This article contains a lot of information on solar energy. You can use this essay as solar energy essay for your exams. This essay can help students with their studies on solar energy.
What is solar energy?
Simply the definition of solar energy is “The energy you get from the sun is solar energy.” In broad sense solar energy is that type of power which produces from sunlight through some combination of tools, all together they may call solar-system. In short, it is the conversion energy of sun rays into electricity.
Sources of solar energy.
Undouble the source of solar energy is the Sun. In fact, all the source of the power that exists in the earth is the sun. Energy never vanishes, it just converts from one source to another. The heat from the sun also does the same task.
Who invented solar energy?
There is some opinion about the invention of solar energy. Some say the origin of the solar energy is some very ancient bacteria. Alexandre Edmond Becquerel who discovered the photovoltaic effect. Photovoltaic effect explains how electricity generates from sunlight. For this magnificent observation, Alexandre Edmond Becquerel called the inventor of the solar panel.
Now, what is the photovoltaic effect?
Well, it is the theory of the whole system, in which solar energy converted to electrical power. According to Einstein, Sunrays come to earth as the photon. A negatively charged material reflect the proton of this photon through a specific direction. We can collect this one-way proton. We will learn the process of the photovoltaic effect more in next.
Solar energy panel
A solar panel is the assembled system for the process of generating electricity from the sun. It is a combination of diode, semiconductor, and resistor. There is also a battery connected to the solar panel to store the power.
Solar energy system
To understand solar energy system, we first need to know how a solar panel that means how solar energy works? Let’s elaborate it.
How does solar energy work?
Well, it is the most common question to all, who wants to know about solar energy. Solar energy! How does it work? The great scientist Sir Albert Einstein is the pioneer of every cosmic stuff. At first, he analyzed the sun rays and opened that, the sun rays come as the packet of a molecule called the photon.
Primarily photon is positively charged. A plate, prepare with semiconductor like silicon are doped with p-type materials. That means this is also full of protons. There is also an n-type material along the plate. Together they called p-n junction. The length between this two-part is very thin.
The p-type doped materials have holes. The hole is lack of electrons. Again the n-type material has few free electrons which want to go to the p-type material.
Solar energy conversion system
After setting up the above things, the plate set to the sun. The n-type part faces the sun. When sun ray falls on the plate that means the photon hits the n-type electron.
By this hitting n-bond break and make free electron into the n-type area. At the same time, the proton starts to travel to fill the hole in the p-type region. The direction of this travel is a certain way.
An external positive power applies to the n-type material to collect that free electron. This electron can store or can use any external power stuff. It is a continuous process. The external power is too low. It is just to make a charge between the junction to make this process automatic.This is the fundamental concept of solar energy generating systems.
Solar Energy Advantages and Disadvantages
It is an inherent character of all the stuff in the world. In fact, there is no system without some advantages and disadvantages. Although to save fuel for our future energy, Solar energy is the best alternative, but it has some limitation too.
Advantages of Solar Energy
- For the benefit of the world, solar energy can play a vital role. Solar energy advantages are more useful than other energy sources.
- The non-renewable is getting low. In this case, solar energy can be the best replacement for that coal, fossil, and nuclear energy.
- As solar power can get from nature, there is no way of pollution. Example: Carbon-dioxide and harmful gases.
Pollutions will stop permanently like air pollution, sound pollution and all which happen during other power extraction.
- As the Sun is the raw material of this solar power plant, there is a never-ending source of power.
Solar energy can easily use for electricity, lighting, heating, cooking even in massive operations like satellite and huge power project.
- It can adjust in anywhere, where sunrays can go. The exciting thing is, you can run some of your home appliances with a simple setup on your rooftop. This is obviously without any cost except installation.
As this is an uninterrupted source of energy, you can delete the word Power cut.
Solar Energy Disadvantages
As there is some limitation of solar energy, there are some disadvantages of solar energy too. These are
- The first point is efficiency issue. The solar panels are not efficiently modified to give 100% feedback. This may upgrade with the upgradation of solar panel technology. Till Now we can only use the 10% of the energy that comes from the sun in a solar panel
- We do not get the sunlight all the time in 24 hours. On the other hand, dust, shade and other substance make an obstacle to getting power all the day long.
- We need storage devises to store the solar power. But adding additional storage system is quite costly.
- We cannot rely on solar energy in cloudy weather and rainy seasons. Also not possible in extremely cold weather.
- Solar kits are quite large to meets your daily need. They are also fragile too.
- The ultimate density of solar power is less than the fossil and nuclear power.
- Too much costly to produce solar power commercially.
Solar energy systems for homes
In today’s, most often we see the uses of solar energy system for homes in every house. Although, we use it for general purpose. It just needs a simple installation of pre-made solar systems equipment. In general, you need 12 to 17 panels to get 980 kWh per month. Based on your need you can increase or decrease the panel to get your estimate power supply.
Based on how much solar energy lamp, solar energy lights, solar energy charger you need to install the perfect solar energy battery. The capacitance of the cell should consider when buying. Because if the battery performance does not look good, you may face problems while using your stuff.
Solar energy projects
Regarding the benefits of solar energy, many countries are planning to run solar energy project commercially. Most of the first world country already started production from their solar energy project. Even the space station is also dependent on this solar system. The top five biggest solar energy project in the world is
|Tengger Desert Solar Park||China||1547|
|Datong Solar Power Top Runner Base||China||1000|
|Kurnool Ultra Mega Solar Park||India||1000|
|Longyangxia Dam Solar Park||china||850|
|Kamuthi Solar Power Project||India||648|
Solar energy companies
Some solar energy companies are trying to spear this renewable energy to the people of urban areas. There are some top companies
Top Solar energy companies in the United States is “Solar star 1 and 2.”
Top Solar energy companies in India is “Tata Power Solar Systems Ltd.”
Top Solar energy companies in Bangladesh is “Grameen Shakti.”
Top other companies were also in the previous section.
Solar Energy Stocks
The ratio of investing in the solar system is getting higher that is why solar energy stocks are also getting higher. It is so reliable that its share never gets down. The top three solar energy stocks are First Solar, SunPower, and SolarEdge.
Solar Energy Jobs
Depending upon the increasing need of solar power this market is growing high. To emits this need, many organizations are developing solar systems. Their primary target is the people of the urban area. As there is a lot of peoples live in urban areas, they need electricity. Solar energy companies need human resources to fulfill this demand. As a result, job vacancy is also creating. Above all solar energy, jobs may be a smart career.
Solar Energy Kit
You need some tools for a solar energy project in the home. The solar energy kit includes
Solar panel, Home UPS 1100, Solar power conditioning unit, Inverters, Solar charging controller, PWM Technology, MPPT Technology, Solar Conversion Kit, Solar Shine Wave Inverter, Solar battery, Solar Home Lighting System, Sparkle, Solar glasses, Solar Street Lighting Systems, etc.
At last, we can agree that solar energy will be our future friend. This eco-friendly power is the best alternative to fossil energy. We all should try this natural power for the better fare of the solar energy world.
