Solar panels function by converting sunlight into electricity through a process known as the photovoltaic effect.

  1. The solar panels are composed of silicon cells that are struck by sunlight.
  2. The photons in the sunlight dislodge electrons from their atoms in the silicon cells.
  3. The freed electrons move through the silicon cells, generating an electrical current.
  4. This electric current is then captured and transformed into usable electricity.

In the 19th century, French physicist Alexandre Edmond Becquerel discovered the photovoltaic effect, which served as the basis for modern solar panel technology.
