This unit draws 5-6amps when the compressor runs. A 100amp battery will run it, but the charge back from a 100w panel might not be sufficient to maintain the battery. It will depend on how often the compressor needs to run and how much charge back is achieved during the day.

It is pretty easy to calculate solar, generator and battery needs based on your information. The other missing data is run time which I find is highly dependent on ambient temps. I would plan for at least 80% in order to run the unit in low to moderate Summer temps. Anyway the 100AH battery is going to provide 50AH or a run time of less than 10 hours. I would want at least 4-6 batteries to avoid using the generator every few hours. Solar is a different issue. Right now where I live in NY a roof mounted, 100 watt solar panel is only going to provide about 40 AH/day of power. So under ideal conditions it would take at least 2 panels to break even. With about 50% cloud cover this time of year, that would mean 4 panels and more if you park in any shade or have an extended rainy period.
