Many people underestimate the number of solar panels needed to offset the energy consumption of an electric vehicle and normal daily use. I will run an experiment with a DIY solar setup charging my Cybertruck all day to see how many miles of range we can add. Additionally, I will show you a calculator where you can enter in your own EV, daily range, solar panel size, and a few other factors to get the number of panels needed for your own use case.

[@mwaldyke]

Here’s my example: I have a 6 kW solar installation that is good for about 40 kWh on a sunny day. From this I can add about 20 kWh to my Model Y if the car is home and can be charged during the day. I get about 4 miles/kWh, so about 80 miles added in a day. That’s more than enough for my daily driving. The catch is that if my car is at work with me, it’s not charging at home. I have a Powerwall, but its capacity is 13.5 kWh (about 11 kWh if I maintain a 20% reserve on the battery), so that’s the most I can get if I charge the car at night from the Powerwall. And clouds, rain, or snow can dramatically lower the output of the panels. The panels and battery cover the entire load from the house during the day when electric rates are high, and I charge the car at night when rates are low, so it works pretty well for me.

[@Juicememelord]

Wait... You bring in 40 kWh but your powerwall only holds 13.5 ....and you and 20 kWh to your car? How does that work?

[@mwaldyke]

@@Juicememelord The solar panels also power the house during the day. Any leftover production goes into the grid, and I get paid for it. DTE Energy no longer offers net metering, so I get about half what they charge to send me power, but my excess production gets used and I get some money for it.

[@brianmills4891]

This is good to show for the sake of reality. I get asked all the time why Tesla doesn't make their roofs out of solar panels. People who have never used solar don't really understand the amount of panels and consistent sun it takes. That being said, whole home solar is very affordable these days and people also do not understand how quickly a solar system pays for itself when you're offsetting the cost of gasoline or diesel fuel in a vehicle. Residential solar paired with an EV or two is a very good combination for personal finances.

[@Bercik87]

There should be at least an option for solar panels. This maybe couldn't charge the car to full in reasonable amount of time but could reduce consumption while Sentry is on, or at least offset this annoying Vampire Drain.

My son and I built an electric car about 12 years ago. I drove it to work everyday and charged it at work. We thought about using solar power to charge the car but the problem was that the car was at my workplace all day when the sun was out and back at home at night. The only way we could figure to use solar power at home was to buy another battery pack big enough to store the energy that could then be transferred to the car in the evening. This proved to be way too expensive at the time so we could not use solar power. If you have solar power available at work where the car is all day then you're all set.

[@everydaysolar]

That's sweet, did you guys retrofit an ICE car or build it from the ground up? What did you use for your battery pack?

@@everydaysolar A robotic tent that puts itself up and has very thin solar membrane members so it can stow well probably would work better than strong hail-resistant panels made for home, but current tech is bad for that since it breaks when it is bent. For now, the big challenge would be packaging it in such a way that the panels remain totally flat and low weight. The robot helps, since it could do a consistent job each time, but programming and engineering all this would be costly, and out of range of most corporations on something with such thin margins like this. But if this is solved, then it could conceivably turn into as large an array as someone can afford; perhaps 20kW? That's a lot of space, and would require some tricky wind tech to handle gusts. Currently very very difficult, but not impossible.

One think this shows is that with a pretty small setup you would still be able to have a working car in a total crisis where nothing around you works. Like after a big hurricane or other disaster.

Where an f350's diesel engine is made right here in the US. After all that, the 123kw lithium ion battery in my cybertruck is useless toxic waste cause it costs more to recycle it than it does for slave labor to get raw mats.

It would probably be about the same or worse results. you can drive 320 miles on the interstate, which is the cybertruck range, in about 5 to 6 hours. During that time, you probably won't be able to get more than a few kwh from the sun. If you consider that the highest rated residential panels are about 500 watts and the battery capacity of the cybertruck is about 123 Kwh, you would need about 50 panels to collect that much power over a five hour period.

[@majid_us]

I am adding this comment because I am not sure if the online calculator is clear enough for someone without technical background to fully understand it. The calculator is simply showing that one needs to use an inverter with ten 360-watt panels for 4.2 hours to add 30 miles to the Cyber Truck or 12KWH (0.4 KWH/mile * 30 miles). However, the calculator doesn't use KWH unit and is not aware of any battery storage (KWH). For example, you mentioned that you have 4KWH+4KWH of battery storage. So, "ideally", one can add 30 miles to the Cyber Truck much under 4.2 hours if the batteries are charged and the inverter is rated for the output current. The calculator is a good start but needs more parameters (e.g., battery KWH and amount of charge level). Average driver uses 30-50 miles per day and I have looked at the KWH numbers to get those miles and it requires a very small solar system (i.e., 10KWH for battery storage and 5KW rated inverter).

I'm pretty sure the math would cut the number of needed panels in around half, at least nearly with 700w panels. The issue is the startup cost, The higher wattage panels you get the less panels you'll actually need which means you can fit more that accomplish more in less space. But also those same panels cost more making it hard for many to justify buying the better ones when they can barely afford the average 300ish watt panels from Amazon or what have you as is. Regardless I would be interested in seeing the difference on a diy settup using a few 700 watt panels In the same ground configuration or even leaving the truck bed on the cyber truck open and letting it charge through at least one of them while you're driving around to see if it makes a good dent or not. Regardless awesome video, the more information people get on these types of situations and setups the better informed they can be about making a decision.

