How do we get solar energy and what exactly is this?
Solar energy, as the name itself suggests, is derived from the sun and is sourced from the radiant energy that is emitted by the sun. Solar energy thus obtained is transformed into various other useful forms of energy such as electricity, heat, light, mechanical and chemical power, and used for a most diverse range of purposes. The radiant energy is emitted through the rays of the sun which are primarily made up of radioactive waves. Of the entire amount of sun’s energy incumbent on the earth’s surface, the upper layers of the planet usually absorb around 70% of it through the various water bodies, landmasses and the atmosphere, while the rest is reflected back into space. Solar energy is an important alternative source of power for today’s world and is finding wider acceptance everywhere with every passing day. In this respect, it is of much importance to learn about all the pros and cons of solar energy.
Solar energy: Understanding the advantages and the 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!
The advantages of using solar energy are far many than the handful of disadvantages that it might have. The sun, which is a gigantic storehouse of energy, can act as an excellent alternative source of energy. Modern science and technology has made it possible for us to tap into this vast resource and harness the sun’s energy to put it to various uses. Solar energy is for free, and once one has invested in setting up the system, there’s no recurring cost. As long as the sun shines, one can keep enjoying its energy for free without entailing high costs or endangering the environment. As the concern over gradually diminishing natural resources continues to grow, alternative sources of energy are being looked into with renewed enthusiasm. Moreover, this environment-friendly and ‘green’ source of energy is a boon to our already heavily polluted environment. Solar power has the ability to produce electricity at remote locations, for example, the satellite in the space is catered by high efficiency photovoltaic or solar cells that are not connected to any grid. This also supports installation of solar cells in rural or remote areas which is actually more economic than the usual high voltage wire installation. 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.
How to gain from solar energy?
Let’s take a look at some of the disadvantages of using solar power. The most serious complaint against its use is the high cost associated with it. Solar panels and other related equipment are usually quite expensive. Even the cheapest of solar power generators would easily cost one no less than a grand. Another problem of using solar power is the fact that most solar systems are not yet capable of generating sufficient amounts of electricity under less than optimal circumstances. In other words, a steady supply of bright sunlight for a fairly long stretch of time is something that is absolutely required by most solar systems today to be of any real use to us. Moreover, their performance can get seriously affected by the presence of pollutants in the air. In fact, few solar power systems today are able to give 100% output because of this reason. This is also the reason why installing a solar power generator at a remote locality usually makes better sense as it yields more output than in the city where the level of pollution is higher.
Solar power brings us numerous advantages. It saves the environment, it lowers our bills, it is fully sustainable, and it is quiet and clean. That is why so many people are having them installed every day. While solar power systems have become simpler to install, easier to procure and definitely more affordable than before, it might still challenge somebody who is new to the subject with its intrinsic complications. A step-by-step guide in this respect can be really helpful. You should seriously consider getting hold of one such good guide to ensure a trouble-free installation.
