Solar panel stopped working

Getting no power from solar panel. Switched to batteries. I had this problem earlier in the summer. It was suggested it could be from water getting into the panel’s battery compartment. I wasn’t sure if it had the drainage hole, but looking at it now, I see that is does. Could it be that it’s no longer charging because the sun angle is too low at this time of year? During the summer it seemed to be from consecutive cloudy days. It powered up again once it became sunny. So I guess my question is, how much sun does this thing need to work properly? Has anyone had it work consistently? Or does it tend to just stop working?
