The Science Of Solar Panels

The silicon has electrons in it that when hit.

The science of solar panels. A module is a group of cells connected electrically and packaged into a frame more commonly known as a solar panel which can then be grouped into larger solar. Solar energy radiation from the sun capable of producing heat causing chemical reactions or generating electricity. Simply put a solar panel works by allowing photons or particles of light to knock electrons free from atoms generating a flow of electricity. In such cells a small electric voltage is generated when light strikes the junction between a metal and a semiconductor such as silicon or the junction between two different semiconductors.

Solar pv panels are comprised of many small photovoltaic cells photovoltaic meaning they can convert sunlight into electricity. The solar panel is made up of silicon wafers that have wires attached inside to transfer the energy to the location that it is needed. The solar cells that you see on calculators and satellites are also called photovoltaic pv cells which as the name implies photo meaning light and voltaic meaning electricity convert sunlight directly into electricity. The science behind solar pv cells.

The total amount of solar energy incident on earth is vastly in excess of the world s energy requirements and could satisfy all future energy needs if suitably harnessed. The term solar panel is used colloquially for a photo voltaic pv module. Photo voltaic cells use sunlight as a source of energy and generate direct current electricity a collection of pv modules is called a pv panel and a system of panels is an array. Now that we have a basic idea of the generation and flow of solar electricity let s take a deeper dive into the science behind the solar photovoltaic panel.

Solar panels actually comprise many smaller units. Solar energy is gathered by using solar panels to convert the sun s energy into electricity. The science behind solar energy how is solar energy gathered or created.
