Going Green With Solar Energy
Solar energy for home homes is nothing new. It has just been relegated to the background in lieu of skyrocketing cost of real estate ; more recent more sophisticated building materials, design and the limitation of resources.
Since man started building homes, sunlight played a major influence in the design. In fact, even in the more advanced urban planning methodology of the Ancient Chinese and Greeks, the orientation of the buildings is as much as humanly possible directed towards where it could capture the most sunlight.
The ancients might not be as intellectually complicated then to use catch phrases as passive solar and thermal mass but when they build, they were building in compact proportion, employing overhangs, producing insulations and building in manners that direct the airflow within the structure and manufacturing well lit, well ventilated spaces using the relative position of the sun to the orientation of their structures.
Lately, as the typical sources of energy became more expensive, householders were once more turning to the sun for energy wants.
Since the 1950’s, harnessing the sun’s rays has been developing and today the solar cell technology has achieved very 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 that will convert it to run our appliances isn’t. To provide solar energy for the home, solar cells called photovoltaic made of semi-conducting materials, are grouped into modules. These solar panels are mounted on rooftops, yards or open spaces where it can capture the maximum quantity of daylight.
Whenever possible, the panels will be installed facing south to get the most out of the daylight but tracking systems are also used to follow the direction of the sun. The solar panels collect the energy from the daylight. The method 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 for use. Occasionally, the utilization of gravity is used if it will just the same store the heated water in to the tank.
In spite of all the development in solar energy though, the utilization of this technology isn’t enough to provide power to the whole house. The best method so far can only meet about 80% of a homes power desires. Using solar energy for the home will still require the employment of the standard power distribution method.
Powering the homes by solar means will still, for a while be enlarged by a local power distribution agency. To several, this is a good start line. Homeowners that feel the high cost of powering their houses through solar power, is justified compared to the price that is now being paid for conventional electrification method where horrendous amounts of CO2 are getting dropped into the atmosphere solely to generate a pitiful quantity 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 inside five years, powering the home through the solar system will be made generally available for those that prefer it as its sole energy source.
