Pros And Cons Of Solar Energy: Revealed
Find out hidden secrets about solar energy which power companies hide from you. The power to save thousands of dollars is in YOUR hands!
How do we get solar energy and what exactly is this?
The sun is the source of what is known as solar energy. It is derived from the radiant energy that is emitted by the sun. Solar energy is hardly ever used in its original form, but is often transformed into various other useful forms of energy such as electricity, heat, light, mechanical and chemical power, and used in a wide range of applications. The radiant energy is obtained from the sun’s rays which are primarily comprised of radioactive waves. Interestingly, of the entire amount of sun’s energy received by the earth, the upper layers of the planet absorb about 70% of it through the terrains, water bodies, and the clouds, while the rest is sent back into space. Solar energy, derived from this absorbed amount, is an important alternative source of power for the entire world and is something that is finding greater acceptance everywhere with passing time. In this respect, it is easy to realize the importance of learning about all the pros and cons of solar energy as we might be using it ourselves in the not-too-distant future.
Solar energy: here are the advantages and disadvantages
It is reassuring to see that solar energy is getting accepted widely by more and more people everyday and is finding newer applications and uses with every passing day. Apart from the already popular and widespread domestic use of solar power, it is also being used extensively in various other fields such as agriculture, architecture, urban planning, solar lighting, solar thermal, solar chemical, solar vehicles, cooking and so on. Based on how solar power is being used, it can be broadly divided into two classes – active solar power and passive solar power. The former is essentially all about using solar panels and photovoltaic cells to capture and convert the sun’s energy into various forms of energy, while the latter is more concerned about reducing the dependence on alternative power sources and instead, directly use the natural light and warmth of the sun by citing buildings optimally to the sun, designing well-lit and well-illuminated spaces in the buildings and so on. The fact is that solar energy has become an integral and inseparable part of our daily lives. Unfortunately, the general public ignorance about this marvelous source of power is surprising!
If one were to enlist all the advantages of using solar power, it would it a very long list indeed. The sun is a perennial source of energy with sufficient output to meet the entire planet’s energy requirements, and then have plenty of extra to spare. Solar energy is an excellent alternative source of energy and thanks to modern science and technology, it is now possible to tap into this vast resource and harness a part of it to put it to various uses. The best thing about solar energy is that it’s free, and once one has invested in setting up the system, there’s no recurring cost. As the concern over gradually dwindling natural resources (such as coal and petroleum) continues to grow, alternative sources of energy are being looked into with renewed enthusiasm. Moreover, this completely pollution-free, environment-friendly and ‘green’ source of energy is a boon to any living society and environment. Solar power offers a great deal of flexibility in allowing itself to be set up at very remote locations, such as in satellites in space, and yet produce power with amazing efficiency. This further means that solar installations can be made in rural or remote areas for more economy. Recent advancements in solar power technology has made it possible to generate appreciable amounts of power even when the sun is not shining very brightly. What’s more, the energy produced during the day allows itself to be stored for use at night or at times when the circumstances are not apparently conducive to producing solar power.
Here’s how we can gain from solar energy
All said and done, solar power, however, has its share of disadvantages as well. First, there is he question of economy. Solar panels and other related equipment are usually quite expensive. Even the cheapest solar power generator would cost one nearly a thousand. Another con of using solar power is the fact that most solar systems, even now, are not sophisticated or advanced enough to generate any appreciable amount of electricity under non-optimum circumstances. In other words, a steady supply of bright sunlight is absolutely required by most to be of any real use. Moreover, their performance is still susceptible to be affected by the presence of all the pollutants in the air. In fact, few solar power systems today are able to give 100% output. This is the reason why installing a solar power generator at a remote and rural locality makes better sense as it yields more output than in the city where the air is usually more polluted.
Solar power is really a great choice for reasons both financial as well as environmental. That is why so many people are enthusiastically considering installing a system in their homes. The best thing is that you can too. But for that you need to know where to put it up, how to install and wire it, where to get the parts and the batteries from and also the safety regulations that have to be followed. A step-by-step guide in this respect can be really helpful. You should seriously consider getting hold of one such good guide before you take the plunge into the wonderful world of solar power.
