This process, known as a PP (proton-proton) chain reaction, emits an enormous amount of energy.

  • How do solar panels produce electricity?

  • When the sun shines onto a solar panel, energy from the sunlight is absorbed by the PV cells in the panel. This energy creates electrical charges that move in response to an internal electrical field in the cell, causing electricity to flow.
