Learn About Solar Power And Its Applications
Understand the workings of solar power and understand how it can help us by coming in use in various energy generating applications.
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?
The sun is the actual source of much of the power that is generated by man. Solar power is full of potential and has many benefits, some obvious and a few others that are not so apparent. In fact, the sun has always been benefiting mankind in many ways from time immemorial and is continuing to do so even now. 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 many sophisticated means of capturing solar energy for use in various applications. Devices like photovoltaic cells are implemented for converting solar power into electricity. Other modern equipment that are powered by the sun include solar chimney, solar cells, solar water heaters, solar thermal devices and so on. All these devices use solar radiation for their operation and offer unmatched economy and convenience. However, the actual performance of these applications may vary greatly depending on surrounding factors.
Broadly speaking, solar technology can be categorized into two main types - active and passive. This classification is based on the way solar radiation is captured, and converted into the desired form of energy and distributed. The various solar devices mentioned above fall under the active solar technology category as they involve the direct conversion of solar radiation into the required form of energy. Passive solar technologies on the other hand, cover all those materials that have favorable thermal properties and involve designing buildings and spaces with prime and proper air circulation and ample exposure to sunlight. Be it active or passive, both the forms of solar technologies serve the purpose of increasing solar power conservation. Active solar technologies encourage the production of solar energy while passive solar technologies lessen our dependence on non-solar power. No other means of generating power save solar power helps us so much in preserving and protecting our environment. This is achieved by virtue of the clean and 'green' nature of solar energy.
The applications of solar power
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.
The list of solar applications continues with its use in agriculture. The power of the sun has along been used by farmers everywhere 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. Other applications of solar power in agriculture include powering water pumps, drying crops, and more. 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 thus goes on 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. Such reactions can be broadly divided into thermo-chemical and photo-chemical reactions depending upon how solar energy is used in the process. Finally, there's the big economical advantage of using solar energy which is probably the cheapest source of energy!
You can consider setting up a solar energy system right at your own residence. The Internet has some very good resources to help you set up a system to start using this secret alternative energy. A step-by-step guide, which clearly walks you through all the necessary steps, can prove to be really useful, especially if you are new to solar energy. With this information you can do it quite easily and of course, safely.
