Solar power is a form of energy that comes from the sun in the form of radiation. To receive this radiation, solar panels are used, which absorb sunlight and turn it into electricity.
Since this process needs light from the sun, it can only provide electricity during daylight hours, but exceptions include when the sky is overcast.
How Do Solar Panels Work?
According to a Solar Energy Industries Association (SEIA) report, the US installed 5.7 gigawatts (GWdc) of solar PV capacity in the second quarter of 2021.
Solar cells can create electricity because they are made from a semiconductor material that has been ‘doped’ with the two types of impurities called N-type and P-type.
When sunlight hits the cell, it excites the electrons in these regions, giving them enough energy to escape their bonds. These free electrons move out of the cell and get collected by an external circuit carrying them to a power supply converted into electricity.
This process is called the photoelectric effect, which can be witnessed in certain metals like zinc, selenium, and cadmium when exposed to light.
Benefits of Installing Solar Panels
Some companies even come out and install the solar system with no money down, which means you can start seeing savings immediately after it is installed.
They offer benefits like:
Savings on Electricity Bills
A major benefit of using solar panels for electricity is that electricity costs are free except for the installation and maintenance fees. Since solar cells are independent of any electric company, you won’t have to pay anyone for this electricity. This is the prime reason why solar energy is in demand in the market.
Durable and Long-lasting
Solar panels are durable and last for decades, so you won’t have to worry about replacing them. Some solar panels don’t even require your attention as they contain self-contained power systems that automatically track the sun’s movement from east to west during daylight hours.
Additionally, if you need to move these cells, it will be as easy as taking them out and turning them around to face the sun.
It means that even if the day’s solar energy isn’t perfect for your location, you can at least get a few hours of power from one side during midday while still getting electricity from the opposite side in the evening.
The most significant benefit is that they are very affordable, which means you can start seeing savings almost immediately after installation.
If you need to purchase these cells for your home or business, it will be cheaper because there won’t be any electricity bills to pay, making the solar panels even more cost-effective.
These solar panels are different from other energy sources because they don’t require an electric company to create energy. It means you won’t have to worry about depending upon a service provider for your electricity. You can enjoy the independence of being your own electricity supplier and managing how the power works and is distributed across the space.
Convenient and Portable
The best thing about solar cells is that they are effortless to install, which means you can move them around as much as you want without any problems.
For instance, if your business moves to another location or needs more electricity for another room in your house, it will be simple to adjust the panels around without worrying about losing power because there is always sunlight.
Furthermore, since solar panels use natural sunlight to create energy, there are no harmful emissions in the environment. It is one of the main reasons why more and more people are using solar cells, as it helps contribute to environmental conservation to some extent.
