Gasoline Fumes,

Great idea. I've ordered this charger for 18.79.

How did you splice the barrel plug to the dome wire, and which wire?

I know that the partly-drained battery will recharge the next morning. I park facing the morning sun! The panel will also recharge a dead battery enough to start an engine. Of course it'll take a few hours, but it will do it.
