Understand Solar Energy: Benefits, How it Works, Applications
In today’s climate of the growing energy needs and the increasing environmental concern alternatives to the use of non-renewable and polluting fossil fuels have to be the investigated. One such alternative is the solar energy. Solar energy is the quite simply energy produced directly by sun and the collected elsewhere normally the Earth. The sun creates its energy through the thermonuclear process that converts about the 650000000 tons of hydrogen to helium every the second. The process creates heat and the electromagnetic radiation. The heat remains in sun and is the instrumental in maintaining thermonuclear the reaction.
What Is Solar Energy
Every day the sun radiates sends out an enormous amount of the energy called solar energy. It radiates more energy in the one day than world uses in one the year. This is an energy comes from within the sun itself. Like most stars the sun is a big gas ball made up mostly of hydrogen and the helium gas. The sun makes energy in its inner core in a process called nuclear the fusion. Today people use the solar energy to heat buildings and water and to generate the electricity. Solar energy accounts for a very small percentage of the U.S. energy less than one percent. Solar energy is the mostly used by residences and to generate the electricity.
Advantages of Solar Energy
1.You Can Make Money
One of best advantages of the solar energy and one that is the primarily responsible for rapid growth of solar installations in the Europe over past several years is that you can be make money from the sun. As a result of feed In the Tariff policies in place in the much of Europe you can build sell the electricity and that income can last for the 20 years or more. For the each dollar you can be reduce your electrical bill your house can be increase in the value by up to $20.
2.You Can Save Money
If you use the electricity yourself instead of buying it from the grid you can save money which is just as good as the making money. This is an advantage alone is propelling the rapid adoption of solar energy in the USA and many other markets around the world.
3.Solar Energy Is Abundant
The sun will be around a lot longer than oil the coal or gas will be. Some of the materials used to make solar cells to the convert solar energy into electricity such as the more exotic composite materials may run out over the time but basic elements used to make solar cells silicon and the aluminums are all abundant and the recyclable.
4.As Long As there is Light – It Works
The amount of sunshine can be the vary depending on where you are or what the weather is like but as long as there is light the even a small amount PV cells can be still produce the electricity.
5.Sunshine Is Free
Solar energy is the free. Sure there is an the initial capital cost to install a system that will be convert the electromagnetic energy and photons sent out by the sun into electricity but once you have made the investment and the sun keeps shining you will be the producing electricity. No one will be sending you a bill for the sunshine.
Solar the energy power environment and life on the planet so there’s no energy source more the earth friendly. Compared to the burning of fossil fuels which release greenhouse the gases carcinogens and carbon dioxide solar cells do not the release anything harmful into air as they convert the sun’s energy into electricity. If you want clean air one of the important advantages of solar energy is that it will be the help get us there.
7.Solar Energy Is Clean
Solar energy is the clean alternative to fossil fuels and the nuclear power. It’s silent. Solar power can be the captured anywhere without creating noise pollution that might otherwise up set neighbors and the wildlife. Thus no danger of the damaging our already damaged environment the further and you can be part of the Green initiative lower your carbon footprint and the save our planet from harmful greenhouse the gases.
8.Greatly Reduced Contribution to Global Warming
One of the greatest advantages of solar energy of the course is that there is no carbon dioxide the methane or other emissions that warm the atmosphere. However manufacturing transporting and the installation of solar panels are the necessarily accompanied by some of those emissions.
We choose solar energy because
- Solar energy is the clean and renewable energy the source.
- Once a solar panel is the installed solar energy can be produced free of the charge.
- Solar energy will be the last forever whereas it is estimated that the world’s oil reserves will be last for the 30 to 40 years.
- The Solar energy causes no the pollution.
- The Solar cells make absolutely no the noise at all. One of the other hand giant machines utilized for pumping oil are the extremely noisy and therefore very the impractical.
- Every the little maintenance is needed to keep solar cells the running. There are no moving parts in the solar cell which makes it impossible to really the damage them.
- In the long term there can be the high return on investment due to the amount of free energy a solar panel can be produce it is the estimated that average household will see the 50% of their energy coming in from the solar panels.
