Can you charge a car battery with walkway solar lights?
Answer:
Of course you can. You'd need enough solar panels to get 14V, a suitable diode to prevent reverse flow, lots of sunshine and plenty of time.
Car batteries are pretty powerful, and the car's starter motor draws a lot of power. You'd need to invest lots of time into the charge before you try starting the engine, 'coz if it fails, your engine isn't running still, and your battery will be drained all over again.
It would probably be easier to start your car by rolling it downhill, gearbox permitting.
