Solar watches are equipped with a solar panel, which absorbs sunlight and converts it into electrical energy through the photovoltaic effect. This electrical energy is then stored in the watch's rechargeable battery, which powers the watch's movement and other functions. You've probably seen many posts giving you a basic understanding of how solar watches work or how they work. The process begins when sunlight, or even artificial light, hits the solar cells, exciting the electrons within the material and generating electricity. Technology has found a way to harness a bit of that energy and use it to power timepieces.
