If you have ever wondered how solar panels work, you’re not alone. It’s a complicated subject, but one that’s worth knowing. Photovoltaic cells use an electrochemical reaction between a silicon atom and sunlight to create electricity.
A Complicated Subject That is Worth Knowing
This process can be very efficient and even save you money. However, to generate electricity, the photons that strike the solar panel must first be converted to electrons.
Solar panels contain two layers of silicon. The upper n-type layer has a single electron, which is knocked out by sunlight. This electron then wanders around the top n-type layer and travels down to the bottom p-type layer, which is a more positive layer.
This free electron then travels through the conductive wires to an inverter, which turns the solar electricity into AC and then flows throughout your home.
The Main Elements of Solar Panels
The main ingredient in solar panels is silicon. It is purified and processed to create crystalline silicon. Sand is heated to approximately 3,600 degrees Fahrenheit, and the sun’s energy knocks an electron from the upper n-type layer.
The electron then travels through the conductive wires to the inverter, which converts the solar electricity to AC. This electricity then flows throughout your home. If you have a large enough panel, you can generate a large enough supply to meet your needs for years to come.
The photovoltaic cells in solar panels react to ultraviolet rays and convert them to electricity. The panels are made of conduction materials made of silicon, which is extremely reactive to solar energy.
The sun’s protons speed through space and interact with the silicon, causing electrons to escape. This electric current is then transmitted through a breaker box to your home. You’ll be amazed at how much power you can generate with a single solar panel.
The Process on How it Works
The process of how solar panels works is simple. The panels contain two layers of silicon, with silicon in between. The first layer contains n-type cells, while the lower p-type cells contain p-type cells. The sunlight hits the silicon and knocks the electron loose in the upper n-type layer.
The resulting “hole” travels downwards and a positively charged “hole” is created. The hole travels through the silicon and travels through the conductive wires to a power inverter, where the electricity is converted into AC.
The process of how solar panels work is complex but isn’t difficult to understand. When it comes to electricity, solar panels are made of two different types of silicon.
The n-type layer generates direct current (DC), while alternating current (AC) is used by most people. An inverter converts DC electricity to AC and sends it to an electrical panel, or breaker box. The breaker box distributes the electricity throughout your home.
The silicon in solar panels is the main component. The sun’s energy interacts with the atoms in the silicon, which in turn releases electrons. This process is called photovoltaic.
In simple terms, a photovoltaic cell is a solar panel that uses sunlight to generate electricity. Essentially, the panel produces electricity.
So, it’s the process of turning sunlight into electrical energy. In a perfect scenario, your PV will generate enough electricity to power your home.
It is Composed of Two Layers
A solar panel is composed of two layers. The n-type layer is the layer that collects solar energy. The p-type layer has another layer that collects sunlight. The sunlight knocks an electron out of the upper n-type layer.
This free electron travels through conductive wires to the inverter. Once the electricity passes through the inverter, it’s transformed to AC and flows throughout the home.
When the sun shines on a solar panel, the silicon will create a positive and a negative charge. When the sun hits the panel, the hole in the n-type layer will generate a negative charge and the other way around.
This is how solar panels work, but it is also the reason why they’re so effective. The sunlight you receive is the most important source of electricity, so make sure your solar panels can produce as much as possible.
