The Basics Of Solar Energy

Solar power can be used for domestic, industrial, and municipal purposes. Solar power can be derived from the rays of the sun. Solar power can be classified into three basic categories: solar thermal energy, photovoltaic power, and solar electricity. This article briefly discusses the characteristics of each type of power.

Direct Current: This is the most efficient of all solar energy sources. Photovoltaic cells are arranged in series, with each series cell having a thin photovoltaic film on its surface. Solar cells convert solar energy into direct current electricity by conduction through the photoelectric effect.

Direct-Conversion And Combined Systems

 In the photovoltaic type, PV cells are assembled on a semiconductor wafer, which is then coated with a material that has been treated with electrons. When electricity is applied, the electrons transfer their energy to the silicon wafer, causing a change in the voltage. The electrical current generated is then routed to lead-based electrodes. 

To prevent the generation of large amounts of alternating current, photovoltaic panels are designed to have just two main ways to generate electricity. These types of systems are called first or second-hand, direct-conversion, and combined systems.

Electromagnetic Radiation

There are two primary sources of solar energy, which are electromagnetic radiation and sound. Electromagnetic radiation is primarily produced through cosmic rays, x-rays, and high frequency radio waves. 

Electromagnetic radiation can also be emitted from the Sun, through exploding stars and other explosions, gamma-ray bursts from space, and through nuclear fission. Microwaves and ultraviolet rays also produce significant amounts of electromagnetic radiation, as does cosmic ray interaction with the water in the solar system.


Another renewable energy source that works in conjunction with the photovoltaic effect is sound. Unlike electromagnetic radiation, sound can be produced by anything, including the movement of air and water, the beating of the drums in an auditorium, the creaking of wood, and the rushing of water through the pipes in your home. Some forms of sound are produced by the wind, while others are made by animal and human voices. The majority of sound energy is converted into other forms of radiation and heat. Sound is a powerful renewable energy resource that has been used for millennia throughout the world.

Humans have harnessed the power of sound for ages, using it for war, music, rituals, and even prayers. The sun provides us with an endless source of solar energy sources that can never be exhausted. There is an estimated 2 trillion watts of usable energy stored in the amount of sunlight available each day. We could easily meet our global energy needs with the power of the sun. If only we knew how to harness that power. The sun provides us with an unlimited source of clean energy. We just need to learn to harness that power properly, and convert it into something that can be used well. 


To get started on your solar energy definition, you should understand a little bit about the sun. It is classified as a “cosmos” because it contains countless individual sunspots, each with their own temperature, energy output, and life cycle. The sun is very likely the only known planet that contains usable free energy, waiting to be tapped into by humans. When sunlight hits the surface of the earth, light and heat energy are released, converting the light into heat energy and electricity. The actual process of conversion is a complex one, involving convection, radiation, and absorbed heat. With this information in hand, you can now start to learn about what solar energy is, how it works, and how you can make your own solar panels to take advantage of this free source of electricity.
