What Is A Solar Panel?

A solar panel is a specialized panel to gather sunlight and generate energy. They are mainly gadgets that convert sunlight into electricity.

Called “photovoltaics” by some scientists, which means “light-electricity,” a solar panel is a series of solar cells that absorb solar rays and convert heat energy into electrical energy, making it useful to illuminate different appliances or electronic devices.

Solar panels use the Sun. The Sun is one of the most powerful and familiar energy sources right now, which generates electricity and helps plants grow, provides people with Vitamin D, and calms a stressed mind.

History of Solar Panels

History of Solar Panels

It all started in 1839 when a French physicist known as Edmond Becquerel discovered the photovoltaic effect theory, and then the development of solar energy started.

He discovered the photovoltaic effect that led to the theory of how electricity can be produced from sunlight.

In 1873, it was discovered that selenium is capable of photoconductivity. This discovery is credited to Willoughby Smith.

By 1876, Richard Evans Day and William Grylls Adams also discovered that selenium can produce energy on exposure to sunlight.

Charles Fritts further refined these discoveries and created the first solar panel from Selenium wafer which is why he is commonly referred to as the inventor of solar cells.

Many years passed in which this technology made minimal and steady steps towards advancements. On April 25th, 1954, Solar technology made a big step.

The modern solar cells are however made of silicon instead of selenium. This is why Calvin Fuller, Gerald Pearson, and Daryl Chapin are recognized as the inventors of solar cells for their invention of silicon photovoltaic cells in 1954.

In addition, as Robert Margolis said, the first invention of solar cells was hand-assembled devices.

While all the credit goes to Edmond Becquerel for the invention of the photovoltaic effect, Thanks to this technology, we can use the Sun as an alternative source, and we don’t have to use fossil fuels or oils.

The structure and development of solar panels can change from type to type.

There are two types used worldwide on roofs or ground-mounted installations in solar panels.

Crystalline Silicon Solar Panels

This type is the most common type of solar panel. Rectangular grids usually have blue or black small squares.

The solar cells in this panel are connected to a series circuit that helps the system generate more electricity.

There are also two types of crystalline silicon panels: polycrystalline and monocrystalline.

Thin-Film Solar Panels

These types of panels are primarily used in large-scale industries where larger numbers of solar panels are required on an affordable budget.

It consists of a thin layer of semiconductor material on the glass. As its name can understand it, it is fragile and flexible.

Also, there are many types of thin films: Amorphous silicon, cadmium telluride, and copper indium gallium selenide.

The module assembly is also one of the types of solar panels consisting of solar cells with a thin glass layer at the front and a protective back sheet at the back.

How Does It Work?

Usually, solar panels’ working principle is to free the electron atoms from the light particles and then generate electricity.

Rays of sunlight hit the solar cell and knock electrons away from their atoms. Conductors that are attached to the negative and positive sides of the cell develop a potential difference that generates electrical energy. This forms an electric circuit.

A solar panel contains multiple cells and multiple solar panels can be integrated together to create a solar array. The higher the number of solar panels, the greater the energy generated.

These panels are made up of many small units known as Photovoltaic cells (Photovoltaic means converting sunlight or sunlight into electricity).

These cells, sequentially connected, make a solar panel. The photovoltaic cell consists of many different layers of material, each with its purpose.

As time passes, technological advancement changes everybody’s life and makes life easier for humanity.

Solar energy, in particular, has made a lot of progress. These years, it’s much easier to buy solar panels and install them to get electricity from sunlight.

But think about how and in how many ways this energy is used. Additionally, is solar energy a perfect alternative to fossil fuels and other sources of damage to the planet’s environment?

If a short answer is given, yes, solar energy is beneficial in many ways, and yes, it is a perfect alternative source for generating electricity.

There are many benefits of using solar energy rather than fossil fuels: environmental, budget, efficiency, and many other aspects.

However, let’s look into the details. The use of solar energy is becoming more and more popular day by day.

Solar power is much cheaper than other types of electricity since it is a one-time installation only; unlike other non-renewable types, they cost quite a lot.

Since solar energy does not contain any combustion, it does not contain pollution, which does not cause greenhouse gases to be released into the environment.

It also provides a clean power source and is always available since the Sun is a renewable resource.

