A solar panel (photovoltaic module or photovoltaic panel) is a packaged interconnected
assembly of solar cells, also known as photovoltaic cells. The solar panel can be
used as a component of a larger photovoltaic system to generate and supply electricity
in commercial and residential applications.
Because a single solar panel can only produce a limited amount of power, many
installations contain several panels. This is known as a photovoltaic array or PVA.
A photovoltaic installation typically includes an array of solar panels, an inverter,
batteries and interconnection wiring.
