Solar energy is a radiant light and heat that comes from Sun. A light is an electromagnetic radiation that can be detected by human eye.”Energy can neither be created nor be destroyed but it can change from one form to another”. According to this theory, we can say that there are several kinds of energy such as Heat,
Light, Electricity, Sound etc. and sunlight is one of them. Sunlight is the extremely useful source of energy that is received by the earth. When sunlight reaches to the earth’s ground approximate 50% percent visible light, 45% percent infrared radiation and little amount of ultraviolet and other forms of electromagnetic radiation .these radiations can be converted into (heat) thermal energy and electrical energy, photovoltaic cells are used in order to produce electricity , photovoltaic cell is a semiconductor material that displays photovoltaic effects
Solar panel and photovoltaic cell
A Photovoltaic cell is made of semiconductor material like( silicon and metal) .when sunlight touched between two semiconductors .but a single photovoltaic cell produces the power of 2 watts. For producing a large amount of power, we need a solar-panel in which photovoltaic cells are combined together, through which thousands of kilowatts electrical power can be produced in a solar plant. In 1880 Charles Fritts constructed first solar cell later on researcher Gerald Pearson, Calvin Fuller and Daryl Chapin created the silicon solar cell in 1954.
Photovoltaic power stations:
A solar power plant in The Desert Sunlight Solar Farm produces 550 MW power in Riverside County, California, that was first solar thin-film CdTe-modules .since November 2014, the 550-megawatt Topaz Solar Farm was the largest photovoltaic power plant in the world. This was proceeded by the 579 MW Solar Star complex. The current biggest photovoltaic power station in the world is Longyangxia Dam Solar Park, in Gonghe County, Qinghai, China.
USES OF SOLAR ENERGY:
Solar energy captures sunlight to generate concentrated solar power (CSP) photovoltaic power (PV) for solar heating. This energy conversion permits for supplying power, heaters, auto motives and gadgets.
In the entire world, while solar can be used to charge any device or fly the plane. It also can be used as rooftop solar, this can provide a large amount of electricity to use home appliances .but it takes a heavy power storage that contains so many batteries high ampere and large inverter.
A solar charger is a necessary thing for living a modern life.Miscellaneous electronic devices may be charged by a solar charger .such as the tablet, I-pod, laptop computer, E-reader.A solar-powered charger like
Anker’s Powerport can charge so many electronic devices. There are six top listed devices are as follow
- Cell phones
- Music speakers
- Solar air conditioning
- Rechargeable flashlights
By installing outdoor solar lights to your house or property, that is a good way to make home efficiency better as compared to traditional external lights, solar lights don’t require difficult setup as the normal lights require. Rather Solar lights are wireless. these lights are easy to fix.Even the main streets and railway platforms are being enlightened by solar energy.
- Solar street light
- Solar traffic light
- Solar-powered flashlight
- Solar calculator
- Solar cooker
- Solar dryer
- Solar-powered fan
- Solar vehicle
- Solar air conditioning
- Solar cell phone charger
- Solar boat
- Solar Plane
Solar Powered Transportation: Another Use of Solar Energy
An effective or innovative use of solar energy to make transportation better powered by photovoltaic energy. Buses, Railroads, subways, cars and even planes can all be run by solar energy, and solar transit is being a popular thing in the modern energy sector.while, solar buses are helping China to make a healthy better environment for the chinese peoples, where they can take a freely breath without carbonated smoky air.that is another benefit of solar energy power.
Lower cost than others
In the U.S. and Germany, solar already beats the cost of new coal power plants and is supposed to be the same in high markets such as China and India by 2021.
By A recent Survey, New Energy Finance supposes solar energy to be cheapest energy than coal and natural gas with low costs. That after a few years, solar energy will be lower cost than coal almost in the whole world, according to the researcher groups.
The cost of electricity from solar energy or photovoltaic panels has been decreased nearly 25% since 2009 and is expected to end another 66% by 2040.
