went back few pages and didn't see this mentioned so here goes. My docks don't have power so would like to find dependable solar panel source to do trickle charge for my trolling motor battery in front of my pontoon. Tried one from auto parts place but if you look at fine print it says will drain power if left overnight and I am not with my boat most of the time. Anyone had success doing this? thanks so much as you guys usually have solutions to most folks issues.
