Solar panels are a great way to save money on your energy bill and help the environment. Solar panels are semiconductor devices that convert sunlight into electricity. Solar panels are made of silicon, a material that is found in sand. Solar panels are usually made into solar cells, which are then connected together to make solar PV modules or solar panels. Solar panels are used to power homes, businesses, and public facilities such as schools and hospitals. Solar panels can be used to generate electricity for a single home or for a large commercial or utility-scale solar power plant.nnSolar panel systems can range in size from a few solar cells on a small roof to a few thousand solar cells on a large roof. Solar panels are typically made of polycrystalline silicon, which is a material that is made from crystalline silicon dioxide. Solar panels are also available in monocrystalline silicon and amorphous silicon.nnSolar cells are made of semiconductor materials, such as silicon, germanium, gallium arsenide, and cadmium telluride. Solar cells are connected together in series to create a solar panel. A solar panel may have anywhere from 30 to 300 solar cells connected together in series.
