Principle Of Solar Panel

Solar cell any device that directly converts the energy of light into electrical energy through the photovoltaic effect.

Principle of solar panel. 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. They may or may not be backed by batteries. How do solar panels work to generate electricity. Solar panel working principle a photovoltaic cell is also called a solar cell.

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. Solar modules are made of semiconductors that are very similar to those used to create integrated circuits for electronic equipment. Solar panels basic principles. The solar cell technology is the fastest growing power generating technology in the world.

The most common type of semiconductor currently in use. An off grid solar power system is not connected to any electric grid. These solar power systems are tied with grids so that the excess required power can be accessed from the grid. 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.

The other components of the system convert the. It consists solar panel arrays storage batteries and inverter circuits. 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. Solar panels are in turn combined to form solar arrays.

Solar cell multicrystalline silicon photovoltaic modules commonly called solar modules are the key components used to convert sunlight into electricity. It is due to fact that the solar cells with conversion efficiency of more than 40 are becoming available.
