Using solar panels to power small electronics may afford you a sense of security when dealing with an emergency situation. Solar panels can also be used to charge 12-volt batteries found in vehicles or portable "jump packs." Solar panels work by converting the energy produced by the sun into usable electricity. Connecting a 12-volt solar panel to a 12-volt rechargeable battery can be accomplished without special tools or skills.

  1. 1

    Examine your surroundings for a proper place to situate the solar panel. Choosing an area that features direct sunlight will yield the best results.

  2. 2

    Determine the type of electrical connections your solar panel may have. If available, utilise the solar panel's cigarette adaptor when charging a vehicle's battery; place the solar panel on the dashboard, in direct sunlight. Certain portable "power packs" may feature a cigarette-lighter port for charging.

  3. 3

    Connect the solar panel's colour-coded alligator clips to the corresponding terminals on 12-volt, rechargeable-battery applications. The "red" alligator clip connects to the "positive" battery terminal. The "black" alligator clip connects to the battery terminal marked "negative."
