Pyranometer

A pyranometer is a type of actinometer used for measuring solar irradiance on a planar surface and it is designed to measure the solar radiation flux density (W/m2) from the hemisphere above within a wavelength range 0.3 μm to 3 μm. The name pyranometer stems from the Greek words πῦρ (pyr), meaning “fire”, and ἄνω […]

Selenium is a chemical element with symbol Se and atomic number 34. It is a nonmetal with properties that are intermediate between the elements above and below in the periodic table, sulfur and tellurium. It rarely occurs in its elemental state or as pure ore compounds in the Earth’s crust. Selenium was discovered in 1817 by […]

Charles Fritts (1850 – 1903[1]) was the American inventor credited with creating the first working Selenium Cell in 1883. The world’s first rooftop solar array, using Fritts’ selenium cells, was installed in 1884 on a New York City rooftop.

Leonardo di ser Piero da Vinci , more commonly Leonardo da Vinci or simply Leonardo, was an Italian Renaissance polymath whose areas of interest included invention, painting, sculpting, architecture, science, music, mathematics, engineering, literature, anatomy, geology, astronomy, botany, writing, history, and cartography. He has been variously called the father of palaeontology, ichnology, and architecture, and […]

John Ericsson (born Johan) (July 31, 1803 – March 8, 1889) was a Swedish-American inventor, active in England and the United States, and regarded as one of the most influential mechanical engineers ever. Ericsson collaborated on the design of the steam locomotive Novelty, which competed in the Rainhill Trials on the Liverpool and Manchester Railway, […]

The photoelectric effect is the emission of electrons or other free carriers when light is shone onto a material. Electrons emitted in this manner can be called photo electrons. The phenomenon is commonly studied in electronic physics, as well as in fields of chemistry, such as quantum chemistry or electrochemistry. In 1905, Albert Einstein published […]

Inverter Output Circuit. Conductors between the inverter and an ac panelboard for stand-alone systems or the conductors between the inverter and the service equipment or another electric power production source, such as a utility, for electrical production and distribution network.

Inverter Input Circuit is defined as conductors between the inverter and the battery in stand-alone systems or the conductors between the inverter and the photovoltaic output circuits for electrical production and distribution network.

Photovoltaic Output Circuit is defined as the circuit conductors between the photovoltaic source circuit(s) and the inverter or dc utilization equipment.

Photovoltaic Source Circuit is defined as the circuits between modules and from modules to the common connection point(s) of the dc system.
