Solar energy, as the name itself suggests, is sourced from that glowing ball of fire in the sky that we call the sun. What we call sunlight is actually beams of electromagnetic waves that are absorbed by the upper strata of the earth’s atmosphere. This is also known as solar radiation, carrying what is known as radiant power. Of the entire amount of solar energy reaching the earth`s surface, about two thirds get absorbed by the various water bodies, clouds and landmasses, while the rest is reflected back into space.
Commercial solar plants harness a part of this absorbed energy and converted into various other useful forms of energy, mainly electricity and heat. Both electricity and heat in the modern world are generated by modern techniques called solar power generators of various types like photovoltaic cells, solar thermals, solar heaters, solar roof tiles, solar chimneys etc.
Even as the world cries out in unison to save the planet, adopt renewable and cleaner sources of power and stop environmental pollution, it is surprising to see how much ignorant we still are about renewable energy and its real potential. The most significant fact about this phenomenon lies in realizing its true nature. Yes, it is 100% natural, completely renewable and offers a perpetual source of electricity. It is also absolutely clean in nature, emitting no harmful pollutants in the air in its wake and posing no threat to the environment.
Apart from the direct use of renewable energy like the heat needed in the colder seasons, drying clothes, absorbing vitamin D for the bones there are several other uses that are performed by capturing and machinating this wonder power by the solar power generators. Those generators find their application in a varied number of fields like lighting buildings, in architecture, agriculture, urban planning, solar vehicles and even domestic usages like cooking and water heating.
On the contrary, solar energy can actually help us realize substantial savings on our electricity consumption costs. All the expenses involved in getting it into your household is limited to the initial set up. After that, you can keep enjoying all the electricity you need at practically no cost at all.
Here are some more points to ponder. Did you know that sunlight has the potential to act as a massive source of abundant energy, enough to light up the entire planet? The amount of sunlight that falls in an hour on the earth`s surface actually surpasses the amount required by the entire world`s population in a year. In fact, the current demand for solar power is more than the amount that is being supplied by all the existing generators in the world.
So what makes solar power such a “hot” idea (no pun intended) even after all these years? The first, and clearly the most important reason, is economy. If you`ve ever wondered if there is such a thing as free energy, well, solar power is the closest you can get. The ecological benefits of using renewable energy are also tremendous. Man`s incessant need for heat and light is leading to the rapid reduction in the reserve of natural resources.
As more and more trees are being felled to supply firewood, and coal and oil reserves are aggressively tapped into, it won`t be long before mankind will be faced with a new peril of having to live on a barren planet. The salvation, fortunately, is already here. It’s an alternative power. However, while discussing the facts about solar energy let us not overlook the few disadvantages that it has.
Solar power generation requires plenty of sunlight. So it is critical to select an area that gets plenty of sunlight throughout the year, or else the entire set-up might be rendered futile. Research on these limitations is still going on and very soon there will come a time when solar power will effectively replace conventional power everywhere. It is amusing to watch Da Vinci`s 1447 dream of a solar industrialization is nearing realization after all these years!
Installing a solar panel at home is one of the best decisions you will ever take. Not only will you be happy to watch your utility 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.
