Can you charge a car with these?

You'll get ~20 miles worth of charge per day in ideal circumstances (and you'll probably need an inverter.)

What? ~20 miles a day? Math please?

780 Whr per day is the ideal power generation on the spec sheet... you get 12 of them so you get at best 9.3 kWhr of per generation a day.

A typical EV gets around 3 miles per kWhr.... so at 9.3 kWhr of generation you get around 27-30 miles of range added to an EV with this setup. That's if all of the panels are set up optimally and getting sun the entire day.

From manufacturer: 780wh/day per panel in ideal circumstances

780wh*12 panels = 9360wh/day
EVs (as a whole) average 340wh/mile

So 9360/340 = 27 miles before inverter and charging losses. If both inverter and charging are 90% efficient, you're at 22 miles per day. When I'm making that many best case assumptions, I'm not going to give a number like 22 because it's too precise and people can pick it a part, ~20 covers my all my bases.

I recommend not to respond to these as they can easily check with chatGPT with one prompt. You waste your valuable 2 min just to type everything and respond.
ChatGPT and other AI will often be incorrect, especially on math, it's not a good source of info.

I was using ChatGPT for a lot of solar planning and it almost caused me to spend a lot of money on the wrong stuff because it was using the incorrect panel specs. There were multiple products on the page it was searching for the stats, and it came back with the wrong ones.
If you're going to use these, one has to verify the numbers it uses, the calculation it uses, and the result. If someone is just taking the answers and parroting them out to the world, they're going to look like a fool.

How many of these would it take to run a large window air conditioner in the summer? I would like to have a small battery is buffer but basically draw from the sun that same amount that the air conditioner uses in the same time.

Their unit is wrong. It's not 780 wh, it's 780 w a day. The rest if the math checks out. The w cancels out and you are left with miles per day.
It's 780wh/day. "780 w a day" makes no sense.

$0.36/watt is not terrible, if this is the amount of panel you need

Does it matter if this is an older or newer type of style of panel? I take it I will still need to purchase a type of track support that will hold these if I mount them to a roof?
