Do you really know what solar power is? Are you aware of the various ways in solar power can be used to help us. Discover hidden facts here.

What exactly is solar power and how does this work?

The sun, with its abundant energy reserve, is such an excellent alternative source of energy. Modern science and technology has made it possible for us to tap into this vast resource pool and harness its energy to put it to various uses. Using solar energy does not cost a thing and it is virtually free. Once one has invested in setting up the initial system, there’s no recurring cost. The bottom-line is, as long as the sun shines, one can keep enjoying its energy for free without entailing high costs or endangering the environment. The need of the hour is to produce abundant quantity of ‘green’, renewable and low-cost energy in order to stop putting excessive strain on our already dwindling reserve of natural resources such as coal and petroleum. The time to unleash the power of solar energy in our lives is now. Let’s take a closer look.

How can solar power help us?

That great ball of fire up in the sky that we call the sun is the ultimate source of much of the power that is generated and used by man. Solar power is full of potential and has many benefits of which some are obvious and a few others that are not so easily realized by us. In fact, the sun has always been benefiting mankind in many ways from the dawn of history. No other source of power save solar energy offers so much goodness without causing any harm to us or the environment. Modern science has given us some excellent means of capturing solar energy for use in various applications. By using ingenious devices like photovoltaic cells and solar panels we can easily convert solar power into useful electricity. Today, one comes across an array of equipment and appliances that are powered by the sun like the solar chimney, solar cookers, solar water heaters, solar thermal devices and so on. All these devices use solar radiation for their operation and also offer unparalleled savings and a whole new degree of convenience. However, the actual performance of these applications may vary greatly depending on some incumbent factors.

To cut a long story short, solar technology can be broadly categorized into two main types – active and passive. The basis of this classification is the way solar radiation is captured, converted and distributed. The various solar devices already mentioned earlier fall under the active solar technology category as they involve the direct conversion of solar radiation into the required form of energy. Passive solar technology on the other hand, include the use of thermal and solar materials and involves designing buildings and spaces with prime and proper air circulation and ample exposure to sunlight. Active solar technologies encourage the production of solar energy while passive solar technologies lessen our dependence on non-solar power. However, no matter whether you are looking at the active kind or the passive kind, both the forms of solar technologies serve the purpose of increasing solar power conservation. In all frankness, no other means of generating power save solar power helps us so much in preserving and protecting our environment.

Finding out the areas where solar power is used

The list of all the different applications that make the use of solar power is a long one. It starts with the use of solar energy in architecture and urban planning that emphasize features like orientating buildings towards the sun, adopting selective shading, compacting proportion and so on. All these factors, when carefully matched with the corresponding climate and environment of a particular area, can lead to the construction of amply-lit spaces that enjoys the natural advantage of having a very comfortable temperature range.

And that’s not all! The list of solar applications continues with its extensive use for agricultural purposes. Farmers around the world have been using the sun’s energy to optimize and improve the productivity of crops. Techniques like fruit walls and sloping walls have been practiced to enhance solar energy collection and improve crop yields. Greenhouse is another technology applied for the specialty crops that are not really suited to the local climatic conditions and require year-round heat to reap well. Yet another significant role of solar power is in the domestic field including technologies like daylighting, solar thermals, water-heaters and cooking. Photovoltaic cells and solar panels are implemented to convert sunlight into electricity. The list further continues with numerous applications of solar energy in our daily lives as well as specialized fields like chemistry labs where sunlight is converted into chemical energy. Some rare chemical reactions require solar energy to be triggered. Finally, there’s the big economical advantage of using solar energy which is probably the cheapest source of energy! From homemade solar panels to industrial sized professional setups, solar power is ubiquitous and a great money-saver everywhere.

Installing a solar energy panel at home is one of the best decisions you will ever take. Not only will you be happy to watch your energy costs go down radically, but will also be glad to know that you are doing your bit for the environment, and ensuring a greener tomorrow for your children. The best thing about solar technology is that it can be realized with even the simplest of means. Building your very own solar system (and thereby bypassing the usual high expenses of a commercially available installation) is very much possible. A step-by-step guide, which clearly walks you through all the necessary steps, can prove to be really useful in this regard, especially if you are new to solar energy.

Learn how solar energy is generated and discover hidden secrets of gaining from this powerful energy source.

Learning about solar energy and how it is generated

The earth receives solar energy from that resplendent ball of fire in the sky known as the sun. This solar energy comes from the radiant energy of the sun which is transmitted through its rays which are composed essentially of vast amounts of radioactive waves. Solar energy, after being captured through suitable means, is hardly ever used in the form it is originally received. Rather, it is converted into different other forms of energy such as electricity, heat, light, mechanical and chemical power, to be used in a diverse range of applications. Did you know that of the entire amount of sun’s energy that falls upon the earth’s surface at any given time, about 70% gets absorbed by the upper layers of the planet, especially through its vast terrains, gigantic water bodies and the clouds, while the rest is sent back into space? Solar energy is a major alternative source of power for all of us and fortunately, mankind has been able to realize its importance in saving the planet from a possible energy crisis in the future. In this respect, it is not very difficult to realize the significance of educating ourselves about the pros and cons of solar energy as we might be using it ourselves in our homes sooner than you might think.

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!

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.

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.
