Advantages and Disadvantages of Solar Energy {Pros & Cons}

Advantages and disadvantages of solar energy

Solar energy test

We have been using non-renewable energy sources for a long time, which means that their availability is decreasing day by day and their cost is also increasing. Moreover, greenhouse gas emissions from the combustion of non-renewable energy sources are polluting and thus increase the negative effects of global warming.

Now we need to switch from non-renewable to renewable energy within an hour to solve the problems and meet the needs. Solar energy is the light and heat emitted by the sun. Solar energy is the most readily available energy source. It is rich in nature. It is also the most important unconventional energy source because it does not pollute the environment, thus contributing to the reduction of the greenhouse effect and becoming one of the alternatives to fossil fuels.

Pros and cons of solar energy

As a non-traditional energy source, solar energy has both advantages and disadvantages, or advantages and requirements. We will first look at the advantages of solar energy, then the disadvantages.

Benefits of solar energy

Not harmful to the environment:

Because solar energy uses both radiation and sunlight, it is clean and reliable. Thus, it does not produce harmful gases such as carbon dioxide, nitrogen oxide, sulfur dioxide, etc.

May be used in a variety of ways

Solar energy can also be used in the form of solar thermal, solar photovoltaic, solar thermal, etc. according to your needs.

Suitable for remote locations:

Solar power can be easily installed in an isolated place where there are no power lines because it uses direct solar energy.


Solar energy is inherently sustainable because it has no moving parts and makes no noise, so it requires much less maintenance.

Saving ecosystems

Because solar energy does not rely on the permanent extraction of raw materials, it does not cause the destruction of forests and ecosystems that many fossil fuels do.

Disadvantages of solar energy

Purchasing costs

The initial cost of manufacturing and purchasing solar panels is high, which is a major problem. The cost of installing the solar panels is a bit high.

Location and availability of sunlight

Location and accessibility are important for electricity generation. In an area where it is usually foggy or cloudy, the production rate is slow and more signs may be needed. Solar collectors cannot produce more energy in the winter. The production of solar energy requires a large installation area.

Storage and weight

The potential of solar energy storage technology has not yet been exhausted, but the weight of solar modules is also cumbersome.


A solar power plant does not achieve the same output power as a conventional plant and the construction costs are not the same.


Since not all sunlight is absorbed by solar cells, most solar cells have an efficiency of 40%, which means that 60% of the sunlight is wasted and not used. However, new emerging technologies have increased the efficiency of solar panels from 40 to 80%, but on the other hand, they have also increased the cost of solar panels.


As an unconventional energy source, solar energy has advantages and disadvantages.
