What is a photovoltaic system?
Photovoltaics (PV): Devices that convert solar energy into electricity using semiconductors (this conversion is called the photovoltaic effect). Solar panels are photovoltaics and make up a PV system. Power output/rating: The number of watts a solar panel produces in ideal conditions.
What is a photovoltaic (PV) cell?
A photovoltaic (PV) cell, commonly called a solar cell, is a nonmechanical device that converts sunlight directly into electricity. Some PV cells can convert artificial light into electricity. Sunlight is composed of photons, or particles of solar energy.
What is a PV panel?
PV cells are electrically connected in a packaged, weather-tight PV panel (sometimes called a module). PV panels vary in size and in the amount of electricity they can produce. Electricity-generating capacity for PV panels increases with the number of cells in the panel or in the surface area of the panel.