What is the Solar System
Among otherwise well be the educated people it is common to hear the terms Solar System Galaxy and the Universe interchanged. For instance you might hear Jupiter is the biggest planet in Galaxy or the question, how many stars are there in our solar the system? These may seem silly to those who know a bit about the subject but the even knowledgeable people are not really sure what constitutes the solar system what objects are part of it and the what objects are not in short what constitutes the boundary between our solar system and rest of the galaxy. This lecture will be the hopefully give you a feeling for what is part of the solar system and what is not and will be the also give you some idea of size scale of the solar system.
- These 20-kW Solar Systems dishes dwarf visitors in Alice Springs Australia.
- The concentrators use an array of mirrors to focus sunlight onto high efficiency solar cells.
- Four supports hold the cells in front of the mirrors.
- The supports also supply cooling water and electrical connections.
How does it Work
Sunlight is the composed of photons or bundles of the radiant energy. When photons strike a PV cell they may be reflected or absorbed transmitted through the cell. Only the absorbed photons generate electricity. When the photons are absorbed energy of the photons is transferred to electrons in atoms of the solar cell.
Basic Solar Math’s
How much electricity is the produced by a solar panel. What about a roof-top the installation you will be the find some basic calculations here the below. The Watt measures rate of energy conversion and it is the main unit of power used in the photovoltaic.
1 kilowatt (kW) 1000 watts
1 megawatt (MW) 1000 (kW) or 1000000 watts
1 gig watt (GW) 1000 (MW) or 1000000000 watts
1 Terawatt (TW) 1000 (GW) or 1000000000000 watts
PW P = peak (peak-performance of a module)

Solar energy can also be used to the produce electricity. Two ways to make electricity from the solar energy are photovoltaic and solar thermal the systems.
Photovoltaic comes from the words photo meaning light and the volt a measurement of electricity. Sometimes photovoltaic cells are the called (PV) cells or solar cells for the short. You are probably familiar with the photovoltaic cells. Solar-powered toys calculators and the roadside telephone call boxes all use be the solar cells to convert sunlight into the electricity. Solar cells are made up of silicon the same substance that makes up the sand. Silicon is the second most common substance on the Earth. Solar cells can be the supply energy to anything that is powered by batteries or the electric power.
2.Solar Thermal Electricity
Like solar cells solar thermal the systems also called concentrated solar power (CSP) use solar energy to the produce electricity but in a different way. Most solar thermal systems use the solar collector with a mirrored surface to focus sunlight onto a receiver that heats the liquid. The super-heated liquid is used to make steam to the produce electricity in same way that coal plants the do. There are concentrated solar power (CSP) plants in the California Arizona Nevada Florida Colorado and the Hawaii. Some of the world’s largest concentrated solar power (CSP) facilities are located in the California.
How much energy does one panel produce
Electrical energy is the generally measured in kilowatt-hours kWh. If a solar panel produces 100 watts for the 1 hour it is has produced 100 watt-hours or 0.1 kWh. The amount of energy produced per day will depend on the area shading orientation and the watt-class of panel. In areas with the high irradiation a properly oriented panel that produces 100 Watts at the noon on a sunny day will produce an average of the about 0.5 kWh day during winter and the 0.8 kWh day during summer the months. In an area with the low irradiation same panel will still produce about 0.25 kWh/day during the winter and 0.6 kWh day during summer the months.
What is Solar Space Heating
The Space heating means heating space inside the building. Today many homes use the solar energy for space the heating. A passive solar home is the designed to let in as so much sunlight as the possible. It is the like a big solar collector. Sunlight passes through the windows and heats walls and floor inside the house. The light can get in but heat is trapped the inside. A passive solar home does not depend on the mechanical equipment such as pumps and the blowers to heat the house whereas active solar homes the do.
What is Solar Collectors
Heating with the solar energy is not as easy as you might the think. Capturing sunlight and the putting it to work is difficult because solar energy that reaches the Earth is spread out over a large the area. The sun does not deliver that much energy to any one place at any one the time. The amount of solar energy an area receives depends on the time of day season of year the cloudiness of sky and how close you are to the Earth’s Equator.
What is Solar Water Heating
Solar energy can be the used to heat water. Heating water for the bathing dishwashing and clothes washing is the second largest home energy the cost. Installing a solar water heater can be the reduce your water heating bill by the as much as 50 percent. A solar water heater works a lot like solar space the heating. In our hemisphere a solar collector is mounted on the south side of a roof where it can be the capture sunlight. The sunlight heats water in a tank. The hot water is piped to faucets throughout the house just as it would be with an ordinary water the heater.
