If you've got solar panels sufficent to charge a cybertruck then you don't need the cybertruck to power your home. Regular battery systems will work

Charging an EV from regular household solar panels would take days....

And that's assuming they are sunny days.

because solar panels only exist on houses?

Because EVs are only powered by solar?

Who said they were?

What? My BIL’s installation is small, roughly 8kWp, on sunny days he easily gets 40-50kWh, if not more.

The Cybertruck has a 123kW battery, so charging it would take days, assuming they are sunny days.

Wot?

It takes about a day to charge my Leaf on a small solar install.

But yes, it needs to be sunny.

I realize the person you're replying to wasn't specific and said just "EV" but a leaf and a cybertruck are pretty much the polar ends of a spectrum.

Ok but the problem with this argument is that you could come up with a hypothetical EV that can store enough energy to last a year and then take a year to charge.

And yet nothing prevents you from driving daily.

I think your math is off some how. I have a Model 3 and two Leafs and we charge them from our 39 400 Watt panels without trouble. They are always ready to go fully charged unless one of the boys has been doing more than normal of driving to the beach with a girlfriend and then borrowing the Model 3 for a concert, or whatever fun involves using all the stored energy at the same time (e.g. not commutes to school or work).

My 12 kw solar system charges my 32kwh battery in a few hours on sunny days. But to be fair, your system is even larger, and both of our solar systems are larger than average for home solar. A 5 kw system would indeed take days to charge a typical ev battery from zero to full.

There are many hours in a day and EVs are pretty efficient. You might struggle if your goal is to drive 200km per day but if all you want is to drive to work or go shopping, you'll be fine.

Let me know when you invent solar panels that aren’t vulnerable to damaging winds.

Where I live solar panels have been smashed by hail ice balls, 3 inches diameter.

Probably when they invent a genset that can sustain its surrounding structure being immolated in a wildfire?

I'm 100% off grid on solar in the middle of nowhere. My panels could burn up, get hit by hail, get searched by law enforcement, flooded out, eaten by mice, stolen by miscreants, abducted by aliens or buried in snow. And of course in the event of a volcano they are probably not gonna function well.

So they are of course totally unworkable in events when the power grid is down.

But I like using them and they've been reliable so far...

I know you're being snarky, but the chemical process for that exists! It's called the Fischer-Tropsch synthesis. You take air, CO2 specifically, and then run the process, which needs electricity, possibly from solar panels, and get diesel/gasoline/jet fuel out the other end! Isn't science amazing?

There are practical issues with it, but it's possible. The question is EROI or Energy Return on Investment. Do you get more energy from it than it took to make it, which unfortunately is not there yet. Shrinking it down to fit into your backyard is an exercise left for the reader.

it is more than possible - this is exactly what casey handmer and his startup terraform industries is doing in a pilot plant in the desert: https://blog.terraformindustries.com/2026/10/21/terraform-20...

Hyperspace Pirate tried this at home, and it's horribly inefficient: https://www.youtube.com/watch?v=jRKbjT8AoJw

Fischer-Tropsch uses CO, not CO2. You also need hydrogen. The input is not air but other hydrocarbons. Coal being the most common.
