What is a Solar Panel?
Solar power has been around since the late 1800s. Although it's not as well-known as wind or hydroelectric power, it's become one of the most popular ways to generate electricity. A solar panel is the most common way for people to make their homes more eco-friendly—and save money on utility bills at the same time! What exactly is a solar panel? What does it do? And how does it work? We're here to answer all your questions about these amazing devices. A solar panel is a collection of multiple photovoltaic (PV) cells. A solar panel is a collection of multiple photovoltaic (PV) cells. The PV cells are made from semiconductor materials that convert sunlight into electricity through the process of photovoltaics. The most common form of PV cell uses a material called silicon, but other materials like gallium arsenide and cadmium telluride are also used in small quantities. When light shines on the surface, electrons move out of their normal positions in the atoms and travel thro...
