A way of joining solar cells or photovoltaic modules by connecting positive leads together and negative leads together; such a configuration increases the current, but not the voltage.
_:
Peak Watt
The amount of power a photovoltaic module will produce at standard test conditions (normally 1000 W/m2 and 25° cell temperature).
_:
Photovoltaic Array
An interconnected system of PV modules that function as a single electricity-producing unit. The modules are assembled as a discrete structure, with common support or mounting. In smaller systems, an array can consist of a single module.
_:
Photovoltaic Cell
The smallest semiconductor element within a PV module to perform the immediate conversion of light into electrical energy.
_:
Photovoltaic Conversion Efficiency
The ratio of the electric power produced by a photovoltaic device to the power of the sunlight incident on the device.
_:
Photovoltaic Generator
The total of all PV strings of a PV power supply system, which are electrically interconnected.
_:
Photovoltaic Module
The smallest environmentally protected, essentially planar assembly of solar cells and ancillary parts, such as interconnections, terminals, [and protective devices such as diodes] intended to generate direct current power under unconcentrated sunlight. The structural (load carrying) member of a module can either be the top layer (superstrate) or the back layer (substrate).
_:
Photovoltaic System
An installation of PV modules and other components designed to produce power from sunlight and meet the power demand for a designated load.
_:
Photovoltaic(s)
Pertaining to the direct conversion of light into electricity.
