Italy BASS, I didn't have solar on these, but I do on all my feeders now. The Moultrie's only have a single corn type slinger, so they really don't take much juice.
IIRC, I got 3-4 months out of a battery charge, but I would always have a spare battery and small maintainer/charger onsite. Especially if fish food is the primary food source for your fish.
