Thanks! So much more I could go into...and change. Not enough time!

I agree! It’s funny how everyone has something to say but nobody is doing anything to test theories. I love how you just did it, just do it and figured out solutions. I would do it with my model y but I’m waiting on the cybertruck for the trade in. I can’t wait to rip it all apart and throw my system in it just like you did 🎉🤙🏽

@@gridfreeordie PLUG YOUR CAR INTO YOUR BELLY BUTTON AND YOU WILL HAVE POWER FOR LIFE.

I totally agree. DC/DC charging would save about 30 to 40% energy losses from the inverter converting dc to ac.

​@@leviahamefula3994there must be a way to do it, considering that's what the car does at a supercharger

Agreed 100% 🤙🏽

This is not a “solution”. It’s like pulling out a ti-84 to charge your house. What’s the point?

Gracias!

I lost track of the link to an online aerodynamic calculator tool I had sitting in a tab of my browser, but playing with that, to find the sweet spot for re-orienting the angle that stack of panels rides at, and maybe putting it into a smooth shell (made of foam and PMF, perhaps) for travel, might actually improve the aerodynamics.

Its a good proof of concept...i appreciate his efforts.. Putting money where his mouth is..👍

I'm pretty sure that misses the point that this is a destination charging system, not a 'while-driving' system.

better design welcome. mr tesla.

Doubtful there’s any real impact from drag here. Reason being is the entire system is lower than the body of the car. The rear spoiler will also serve to push airflow up and over, etc. it’s also pretty close to the car itself and not much of a gap between the two

I don't think it's just to prove a point though. Seems like this is how he lives his life.

Expect about 85% of room temperature power when facing the sun due to higher temperature.

why don't you get a crybertruck and do this while we watch?

Is the frunk made of metal? Or plastic?

@@bengrillet The "frunk cover" (i.e. the hood) is made of painted metal. It's a fair criticism that the terminals and cabling should be covered with an insulator.

The batteries are encased tightly with styrofoam pads now.

is there a smart solar panel which can follow the sun's angle ?

Why would you just use a much simpler controller/battery that can take in the solar and output to the car and be much smaller?

😂

That’ll be on version 3.1 lol

How about not go through so much hassle and just get a simple gas car 😂 it’s understandable if you are in electrical profession. 😊 no offense I like Teslas

I was thinking the same thing before I read your comment. 😂

@@Dptl I think it’s been covered in these comments and those to earlier videos by this channel, that this is more of a fun project/experiment. Not like were all going to drive around dragging 20 panels… But to your point- i can’t think of much easier than plugging my car in at my house 1-2x per week. I don’t miss seeking out “cheap” gas, smelling gas, pumping gas, huffing fumes etc. Elec on the other hand is everywhere. Lastly if things bad I can’t make gas, but I can make electricity. For me I’ll take the simple old fashioned electric car👌

@@michaelsmithers4900 i appreciate your response. It has been a constant dilemma for me since growing up and learning about the gas scarcity and air pollution concerns, one would think that here we are today in the age of electric cars by these revolutionary auto manufacturers. If the goal was to promote electric cars to eliminate worries of running out of gas then by all means all electric car manufacturers should be controlled by government and they all should be free for whoever wants to buy one. My goto comparison is model 3 and honda civic. One is 60-70k the later is 25-30k. According concerns about end of gas, it is clearly no brainer the electric cars should be abundantly available for free just for the fact that electricity you can generate but the gas you cant (your understanding not mine). Just a healthy discussions. Imho.

Two things: 1) This is basically a prototype, a 'proof of concept', a first or second try out, and pretty impressive for that. 2) If you want to cross a wide area where charge points are few and far between, or non-existant, it would be reassuring to know that you will never be stuck with a dead battery. If you tried the same challenge in an ICE car and ran out of gas, you would be screwed.

@@bengrillet it proves that EVs are not suitable for long distance travel. And there's no way anyone can get the mileage to offset the huge amount of co2 produced making EVs.

At the beginning, it was nothing and God said let be a steam engine , God liked it and then said let be desal engine, God liked it then said let to be a gas engine, God liked it them said let to be EV cars God liked it , I'm really sure God will say let to be EV charged on solar panels one day .

That's already a reality in Aptera and another startup with a "one" in the name which I can not recall..

If you trick the tesla bms you can already do this, hook up panels in series until you have near 400v vmp and the battery will take it. Evtv did this with an 85kwh pack from a model s

@@SolarTechFL can you tell me the title of the video?

I think he’s referring to EVTV Motor Verks. I can’t find the specific video but there’s a good place to start looking for it.

I think 2 panels would keep 12v battery charged and prevent drain from traction battery over long periods.

Because using an unauthorized DC charging unit will almost certainly void the warranty. Tesla could have easily added this feature but it is too risky to cover because who knows what some fool could splice it into. A solar charge controller will overcharge a battery if there is wrong system configuration or wrong wiring.

Converting to AC and back to DC does lose some efficiency, but not too much. Modern inverters like the EG4 are very efficient. You get a lot of safety and battery management courtesy of Tesla by going to AC and back to DC so it's the right move for a simple system like this.

www.amazon.com/dp/B0B8J492BR?psc=1&ref=ppx_yo2ov_dt_b_product_details Or you can make your own with a little math. The 10deg ring spacings are fairly linear for small angles but widens to infinity if you want to capture very wide angles. (ring_radius) = (height_of_dot) * tan (sun_angle), where a sun_angle of 0 is when the sun is directly overhead

Actually the bypass diode on each panel prevents any one panel from limiting the current of all the others. If one panel is lower current, at worst you'll get the current/power equal to all the other fully illuminated panels, and in reality you'll get a bit more power due to a boost in the arrays fill factor. But overall, yes they would ideally all be at the same angle. Lookup bypass diode solar panel.

@@gridfreeordie are those built in to the panels or did you have to add those?

@@HandfulOfTranquility Buiilt into the smal boxes on the front or back of the panel. Nearly all panels have them but there are some cheap panels that do not. Commercial glass panels typically have 3 bypass diodes (one for each 1/3rd of the panel). You can also learn about about blocking diodes to prevent the battery or other strings of panels from dumping power into a shaded string. kzfaq.info/get/bejne/Y96PabJ9yafTlKc.html&ab_channel=DIYSolarPowerwithWillProwse - this video is mostly correct except the panel he shows has only 1 string of cells, and one bypass diode is in parallel with half of the 16 cells and the other is in parallel with the other half 16 cells.

​@@gridfreeordiehello sir, why do you need the batteries in the frunk? Isnt it possible to charge directly from the panels into the tesla battery??

@FirstLast-tx3yj The battery is required to handle intermittent clouds and my desire to charge at a fixed power during the day while the solar power follows a cosine curve. Apparently this inverter can go without a battery, but I haven't tried it. Nearly all off-grid inverters require a battery. I don't think I would achieve adequate data transmission if it were battery-less even if it worked without a battery because it may turn off and stay off if the charging load was more than input solar .
