- Company Profile:
Energy level at which the probability of finding an electron is one-half. In a metal, the Fermi level is very near the top of the filled levels in the partially filled valence band. In a semiconductor, the Fermi level is in the band gap.
Industry:Energy
May be used for photovoltaic array wiring if sunlight resistant coating is specified; can be used for interconnecting balance-of-system components but not recommended for use within battery enclosures.
Industry:Energy
The ratio of a photovoltaic cell's actual power to its power if both current and voltage were at their maxima. A key characteristic in evaluating cell performance.
Industry:Energy
May be used within battery enclosures and for interconnecting balance-of-systems.
Industry:Energy
A photovoltaic array set in at a fixed angle with respect to horizontal.
Industry:Energy
The designation of a power supply providing continuous uninterruptible service. The UPS will contain batteries.
Industry:Energy
A photovoltaic (PV) array that consists of non-concentrating PV modules.
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.
Industry:Energy
An arrangement of photovoltaic cells or material mounted on a rigid flat surface with the cells exposed freely to incoming sunlight.
Industry:Energy
The deposition of thin films of semiconductor material by the evaporation of elemental sources in a vacuum.
