This is an article about solar photovoltaic panels. Solar photovoltaic panels are devices that convert light energy into electrical energy using the photovoltaic effect. Solar photovoltaic panels are the basic components of a solar power system, and are composed of solar cells, busbars, cell strings, frames and outer frames. Solar photovoltaic panels can be divided into single-crystal silicon photovoltaic panels, polycrystalline silicon photovoltaic panels and thin-film photovoltaic panels according to their packaging methods.
