The solar energy of the Solar panels promise to lower your electricity bill by supplementing the energy you buy from the local power companies.That is good, but choosing and installing solar panels can be an overwhelming task. Solar cells, which are linked together in a panel, convert sunlight into electricity via photovoltaic materials, such as silicon. When sunlight hits these materials, the light's energy is absorbed, and that energy causes electrons within the material to escape from their position in the atom of silicon or other photovoltaic material. These released electrons are captured to produce an electric current.
