Principal of solar panel.

Basic principles of solar panels and 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. 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. Conversion of light energy in electrical energy is based on a phenomenon called photovoltaic effect.

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. Solar pv panels are comprised of many small photovoltaic cells photovoltaic meaning they can convert sunlight into electricity. Working principle of solar cell or photovoltaic 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.

The solar cell technology is the fastest growing power generating technology in the world. 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. Solar panel working principle a photovoltaic cell is also called a solar cell.
