BACKGROUND OF SOLAR PANELS
WILLIAM GRYLLS ADAMS
IMPACT ON SOCIETY
QUICK FACTS
- Space missions by various countries use solar energy to power their spaceships.
- Though the sun is 90 million miles from the earth, it takes less than 2 minutes for solar energy to travel from that much of distance.
- If you have solar panels your home is immune to black outs/power outages and will continue running like normal
- Solar panels can produce 1-kilowatt (KW) of solar energy to replace the equivalent of burning 170 pounds of coal and 300 pounds of carbon dioxide.
THE IMPACT OF SOLAR PANELS ON SOCIETY
Solar Panels are a source of energy designed to absorb the sun’s rays for distributing heating and electricity in a more eco-friendly way.
Solar Panels were invented in 1876 by William Grylls Adams along with a student of his, Richard Day, when they discovered that once selenium was exposed to a light source, it created electricity. However it took the pair many years to perfect their ingenious invention. And it was only until after the pair died that it was available for retail use
Adams and Day created Solar Panels as a way to cut down on wasting electricity in households and distribute energy in a eco-friendly manner that would preserve many of Earth's natural resources and would not harm the environment.
Thanks to William Adams and Richard Days’ brilliant solution to cutting down on wasting energy, Solar Panels have revolutionized how electricity is distributed in households. Not only that but it is eco-friendly, does not expose harmful gases, is low maintenance and produces sustainable and renewable energy. Now more than 10 million homes use solar panels from the 30,000 homes that used it in 2006 when it was first put on the market for retail purchase.
William Grylls Adams was the creator of Solar Energy. He was born on 18 February 1836 in Laneast, Cornwall and died on April 10 1915 in London. He was a graduated from St Johns Cambridge in 1855. In 1876, Adams and Richard Evans Day discovered that illuminating a junction between selenium and platinum has a photovoltaic effect. This first demonstrated that electricity could be produced from light without moving parts and led to the modern solar cell.
From 1878 to 1880 he was President of the Physical Society of London. In June 1872 he was elected a Fellow of the Royal Society and in 1875 delivered their Bakerian Lecture He was president of the Institute of Electrical Engineers and of the mathematical and physical section of the British Association
How does Solar Energy Work?
Simply put, a solar panel works by allowing photons, or particles of light, to knock electrons free from atoms, generating a flow of electricity. Solar panels actually comprise many, smaller units called photovoltaic cells. (Photovoltaic simply means they convert sunlight into electricity.) Many cells linked together make up a solar panel. To work, photovoltaic cells need to establish an electric field. Much like a magnetic field, an electric field occurs when opposite charges are separated. To get this field, manufacturers mix silicon with other materials, giving each photovoltaic cell a positive or negative electrical charge. They put phosphorous (a chemical element) into the top layer of silicon, which adds extra electrons - with a negative charge, to that layer. Meanwhile, the bottom layer gets a dose of boron (a metalloid chemical element) , which results in fewer electrons, or a positive charge. This all adds up to an electric field at the junction between the silicon layers. Then, when a photon of sunlight knocks an electron free, the electric field will push that electron out of the silicon junction. A couple of other components of the cell turn these electrons into usable power. Metal conductive plates on the sides of the cell collect the electrons and transfer them to wires. At that point, the electrons can flow like any other source of electricity.
Solar Panels have already had a large impact on society and if their use continues to grow they will have an even larger impact. Solar Panels are the first energy source that produces sustainable and renewable energy, which is vital for the future of the next generations on Earth. The reason Solar panels are so important for the earths future is they produce significantly less air pollution than traditional sources of electricity(fossil fuel sources) like coal. Solar panels are emission-free therefore making the air cleaner and safer for communities and cities where there are The use of solar panels to generate energy provides many benefits, which include reductions in the costs associated with generating electricity. Because of saving money on electrical bills, your family would be able to go more vacations, have access to more luxuries and many more benefits as a result of installing solar panels. Compared with fossil fuel technologies, which are typically mechanized and capital intensive, the renewable energy industry is more labor-intensive. This means that, on average, more jobs are created for each unit of electricity generated from renewable sources than from fossil fuels. renewable energy already supports thousands of jobs in the United States. For example, in 2011, the Solar Energy industry directly employed 75,000 full-time-equivalent employees in a variety of capacities, including manufacturing, project development, construction and solar panel installation, operations and maintenance, transportation and logistics, and financial, legal, and consultation. With more employment, people become happier around friends and family and are proven to have better lives when employed.
