Solar energy is that delivered by sun powered radiation and is the principle wellspring of vitality for our planet. Directly or indirectly, this energy is derived from others such as wind, hydroelectric and wave movement. Currently, it is the most used energy source after hydraulics.
This is due in the first place to the fact of being a renewable and clean energy. Secondly, because it is a free energy, since the king star is present in all places on Earth.
The use of solar energy is so versatile that it is being used to solve problems of daily domestic life in many localities (even remote ones), as well as in other industrial, urban and satellite environments.
Advantages of Solar Energy
Solar energy offers innumerable advantages in the life of man on Earth. Its maximum use depends on the human being and his growing energy needs.
Here are the five most important Advantages of Solar Energy:
He is Inexhaustible
When talking about solar energy we can attest that it is an inexhaustible and renewable source since it comes from the sun, which eliminates the worry that it may end.
This makes it always available, and even when its intensity has variations in different parts of the planet, it can always be used from remote places.
It is not Polluting
One of the most important advantages of solar energy is that it is much cleaner than others, since its use does not produce polluting gases. This, in addition to contributing to the environment because it protects ecosystems, helps in the fight against climate change and the greenhouse effect.
The use of solar systems produces energy with very low environmental impact; this is because it does not need fossil raw materials to carry out its combustion processes, preserving the atmosphere free of harmful substances.
Solar energy is a considerable reduction of money in many ways, comparatively speaking in relation to the costs involved in the use of fossil fuels.
As technologies advance in the storage, distribution and transformation of solar energy, money saving is increasing.
The reduction of electricity bills is making this energy one of the most sustainable now and in the future, since the costs of its production are increasingly lower than the maintenance of solar panels, pipes and other structures.
Solar energy can be used in many ways and in an unlimited way, through structures or systems that produce and transform that energy into others that facilitate daily life.
They can even promote large industrial projects, such as in the automotive and satellite sectors, to name a few. An example of this is the solar thermal system, which allows the use of the sun’s heat to heat fluids that are used to heat houses.
Disadvantages of Solar Energy
There are procedures that must be further refined in order to achieve more efficiency and effectiveness in the application and in the necessary resources. There is also a need for more experimentation in order to counteract the negative effects that can be generated in man and in the environment.
Some of the most relevant disadvantages of solar energy are the following:
High installation costs
Initially the solar panel installation of the systems requires a high investment of money, especially if the panels are added batteries, which are usually recommended in home installations.
The lower the density of the solar power, the greater the amount of space required, which necessarily increases the initial investment costs. It is advisable to request government financial support for each project.
Currently solar plants are installed in deserts or semi-desert climates, which are fragile ecosystems that are altered by the intervention of man and the material elements found there.
The same happens with concentration systems, which use significant amounts of water and affect the wells or aquifers of the installed areas.
On the other hand, the uses of chemical products that are poured into the soil to eliminate plant growth in the areas where plants are installed alter the natural balance of the environment in general. The toxic waste materials that remain from the manufacture of the panels are also harmful.
Solar energy depends on the sun and several factors for that energy to be constant. These include climate, incidence according to latitude and environmental conditions.
If the weather is cloudy, the intensity of the solar rays will be lower and in that same proportion will be its energy. Something similar will happen with respect to latitude: it will produce a variation of the solar rays on the surface.
Also, the thickness of the atmospheric layers of the Earth – which is different at the equator in relation to what happens at the poles – influences both the incidence and the intensity of the sun’s rays, affecting the use and use available of that energy throughout the year in the localities of the planet.
Large tracts of Land needed
Another major disadvantage of solar energy is the need to use large areas of land for the installation of systems.
This may result in the occupation of land suitable for other activities, which is why it has been chosen to locate the power plants in desert areas, some of which are distant from inhabited areas but with a high density of sunlight.
Little clarity about the recycling of panels Finally, it is important to highlight the study currently carried out by companies on the recycling or reuse of the materials used to make the solar panels once their useful life has ended. It is estimated that within 20 years these systems will have to be discarded and could have an impact on the environment.
