What solar energy is and how it works
- Photovoltaic cells
- Solar thermal energy
Solar panels are used to turn sunlight into electricity. A solar panel is made up of small solar cells. Each of the cells use light to make electrons move. The cells are made up of different layers that are stuck together. The first layer is loaded with electrons, and the second layer has had some electrons taken away, so that it is ready to take in more electrons. When the suns light hits an electron in the first layer, the electron jumps to the second layer. That electron makes another electron move, which makes another electron move and so on. That's how electricity is created using solar panels.
