I am 'aware' of such, like the kind that one might find in an RV.
These units are small, but still consume quite a lot of power.

This is a nice thought. However such a unit is not common. Such small
production quantities would make them quite expensive. A more cost
effective route would be to get an 'off-the-shelf' AC unit and use a
DC->AC converter.

Ya know, from time to time I read of these 'break thorughs' in
photo-voltaic production technologies. But I don't see the price drop
all that much. Are cheap PV cells being kept from us, or are they
being snached up as soon as they pop out of the toaster?

I doubt they exist, Cathy.
As I had mentioned, they are no doubt cost prohibitive. After all -
the idea, here, is saving money, right?
Something I have dreamed of was an 'absorption' cooler for the home.
This is practically free 'cold,' but the unit would be many times the
size of that five-ton that's on the roof now.
The summers are hot here - expected to be 105 again today. The house
is designed to handle the heat with grace. Still, that AC will
probably be turned on, if the humidity rises. At 25-cents an hour
running time, how nice it would be to get my cold for free!
Stay cool...
