The question “What is Solar Power” tends to mean different things depending on who’s asking. This article is going to attempt to answer the question from every perspective and level of education. Whether you want to know about the physics of the sun’s energy, interested in how this energy gets converted into useable electricity and heat, wondering whether you should get solar panels on your home or business, or are an electrician looking for whether it’s important to get solar training, we aim to answer your questions in a simple and easily understandable way.
THE PHYSICS OF THE SUN’S POWER
The sun is by far the most significant source of energy on earth, in fact, until the discovery of nuclear power, it was the only. The sun’s heat creates the different air pressures that cause the winds to blow. The energy from the sun is changed into chemical energy for plants, which in turn support animal and human life – and provide energy for our daily tasks. Even fossil fuels such as coal, oil, and natural gas, were formed as a result of decomposing plants, originally supported by the sun’s energy.
Formed 4.6 billion years ago, our sun is brighter than about 85% of stars in the Milky Way galaxy. The scale of our sun is difficult to comprehend; it is 109 times larger than earth, 93 million miles away, and it takes 8 minutes and 19 seconds for its light to reach earth. Still, enough energy hits the earth every hour to supply global energy demands for one year. The trick is harnessing it.
