- Company Profile:
A PV array or module that consists of nonconcentrating elements. Flat-plate arrays and modules use direct and diffuse sunlight, but if the array is fixed in position, some portion of the direct sunlight is lost because of oblique sun-angles in relation to the array.
Industry:Energy
The energy of an electron at rest in empty space; used as a reference level in energy band diagrams.
Industry:Energy
The voltage required to counteract the self-discharge of the battery at a certain temperature.
Industry:Energy
The highest energy band in a semiconductor that can be filled with electrons.
Industry:Energy
The number of years that a battery can keep its stated capacity when it is kept at float charge.
Industry:Energy
Energy content of an electron in orbit about an atomic nucleus. Also called bound state.
Industry:Energy
A battery operation in which the battery is normally connected to an external current source; for instance, a battery charger which supplies the battery load< under normal conditions, while also providing enough energy input to the battery to make up for its internal quiescent losses, thus keeping the battery always up to full power and ready for service.
Industry:Energy
A voltage-dependent variable resistor. Normally used to protect sensitive equipment from power spikes or lightning strikes by shunting the energy to ground.
Industry:Energy
In reference to solar photovoltaic cell manufacture, a method of growing a large-size, high-quality crystal whereby coils heat a polycrystalline ingot placed atop a single-crystal seed. As the coils are slowly raised the molten interface beneath the coils becomes a single crystal.
Industry:Energy
A battery designed with a vent mechanism to expel gases generated during charging.
