Innovation and economization are two driving principles of renewable power which has high chances of becoming the major source for power in the years to come . It should come as no surprise to learn that solar power researchers may have developed a solution to the technologies historically. Solar Energy is surely the next booming thing that would take over the Energy Industry and dominate over the other energy sources in the next couple of years. The Indian Government has set a target of 100 GW production of solar energy by 2022 to meet the needs of the country.
In layman language, Solar energy is basically the energy that is in sunlight and is extracted from the sunlight. Solar Energy been used for thousands of years in many different ways by people all over the world. Moreover as the days pass by and advancements in technology are being made it is becoming cheaper to make electricity from solar energy and in many situations, it is now replaceable with energy from coal or oil. Moreover, the concept of solar energy has been already started to be used so widely on a small scale as well as a large scale. On a large scale many solar panel farms have been set up to satisfy the energy needs, solar energy has also been seen playing a vital role in households in form of solar water heaters on a smaller scale.
Did you know?
- One year’s worth of solar energy reaching the surface of the Earth would be twice the amount of all non-renewable resources, including fossil fuels and nuclear uranium.
- The solar energy that hits the Earth every second is equivalent to 4 trillion 100-watt light bulbs.
- The solar energy that hits one square mile of land in a year is equal to 4 million barrels of oil.
Basically, the major role behind the Idea of conversion of sunlight into electricity is played by a Solar Cell. Solar Cell basically is a device that is made up of semiconductor materials such as silicon, gallium arsenide, and cadmium telluride, etc. which converts sunlight directly into electricity with the help of concept of conduction. When solar cells absorb sunlight, free electrons and holes are created at positive/negative junctions.
A complete solar electric system consists of a number of components which are required to produce electricity some of which are Solar cells, Solar Panels, Solar Array Mounting Racks, Inverter, Battery Pack, Power Meter, Charge Controller, Circuit Breaker Panel. An Inverter is basically required to convert the DC (Direct Current) produced by the solar panels and batteries into AC(Alternating Current) for use of standard home appliances. As the solar system produces energy during the day when the sun is shining but at night when there is no sun, the Battery pack comes into play and its also important to maintain proper charging voltage for system batteries which is done by the charge controller whereas a power meter is used to measure the amount of power used from the grid. To sum it all up, Solar Energy seems to be the next big thing coming knocking on your doorstep.
