A pyrheliometer is an instrument for measurement of direct beam solar irradiance. Sunlight enters the instrument through a window and is directed onto a thermopile which converts heat to an electrical signal.
Quartz Sand – Definition, Glossary, Details – Solar Mango
Quartz sand is the raw material used to make metallurgic silicon (99% pure) through a heat reduction process. Quartz sand is the major ingredient in virtually all types of glass. And the silicon is used to manufacture solar photovoltaic cell.
Renewable Energy Certificate (REC) – Definition, Glossary, Details – Solar Mango
Renewable Energy Certificates (also called Green Tags, Renewable Energy Credits) are tradable, non tangible energy commodities that represent proof that a certain amount of electricity was generated from an eligible renewable energy resource (renewable electricity). Solar renewable energy certificates (SRECs)…
Resistive voltage drop – Definition, Glossary, Details – Solar Mango
The voltage developed across a solar cell by the current flow through the resistance of the solar cell.
Reverse Current Protection – Definition, Glossary, Details – Solar Mango
Reverse current Protection is any method of preventing unwanted current flow from the battery to the photovoltaic solar array (usually at night). It is usually done by a blocking diode.
Ribbon PV Cells – Definition, Glossary, Details – Solar Mango
Ribbon PV cells are solar cells shaped as long strips. They are produced when high temperature resistant wires are pulled through molten silicon to form a multi-crystalline ribbon of silicon crystals. The ribbon is then cut into lengths which are…
Schottky barrier – Definition, Glossary, Details – Solar Mango
A Schottky barrier is a potential energy barrier for electrons formed at a metal–semiconductor junction. Schottky barriers have rectifying characteristics, suitable for use as a diode. One of the primary characteristics of a Schottky barrier is the Schottky barrier height,…
Scribing Solar Cells – Definition, Glossary, Details – Solar Mango
Scribing is the cutting of a grid pattern of grooves in a semiconductor material generally for the purpose of marking interconnections, or to cut the solar cells into two parts. Laser scribing is done for the fabrication of monolithic cell…
Shading of solar panels – Definition, Glossary, Details – Solar Mango
Shading is a problem in PV modules caused by shadows falling on a solar panel producing power. Current drops proportionally to the reduced irradiance; shading on just one cell can reduce power output to zero.The output declines proportionally to the…
Solar Grade Silicon – Definition, Glossary, Details – Solar Mango
Solar grade silicon can be defined as silicon suitable for use in solar applications. Solar grade silicon is obtained by the Siemens process or Czochtalski Process.
