  2. Photovoltaics - Wikipedia

    en.wikipedia.org/wiki/Photovoltaics

    Photovoltaic modules were first mass-produced in 2000, when the German government funded a one hundred thousand roof program. [4] Decreasing costs has allowed PV to grow as an energy source. This has been partially driven by massive Chinese government investment in developing solar production capacity since 2000, and achieving economies of ...

  3. Photovoltaic system - Wikipedia

    en.wikipedia.org/wiki/Photovoltaic_system

    A photovoltaic system, also called a PV system or solar power system, is an electric power system designed to supply usable solar power by means of photovoltaics.It consists of an arrangement of several components, including solar panels to absorb and convert sunlight into electricity, a solar inverter to convert the output from direct to alternating current, as well as mounting, cabling, and ...

    en.wikipedia.org/wiki/Solar_panel

    The performance of a photovoltaic (PV) module depends on the environmental conditions, mainly on the global incident irradiance G in the plane of the module. However, the temperature T of the p–n junction also influences the main electrical parameters: the short circuit current I SC , the open circuit voltage V OC and the maximum power P max .

  6. Concentrator photovoltaics - Wikipedia

    en.wikipedia.org/wiki/Concentrator_photovoltaics

    The optics needed to concentrate the light have limited efficiency themselves, in the range of 75–90%. Taking these factors into account, a solar module incorporating a 44% multi-junction cell might deliver a DC efficiency around 36%. Under similar conditions, a crystalline silicon module would deliver an efficiency of less than 18%.

  7. Solar cell - Wikipedia

    en.wikipedia.org/wiki/Solar_cell

    A solar cell, also known as a photovoltaic cell (PV cell), is an electronic device that converts the energy of light directly into electricity by means of the photovoltaic effect. [1] It is a form of photoelectric cell, a device whose electrical characteristics (such as current , voltage , or resistance ) vary when it is exposed to light.

  8. Outline of solar energy - Wikipedia

    en.wikipedia.org/wiki/Outline_of_solar_energy

    Solar panel – (also solar module, photovoltaic module or photovoltaic panel) is a packaged, connected assembly of photovoltaic cells. Thin film solar cell – made by depositing one or more thin layers of photovoltaic material onto a thin substrate. Polymer solar cell – are a type of flexible solar cell.

  9. Photovoltaic module analysis techniques - Wikipedia

    en.wikipedia.org/wiki/Photovoltaic_module...

    Modern inverter or maximum power point tracker (MPPT) are able to measure the IV curve of the connected string (series circuit of multiple PV modules). [5] In a PV module under operation, the extreme conditions are open-circuit and short-circuit. At open-circuit, the voltage is maximum (open-circuit voltage V OC) and the current zero.
