Solar Photovoltaic Panels

 Solar photovoltaic system, also known as photovoltaic, or PV for short (Photovoltaics; etymology: "photo-" means light, "voltaics" means volt), refers to a facility that uses the photovoltaic effect of photovoltaic semiconductor materials to convert solar energy into direct current electricity. The core of photovoltaic facilities is solar panels. At present, the main semiconductor materials used for power generation are: monocrystalline silicon, polycrystalline silicon, amorphous silicon and cadmium telluride. As countries have been actively promoting the application of renewable energy in recent years, the photovoltaic industry has developed rapidly
