The science behind it: solar panels are usually made from a semiconductor in a metal frame with a glass casing. When this material is exposed to photons of sunlight it releases electrons and produces an electric charge. When solar energy is pumped into a battery, a chemical reaction among the battery components stores the energy. A special sensor, called a photocell, can sense the presence or absence of light. It can be programmed to trigger the LED light to turn on or off. Show more
