I admire what you are doing. I want a solar powered camper van or RV myself. I would easily sit in one spot and recharge for a few days and just relax knowing I would not be paying for gasoline, lol

Congratulations! So satisfying to set a challenge and then achieve it through pain and suffering, and answer a lot of questions... 64 panels is a huge amount to lug around though! I tried a similar task on a smaller scale with my ebike years ago, but with my own 120 W panels using 6 x A3 sheets of foamboard with 6 sunpower cells on each page, folded concertina style. Used polypropylene for some basic protection, but not rainproof! Came out at about 2 pounds in weight each, so was easy to carry 4 of them. Still work after 7 years! Each one took me about a week to make, so making 64 of them would be a nightmare!

That is really cool, I just checked it out. My panels are a little cumbersome but the prices have really dropped, I just put a link in my description, in the US the 100 Watt panels I used can be had for only 125 USD! Great that your setup is still working, I was thinking of something similar to your system that could fit in a backpack so I could charge my Onewheel and or Ebike. I also have a bunch of Maxeon cells should I choose to make something.

@@solarcannonballrun you can buy the solar cells individually and make up your own panels. I thought about doing this for a solar ebike, reason being you can get a specific voltage/amp. They cells are only like .6 volts but can do like 10 amps, very odd but you have too put a lot of them in series and you get a usable panel. I thought about keeping the voltage low and amps high and charge super capacitors that can handle 10 amp charging per cell, even 50 amp, something lithium cells cant do and why its the bottleneck in this system. Cant charge the cells fast enough, even if you have enough power. So i was thinking supercaps could work. fast charge them in parallel with 4volts 100 amps . Trick is you have to disconnect them from their series connection to parallel fast charge them which is actually possible with isolation modules, like dc-dc converter with isolation. This lets you charge batteries connected in series individually as if they were in parallel, allowing for fast parallel charging. Add the super caps into the equation and you could be super fast charging! Thats the idea anyway.

@solarcannonballrun

You can, but it is a lot of work, I see most people adapt existing panels to their needs rather than making custom. For best results you need a good MPPT charge controller and since they do all the conversion for voltage and current the panels become the bottleneck. My small tent battery (18650 cells) can charge at over 500w and I only used one 100w solar panel.

Nice challenge and great to see that this is possible. I wonder with the further development of cigs solar panels setting up could be made easier. They could be rolled up and rolled out easily. If you would have very large solar panels (some companies state 1000w panels is possible) you would only need 6 panels to get the same peak power. It would mean 10 times less connectors. Also CIGS is a lot less affected by shading. Maybe a trailer version would suit my electric campervan.

On normal dirt 40mph gust were just fine, this location was rocks mixed with silt. The lag screws would sometime go in but then pull out too easily, if I was free to move it around I could get a good hold, but that only worked for my single panel, with the full array I was too constrained by the wire lengths to get enough movement to find solid ground for each of the 192 stakes.

You did exactly what I wanted to do, but you did it on a much larger scale (longer journey). Congrats!! I just bought a Hummer EV SUV. I really want to charge it with solar at my house and on the road (at times). You took your DC power, stored it, converted to AC and then back to DC via your car's charger. I am furiously trying to find out from GMC if I can get an adapter for my charge port that can take direct DC input. After all, all you're doing is charging more lithium batteries inside the vehicle.... the car's battery SHOULD be able to handle unsteady current. I just don't know if reverse current would be a problem. For my vehicle, I know my PV voltage would need to be around 440VDC. I'm not sure if you already did the homework for the Tesla and realized it's not possible. If it is possible to do direct DC, can you imagine the increased charging time you'd get? Maybe 1 less day at each site ?

This will require some electronics voodoo to achieve. In any case, a charge controller would be required to maintain MPP of the panels, as if a cloud comes along and the PV drops below the battery voltage, no charging will happen as you're then attempting to run them in reverse.

On a simple lead acid battery system, you could direct connect a solar panel but the system efficiency would be very very low.

Yes it was around 6k, I plan to sell them along with the stands to recoup the cost. But totally worth it.

Thx!!!

Your use of the term Badlands, is a bit of a misnomer.

It won't be long before you absolutely fry your EV's onboard charger by using a high frequency, transformerless inverter. Because there is no galvanic isolation between the inverter's DC boost stage and its AC output. All it will take is for the AC output monitoring circuitry to fail and one of the MOSFETs in the inverter's H-Bridge circuit to short to ground, and this high frequency inverter can send dangerous, high voltage, high amperage DC current straight to your EV's onboard charger which will not only damage it, but can also set your EV's charger on fire.

Only 240lbs of panels? You could have bought a gas car and put 40 gallons of fuel in it for the same weight as the solar panels, and 1/50th the cost..... And not taken a full month to get to your destination.... You realize the cannonball record is 25 hrs? You might as well just tow a trailer with a generator on it.

Your videos are so old for some reason you always say in this one you say it’s November it makes no sense 0:53

This just shows you how awful electric vehicles are for any trip over 200 miles (if you are lucky in most of the US). Absolutely insane!

Or you could just use a supercharger and not do this guys experiment 🧐

I drove 1802 miles in a Tesla 3. I got 4.5 miles per kw. I only used 100 kw using a Tesla Fast DC Chargers for $.33 a kw or $33. The rest of the charging was done at Free Level 2 Chargers.

😃Question, why not connect all the panels in series and get to 400Volt and directly enter the DC connector, without going through the inverter and having a significantly greater efficiency?

I do have them linked in series and parallel, however the voltage is dependent on solar intensity and the car needs a consistent 400 volts as well as a communication protocol to initiate charge, this is the only off the shelf solution for now but not for long, there are controllers under development that could charge direct solar to car. I talk about this in another video if interested. kzread.info/dash/bejne/onqL1ZiFere_oLw.html
