P
Parabolic dish
A high-temperature (above 180 degrees Fahrenheit) solar thermal concentrator, generally bowl-shaped, used to collect or distribute energy.
Photovoltaic (PV) array
An interconnected system of PV modules that function as a single electricity-producing unit.
Photovoltaic (PV) cell
The smallest semiconductor element within a PV module to convert light into electrical energy. Also called a solar cell.
Photovoltaic (PV) module
The smallest complete environmentally protected assembly of interconnected PV cells. PV modules are generally installed in a frame on a rooftop or on a support mount. The most common type of PV module is a solar panel.
Photovoltaics (PV)
