Working Principle Of A Solar Panel

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.

Working principle of a solar panel.

This makes the system far more convenient and compact compared to thermal methods of solar energy conversion. Solar cell any device that directly converts the energy of light into electrical energy through the photovoltaic effect. Engineers and scientists who desire anintroduction to the field. Since a solar cell only generates about 1 2 watts of power it is necessary to combine them into solar power panels in order to generate more power.

Simply put a solar panel works by allowing photons or particles of light to knock electrons free from atoms generating a flow of electricity. Solar cell is a device or a structure that converts the solar energy i e. The solar cell technology is the fastest growing power generating technology. These solar panels and arrays are the key component of all residential solar energy systems.

They may or may not be backed by batteries. A standard solar panel also known as a solar module consists of a layer of silicon cells a metal frame a glass casing and various wiring to allow current to flow from the silicon cells silicon atomic 14 on the periodic table is a nonmetal with conductive properties that allow it to absorb and convert sunlight into electricity. Hi friends in this article i am going to discuss about solar panel working principle and hope you will like my effort. How do solar panels work to generate electricity.

While n type semiconductor and p type semiconductor contact each other the free electrons near to the contact surface of n type semiconductor get plenty of adjacent holes of p type material. This potential barrier is essential for working of a photovoltaic or solar cell. Solar panels actually comprise many smaller units. In the solar photovoltaic system solar energy is directly converted to electric power.

These solar power systems are tied with grids so that the excess required power can be accessed from the grid. The majority of solar cells are fabricated from silicon with increasing efficiency and lowering cost as the materials range from amorphous to polycrystalline to crystalline silicon forms. There is always a potential barrier between n type and p type material. The other components of the system convert the.

An off grid solar power system is not connected to any electric grid. The energy obtained from the sun directly into the electrical energy. Solar panels are in turn combined to form solar arrays. It is written to address several audiences.

It consists solar panel arrays storage batteries and inverter circuits. 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.
