Principal Of Solar Panel

A solar cell is a solid state electrical device p n junction that converts the energy of light directly into electricity dc using the photovoltaic effect the process of conversion first requires a material which absorbs the solar energy photon and then raises an electron to a higher energy state and then the flow of this high energy electron to an external circuit.

May 15 2018 february 24 2012 by electrical4u. Basic principles of solar panels and power. Solar pv panels are comprised of many small photovoltaic cells photovoltaic meaning they can convert sunlight into electricity. Solar power and solar panels are getting a lot of attention as part of the solution to our energy crisis solar energy also called photovoltaic energy is undergoing rapid changes thanks to massive investment in research and development.

It is due to fact that the solar cells with conversion efficiency of more than 40 are becoming available. The solar cell technology is the fastest growing power generating technology in the world. 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 cell any device that directly converts the energy of light into electrical energy through the photovoltaic effect.

Solar panels basic principles. Conversion of light energy in electrical energy is based on a phenomenon called photovoltaic effect. These cells are made of semi conductive materials most often silicon a material that can conduct electricity while maintaining the electrical imbalance needed to create an electric field.
