Principal Of Solar Panel

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

Principal of solar panel.

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. 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 most common type of semiconductor currently in use. This is the basic reason for producing electricity due to photovoltaic effect. How do solar panels work to generate electricity. 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.

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 pv panels are comprised of many small photovoltaic cells photovoltaic meaning they can convert sunlight into electricity. Basic principles of solar panels and power. 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.

They may or may not be backed by batteries. Solar modules are made of semiconductors that are very similar to those used to create integrated circuits for electronic equipment. An off grid solar power system is not connected to any electric grid. Conversion of light energy in electrical energy is based on a phenomenon called photovoltaic effect when semiconductor materials are exposed to light the some of the photons of light ray are absorbed by the semiconductor crystal which causes a significant number of free electrons in the crystal.
