The Pros and Cons of Solar Energy

As the world is moving ahead with new heavy-duty technology, and the development of new facilities, the pollution quotient of the world is also increasing. This is a worrying sign, because not only the environment is polluted in several ways, the non-renewable sources of energy are also being depleted at a faster rate.

The rate at which these resources are being used, there would come a scarcity of energy sources if humans don’t shift to a renewable source of energy that is clean, as well as eco-friendly. It is very evident that fossil fuels may not be non-renewable, but certainly, they are replenishable. It takes thousand years for them to be converted to oils and fuels. However, using these fuels causes a huge amount of pollution to the environment. And the imminent threat that could be a cause of human loss could well be pollution and not scarcity of resources.

It is a clean renewable source of energy that does not pollute the environment. In this article, we are going to learn about the solar energy pros and cons. And how we can use solar energy for our benefit.

What is solar energy?

In all the façade for depleting resources and pollution, solar energy stands as a possible solution to several problems and there are several benefits of solar energy as well. The Sun is indeed an enormously strong source of energy, therefore sunlight seems to be the most significant source of energy received by Earth, although its strength at the surface of the planet is rather modest. This is mostly due to the massive radial dispersion of sunlight because of the distance.

The Earth’s atmosphere including clouds intercepts or scatter up to 60 percent of the solar radiation, resulting in a comparatively small extra loss. The sun’s rays that touch the surface of the earth contain roughly half of visible light, half of infrared light, including traces of ultraviolet as well as other kinds of electromagnetic waves.

Solar energy from the Sun has the ability to generate heat, cause chemical processes, and generate electricity. The overall amount of solar energy incidents on Earth much exceeds the world’s present and projected energy needs. This highly distributed resource has the ability to meet all energy requirements if properly exploited.

Solar energy is predicted towards becoming increasingly appealing as a renewable energy alternative in the twenty-first century due to its unlimited supply as well as non-polluting nature, in comparison to the limited fossil fuel energy, gasoline, as well as natural gas.

With the increased need for clean and green energy, solar energy has become one of the leading alternatives that people are using the world to ward off harmful emissions which are generated from other energy-generating sources.

Pros of solar energy

On a smaller scale, solar energy is employed for reasons other than those mentioned above. Solar energy, for example, is utilized in some nations to evaporate salt from saltwater. Solar-powered desalination systems, on the other hand, turn salt water into potable water by harnessing the Sun’s energy into heat energy, either directly or indirectly, to fuel the desalination process. There are several advantages of solar energy as a source of energy. Therefore, let us see what are the different pros of solar energy

  • Solar energy provides a clean source of energy, whose production does not cause any harm to the environment. Additionally, its usage is also environment friendly and does not release any harmful substances.
  • Solar energy can be used to power vehicles, lamps, turbines, as well as a different forms of machinery.
  • The most common conversion of solar energy is into electrical energy. With the help of solar panels and solar cells, solar energy is directly converted into electrical energy and is used in several spaces.
  • Solar energy is regarded as a non-renewable source of energy and would not replenish over the course of time. Sunlight would always exist as long as humanity exists, therefore, it can be used in abundance.
  • You can store as much solar energy as you want if you have a bigger plant. You can install several solar energy generation plants together, and store the energy coming directly from the sun. Additionally, the solar panel cost is less when compared to other energy generation plants.
  • Additionally, in solar plants, a lot of heat energy is stored and is not reflected back. This reduces the average temperature of the earth’s surface in that area.

Cons of Solar energy

With pros, there are several cons as well with solar energy. Therefore, let us see some of the cons of solar energy as well.

  • The initial expenditure of acquiring a solar panel installation is rather significant. This includes purchasing solar cells, an inverter, batteries, electrical wires, and installation.
  • Nonetheless, because solar technology is always evolving, it is fair to expect that expenses will fall in the future.
  • While solar energy may still be gathered during overcast and cloudy seasons, the effectiveness of the solar system decreases.
  • Solar panels rely on sunshine to successfully collect solar energy. As a result, a few overcast, heavy rainfall can have a significant impact on the electricity system.
  • Individuals should also keep in mind that the energy from the sun cannot be gathered at night. Therefore, there is a very limited time for which solar energy can be collected.
  • The more power you wish to generate, the additional solar panels you’ll need to capture as much sunshine as possible.
  • Solar power system takes up much space to be installed, therefore some roofs aren’t large enough to accommodate the number of solar cells you’d like to have.


Solar technology has indeed evolved as an alternate power source for something like the clean as well as sustainable manufacturing of hydrogen. Artificial plants, which replicate the photosynthesis process, include silicon-based structures which utilize solar energy to divide water into hydrogen as well as oxygen, leaving practically no contaminants behind. More research is needed to increase the productivity and economy of this electric equipment. Therefore, using solar energy can be very beneficial, but everything has its constraints.
