Terminology
Solar Photovoltaic (Solar PV):
Process or technology that
converts sunlight into electricity.
Solar Cell: The device that
converts sunlight into electricity.
Also called a photovoltaic cell.

4. PVA FOR SOLAR APPLICATIONS
Solar Module or PV Module: An
interconnected array of solar cells in a
package suitable for the end use application.
Grid Parity: The point at which electricity
produced by solar PV is equal to or cheaper than
grid Power.
BIPV: Building Integrated Photovoltaics.
Solar PV cells & modules that are
integrated into building materials or
components. Examples would be roofing
tiles, spandrel areas on building cladding,
awnings, and skylights.
