How Solar Energy Works
Solar electric or photovoltaic systems convert some of the energy in sunlight directly into electricity. Photovoltaic (PV) cells are made primarily of silicon, the second most abundant element in the earths crust, and the same semiductor material used for computers.
When the silicon is combined with one or more other materials, it exhibits unique electrical properties in the presence of sunlight. Electrons are excited by the light and move through the silicon. This is known as the photovoltaic effect and results in direct current (DC) electricity. PV modules have no moving parts, are virtually maintenance free, and have a working life of 20-30 years.
Solar energy is a major contributor to the overall growth of renewable energy resources, and global output is expected to be 26GWH by 2025.
Solar panels can be used in almost any location where they will be exposed to direct sunlight. They can be placed in open landscapes, on land that is not suitable for agriculture or construction such as steep hillsides, and they can also be used as decorative cladding on buildings or even as moveable sunshades covering office windows.
