How Do Solar Pv Panels Work

Solar panels are made of a thin layer of semi conducting material sandwiched between a sheet of glass and a polymer resin.

How do solar pv panels work.

Photovoltaic cells are made of special materials called semiconductors such as silicon which is currently used most commonly. Solar panels are made out of photovoltaic cells which is why generating electricity with solar panels is also called solar pv that convert the sun s energy into electricity. Modules are designed to supply electricity at a certain voltage such as a common 12 volts system. An electric field is created when opposite charges interact similar to the poles of a magnet.

The generation of electricity is based on the creation of an electric field. Ac energy then flows through the home s electrical panel and is distributed accordingly. Solar panels are made up of hundreds of photovoltaic cells which are most often composed of silicon as the semi conductor. Basically when light strikes the cell a certain portion of it is absorbed within the semiconductor material.

Simply put a solar panel works by allowing photons or particles of light to knock electrons free from atoms generating a flow of electricity. When exposed to daylight the semi conducting material becomes energised and this produces electricity. There are many photovoltaic cells within a single solar panel and the current created by all of the cells together adds up to enough electricity to help power your home. Photovoltaic cells are sandwiched between layers of semi conducting materials such as silicone.

Solar panels work by absorbing sunlight with photovoltaic cells generating direct current dc energy and then converting it to usable alternating current ac energy with the help of inverter technology. A number of solar cells electrically connected to each other and mounted in a support structure or frame is called a photovoltaic module. Solar photovoltaic pv panels are based on a high tech but remarkably simple technology that converts sunlight directly to electricity. It s an idea that has been around for well over a century.

Solar pv cells generate electricity by absorbing sunlight and using that light energy to create an electrical current. The current produced is directly dependent on how much light strikes the module.