[@michaelfoster3441]

Great video Can you charge an electric car or electric truck using a Delta pro 3 and ecoflows Dual fuel smart generator combined , once the delta pro reaches 30% the smart generator can kick in at 2900 watts. And charge the delta pro back while you are charging the truck, could you charge the truck up fully using that method?

[@jamesdiserio4020]

Will an EV truck manufacturer ever put an MPPT input in the bed so u can charge it with panels - like on a campsite- for days when u are camping offgrid. Ecoflows solar generator works, but seems like it should be built into the vehicle.

[@everydaysolar]

That would be cool and more efficient if we could go DC to DC.

[@evchargerreviewsnet]

Cool test !

[@BoBo-tx9sp]

Entirely unrelated question, but what kind of plants are growing on your garage?

[@swilhelm3180]

Can one not charge the car directly off the panels without charging the battery then discharging the battery by charging the car? Seems wasteful. Of course an inverter would be used to match up the voltage.

[@benkanobe7500]

Isn't the question: "How many watts?" not how many panels?

[@liveyourdream7102]

put all thoes solar panels on a trailer roof and trail it with your cybertruck charging whole day long directly your cyber truck.. 2 benefits you have a lot of space loading stuffs on the trailer and your cybetruck is always fully charged ;-) only bad aspect is the needed parking and turning space ;-)

[@tomc.4860]

This big electric car uses a lot of power and so solar is a difficult sell. I ride an e-bike to work everyday and I do charge it off the solar panel in my RV. Because it's only a 12 amp hour battery it is very feasible to charge it off solar power

[@MrGanbat84]

Add BYD cars in the calculator

[@benkanobe7500]

Would it hurt the Tesla if you cut out the Delta Pro battery and had an enphase Iq8 or Hoymiles 2000 micro inverter connected to the panels and then directly connected through the NEMA 50 to the Tesla's charger?

[@iguanaman08]

It's so inefficient to have DC current from the panels to a power station which is AC. Then the Tesla has to convert back to DC to charge it. I have seen systems that charge an EV direct from panels to via DC to DC charging. Let's hope the price comes down though on these systems.

[@PrestoMoto02]

You need about 20kw of solar if you drive it everyday

[@Reelbassin]

its kind of crazy how much the capacity of EV batteries is. I would've thought 3kw would do more but that's the sad reality.

[@johnkayak10]

So about $2.38 worth of diesel for my chevy Colorado 2.8 diesel that gets 25 miles per gallon How many days equals payback for the cost of that equipment?

[@charlesk46563]

Saved around $3 a day on gas, around $1000 a year, solar panels at $300 x 10= $3000 ecoflo delta $2000 wires and controllers $500 total around $5500 so it would pay for it self in only around 6 years.

[@anthonymalovrh2912]

Calculator did not work for me. Have had solar since 2008.

[@everydaysolar]

Hmmm, thanks for letting me know. What web browser are you using?

[@23rdsphotographyandaerials93]

You only need one but have to wait 12 months for it to charge 😂

[@everydaysolar]

Sounds about right 😂

[@greggg4011]

Using your method you're going to use up battery cycles. Why aren't you trying to generate 660W and using the 110 charging plug?

[@PeterSedesse]

The easier math is this. On an average day, you can charge about 30 miles of charge per1000 watts of panels in good weather for a regular ev (not the cybertrash). But that is well placed panels that are going from sunrise to sunset. You didn't really start yours until 11am? I mean I looked at :15 and you were setting your panels out in the shade and it was clearly daylight already. 30miles per 1000 watts per day.

[@rustyheyman214]

Interesting. Renting with a plug in and work from home in SoCal. Would like cheap and easy portable system to charge my car.

[@keithrosenberg5486]

Obviously if you do a lot of driving, you will need a lot of solar panels to charge your Tesla. Or a grid connection. Now for a word problem in mathematics. Calculate going across the US in your Tesla using nothing but the solar system it can carry along. How long would the trip take?

[@everydaysolar]

There was a guy recently that did a "Solar Cannonball" run coast-to-coast and took around 60 days.

[@keithrosenberg5486]

@@everydaysolar That does not surprise me.

[@DxModel219]

the problem with pro installed vs diy is a pro install is 10x this cost vs diy with maybe 60% the effectiveness

[@6YJI9]

I am watching this video at 2am and under the influence of medication & alcohol, but it does sound like to me that the math ain't mathing around the 6:00 mark. You're talking about only adding 7 kwh worth of energy into the cybertruck total, but then at the same time mentioning having a 3 kw solar system. So the way I look at it is, your 3kw solar system would produce 3kw/h, you waiting to start counting at 10am would still give you a very good decent amount of solar energy with let's say 6hrs, so 6hrs times 3kwh equals 18kwh sent over to the cybertruck. I don't think my math is wrong, or that I'm missing something. But at the same time, I want to ask everyone else if his estimate/logic seems off, or if it's me indeed missing something?

[@Madsci-zy8wm]

Because that cheap, high frequency, transformerless inverter offers no galvanic isolation between its DC boost stage and its AC output, one day you will fry your EV's onboard charger and will void your EV's warranty. If you want to safely charge your EV with solar, you should be using a low frequency, transformer based inverter.

[@everydaysolar]

I wasn't under the impression Tesla had any restrictions on what type of outlet is used for charging in their terms and conditions.

[@ag4eng]

Doesn’t seem to be worth because the panels+battery will be expensive and 1/3 loss is not very efficient.

[@Terrillthegreat79]

Any thoughts on the EV roof rack solar systems? Would you review them?
