A photovoltaic array set in at a fixed angle with respect to horizontal.
Industry:Energy
Operating a photovoltaic array at the peak power point of the array's I-V curve where maximum power is obtained. Also called peak power tracking.
Industry:Energy
A very thin region of static electric charge along the interface of the positive and negative layers in a photovoltaic cell. The barrier inhibits the movement of electrons from one layer to the other, so that higher-energy electrons from one side diffuse preferentially through it in one direction, creating a current and thus a voltage across the cell. Also called depletion zone or space charge.
Industry:Energy
The designation of a power supply providing continuous uninterruptible service. The UPS will contain batteries.
Industry:Energy
1,000 kilowatts, or 1 million watts; standard measure of electric power plant generating capacity.
Industry:Energy
An adjustment factor used in some system sizing procedures which "allows" the battery to be gradually discharged over a 30-90 day period of poor solar insolation. This factor results in a slightly smaller photovoltaic array.
Industry:Energy
A photovoltaic (PV) array that consists of non-concentrating PV modules.
Industry:Energy
The area of immediate contact between two layers (positive and negative) of a photovoltaic cell. The junction lies at the center of the cell barrier or depletion zone.
Industry:Energy
An inverter that can function only when tied to the utility grid, and uses the prevailing line-voltage frequency on the utility line as a control parameter to ensure that the photovoltaic system's output is fully synchronized with the utility power.
