Solar Photo Voltaic (PV) UK Utility-scale solar photovoltaic technologies convert energy from sunlight directly into electricity, using large arrays of solar panels. Solar photovoltaic technologies convert solar energy into useful energy forms by directly absorbing solar photons—particles of light that act as individual units of energy—and either converting part of the energy to electricity (as in a photovoltaic (PV) cell) or storing part of the energy in a chemical reaction (as in the conversion of water to hydrogen and oxygen). Solar cells are devices that convert sunlight directly into electricity. Solar cells are made of layers of semiconductor materials similar to those used in computer chips. When sunlight is absorbed by these materials, the solar energy knocks electrons loose from their atoms, allowing the electrons to flow through the material to produce electricity. A brief animation titled "Sunlight to Electricity" that shows how a solar cell works is available on the Animations page of the Department of Energy Solar Energy Technologies Web site. Photovoltaic modules: Due to the low voltage of an individual solar cell (typically ca. 0.5V), several cells are wired (see: Copper in photovoltaic power systems) in series in the manufacture of a "laminate". The laminate is assembled into a protective weatherproof enclosure, thus making a photovoltaic module or solar panel. Modules may then be strung together into a photovoltaic array. Photovoltaic arrays: A photovoltaic array (or solar array) is a linked collection of solar panels. The power that one module can produce is seldom enough to meet requirements of a home or a business, so the modules are linked together to form an array. Most PV arrays use an inverter to convert the DC power produced by the modules into alternating current that can power lights, motors, and other loads. The modules in a PV array are usually first connected in series to obtain the desired voltage; the individual strings are then connected in parallel to allow the system to produce more current. Solar panels are typically measured under STC (standard test conditions) or PTC (PVUSA test conditions), in watts. Typical panel ratings range from less than 100 watts to over 400 watts. The array rating consists of a summation of the panel ratings, in watts, kilowatts, or megawatts. Photo Voltaic Electricity: By utilizing the sun and PV cells, made from thin panels of semiconductors to convert radiation found in the sunlight into electricity. Solar power wouldn't be affected by the demand and supply of fuel for this is free of charge also it does not pollute the environment. It's always natural and pure. It might give you far better overall health. To know more about PV, visit greenutilities.co.uk. For more details check Related Articles -
