Actually, I Have looked and there is very little in the form of a readily available solar powered A/C. There are systems that you can piece together such as Mitsubishi's mini-split and you can buy inverters and the like. There are some "fringe" companies out there....but there is, to my knowledge, not a main-stream, easily-obtainable solar-powered A/C out there.
Here is one that I found that looks promising: Kingtech solar Solar Air Conditioner | Affordable Solar Air Conditioning
