Company Profile:
A device that converts alternating current to direct current. See inverter.
Industry:Energy
A term for the design and integration of photovoltaic (PV) technology into the building envelope, typically replacing conventional building materials. This integration may be in vertical facades, replacing view glass, spandrel glass, or other facade material; into semitransparent skylight systems; into roofing systems, replacing traditional roofing materials; into shading "eyebrows" over windows; or other building envelope systems.
Industry:Energy
Prevents overcharging of batteries by controlling charge cycle-usually adjustable to conform to specific battery needs.
Industry:Energy
A semiconductor connected in series with a solar cell or cells and a storage battery to keep the battery from discharging through the cell when there is no output, or low output, from the solar cell. It can be thought of as a one-way valve that allows electrons to flow forwards, but not backwards.
Industry:Energy
See stand-alone systems.
Industry:Energy
The chemical element commonly used as the dopant in photovoltaic device or cell material.
Industry:Energy
The amount of generating capacity a central power system must maintain to meet peak loads.
Industry:Energy
A sausage-shaped, synthetic single-crystal mass grown in a special furnace, pulled and turned at a rate necessary to maintain the single-crystal structure during growth.
Industry:Energy
The property of a conductor, which opposes the flow of an electric current resulting in the generation of heat in the conducting material. The measure of the resistance of a given conductor is the electromotive force needed for a unit current flow. The unit of resistance is ohms.
Industry:Energy
The amount of heat required to raise the temperature of one pound of water one degree Fahrenheit; equal to 252 calories.
