Company Profile:
The period of time, at a specified temperature, that a charged battery can be stored before its capacity falls to an unusable level.
Industry:Energy
A solar electric or photovoltaic (PV) system in which the PV array acts like a central generating plant, supplying power to the grid.
Industry:Energy
A solid-state electrical device that converts light directly into direct current electricity of voltage-current characteristics that are a function of the characteristics of the light source and the materials in and design of the device. Solar photovoltaic devices are made of various semiconductor materials including silicon, cadmium sulfide, cadmium telluride, and gallium arsenide, and in single crystalline, multicrystalline, or amorphous forms.
Industry:Energy
Same as grid-connected system.
Industry:Energy
The voltage(s) at which a charge controller will take action to protect the batteries.
Industry:Energy
Metallic contacts fused to the surface of the solar cell to provide a low resistance path for electrons to flow out to the cell interconnect wires.
Industry:Energy
The phenomenon that occurs when photons, the "particles" in a beam of light, knock electrons loose from the atoms they strike. When this property of light is combined with the properties of semiconductors, electrons flow in one direction across a junction, setting up a voltage. With the addition of circuitry, current will flow and electric power will be available.
Industry:Energy
The number of frequencies in the output waveform in addition to the primary frequency (50 or 60 Hz.). Energy in these harmonic frequencies is lost and may cause excessive heating of the load.
Industry:Energy
A feature allowing the user to adjust the voltage levels at which a charge controller will become active.
Industry:Energy
A region of electrical contact between two different materials.
