Advantages and disadvantages of solar energy

If you are here, you may be wondering what the advantages of solar energy are, what it is and the existing types of solar energy, because it is all the energy obtained from solar radiation that reaches the Earth in the form of light, heat or ultraviolet rays. 

This type of energy is clean and renewable, since its source, the sun, is nothing less than an unlimited resource. 

To transform solar energy into electrical energy, the electromagnetic radiation coming from the sun is collected by various means (thermal collectors, photovoltaic cells, etc.).

It can be harnessed in two ways: by thermal conversion, which consists of transforming solar energy into thermal energy. Photovoltaic conversion, in which solar panels are used to collect light energy and convert it into electrical energy.

In this way the energy coming from the sun has been used by human beings. And since ancient times in multiple ways, including the oldest and most common which is the simple and direct use of sunlight to dry objects and fabrics. 

All this, through the thermal energy produced by direct rays on a surface.

Importance of solar energy

This energy is important for the planet because it is a renewable energy resource that could reduce our dependence on highly polluting fossil fuels. In addition, it helps sustainable development, reduces pollution and reduces environmental impact.

There are two classifications of solar energy; passive energy and active energy, depending on how it is captured, converted and used.

  • Active solar energy: It is supported by photovoltaic panels and solar thermal collectors, thus absorbing and collecting energy.
  • Passive solar energy: It is simply the one that uses the so-called bioclimatic architecture, it is designed to capture solar energy directly and thus take advantage of it.

Types of solar energy

With technological advances, green energy has been harnessed in different ways and, in turn, has learned to adapt it to the specific needs of human beings, this is divided into: 

Photovoltaic power

It is the one that takes advantage of solar radiation to transform it into electricity. It uses semiconductor panels (photovoltaic solar panels) with silicon cells that transform sunlight and heat into electricity. It is the most developed source of solar energy today and is used in many homes and industries. 

Solar thermal energy


Solar thermal or solar thermal energy uses the sun’s heat to produce hot water for domestic consumption and various purposes (cooking, heating, sanitary use, etc.). The most important are: direct heating of liquids and gases.


Concentrated Solar Thermal Power (CSP)


A type of solar thermal energy that uses mirrors to concentrate sunlight onto a small surface area. Concentrating solar power (CSP) systems produce heat or electricity using hundreds of mirrors. 


These concentrate the sun’s rays at temperatures ranging from 400 to 1,000º C. There is a wide variety of mirror shapes, methods of tracking the sun and generating useful energy, but they all operate on the same principle.




hybrid solar energy


Hybrid solar power is when two energy sources are brought together to produce electricity from a hybrid. A common example is a diesel-photovoltaic hybrid system, combining photovoltaic (PV) power with diesel generators.

What are the advantages and disadvantages of solar energy?

Like any system, solar energy and its devices do not escape from their respective comparative advantages and disadvantages. Obviously some will be more or less depending on the geographical location and place where they are installed or used. 

Here we show you some of the most characteristic details that could be compiled from different sources and even, of own use of some of them.

Advantages of solar energy 🟢 

  • Inexpensive and simple maintenance. Maintaining solar panels is inexpensive and, above all, very simple.
  • Its operation is totally silent. Therefore, you can install them in your house without any problem since they do not generate any kind of nuisance. This is undoubtedly another of the great benefits of using solar energy.
  • Regardless of location or conditions, it allows you to have electricity wherever you live. You will not depend on any electrical grid and why? It’s solar energy!
  • It is a totally profitable bet, your investment is recoverable.
  • Solar panels have a useful life of more than twenty years. Some even reach forty years.
  • Revalue your land or house. When selling a property, it is an added value that it has its own self-consumption system, a great attraction for sales.
  • It is renewable and clean energy, during its transformation process, it does not pollute, contributes to ecological protection and reduces dependence on fossil fuels and batteries.
  • By investing in self-consumption, you will always have the source of solar energy available, sunlight is inexhaustible.
  • One of the best advantages of solar energy is that you do not depend on products or electricity companies, reducing costs enormously in your economy.

Disadvantages of solar energy 🔴

  • Some installation costs are not cheap, depending on the size and the need, although it is recovered, some installations require a good initial investment.
  • It depends on weather conditions; this type of energy requires sunlight, but in places with fog and abundant clouds it will be more complicated to be efficient.
  • It is not constant, since it fluctuates throughout the day and is not available at night. To avoid this disadvantage, energy storage must be used. Its effectiveness is also lower during the winter months.

Gadgets that run on solar energy

For some years now, there has been an imperative need for the use of “handheld” devices or accessories that can be easily transported. Either by its structure, weight or size and comfortable so as not to generate discomfort. 

Faced with a mobilized and technology-dependent lifestyle, a new generation of small-scale sustainable devices is emerging.
