I currently have a small solar panel which I think is 1.5w and does very little. My car can sometimes be left for over a week without being used. My car is supplied as new with a 063 battery, and as the battery tray is big enough I have fitted a 096 battery instead for extra capacity. I use an A129 with the 3 wire kit.
The main options seems to consist of panels that connect to the cigarette lighter (assuming it is constantly on) with a diode to prevent battery discharge when dark. The alternative is a panel with a solar charge controller which reduce the voltage output of the solar panel from about 18v to 12v.
Any good options exist to try prevent parking mode draining the battery by trickle charging with a solar panel placed either on parcel shelf or dashboard?
At what wattage would a solar charge controller be necessary to prevent battery damage?
