- Company Profile:
The current flowing freely through an external circuit that has no load or resistance; the maximum current possible.
Industry:Energy
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).
Industry:Energy
Silicon material that has been doped with a material that has more electrons in its atomic structure than does silicon.
Industry:Energy
An energy band in a semiconductor in which electrons can move freely in a solid, producing a net transport of charge.
Industry:Energy
A measure of the electrical resistance of a material equal to the resistance of a circuit in which the potential difference of 1 volt produces a current of 1 ampere.
Industry:Energy
A charge controller that redirects or shunts the charging current away from the battery. The controller requires a large heat sink to dissipate the current from the short-circuited photovoltaic array. Most shunt controllers are for smaller systems producing 30 amperes or less.
Industry:Energy
The material through which electricity is transmitted, such as an electrical wire, or transmission or distribution line.
Industry:Energy
Many inverters have sensing circuits that will disconnect the unit from the battery if input voltage limits are exceeded.
Industry:Energy
The maximum possible voltage across a photovoltaic cell; the voltage across the cell in sunlight when no current is flowing.
