So you might be wondering how solar panels work…. or you might not. I use a computer every day without having a precise understanding of how the actual processor works. I’ve looked into that briefly, but I am not going to waste my time when it would be better spent learning how to effectively use the technology. I feel the same way about solar technology, I’m happy to have just a basic idea of how it works.
This is the simplified explanation of how solar panels work. Solar energy hits the Earth as a particle that we refer to as a photon. When a solar panel is bombarded with photons, some of them are absorbed by the semi-conductor material (commonly silicon). Each photon that is absorbed can potentially shake loose an electron. An electric current is a flow of electrons. Solar cells are constructed with materials that force the free electrons to flow in one direction, thus creating an electrical current. A typical solar panel is composed of a group of solar cells joined in series and/or in parallel by a conductive material.
