GLOSSARY
|
Photovolatic 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. |
Photon |
A particle of light that acts as an individual unit of energy. |
Photovolatic cell (PV) |
The smallest semiconductor element within a PV module to perform the immediate conversion of light into electrical energy. Also called a solar cell. |
Photocurrent
|
An electric current induced by radiant energy. |
megawatt-hour |
1,000 kilowatt-hours or 1 million watt-hours. |
solar energy
|
Electromagnetic energy transmitted from the sun (solar radiation). The amount that reaches the earth is equal to one billionth of total solar energy generated, or the equivalent of about 420 trillion kilowatt-hours. |
