Solar panels generate electricity by converting sunlight through the photovoltaic effect. While they do not produce significant electromagnetic radiation on their own—like any object exposed to the sun—they emit thermal radiation in the form of heat and reflected light. It's a fair question – we're talking about electrical systems on your roof, after all. These waves include radio waves, microwaves, infrared, visible light, ultraviolet rays, X-rays, gamma rays, and more, spanning a wide range of frequencies from low to high. Radiation refers to the emission of energy in theForm of waves or particles. There are two primary types of radiation: ionizing and non-ionizing.
