I think your A/C would be more - but I'm not certain
If you had Solar panels deliver this power, you could get similar power if you spent ~$1.5k on a panel 6.5 ft X 16 ft
Most (US) homes put outlets on a 15A breaker (sometimes 20A), which gives have 1.8 kW to play with. So this is less power than a typical home outlet.

A/C definitely requires far more power—you have to deal a high peak load for motor start. Absolutely not happening with this setup.
The applications of this are rather curious, and definitely not for the any typical person. Probably defense, with a very short lead time, with the need for faster mobility?

Yes, definitely. And it can still be highly mobile: https://www.youtube.com/watch?v=VTiDklyEYaI (and once a setup is at a location, you could throw it on the back of a truck for some short-range transit. You'd just need to spread out the solar in each new place. FWIW, Solar and Microwave both have interesting yet different line of sight requirements.)
US outlets run at 15A, but per the NEC [0] no single plug-in appliance can continuously pull more than 80% of the max rating, or 12A. Which is why space heaters all max out at 1500W instead of 1800W. But an intermittent appliance, like a hair dryer or toaster, can pull the full 1800W though.

I think some people have probably experienced this first hand -- if you just barely overload a breaker, it might take a little while for it to break, and if you turn it back on, it might stay on a little bit before breaking again. And if you really overload it or short it out, it'll break right away. This is all by design.
It depends on what size A/C we're talking about. After all, window units run off a regular 15A wall plug.
I've also run an RV A/C unit manufactured around 2006 at about 13 amps continuous draw during duty cycle, insignificant surge at startup, with a 3 kW inverter (plenty of capacity left over) and LiFePO4 batteries.
Make that A/C 10+ years newer and it would draw a a few amps less, too.
And if the surge is too much, there's an extra gadget you can install in the A/C that's essentially a capacitor for smoothing the surge.
I'm not saying line-of-sight transmission is a great solution, but this is an impressive engineering demonstration with some limited battlefield application.
Perovskites open the possibility of printing your solar cells on flexible films, so the panels can be unrolled like projector screens or greenhouse roofs, and rolled up again.[1]
10-15 kW of panels and suitable batteries would get you near 1.6 kW continuous.
This (microwave power beaming) is for battlefield applications, where mobility is primary.
1. Several groups are developing these. For example in Australia, https://www.csiro.au/en/research/technology-space/energy/Pho...
Moderately long distance wireless power transmission has a whole host of applications.
