- Company Profile:
The length of time, under specified conditions, that a battery can be stored so that it keeps its guaranteed capacity.
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
The current flowing freely through an external circuit that has no load or resistance; the maximum current possible.
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 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
Type of a battery charge regulator where the charging current is controlled by a switch connected in parallel with the photovoltaic (PV) generator. Shorting the PV generator prevents overcharging of the battery.
