Have you ever asked yourself how solar panels work? Solar energy is the energy springing from sunlight that has been converted into energy useful to us humans. Solar power can be used to heat our homes, to small power appliances, to water swimming pools, and even to run our cars. There are many different places solar power can be applied, from rural areas to large cities. Let’s take a look at how solar panels work.
The sun provides us with countless numbers of different types of renewable energy. It is responsible for renewing the oxygen in our atmosphere, converting light into other forms of energy we use every day, and is responsible for heating our earth’s surface. Solar power is a valuable source of renewable energy because it has no pollution associated with it. Solar energy can also be used to heat our homes, to small power appliances, and to power our cars. All of these things can provide electricity for a much smaller home and maintain the lights on at the International Space Station.
How Do Solar Panels Work?
Photovoltaic cells (PV) make up the heart of a solar panels system. The cells consist of stacks of cells made from two different types of material. One type is made of crystalline silicon (CS) layer, and the other type is made of non-crystalline silicon (NSC) layer. A special chemical reaction takes place when the two different types of materials come into contact with each other. This chemical reaction creates electric charges, which are then linked together using what are called “bridges.”
When two layers of crystalline silicon meet, they form an insulating barrier. This layer stops electric fields from flowing freely through the crystalline silicon, which allows some energy to enter the system. When an electric current is sent through this barrier, it comes out as an electrical pulse. This electrical pulse is in the form of a direct current or DC energy. To convert the DC energy into usable energy, photovoltaic cells need to be connected to an energy receiving device such as a solar panel.
A Much Ado
To understand how solar panels work, it is important to understand how electricity is sent and received by a home. In the home, electricity flows from an electric generator or battery, which creates a direct current or DC energy. This energy then travels through wiring that is connected to solar cells. These solar cells absorb photons (light energy) from the sun and change them into direct current energy. This is then stored in the solar batteries.
The current from the direct current is routed through what are called “bindings.” Bindings are where extra electrons are gained so that the total number of electrons is greater than the number of electrons that enter the solar cells. At this point, the electrons are labeled with an “identity” so that they can be reabsorbed into the solar panels. The entire process is called “photovoltaic conversion.”
The question “How do solar panels work” can now be answered in another simple way: The light energy that the sun emits can be changed into a form that can be easily converted into useful electricity. The sun is a completely natural source of energy. The sun can supply us with enough energy for our entire life on earth; however, in order to do so, we must use solar cells. These special solar cells can absorb light energy from the sun and change it into direct current energy, which the solar panel system uses to power our homes.
Now that you have learned how do solar panels work, you may be wondering if they truly do “solve the energy crisis.” The simple truth is that the answer is no; however, they can dramatically reduce your electric bill by making use of clean and efficient photovoltaic cells. In addition to this, they can add to the beauty of your home by creating an electric current that makes your home look more beautiful than ever before.
