Principles and Specificities of the Solar Panels Functioning
Sunlight had been around far longer than the planets of our Solar System. It has ensured the birth and the evolution of life that we know now. Without the Sun, the Earth would have been just a frozen piece of stone, floating in space. Even the water, the source of life, wouldn’t be able to give birth to the first bacteria without the sun’s warmth.
Humanity succeeded to transform the sun’s energy into electricity.
The possibility to transform direct sunlight into energy was discovered a long time ago, in the distant 1842 by a French inventor, Alexandre-Edmond Becquerel but only in 1948, a group of Spanish scientists succeeded to create the first prototype of the existing solar panels.
Solar panels rapidly became demanded and only in a few years, the first satellites, equipped with solar panels entered the Earth’s atmosphere. But they have found wide application on the Earth’s surface.
Now solar panels are commonly used for green energy production
Since fossil resource reserves are depleting rapidly and considering the growth of humanity’s demand for electricity, green energy became an integral part of the world’s economy. And solar panels provide us with a bigger part of it.
Solar panels structure is relatively simple, much simpler than the structure of the atomic reactor, and it includes only a few main elements – a light-absorbing layer, predominantly made of silicon, and a conductor that transforms and conducts energy to the batteries.
A solar battery consists of an uncountable number of tiny solar cells that constitute the silicon layer. Those cells are conducted within a frame and are connected to a conducting layer. When solar cells heat up, the electrons begin to release. After this, a conducting layer transforms them into the electricity that, in turn, is conducted to a battery.
Batteries store all the gained electricity, providing the electric system with power. Basically, solar panels produce electricity while being heated by the sun so the warmer and brighter the sunlight light, the more electricity one solar battery will be able to produce.
It’s impossible to tell how much electricity a solar panel produces because it completely depends on the specifics of a certain panel, its area, reflecting material, and the weather. On average, in a mild climate during a bright sunny day, a regular solar panel can produce two and a half kWh a day. It is a tenth part of the electricity intake of a regular household in the US.
Solar power generates pure and green electricity
Solar power generates pure and green electricity which is important because fossil-fueled and atomic power plants release big numbers of CO2, greenhouse gases, and radioactive waste. Solar panels work continuously, they are very easy to maintain and service, and solar panels functioning doesn’t require any additional costs or resources.
This is green energy and someday, when fossil resources will end, the solar, wind, and hydro energy will become the main source of electricity without which further technological and social progress would be impossible.
