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.
