Basic Working Principle Of Solar Panel

Photovoltaic cell is the basic unit of the system where the photovoltaic effect is utilised to produce electricity from light energy.

Basic working principle of solar panel.

These cells convert sunlight to energy by the photovoltaic effect we will discuss this effect in detail in a later article. Solar panels or modules are designed to supply electric power at a certain voltage say 12v but the current they produce is directly dependent on the incident light. It is written to address several audiences. But for most of the times we require ac power and hence solar power system consists of an inverter too.

The cube shaped casting is then cut into ingots and then sliced into very thin wafers. Solar cells basic principles solar panel is made of several photo voltaic cells. The solar cells are very thin about 1 100th of an inch thick and usually 3 to 4 inches square. Processing wafers silicon atoms have four arms under stable conditions they become perfect insulators.

These solar cells convert sunlight in to energy by the photo voltaic effect. They are available in different sizes and different price ranges. The silicon atom has four valence electrons. Basic photovoltaic principles and me1hods seri sp 290 1448 solar information module 6213 published february 1982 this book presents a nonmathematical explanation of the theory and design of pv solar cells and systems.

Because they have no moving parts that could need maintenance or fuels that would require replenishment solar cells provide power for most space installations from communications and weather satellites to space stations. 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 cells are very thin about 1 100th of an inch thick and usually 3 to 4 inches square. A solar panel is made of several photovoltaic cells.

Engineers and scientists who desire anintroduction to the field. A solar cell works in three steps. Silicon is the most widely used semiconductor material for constructing the photovoltaic cell. It is a semiconductor device which converts sunlight into dc power using the photoelectric effect.

As of now it is clear that photovoltaic modules produce dc electricity. Solar panels actually comprise many smaller units. High purity silicon crystals are used to manufacture solar cells. Practically all solar cells are photodiodes made of semiconductor material like silicon.
