My best performer is my 100w harbor fright panel which has maxed at around 100w real world use. It's less impressive when you factor in how big, heavy, and expensive that panel is...
If you use something small like a EF portable AC in a small car, it's possible with a few panels and a solar generator.
If you have a 12VDC AC system (or 24 or 48VDC) that's installed on the back of a semi cab, or a camper/rv. You can theoretically run it with a largish (let's say 8-20kwh) battery system. But the amount of solar is needed would be dependent on your AC size and amount of space you're cooling. And how much sun you can get. Theoretically, for a small 12VDC AC system, you'll need about 1500W of panels (about 8 of these panels, which yields about 1000W on a sunny day to run it under the sun). When the sun goes down, the batteries will take over gradually and provide some additional running hours. But you'll need a large bank to run it overnight, and have additional panels to charge the batteries back up the next day. Or with a DC to DC charging setup while the engine is running.
Is it cheap? No. A single panel here will only provide power for small loads.

This guy tested a few 100w panels. Renogy was best in terms of power/size, but EW had best power/$. HF "100w" panels are probably more than 100w, but just being sold as 100w
In the 90s, I believe Audi had a car with a solar panel built into the roof to power the fan. The AC compressor would be too much.

Harbor fright is my new nickname for that store
