How Do Solar Panels Work? Solar Power Explained

In a nutshell, solar panels generate electricity when photons (those particles of sunlight we discussed before) strike solar cells. The process is called the photovolatic effect. First discovered in 1839 by Edmond Becquerel, the photovoltaic effect is characteristic of certain materials (known as semiconductors) that allows them to generate an electrical current when …
