I was learning about solar panels, a couple of months ago and there is a lot of stuff to it. So I decided to research more on it and write a helpful post on solar panels and their working.
Solar panels are composed of different small units that are known as photovoltaic cells. The photovoltaic cells are capable of converting sunlight to electricity.
In this article, we will discuss solar panels, what are they, how do they work, and how they generate electricity. So, stay tuned.
What Is A Solar Panel System?
A solar panel system brings energy directly from the sun. Solar Panel Systems are widely recognized as PV panels that convert light from the sun.
The light energy from the sun contains small particles known as photons that are used to power the electrical loads.
What is the purpose of a Solar Panel?
The sole purpose of solar panels is to generate electricity by the phenomena of allowing light rays from son to knock off their electrons from their atom shells.
The main focus of solar panels is nothing much complicated. They only absorb the light rays from the sun and convert the photons (particles) into other forms of energy.
The other energy forms are heat and electricity.
Types of Solar Panels
There are three major types of solar panels, which are listed below:
- Poly Crystalline
- Thin-Film Amorphous
How do Solar Panels Work?
The working procedure of a solar panel is much easy to understand. A solar panel works by allowing the particles of light to free their electrons from their atom shells.
In this way, the flow of electricity is produced.
As mentioned above, a solar panel is composed of photovoltaic cells. All of the cells are linked together strongly. Hence they make up a solar panel.
What is a photovoltaic cell?
A photovoltaic cell is constructed of two slices of semiconducting materials, that are usually made up of silicon.
The photovoltaic cells establish an electric field that is much similar to a magnetic field.
A magnetic field occurs due to the presence of opposite poles, while an electric field is created when the charges get separated.
To get an electric field the constructors of solar panels opiate silicon with other useful materials.
In this way, each slice of photovoltaic cells attains a positive and a negative charge.
They also add a bit phosphorus in the top layer of silicon. By using phosphorus solar panels grab an extra amount of electrons having a negative charge.
The bottom layer is treated with boron giving an output of less positive and negative charges (electrons).
All of this procedure creates an electric field at the junction between the silicon layers.
After setting up the procedure mentioned above, the next step is to use other components that can turn the electrons into a stable power to use.
The metal conductive plates located on the sides of a cell are used to collect the electrons. They transfer the negatively charged particles to the wires.
Resulting in a smooth flow of electrons just like a source of electricity.
This is how a solar panel works! I hope you will understand this working procedure.
