lb8cw]

flexible Solar pannels are good for this type less weight easy to carry

[@nwavette]

This is awesome! I would love to have something like this on one of the all electric Jeeps or a Rivian and have a much more resilient adventure vehicle.

[@danielkim7841]

1) you look crazy pulling out those solar powers, but u r a genius 2) the neighbors are staring at you and whispering behind your back, but u r a genius 3) no one has ever has deployed solar panels in the history of KZbin to charge their tesla, but again, u r a genius. It's a high price of having intelligence!

[@chrismerten2101]

add two garage door casters for the center section so it folds out smoother, maybe 20 ounces added weight with huge convenance

[@mordanistl9869]

A thought. Put it all on a trailer obviously smallest lightest then you can put all control equipment in there while being able too disconnect it all if going on a nite on the town , but conceptually awesome gives me many ideas

[@sulu1men]

Lot of effort, appreciated, your not regular ev owner 👍

[@johnwang5336]

I must say it's very clever indeed. If you're gonna do it in your driveway, put them on the roof, if used on the road, that depends how long it takes.. it's kinda drag since super changing stations are everywhere and affordable, so..

[@appudipu]

Intelligent product.. superb..just fall in love with it .

[@InteloPL]

It si well done, got to give you that. My issue is that the tesla is now basically the transportation device for it's own power source.

[@louren1951]

Nice job, I wish I was smart enough to build like that.

[@suburbandreams842]

Great video, good design, and thanks for sharing this. I hope solar cells could be more efficient in the future.----2022 Model Y Performance owner.

[@VGAplayer]

the Tesla need this fix on the roof 😎👍 nice video thx

[@slijkhuis]

I love the ‘because I can’ attitude, however it would never be used efficiently. The extra weight, drag would be killing, the noise and heat will be annoying. You basically lose your trunk. Plus the charge speed is absolutely tiny. Lastly, you need a huge parking spot and hope to god that nobody likes to tramp on the PV panels for fun. Again, love the passion to do something cool, however extremely (that is an understatement) unefficient.

[@lukeycherrett7372]

Have thought about small trailer. You could house everything inside freeing up your boot. And you don't have to always carry them with you. Only on long journeys. Loving your work keep it up. 👍

[@Robby368]

I really like how it blocks 100% of the brake lights

[@rodrigo_888]

I can't believe I watched it to the end.

[@yggdrasil9039]

This is awesome. Great job, I wonder if v3 or later might allow you to stow panels inside the car, pull out, rotate 90 degrees, and then unfold, on some kind of extendable rail.

[@RedspawnSilver]

Put some small rollers on the end of each link off center from each other and it’ll make it easier for you for the “roll out”.

Nice work! I'm building something similar for a DIY EV, only difference being I'm setting up the circuit so I'll be able to charge while on the road.

[@Mike-.]

This is so cool but insane!...but awesome!

[@JohnSnow-lb6xi]

Amazing.... you should add some expandable legs on all 4 corners that raise the panels up and then you can back the car under it.

[@justanother240]

Nice setup! I would be concerned about the longevity of flexible panels. They don't seem to last much longer than 1-2 years compared to their rigid counterparts that will easily last 5-15 years.
