What is Solar Energy? And How It Works

Before going fully into viewing how solar panels work, it is convenient to define exactly what solar energy is.

The origin of solar energy is produced by a nuclear fusion reaction and because of the conditions of intense gravity to which it is exposed. The sun, which is composed mostly of hydrogen and under certain circumstances, melts to produce helium.

How do solar panels work

This process releases tremendous amounts of electricity that can be used for residential and commercial applications.

The Earth, which is relatively close to the sun, receives its energy and does this in various ways. Thus, the air and magnetosphere filter a lot of the damaging solar radiation but allow throughout the wavelengths corresponding to infrared and visible light. In this manner, what we get the most is light and heat.

Therefore, solar energy has become one of those engine functions for life as we know it. The sun’s beams promote the most varied effects on the world’s surface: winds, cloud formation, and rain or climatic changes around the globe.

Man has wanted to seek and construct very diverse ways to take advantage of the energy and turn them into the support of life on Earth. Because of this, the technology to extract this energy from the sun and transform it into energy for human use has been promoted, to use it like electricity and warm water, among several other uses.

When talking of solar power as renewable energy (click here to contact green energy suppliers directly), we must also mention the fact that we have transducers that enable converting a variety of kinds of pure energy to energy usable by man. The most used is power from solar energy.

To transform the sun’s energy into energy that we can apply to our daily lives, we will need a photoelectric cell. It is an electronic device that allows light energy to be changed into electrical energy, by taking advantage of a process called the photoelectric effect.

Nowadays, double-sided photovoltaic cells have been already used which, with the assistance of reflective surfaces, can double the efficacy and enlarge the surface exposed to sunlight. These cells are referred to as photovoltaic solar panels and use technology as complex and precise as it is complicated.

Obviously, at the moment hardly any companies in the world possess the capacity and technical resources to be able to produce them.

These photovoltaic cells are combined in several distinct ways to achieve voltage and power. In this manner, it may be achieved that solar energy ends up being converted to energy that can be consumed.

Not surprisingly, we know that a photovoltaic cell to be the tiniest module made from semiconductor material using a P-N intersection as well as capable of producing electricity. The photovoltaic panel would be the set of cells to the appropriate support and that has the coatings which protect it from atmospheric agents.

Different types of solar panels exist, which we may currently find on the market. We need to buy best solar panels from the best company for our homes and offices to get more benefits from the solar energy system. 



Solar panels have a collection of advantages that make them one of the excellent alternatives for the future. These are the advantages of solar panels:

Inexhaustible – First of all, their most obvious advantage is that they are capable of transforming the sun’s rays into energy. It is, thus, entirely renewable and inexhaustible energy. The sunlight’s energy does not run the danger of disappearing. Therefore, there’s no need to worry that it is going to operate out, at least in many millions of years.

Less waste – Using solar panels, the problem of waste storage could be ended. Not to mention that the storage of waste caused by nuclear energy.

The decline of natural disasters – With solar energy, natural disasters such as the ones that happened in Chernobyl or Fukushima nuclear power plants and others that recur from time to time would wind. Thankfully, modern Chernobyl has slowly been getting safer as radiation levels drop – people even live there now.

Self-consumption – Solar panels would allow, for example, access to electricity in less-favored regions, where the power lines do not reach.

Production – All these panels could be installed on a large scale, to produce electricity in massive quantities, or in the kind of small home installations, to serve as energy. They can also serve to reduce public spending lighting, through solar street lights, for example. The chances are multiple.

Another advantage is that they can also help significantly in reducing your electric bill . But before going solar think twice, in case you are a business owner in Texas and want to choose the best and most affordable energy plans we recommend you visiting the HomeEnergyClub website where you can get access to the low business electricity rates Texas that are cutting the bills.

Simple installation and minimal maintenance – Solar panels are relatively easy to install and do not need laborious maintenance. It also needs to be said that they usually have a helpful life of about 20 years.


The time now for the advantages and disadvantages of solar panels:

Little implanted energy – The main drawback of solar panels is the solar energy is a bit implanted energy and, most importantly, little supported by the large energy companies.

Minimum market share – In certain nations, among which Spain could be depended, solar energy represents a minimal market share.

Detailed location – One of the few disadvantages which can be cited is that the panels need a particular place and position to function at full capacity and aren’t as helpful in areas where there is less sun.

Initial investment – The installation of solar panels or panels suggests a reasonably high initial outlay (solar panels typically cost around 7,000 euros, but each is cheaper and much more efficient). But for domestic use, it is proven that these panels could be amortized within a period of approximately 7 or 10 years in most.

Visual impact – Finally, it is correct that solar panels have a significant impact on the landscape; hence they are usually located in virtually abandoned (and desert) regions, too for obvious performance reasons.

It is also true that aesthetically it isn’t too pleasant at a building or within a country house. Still, when it is in favor of energy efficiency and the environment, it may not be such a significant annoyance.
