A photovoltaic or solar cell is made from a semiconductor material like silicon. The semiconductor material in a solar cell releases electrons when sunlight hits them. These electrons are then captured by electric conductors. When the conductors are connected with an external device such as an appliance, battery or other power source, electricity flows. The connections to solar cells are typically made in thin wire-like circuits. These connect between a tempered glass piece and a backing pane of mirror image glass. These are the main components of a panel or solar module. The circuits within a panel capture solar energy and generate direct current (DC) electricity. The energy is converted to AC electricity by connecting wires to inverters. This power can then be used immediately by power companies or at home.
