Because they don’t generate enough power. You would have to leave your car out in the sun for a day in order to drive 10 miles.
Toyota did it on a few Prius models...ran a ventilation fan in hot weather to keep the inside of the car cooler.

Why doesn’t Jao Biden wear a beanie cap with a spinner on it to get around instead of AF1?
Solar panels on riding mowers might be a good idea though. Most people cut the grass when it’s warm and sunny.
Why don’t they have solar panels under the car?
Two batteries. A generator charges one while the other is being used. Just a thought.
And hey... What about a wind generator on the hood?
Hmmm...
Most commercial solar panels deliver less than 20% efficiency.
In fact, because of basic laws of physics, almost all current solar panels have a maximum efficiency that is less than 30%.
Yeah, keep telling that lie. 60% is rare and it ain't efficient. Only the numerically illiterate believe crap like this.
Little snowflake pussy boi: "Oh it's just another trillion dollars, but the earth's core has be raised to a million degrees by man made global warming, and billions of people die each year because of it. We have to save the earth and it is worth every dollar we spend."
Garages would be useless. You would have to park your car outside at night to charge the battery.
Tesla is claiming that its superchargers will be 100% powered by “renewable energy” this year and “almost all” will be disconnected from the grid.
They also said you would be able to buy your Tesla with bitcoin. /snicker
An Audi Etron electric SUV, for example, has a 100 kWh battery, with a range of over 200 miles.
With a 240V, 30 AMP level 2 household charger, that’s about 9 (nine) hours of charging to get it from ‘empty
to full.
A 365W LG Neon 2 solar panel is 3.5’ X 5’. So MAYBE you could mount 3 of them on a bimini canopy above a vehicle. Full sun you might be getting 1100W.
Do the math. Ain’t gonna charge that vehicle very fast, but it WILL charge it eventually.
“WHY DON’T ELECTRIC CARS HAVE SOLAR PANELS ON THE ROOF?”
They don’t have enough capacity. What a bunch of BS.
We all know the REAL ANSWER:
It’s the OIL COMPANIES and BIG POWER conspiring to limit solar flux on the rooftops of cars. Get them out of the way, and rooftop solar will take you from here to California, with only having to stop at night!!!
I hate these BS articles.
Cars are mostly sold by their cool looks. If the Tesla looked like a golf cart, even if it was the most efficient electric car in the world, it wouldn’t sell well. (Also, oddly enough, it wouldn’t sell well if it was cheaper than an equivalent gas car.) Lots of manufacturers in the thirties, forties and early fifties thought the public wanted a small, efficient car. Bantam comes to mind. It turns out people want sex appeal, or, at least not to stand out as different*. Also, when someone wants to drive the family from Florida to Ohio, they do not want to listen to the wife complain about long, uncomfortable periods when the car is charging. When it comes down to it, a man will do handsprings to avoid listening to the inevitable complaints. Using a gas car is a lot less strenuous than handsprings.
* I think the VW Beetle didn’t catch on until it became the symbol of hippie generation. THEN, it was okay to be different, to make a statement.
how about a gas powered generator in the trunk? i know the technology is untested but worth a shot.
