I have two DURAVOLT marine solar panels on my boat to keep starting, home and trolling engine batteries charged. I keep my boat in the water and before using the DuraVolt solar panel my batteries were dead and my bilge pumps couldn't handle the rain. I've been off the boat and haven't seen it for maybe two weeks and this problem has always bothered me. Now for the past 3 seasons I have had a 12 volt DuraVolt solar panel plugged into my cigarette lighter and when I go to the boat the volt meter reads 12.6 volts. Full load. I also hooked up a 24v DuraVolt cycle battery for my trolling motor and it's always ready to go.
