Solar energy is radiant light and heat emitted by the sun. Every day the sun radiates, or sends out, an enormous amount of energy. Thus making solar energy an endless resource and represents a clean alternative to the fossil fuels.
How is Solar Energy created?
The sun is a huge star full of gases which is mostly comprised of hydrogen and helium atoms. Within the sun's core, a process called nuclear fusion is created generating tremendous amounts of energy which is caused by hydrogen atoms in the core combining to form helium.
The nuclear reaction releases energy that travels outward from the core to the surface. During the journey to the sun's surface, the energy then goes through a transformation which by the time it is released the energy is primarily light energy. This light energy is what we refer as Sunlight.
How long does it take for Solar Energy from the Sun to hit the Earth's surface?
According to NASA, Solar Energy travels at the speed of light - 186,000 miles per second. So, it takes about 8 minutes for it to reach Earth from the Sun.
How Solar Energy is used?
The most common ways of making use of solar energy is employing a system that involves a series of solar panels and storage batteries. The solar panels collect the solar radiation and store the solar energy into the batteries. While energy is stored, it can also be used for heating and electricity.
When converted to thermal (or heat) energy, solar energy can be used to:
Solar energy can be converted to electricity in two ways:
