If you just need a solar panel to keep your battery charged while in storage then the Solar Battery Charger part # PTW2997 will be perfect for this and you don't have to worry about overcharging either. I am not sure what you mean by using the battery to keep them on but the above will not draw any power from your battery.

If you want something to actually provide a charge when you are actively using the battery then you can use the Go Power Eco Solar Charging System with Digital Solar Controller part # 34273837 which also has a maintenance charging cycle for when in storage.

For reference, the former panel puts out 2.5 watts and the latter puts out 20 watts.
