How Does Solar Panels Work?
As the world is moving forward with new technologies, we are finally realizing the importance of renewable sources of energy. And the technology that shows exceptional potential is the harnessing power of the sun, i.e., solar energy. Solar panels are the fundamental units that harvest solar energy and convert them into electricity. In this article, we will discuss how solar panels work.
What are Solar Panels?
Solar panels, also known as Photovoltaic (PV) panels, are devices that generate electricity from photons, which are a stream of light particles that come from the sun. The basic principle behind the working of solar panels is the photoelectric effect, which means that when photons hit the silicon present in the solar panel, they knock the electrons loose, which generates electricity. .
The Working of Solar Panels.
Solar panels are made up of multiple photovoltaic cells that work cooperatively to generate electricity. These photovoltaic cells are connected with each other in a series using conductive wires, which makes the electricity flow. Here's how the electricity generation process looks like:
1. Absorption of Sunlight: When sunlight hits the surface of the solar panel, it penetrates the protective coating and encounters the cells' silicon layer. Once the photon hits the silicon atoms, electrons get excited and leave their atoms to become free electrons.
2. Generation of Electric Circuit: There is a p-type layer and an n-type layer of silicon in each solar cell. Due to the junction present between these two layers, a built-in electric field is generated. This electric field causes the free electrons to move towards the p-side and the holes towards the n-side, causing a separation in charge.
3. Conversion of Electric Energy: The separated electrons then move to the opposite terminal via an external circuit, generating an electric current, which can be used in powering a home or transferred to the electrical grid.
4. Return of Electrons to the Negative Terminal: After the electrons pass through the load, they return to the negative terminal, closing the circuit.
This completes the electricity generation process and enables solar panels to produce electricity.
Why Should You Invest in Solar Panels?
There are many benefits of investing in solar panels, some of which are listed below:
1. Cost-effective: Solar panels are a one-time investment that can help you save money on your electricity bills in the long run.
2. Efficiency: Solar panels have an efficiency level of around 20%, with some higher-end models producing an efficiency level of 22%. Moreover, the efficiency level of solar panels is consistently increasing with advancements in technology.
3. Environmentally friendly: Since solar panels rely solely on the sun's energy, they are an eco-friendly alternative to traditional sources of electricity.
4. Maintenance: Solar Panels are durable and require very little maintenance, making them an ideal choice for those looking for renewable sources of energy.
In Conclusion.
Today, solar energy is one of the most promising technologies that offer us a way to shift from non-renewable sources of energy to renewable sources. Solar panels present an eco-friendly alternative to conventional electricity, and investing in them has amazing benefits.
