Photovoltaic cells and solar panels.

Photovoltaics often shortened as pv gets its name from the process of converting light photons to electricity voltage which is called the photovoltaic effect. Solar panels actually comprise many smaller units. The current produced is directly dependent on how much light strikes the module. Simply put a solar panel works by allowing photons or particles of light to knock electrons free from atoms generating a flow of electricity.

The common single junction siliconsolar cell can produce a maximum open circuit voltageof approximately 0 5 to 0 6 volts. While a single photovoltaic cell is able to convert sunlight into electricity on its own the panel is essential to combine and direct the energy output of numerous cells to your inverter and home. Solar photovoltaic cells are the building blocks of solar panels and any property owner can start generating free electricity from the sun with a solar panel installation. Modules are designed to supply electricity at a certain voltage such as a common 12 volts system.

Solar photovoltaic cells are grouped in panels modules and panels can be grouped into arrays of different sizes to produce small to large amounts of electricity such as for powering water pumps for livestock water for providing electricity for homes or for utility scale electricity generation. Individual solar cell devices are often the electical building blocks of photovoltaic modules known colloquially as solar panels. When light shines on a photovoltaic pv cell it may be reflected absorbed or pass right through it. Photovoltaic cells are the main component that makes up a solar panel while solar panels are a vital component that makes up a solar system.

That makes it uniquely capable of converting light into electricity.
