Basic Working Principle Of Solar Panel

Working principle of solar cell.

Basic working principle of solar panel.

Solar cell any device that directly converts the energy of light into electrical energy through the photovoltaic effect. The solar cell technology is the fastest growing power generating technology. Basic principles of solar panels and power. Engineers and scientists who desire anintroduction to the field.

These solar power systems are tied with grids so that the excess required power can be accessed from the grid. They may or may not be backed by batteries. Solar panels actually comprise many smaller units. When light reaches the p n junction the light photons can easily enter in the junction through very thin p type layer the light energy in the form of photons supplies sufficient energy to the junction to create a number of electron hole pairs.

Simply put a solar panel works by allowing photons or particles of light to knock electrons free from atoms generating a flow of electricity. 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. It consists solar panel arrays storage batteries and inverter circuits. Solar panels basic principles.

It is written to address several audiences. Photovoltaic cell is the basic unit of the system where the photovoltaic effect is utilised to produce electricity from light energy. Silicon is the most widely used semiconductor material for constructing the photovoltaic cell. May 15 2018 february 24 2012 by electrical4u.

The most common type of semiconductor currently in use is made of silicon crystal. Hi friends in this article i am going to discuss about solar panel working principle and hope you will like my effort. Solar modules are made of semiconductors that are very similar to those used to create integrated circuits for electronic equipment. Silicon crystals are laminated into n type and p type layers stacked on top of each other.

This makes the system far more convenient and compact compared to thermal methods of solar energy conversion. An off grid solar power system is not connected to any electric grid. In the solar photovoltaic system solar energy is directly converted to electric power. Most of us are now aware of increasing use of solar panels however it is high time to understand solar panels basic principles and solar power to have a better idea on how to go about solar panels installation at our homes shops schools colleges institutions and commercial ventures industries.
