In very simpler words, “Solar Power or Solar Energy” is an energy that is derived from the sun.
We all know that the “Sun” is an abundant source of energy and it gives plenty of heat & light. Not only this, the ancient Egyptians even worshiped the Sun. They considered it “God”. And truly, it is not misguided respect.
The Sun certainly has an unlimited source of power and the benefits of using “Solar Energy” are numerous.
Zero Recurring Charges
With every sunrise, with each dawn, Sun releases the solar energy. It is pure and filtered through the layers of the atmosphere, which not only provides light but also radiates heat. This has been happening since the beginning of life. However, we have begun to capitalize on this infinite power recently.
In the past decades, Greeks and Egyptians have been really popular to utilize the power of the sun to heat and cook whatever they wished to.
Solar energy is that form of energy which is free of any pollutants. Fuels like petroleum and even organic ones leave back the residues and harmful gases when utilized to create energy.
The sun has been happily and peppily burning for roughly four and a half billion years now. Our fresh and calm mornings start with the sun-rise and evenings end up with the sun-set. With every sun-set on our side, the sun brightens and lightens up the other side of the globe. With this, every part of globe can store its energy and utilize it in one way or the other.
There are no Pre-paid or postpaid plans because there is no limitation on how much solar energy we can use. In fact, if we can efficiently and effectively utilize this immense energy, we can simply power up an entire country, which can also solve the world’s energy issues.
Ever thought of why Solar Energy is a boom nowadays? Why did no one talk about this in earlier times? If there is so much of energy, why did we not efficiently harness it?
One of the major reasons, why this powerful source energy went underutilized is the fact that the sunlight we receive is very thinly scattered across the globe, due to which we can’t harness it easily.
The only practically possible way to harness the power of the sun is that we would need a method(s) that can focus, manipulate and store the sun’s energy. It is easier said than done, however, we humans have managed a few ways to collect solar energy.
The Reflection Method – Mirrors / Parabola
This method is based on concentrating the rays of the sun through a single/multiple mirrors on one point and then utilizing the heat produced. A parabolic mirror also works the same way.
The Radiation Method
This is what is used behind the solar water heaters. Black painted pipes between two layers of glasses containing water gets heated due to the sun rays.
This is the most recent invention, the “solar cell”. These solar cells are composed of silicon crystals, which when hit by sun rays, knock out electrons out of their orbits. This, then create a void that needs to occupy by electrons from other silicon crystals. This further creates an imbalance of electrons, due to which a flow of current is produced to be immediately utilized. This current can be stored in a rechargeable battery.
Due to various technological limitations, we are still not able to commercially generate enough power without occupying huge surface areas. One cannot completely rely on solar energy as, during cloudy days/monsoons, it will be next to impossible to harness solar power.
However, constant innovation, research, and development of Solar Energy now results in many efficient solar cells. In this, a fraction of the size of existing cells can churn out much power.
