Despite the fact that solar energy is not available at nights, the demand for solar energy has swelled at about 20 percent a year over the past 15 years, thanks to increasingly reducing prices and efficiency utilization.
In recent times, the use of solar panel systems has become increased to large extent. Thanks to raising awareness about clean energy, both industrial and domestic users are now switching to solar energy that is reliable, clean and most importantly harmless. One can easily spot large numbers of solar panels installed on rooftops, big fields, and other places. These panels are meant to collect the solar energy and forward it to for further usage. But do you know how these solar panels work. Let’s know about it right here.
Simply put, a solar panel performs by enabling photons, or particles of light, to hit electrons free from atoms, resulting into a flow of electricity. Solar panels essentially are made ofnumerous, smaller units called photovoltaic cells. These cells are linked together to constitute a solar panel.
Each photovoltaic or solar cell is typically like a sandwich which is made up of two slices of semi-conducting object, generally silicon — the same material used in microelectronics.
In order to function, these cells need to set up an electric field, very much similar to a magnetic field. Due to contrasting poles, an electric field emerges out during the separation of opposite poles. To save this field, scientists cover silicon with other materials, enabling each slice of the sandwich a plus or minus electrical charge.
Several other components of the solar cell turn these electrons into practical power. For example, metal friendly plates fixed on the sides of the cell gather the electrons and transport them to wires. At thisstage, the electrons tend to flow like any other form of electricity.
There can be other kinds of solar power technology — such as solar thermal and concentrated solar power (CSP) — that function in a different way as compared to than photovoltaic Solar System panels, but all yield the power of sunlight to either produce electricity or to heat water.
Over the past few years, the cost of getting solar power has become tremendously easy and cheaper. Thanks to modern technologies that have opened new avenues for people to embrace this new renewable source of energy. Due to this, there has been a dramatic rise is the sale of solar panels and advanced solar system. Solar panels tend to be rated on efficiency and the power output under standard laboratory conditions. In this post, you will get to know about solar panel and its functioning.
Extreme temperatures tend to lessen the voltage of a Solar Cell — which, you may easily understand that a bad thing. Orthodox rooftop solar systems can lose as much as 30 percent of their electricity outcome on hot days in summer.
Another factors that make panels lose power is that they get dirty. The effects of “soiling” differ extensively by location, but energy harvest sufferers of 10 percent are rare. Research on environmental conditions and panel maintenance procedures could help people deeply understand how and why panels lose power to dirt, which in turn could lead to better prediction of soiling from one solar energy system to another and more effective dirt-resistant treatments for PV module glass.
While heat and dirt diminish solar panels’ energy crop in an easy direct way, shadows are a bit more complex. In situations when a pale cloud goes over the solar module, the power stages just get reduced. However, many times the light is totally or habitually blocked by an enduring structure – such as a utility pole that cover just one side of the module — which can really lead to “hot spots” that tend to damage the module over a period of time.
In today’s times when pollution has augmenting like nothing else, the life of our planet is at greater risk and needs prompt attention of ours. Though we humans are bringing in more advanced technologies and launching plantation drives, the possibilities of planet revival are pretty less and we need to change our approach towards energy generation and its consumption. At present, it can be easily said that solar energy presents a bright future in this regard.
The whole objective behind using solar energy is to harness the power of sun to make life easy. As per the data of 2011, the advancements produced less than one tenth of just one per cent of global energy requirements. When it comes to Solar Energy Manufacturing, the role of photovoltaic cells is paramount that are typically found on objects such as spacecraft, rooftops and handheld calculators. These cells are made of semiconductor materials such as those found in computer chips. When sunlight is places on the cells, it makes electrons release from their atoms. As the electrons flow through the cell, they result into electricity generation.
In case of large scale Solar System, solar-thermal power plants make the use of various techniques to focus the sun’s energy as a heat source. The heat is then employed to heat up water to initiate a steam turbine that produces electricity in much the same way as coal and nuclear power plants, delivering electricity for millions of people.
On a primary note, long channels of U-shaped mirrors with direction on sunlight are fixed to a pipe of oil that runs through the middle. The hot oil then boils water for electricity generation. Another wayemploys moveable mirrors to focus the sun’s rays on a collector tower, where a receiver rests. Molten salt flowing through the receiver is heated to move a generator.
Other solar methodologies are found to be submissive. For instance, large windows fixed on the sunny side of a building enable sunlight to heat-absorbent materials on the floor and walls. These surfaces then loose the heat at night to make the building warm. In the same way, absorbent plates placed on a roof can warm liquid in tubes that supply a house with hot water.
Solar energy is largely considered as an unlimited fuel source that is pollution- and habitually noise-free. So, if you want to do your bit to protect nature, switch to solar system today.
