When you start talking about running an A/C, you are talking about MANY more components than just solar panels.
You will need an Inverter, a minimum of 5 deep cycle, high amp hr batteries, LARGE solar controller, heavy gauge wiring [8 gauge] for panels to controller, 04-06 cables from inverter to batteries, 8 x 100 watt solar panel at least. An automatic transfer switch is a big help, but can be worked around with some trouble. Several large amp fuses and at least 2 breakers to disconnect panels and batteries from controller.
If you want to run a small A/C [13,000 btu] for 3-4 hours, then you can scale down SOME, but not much. Maybe 6 x 100 watt panels.
Batteries are the heart of the system and with
out them, meaning usable amp hrs, you will be very limited as to what you can run and how long.
Make sure you use a MPPT solar controller as they are much more efficient than a PWM unit.
Depending on where you live or camp, your exposure to optimum sun conditions will be a big factor. Here in SE Georgia, we get over 12 hours a day of sun during the summer and about 8 during the winter months.