In fact, these solar panels use batteries to conserve energy so that they can be used on cloudy days or nights.

These panels are maintenance-free for more than thirty years, as we thought, instead of occasionally repairing and replacing electrical cables that break or melt due to electrical surges or other hazards.

As a user, you are free to pay electricity bills each month, which costs a lot of money. However, you can also save some money and maybe buy a new car.

In addition to this, solar panels provide a stylish look to your roof, which is quite fancy and stylish, and the technological development benefits it gets.


In this era, with all improvements, solar energy is used in almost every aspect of life, generating electricity for homes, industries, and many other small appliances. We can see them in practically every field.

To illustrate, watering plants has always been a problem for us. A device known as a solar pump has emerged, which brings us a new way to do more and spend less.

It is an environmentally friendly device with easy installation and zero maintenance. Another example is football is one of the most played and famous sports globally.

This sport is often done at night and requires many large lights, later known as floodlights. These projectors consume a lot of power due to the large LEDs, resulting in a high increase in the electricity bill.

Thanks to advances in solar energy, many different solar projectors have been designed for this particular purpose and to save electricity bills and provide an environmentally friendly environment.

These floodlights help store more energy than is needed only at night, thus saving the maximum amount of sunlight and converting it into electricity for use at night matches and keeping people entertained.

We can keep making examples, as it can be seen that solar energy is everywhere in our lives.

Disadvantages Of Solar Energy

Solar power doesn’t have too many disadvantages that we can bring. As mentioned above, this particular form of energy is good for our lives in almost every way.

If we should say something, we can say that the only disadvantage is that the Sun does not shine for 24 hours.

There are times when the air becomes cloudy, or its rays are heavily blocked, causing them to be unable to reach the earth, and therefore solar panels stop generating electricity.

So we can say that a user of these solar panels cannot always be dependent. Since they are quite large, they consume a lot of space to be efficient.

Of course, the Sun does not shine at night, which forces the user to purchase a large battery bank to store power for later use.

As for solar panels in cars and other automobiles, solar power is not as efficient as a vehicle using gasoline or other fossils. They do not have the same speed and power as a typical fossil or gas-powered car does.

Solar panels are undoubtedly one of the best inventions in this century. However, it is not very cost-effective due to the lack of technology.

To get your attention, there is a thousand times more solar energy coming into contact with the earth than the amount used by the world’s population.

Why Are Solar Panels Not Worth It?

With some potential, solar panels are something. They are getting lots of upgrades day by day, with many uses everywhere.

Logically, solar panels provide convenience in almost every way, but are they worth the cost?

The answer is fascinating—both yes, and no. You may wonder why. Well, all the advantages mentioned above are proof of yes.

It is environmentally friendly, eliminates the greenhouse effect, and is an excellent alternative to fossil fuels.

However, despite these advantages, the answer is no because technology may be improving every day.

There are many technological developments every day, so it creates the impression that your solar panels will be old-fashioned compared to those that produce more power and are more efficient.

Also, these panels will be installed on a large scale to power an entire house, which can cost a lot.

Besides, Most homes don’t even have a large enough roof to install these panels.

This technology can only be used by those who are financially stable and also have good monthly earnings.

Alongside the individual cost of solar panels, they come with a 30% federal tax credit.

So, indeed, these solar panels are not available or affordable for low-income people, renting or people that are trying to get a job.

Another reason why we mention these are not worth the cost and time is that a user owes twice as much because of these panels.

Another one is that You are not 100% dependent on solar panels, especially in the winter months, due to cloudy weather that prevents sunlight from reaching the earth.

It means the cloudy weather stops the electricity production of solar panels. This then leads to the use of electricity from the natural source, resulting in high electricity bills.

Of course, you can use solar panels as water pumps, calculators, etc. But it takes as much money and space to run the entire house.

Solar panels or solar parks are built for precisely this reason, so there can be a maximum number of groups mounted on the ground and illuminate large buildings or factories.

The lifespan of the solar panel is about 30 years. Don’t we personally agree that 30 years is a long time, and also, why would you want to keep a panel as old as 30 years when you see your neighbors have more advanced and more efficient panels designed for improvements?

Hence, it is costly.
