How Do Solar Pv Panels Work

An electric field is created when opposite charges interact similar to the poles of a magnet.

How do solar pv panels work.

Solar photovoltaic pv panels are based on a high tech but remarkably simple technology that converts sunlight directly to electricity. Basically when light strikes the cell a certain portion of it is absorbed within the semiconductor material. Solar panels actually comprise many smaller units. The generation of electricity is based on the creation of an electric field.

Solar panels are made up of hundreds of photovoltaic cells which are most often composed of silicon as the semi conductor. Modules are designed to supply electricity at a certain voltage such as a common 12 volts system. The current produced is directly dependent on how much light strikes the module. Solar pv cells generate electricity by absorbing sunlight and using that light energy to create an electrical current.

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. 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. 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. In 1839 french scientist edmond becquerel discovered that certain materials would give off sparks of electricity when struck with sunlight.

Photovoltaic cells are made of special materials called semiconductors such as silicon which is currently used most commonly. Solar panels are made of a thin layer of semi conducting material sandwiched between a sheet of glass and a polymer resin. It s an idea that has been around for well over a century. Photovoltaic cells are sandwiched between layers of semi conducting materials such as silicone.

When exposed to daylight the semi conducting material becomes energised and this produces electricity. Ac energy then flows through the home s electrical panel and is distributed accordingly.
