Principle Of Solar Panel

How do solar panels work to generate electricity.

Principle of solar panel.

It is due to fact that the solar cells with conversion efficiency of more than 40 are becoming available. These solar power systems are tied with grids so that the excess required power can be accessed from the grid. 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.

The most common type of semiconductor currently in use. Solar modules are made of semiconductors that are very similar to those used to create integrated circuits for electronic equipment. 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. The solar cell technology is the fastest growing power generating technology in the world.

Solar cell multicrystalline silicon photovoltaic modules commonly called solar modules are the key components used to convert sunlight into electricity. They may or may not be backed by batteries. Solar panel working principle a photovoltaic cell is also called a solar cell. Solar cell any device that directly converts the energy of light into electrical energy through the photovoltaic effect.

Solar panels are in turn combined to form solar arrays. 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. These solar panels and arrays are the key component of all residential solar energy systems. 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.
