Solar energy is a type of fuel that’s powered by the sun. That’s really important because (hopefully) the sun will never run dry. We’ll never wake up one day and not see the sun. It’ll always be there (again, fingers crossed). Because the sun shines every day, it is the ultimate source of renewable energy (we’ll talk about that a little later on). We don’t have to refuel the sun unlike gas or oil.
Solar photovoltaics (also know as “PV”) take that sunlight and convert it into electricity, and we capture that electricity with solar panels. In those solar panels exist a ton of atoms (think back to 4th grade science for this). Atoms are the smallest particles of matter that we know of, and at the center of an atom is something called a nucleus (think of it as the heart or brain of the atom). The nucleus is made of tiny things called protons and neutrons. Solar energy works when the photons of an atom knock the electrons free from atoms, generating a flow of electricity.
Solar panels are made up of these small things called PV cells and many PV cells linked together make a solar panel. Most solar cells are made out of silicon. These solar cells are organized into sets or modules and then connected into solar panels, which you see on roofs.
