How does rooftop solar power work?
Light from the sun, or more specifically, photons from the sun (aka solar energy) hit the photovoltaic (PV) array which causes an electric current to be generated. This process is the result of atoms becoming excited, allowing the flow or shifting of electrons to take place within a PV cell.
