Light coming from the sun is composed of energy particles called ‘photons’. Solar cells (also known as photovoltaic cells) use this light to produce electricity or heat.

A collection of solar cells mounted on a structure is known as a solar panel.

There are mainly three types of solar panels:

  1. Mono crystalline
  2. Poly crystalline
  3. Thin-film solar panels

How Do Solar Panels Work?

The solar panel is made up of photovoltaic cells containing layers of silicon, boron, and phosphorus. When the sunbeam hits the surface of the panel, photons in these cells move electrons. This is called the photovoltaic effect.

Electrons gather on conductive plates and change into power which then streams to the battery.

Other natural resources can become limited but sunlight is always available in vast amounts. Solar panels could potentially meet all future energy needs and will soon be a trend everywhere.

What are the disadvantages and advantages of solar panels?

The number of homeowners opting for solar energy is increasing every day. Probably the greatest advantage for property holders considering a change to solar panels is the month-to-month reserve funds on utilities. For sure, that is an incredible benefit of running your home on solar power.

But do you know that you can help the environment enormously by switching to solar power?

Here, we explain some of the prominent solar panel pros and cons to help you make a final decision.

Advantages of Solar Energy

There are many advantages of solar energy. Some are as follows:

Unlimited Source:

A major pro of solar panels is that solar energy is accessible consistently. We can’t run out of sun-based energy compared to other natural resources.

Solar energy will be open as long as we have the sun, consequently, daylight will be accessible to us until the sun dies.

Reduce expenses:

It can decrease your overall expenses as you don’t have to pay house electricity bills. Solar panels are literally an investment as it lasts up to 25 years and the panel will have totally paid for itself by giving free power to your home in a few years. After that, you’ll start to bring in cash by basically doing nothing other than having solar panels installed and selling excess solar energy to the grid.

On top of these benefits, solar panels add value to your property by making it more expensive because now future owners don’t have to pay electricity bills.

Eco friendly:

Production of electricity using fossils results in the formation of harmful gasses which increases air pollution. These gases also cause greenhouse effects and drastic weather changes. Solar panel technology doesn’t cause any toxic emissions. Solar panel efficiency and eco-friendly nature is the most prominent reason for it trending more now.

Multiple uses:

In addition to generating electricity, solar panels can also benefit us in other purposes, such as generating heat, powering satellites in space, and purifying water.

Norwich is very famous for using solar panels. Nowadays, solar panels in Norwich are also used with other materials in the construction of buildings like solar energy windows.


Solar panels are very tough and can withstand even cruel climate conditions. They work anyplace and in any environment on Earth assuming even a small measure of daylight hits the board.

Solar panels don’t need much repair. Cleaning them a few times each year will do the work and also many solar panel manufacturing companies provide a warranty for some years.

Disadvantages of Solar Energy

Some disadvantages of solar energy are as follows:


Installing solar panels can be expensive but as mentioned above it’s an investment that must be made very carefully. Some governments are trying to introduce solar panel schemes which make buying solar panels easy. Some panels take a lot of space. There needs to be a lot of work done to make solar panels an easy option for everyone.

Sun dependent:

As solar panels are dependent on sunlight, they don’t work at night or in the dark. So you need to have a backup plan for the night. Also on rainy and cloudy days, the efficiency of solar panels is reduced somehow which makes them weather dependent to some extent too.

Not for everyone:

Solar can’t work for everyone. People living in rented houses can’t afford to install solar as they have to move from the house once their contract ends with the owner. Shifting solar is very costly and also not possible easily as solar can’t fit the same on all kinds of roofs. In some houses, solar can’t even be installed due to their roof orientation with the sun.

Environmental hazard:

Solar energy doesn’t cause more harmful environmental effects than other alternatives but it still has some negative effects. Toxic materials and synthetic compounds are utilized in the production of panel systems. Some solar systems also use unsafe liquids, the leakage of which can be very harmful to the environment. If these materials are not disposed of properly, they can cause significant damage to the environment.


Every system has its flaws, so do the solar panels. But solar energy offers significantly more benefits than the downside. Clearly, its pros outweigh its cons as it is the least damaging method to produce electricity.
