Number of Solar Panels to power a Level-2 EV charger?

And that is what percentage of the people in the US today? That's who we should be designing infrastructure for?
Obviously, they are not in your neighborhood but they do exist in very large numbers and they are not all getting nails done for $600.

No, we should be building a infrastructure that's actually efficient, resilient and as inexpensive as possible no matter the person. It's not about me, you, our needs and abilities.
Why even bother with things like superconducting power lines if we're willing to waste 10% of the electrical energy budget on things like wireless road charging boondoggles even if the technology works as promised.

Sure. Why not apply this to the entire economy?

We should all drive Nissan Versas, stay at Motel 6, live in hovels, eat only cabbage and potatoes etc, because providing more comfort or convenience for those who can afford it is of no value.

Just for some perspective, my home solar system has 23 400W panels ( coincidentally, total 9200W).

Averaged over a year, it produced 23KWh per day. So, basically, each panel is producing about 1KWh per day.

So if you want to power 20 chargers, with each providing 10 hours of charging per day at 9.2KW you will need:

9.2 x 20 x 10 or 1840 panels.

And a ridiculous amount of battery storage. The cost would be in the 10’s of millions of dollars.

Thank you for these numbers, it really helped me piece this together more.
