Did you know that people are installing solar panels more than ever before?
In fact, according to research, the US is now installing a solar panel system every four minutes. This is a huge increase from 2006 when one was installed every 80 minutes.
With the world trying to become greener and cleaner, we need to keep up! In the future, all forms of power may be generated by these methods.
If you’re interested in protecting the environment and plan to install solar panels in your home, you need first to understand how this green form of technology works.
We will address some of the common questions, such as how do solar panels produce electricity?. This should you understand what solar panels do.
Keep reading for our simple guide on how solar panels work and how they can save you your hard earned dosh!
The Science Behind a Solar Cell
A solar cell is a small device which converts sunlight into electricity.
How does solar energy work through these cells? To put it simply, inside a solar cell there are two ultra-thin layers of silicon crystal placed on top of each other.
The top layer is specially treated so that the atoms within are unstable. This basically means it has too many electrons and would like to get rid of some. The bottom layer is specially treated to have fewer particles.
The top layer wants to get rid of electrons, and the bottom layer wants to gain electrons. For the particles to move around freely, they need to be exposed to light.
As sunlight hits the top silicon layer, the electrons are excited and flow back and forth to each layer. This reaction creates an electrical current, and the solar cell is born!
How Solar Panels Work
One solar cell on its own can only provide a minimal amount of power. But several cells connected can produce large amounts of power.
Once these cells are connected into a frame, they make a solar panel (or module). When several solar panels are connected, they become a solar array.
But how do solar panels generate electricity? When sunlight hits the solar panels, it generates DC (direct current) electricity. The problem is the electricity used in your house is AC (alternating current). This means the current from the solar panel system must go through an inverter before it can be pumped into your house.
After the DC electricity is converted to AC power through the inverter, the electrical current runs your appliances, gadgets and provides power to your electrical outlets.
Most solar panels on the market generate more than enough power to fulfill your needs. You may even have some extra surplus power that you can sell back to the grid!
Parts of a Solar Panel System
A solar panel system is made up of a solar panel, an inverter, a battery, a meter and an AC/DC switch.
The actual solar panel is attached to your roof and has the responsibility of soaking up the suns rays. This is usually composed of the individual solar cells, a frame, and a protective glass cover.
The inverter transforms the DC to AC, so you can actually use the electricity being generated.
A battery is needed to store unused power. This will allow you to have adequate power for times when there is no sunshine, such as during the night or in a blackout.
A meter, just like your mains electric meter, is designed to give you a glimpse into how your solar panels are performing. You will be able to see the DC and AC stats, the amount of energy being produced and more helpful information.
An AC/DC side isolation switch allows you to control the flow of DC and AC.
With so many promises of investment opportunities available, it’s hard to know which ones are actually legitimate. But when it comes to solar panels, they are the real deal. Installing solar panels to your home will save you money in the long run.
The cost of solar panels has dropped in price by 80% since 2008. That’s a phenomenal decrease in price.
And once the system is installed, you don’t need to worry about maintaining it overly. A yearly inspection, by your supplier, is recommended.
Additionally, you should check now and again that there aren’t any leaves or any objects blocking the panel. Apart from that, there is nothing else to do! Your solar panel system should work for at least 35 years or more.
Using the unlimited power of the sun, you can majorly reduce your electricity bills. Of course, installing solar panels is an upfront investment. But over time, by generating your own self-sufficient electricity, you can take full control of your own energy costs. And you will no longer be a victim of variable utility rates that seem to be increasing rapidly.
Some are even eligible for the Feed-in Tariff, which enables you to get paid for the green energy you produce. Yes, you can actually make money from solar panels!
One of the biggest advantages is that solar energy is clean and green.
According to the Worldwatch Institute, the number one thing we need to do to take action and go green is to save energy.
Using solar panels will reduce your carbon footprint and give you peace of mind. We all want to make the world a better place for the next generation, don’t we?
Light Up Your Life
As you can see, solar panels are a very clever way to generate power from natural resources. Not only is it green and clean, but it can even save you money in the long run.
Obviously, this is only a simplified guide to how it all works; if you want an in-depth scientific explanation, you can click here.
If you’re convinced and want to go green by powering your home with clean energy, what do you do next? You need professionals to install them. That’s where we come in!
