- Company Profile:
A device containing two conducting electrodes, one positive and the other negative, made of dissimilar materials (usually metals) that are immersed in a chemical solution (electrolyte) that transmits positive ions from the negative to the positive electrode and thus forms an electrical charge. One or more cells constitute a battery.
Industry:Energy
Quantum mechanical concept whereby an electron is found on the opposite side of an insulating barrier without having passed through or around the barrier.
Industry:Energy
Electromagnetic radiation in the wavelength range of 4 to 400 nanometers.
Industry:Energy
This indicates the variability in the output frequency. Some loads will switch off or not operate properly if frequency variations exceed 1%.
Industry:Energy
A solar electric or photovoltaic system that includes other sources of electricity generation, such as wind or diesel generators.
Industry:Energy
Electromagnetic radiation whose wavelengths lie in the range from 0.75 micrometer to 1000 micrometers; invisible long wavelength radiation (heat) capable of producing a thermal or photovoltaic effect, though less effective than visible light.
Industry:Energy
This is determined by the total power required by the alternating current loads and the voltage of any direct current loads. Generally, the larger the load, the higher the inverter input voltage. This keeps the current at levels where switches and other components are readily available.
Industry:Energy
A device that converts direct current electricity to alternating current either for stand-alone systems or to supply power to an electricity grid.
Industry:Energy
Placement with respect to the cardinal directions, N, S, E, W; azimuth is the measure of orientation from north.
