  • Else, are solar car battery chargers any good?

    The good thing with solar chargers however is that they are pretty low powered – that's why they are perfect as trickle, or maintenance, chargers. So don't leave them on permanently, as they have no overcharge protection. But it's unlikely you'll do major damage if you disconnect after a few hours in the sun.

    Briefly, can I leave a solar trickle charger on all the time? Charging your vehicle battery with a solar trickle charger is easy and can even be done on a continuous basis. Just connect the device and leave the solar panel on your car's dashboard. You will probably forget it is even there. It can be for new or old vehicles, it does not matter.

    Nevertheless, what size solar panel do I need to charge a 12v battery?

    For a 12V system, if you need to replace 100A/h of charge to your batteries each day, and you have 8 sunlight hours in each day you will need... 1200WH / 8H = 150W of solar panels. In reality it is recommended that you always overrate your requirements by at least 20%, therefore you would need 180W of solar panels.

    How long does it take for a solar panel to charge a car battery?
