That's a really small panel. If I had to guess, judging by the size maybe 10 or 15 watt? At that size it could be just a battery maintainer. I can't imagine it having anything to do with the AC unit, but just a convenient place to mount a small panel for some sort of accessory or as a battery maintainer.
