I have Wildgame Innovations and the cheap American Hunter in 6V.
Since I feed year around, they are out there all year for years until they die!
The plastic cover on the Wildgame Innovations became cloudy and crazed/cracked over time and output dropped off after 2 years in the sun.
The American Hunter is the glass with aluminum frame that has wire and small alligator clips on battery end.
I have 3 of these that have survived for over 5 years in use year around.
I do have to clean off the corn dust every once in a while if it doesn't rain.
I've found wires pulled out and chewed off by coons and squirrels to be more of a problem than panel life in most cases.
