Mankind has totally relied on the sun’s energy before the discovery of fossils fuels. A several photonic fusions happening every now and then on the sun’s surface can be attributed as a primary source of solar energy. Utilising this solar energy, you can generate solar power by converting it into electrical energy. And how does solar power work? It not only works but also makes many useful things run!
The simple yet brilliant mechanism!
Sun’s energy is used and reused in every single way to develop solar power. The heat and light components generated by fusion of particles in sun can be an excellent source of deriving electrical energy! Semiconductors upon receiving sunlight gets excited and electron hole pairs are generated. Upon collection in huge numbers these pairs can be separated and collected in the form of flowing charge or what we call as electric current! This electric current is used to power a lot many solar power equipped devices. So how does solar power work can be answered in very simple way that is by converting thermal and chemical energy into electrical and mechanical energy.
Who was the father of this principle??
Edmund Becquerel was the first to study and discover essence of luminance, its ability to be converted into electric signals etc. With contribution from discoverers of solar cells, Albert Einstein, Fuller, Pearson and many, the world is today able to use solar panels to tap renewable energy from the sun! They were the ones who actually answered the question as to how does solar power work.
Why at all was it important for us??
Being fathers of modern day science, they could predict the dependency on renewable resources like the energy of the sun, wind, water in near future. Also their love for science and its various subjects like magnetism, luminance, and electro chemistry was the main fuel driving them towards finding answers to such vital questions.
Theory behind generation of solar power
Photons use the photovoltaic effect to generate solar power. Thin, strong sheets or panels fitted with semiconductors must be kept dry and moisture free to reap the best benefits. These photons are exciting molecules which upon hitting the semi conductor particles like silicon and aluminum never fail to get them charged. Upon charging small holes are developed on the molecular level which is then separated as per their charges, collected and stored to be duly used as current. Kilowatt hours generated from each panel depend on its size, amount of sunlight received, the quality of its semi conductor and angle to the sun.
On an average a voltage of 240 to 320 is expected to be generated and as per standards almost eight thousand kilowatt hours are required yearly to fulfill needs on daily basis! The production cost is practically free except some installation charges incurred in the beginning! Installers and dealers are these days offering exciting offers with panel prices going down and taxes being subsidized by the government. So how does solar power work? It is by increasing our daily savings on electricity bills!!
