Monocrystalline silicon is a high-purity, single-crystal form of silicon used to manufacture the most efficient and premium solar photovoltaic (PV) cells on the market. It is called “monocrystalline” because the silicon used in these panels is made up of a single crystal structure, unlike polycrystalline silicon which is made up of multiple crystals. With their sleek, black appearance and high sunlight conversion efficiency, monocrystalline panels are the most common type of rooftop. . Solar panels are composed of multiple solar cells, typically made from silicon or other semiconductors, which convert energy from sunlight into electric current. This conversion is driven by the photovoltaic effect, in which photons from sunlight excite electrons on the active semiconducting layer. .
