Solar photovoltaic system, also known as photovoltaics, referred to as photovoltaic (photovoltaics; word source "photo -" light, "Voltaics" volt), refers to a facility that converts solar energy into DC energy by using the photovoltaic effect of photovoltaic semiconductor materials. The core of photovoltaic facilities is solar panels. Semiconductor materials used for power generation mainly include monocrystalline silicon, polycrystalline silicon, amorphous silicon and cadmium telluride. In recent years, countries are actively promoting the application of renewable energy, and the photovoltaic industry has developed rapidly. Distribution box manufacturer
