A solar panel is the first component needed to setup a solar energy solution. It’s primary function is to absorb the sun’s light and to convert this energy into electricity.
How it works
Solar panels are mounted on the very top of a building roof, positioned to absorb the maximum amount of sun radiation. One solar panel is made up of many small solar cells. Each of these cells uses light to make electrons move. The cell is made up of two different layers that are stuck together. The first layer is loaded with electrons, so the electrons are ready to jump from this layer to the second layer.
That second layer has had some electrons taken away, so it is ready to take in more electrons. When the 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. It is the sunlight that starts the flow of electrons or electricity.
