Be it central heating, generating electricity, water heating, producing salt, cooking or doing desalination, solar energy can be and is the go-to option. Rays of the sun generate energy, and hence it is termed as solar energy. Solar energy is considered eco-friendly. Sun rays while entering the atmosphere of the earth, are a bit dilute.
Even though solar energy is considered as eco-friendly, it has both pros and cons. Let’s discuss both aspects of solar energy.
Why is solar energy considered advantageous?
Solar energy is free from all dust and dirt. Nothing more than sun rays is required for heat or electricity production using solar energy. Not even the combination of fossil fuels and sun rays for heat or electricity production. For collecting solar energy, all one requires is either solar power panels or a collector for solar energy.
Between solar energy and electric heating, the former is more affordable, which gives solar energy an edge over others. Expenditure done on heaters can be saved by replacing them with solar energy.
By replacing heaters with solar energy, expenditure occurred on the heaters, in paying electricity bills and in its maintenance, can be saved.
Solar energy is also the solution for people living in outlying areas with no access to power-lines. Even the power companies are unable to find ways to access these areas. All the requirements of a good alternative for electricity, hot water as well as cooking, are fulfilled by solar energy.
Apart from all this, solar energy is beneficial for the purpose of desalination in the areas that are deprived of fresh drinkable water. Solar energy is helpful at it makes the brine evaporate, leaving all salt crystal settled at the bottom of the washing-basin. Then that water undergoes condensation is a different basin where it is free from all the impurities and absolutely drinkable.
Disadvantages of solar energy system
Stated above were the pros of solar energy and now let’s discuss the cons, to get a complete picture.
Being dilute is one of the biggest drawbacks of solar energy. Also what is low priced is just the solar energy in itself and not its collectors that require a good amount to be purchased and maintained at a regular basis in order to be able to work in a proper and efficient manner. Before pursuing solar energy, one should do some calculations of return on investment and ensure that it is higher than the investment done in the first place.
Access to sun rays is a must for solar energy and is also one of the major disadvantages. Amongst all the people on this lovely earth, only those who live in areas where sunlight is in abundance, can make the use of solar energy. Solar energy collectors do not prove to be much efficient in areas where the clouds hinder the sun rays. One must be assured that his/ her area receives enough sunlight during most of the year. Undoubtedly, Arizona, Mexico, and other desert areas have an abundance of sunlight for almost the entire year making solar energy collection favourable, so if ones reside somewhere there, he can easily use solar energy.
Ultimately, there is no sun at night. Making electricity or heating water is easily possible only during the day when the sun is out. An ‘old’ utility grid as a backup or any other source of storing electricity so that it can be used later, is required as an alternative. Also, battery systems are available that have the capability of storing energy for our later uses.
So the pros of solar energy mainly are that is absolutely clean and can serve as an unconventional heating system, the cons of it should also be taken into consideration. So before making any decision on whether to use solar energy or not, one must go through this article.
