To charge a 12v battery like those in automobiles in the most eco-friendly manner, you must use a solar battery charger instead of the traditional battery chargers that use fossil energy. Charging car batteries using a solar panel charger ensures an efficient and eco-friendly battery charging process. The solar cells or the photovoltaic cells of the panel use solar energy to generate electricity in direct current (DC), which helps charge car batteries. A 12v solar battery charger has solar panels on the face, and you must place the charger near a window or on the dashboard to allow direct exposure of the panels to sunlight during the day. The charge accumulated during the day is useful for charging the battery at night, although you can even charge the battery at any time of the day.
