Solar Energy – The Future of Generating Energy For The Home
Solar energy for residential homes is nothing new. It has just been confined to the background in lieu of skyrocketing cost of property ; newer more complicated building materials, design and the limitation of resources.
Since man started building houses, sunlight played a major influence in the design. In fact, even in the more sophisticated urban planning method of the Ancient Chinese and Greeks, the orientation of the buildings is as much as humanly possible directed at where it could capture the most daylight.
The ancients would possibly not be as intellectually complex then to use slogans as passive solar and thermal mass but when they build, they were building in compact proportion, employing overhangs, manufacturing insulations and building in manners that direct the airflow within the structure and producing well lit, well ventilated spaces using the relative position of the sun to the orientation of their structures.
Lately, as the conventional sources of energy became more expensive, householders were once more turning to the sun for energy requirements.
Since the 1950’s, harnessing the sun’s rays has been developing and today the solar cell technology has achieved awfully efficient levels that modern ( so-called green house ) designs apply the sun’s power to provide energy for the home.
While solar energy is free, the device which will convert it to run our appliances isn’t. To provide solar energy for the home, solar cells called photovoltaic made from semi-conducting materials, are grouped into modules. These solar panels are mounted on rooftops, yards or open spaces where it can capture the maximum amount of sunlight.
Whenever possible, the panels will be installed facing south to get the maximum out of the sunlight but tracking systems are also used to follow the direction of the sun. The solar panels collect the energy from the sunlight. The process essentially is that when the panels are exposed to sunlight, the electrons are separated form the atoms. This movement of the electrons creates electricity.
To store power, pumps are sometimes used – circulating water in the cells. The water goes into a storage tank where the power is stored, prepared to be used. Occasionally, the utilization of gravity is employed if it’ll just the same store the heated water in to the tank.
In spite of all of the development in solar energy though, the utilization of this technology isn’t really enough to provide power to the entire house. The best method so far can only fulfill about 80% of a homes power wishes. The use of solar energy for the home will still need the employment of the standard power distribution methodology.
Powering the homes by solar means will still, for a while be augmented by a local power distribution agency. To several, this is already a good start line. Homeowners that feel the high value of powering their homes through solar power, is justified when compared to the price that is now being paid for conventional electrification method where horrible amounts of CO2 are being dumped into the atmosphere just to generate a pathetic amount of electricity.
However, due partly to the skyrocketing costs of energy, the technology for solar energy has been undergoing rapid phases of development. Gurus are confident that within five years, powering the home through the solar system will be made generally available for those who prefer it as its sole energy source.
