Solar Energy – The Future of Generating Energy For The Home
Solar energy for residential houses is nothing new. It has just been confined 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, daylight played a major influence in the design. In fact, even in the more advanced urban planning technique of the Ancient Chinese and Greeks, the orientation of the buildings is as much as feasible directed towards where it could capture the most sunlight.
The ancients might not be as intellectually sophisticated then to use catch phrases 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 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 dearer, owners 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 ( supposed 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 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 sunlight. The method fundamentally is that when the panels are exposed to daylight, the electrons are separated form the atoms. This movement of the electrons creates electricity.
To store power, pumps are frequently used - circulating water in the cells. The water goes into a storage tank where the power is stored, ready for use. Infrequently, 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 strategy so far can only fulfill about eighty percent of a homes power wishes. Using solar energy for the home will still need the use of the conventional power distribution methodology.
Powering the homes by solar means will still, for a bit be augmented by a local power distribution agency. To many, this is a good starting point. Homeowners that feel that the high price of powering their houses thru solar power, is justified compared to the price that is now being paid for traditional electrification method where horrendous amounts of CO2 are getting dumped into the atmosphere simply to generate a pathetic amount of electricity.
However, due in part to the rising costs of energy, the technology for solar energy has been undergoing rapid phases of development. Experts are assured that within five years, powering the home through the solar system will be made widely available for people that like it as its sole energy source.
