Propane powered AC?
Since the fridge can run off propane; why can't a roof mount AC be ran off propane?

For comparison, an RV frig is about 4000BTUH. So think how large a Gas/absorption unit would be for an 15,000BTUH A/C unit....plus HEAVY.
Years ago, Bryant offered a home gas/absorption A/C unit, and it was rather large.
As for absorption A/C units in commercial applications, there are still making them as water chillers and are also used in industrial applications that have waste heat to drive them.
Battery banks with an inverter to run one or two 15,000BTUH A/C units would be heavy as well as expensive. Just look at how many batteries you have to have to run a 600 Watt refrigerator.
Next issue is the solar cells to keep batteries charge for long term use.
One roof top unit will need about 1800 Watts. On 12 VDC, they will need 150 amps , not allowing for starting and efficiency loss in the inverter.
You best bet is a generator to power the standard roof tops.
