A Solar panel produces about 250W peak per square meter. A parking spot can thus produce maybe three kW. A whole parking lot is probably enough for one or two chargers.
People would be unhappy with a charger that only worked slowly and during the day, even if it was free.
I would be utterly devastated.

A better version for shade and city beautification is to force trees around/within the parking lot.
I love seeing trees in more places, but for parking lots in particular they do have some downsides compared to solar panels. They often require more space; they attract birds that that poo on vehicles; and there’s a higher risk of collateral damage during windstorms. Not to mention that solar panels directly produce electricity, of course. We absolutely should see more trees in many cities, but they introduce their o…

how's the tree situation though? 110F + lots of huge trees = a lot more tolerable. trees cool shit down big time.
It's a desert so trees can't survive without irrigation. Since water is scarce as well, there aren't enough trees to cover the vast low density area.
What about https://en.wikipedia.org/wiki/Dracaena_cinnabari or https://en.wikipedia.org/wiki/Chilopsis?

I suspect they were mostly referring to it being uninhabitable due to the extreme heat and duration of 100ºF+ days.
A dry 100F is fine weather. I’ll take that over a midwestern winter any day.

Your car already has the battery built right into it, so a trickle charge for eight hours while you're busy at work might be enough to cover your commute.
2 kW over 8 hours would be enough for 100 km per day.
> Under a new decree approved by President Lee Jae-myung during a Cabinet meeting on March 11, mid-to-large-sized public parking lots with 80 or more spaces must install solar power generation South Korea is going to get a lot of 79-space parking lots.

Why not both?
They both are in competition for surface exposed to the sun. The mall’s parking lot near my place used to have trees. When they installed the solar panel shaders last year they cut down all of them.
The solar panels go over the parking spaces, like a kind of a bridge, with supports at the sides. There's a lot of space in between.
If the trees were in the same space as the panels, they'd be in the midddle of the parking space. What you'd have then is not a car park, but just a plain ordinary park.

I'm kind of struggling with the physics of this. The solar panels go over the parking spaces, like a kind of a bridge, with supports at the sides. There's a lot of space in between.

Sigh No, it's not. You can, and you should have trees in the middle of parking lots.

Dense multistory parking underground . In South Korea, you usually don't see parking lots the size of several football fields like in the U.S., even around venues that generally attract a lot of cars, even in suburban areas. Instead, there are several stories of parking lots under every large building. Above-ground space is simply too valuable to waste on parking. Unfortunately, you can't install solar panels undergr…
> Dense multistory parking underground. I sometimes forget there are parts of the world where you can go more than about a metre down without breaking out the Kango hammer.
But if the only alternative to blasting the bedrock is to pay through your nose for prime real estate, blast the bedrock you will.
