Infrared radiation (IR) or the term infrared alone refers to energy in the region of the electromagnetic radiation spectrum at wavelengths longer than those of visible light,but shorter than those of radio waves.

Intrinsic semiconductor is also known as I type semiconductor. Instrinsic semiconductor is a pure semiconductor to which no impurities have been added and in which electrons and hole densities are equal at thermal equilibrium.

If a part of the solar cell is shaded the cell can heat up to such extreme temperatures that the cell material as well as the encapsulation (EVA) and backsheet will be permanently damaged. This fault is called hotspot.

High Voltage Disconnect is used to ensure that an electrical circuit is completely de-energised for service or maintenance. Such switches are often found in electrical distribution and industrial applications, where machinery must have its source of driving power removed for…

A heterojunction is the interface that occurs between two layers or regions of dissimilar crystalline semiconductors. These semiconducting materials have unequal band gaps as opposed to a homojunction. Silicon heterojunction technology (Si-HJT) is a popular topic in crystalline silicon photovoltaic…

An electrical grid is an interconnected network for delivering electricity from suppliers to consumers. It consists of solar generating stations that produce electrical power, high-voltage transmission lines that carry power from distant sources to demand centers, and distribution lines that…

Solar Glass/Glass Laminate are used to seal the solar modules and must have properties like high solar energy transmittance, strength and durability, as well as additional functionalities like transparent conductive oxide coatings, anti-reflective coatings and sodium barrier layers. It is…

Gigawatt is a unit of measurement of power typically used to estimate the power produced by large power plants or even to represent power capacity of countries. The total installed capacity of renewable energy systems such as wind and solar…

The amount of power density in sunlight received at the earth’s surface at noon on a clear day (about 1,000 Watts/square meter).

Float charge is the voltage required to counteract the self-discharge of the battery at a certain temperature. A float charger will charge a battery at a similar rate as a battery self-discharges, thus maintaining a full capacity battery
