- Company Profile:
The amount of electromotive force, measured in volts, that exists between two points.
Industry:Energy
A reference voltage used to describe batteries, modules, or systems (i.e., a 12-volt or 24-volt battery, module, or system).
Industry:Energy
A photovoltaic device or module that provides useful heat energy in addition to electricity.
Industry:Energy
An optical device that focuses light like a magnifying glass; concentric rings are faced at slightly different angles so that light falling on any ring is focused to the same point.
Industry:Energy
The estimated temperature of a photovoltaic module when operating under 800 w/m2 irradiance, 20�C ambient temperature and wind speed of 1 meter per second. NOCT is used to estimate the nominal operating temperature of a module in its working environment.
Industry:Energy
The length of time, under specified conditions, that a battery can be stored so that it keeps its guaranteed capacity.
Industry:Energy
The voltage at which maximum power is available from a photovoltaic module.
Industry:Energy
Negative semiconductor material in which there are more electrons than holes; current is carried through it by the flow of electrons.
Industry:Energy
A photovoltaic module, which includes optical components such as lenses (Fresnel lens) to direct and concentrate sunlight onto a solar cell of smaller area. Most concentrator arrays must directly face or track the sun. They can increase the power flux of sunlight hundreds of times.
Industry:Energy
A semiconductor produced by doping an intrinsic semiconductor with an electron-donor impurity (e.g., phosphorus in silicon).
