Solar energy for residential homes is nothing new. It has just been banished to the background in lieu of skyrocketing cost of property ; more moderen more advanced building materials, design and the limitation of resources.
Since man started building houses, daylight played a major influence in the design. In truth, even in the more sophisticated urban planning technique 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 might not be as intellectually complex 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 in the structure and manufacturing well lit, well ventilated spaces using the relative position of the sun to the orientation of their structures.
Recently, 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 extraordinarily 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 is not. 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 amount of sunlight.
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 basically 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 often 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’ll just the same store the heated water in to the tank.
Despite all of the development in solar energy though, the use of this technology is not enough to provide power to the entire house. The best method so far can only fulfill about eighty percent of a homes power wishes. Using solar energy for the home will still require the employment of the typical power distribution technique.
Powering the homes by solar means will still, for a bit be enlarged by a local power distribution agency. To many, this is a good starting point. House owners that feel the high price of powering their houses thru solar power, is justified when compared to the price that is now being paid for traditional electrification strategy where horrendous amounts of CO2 are getting dropped into the atmosphere solely to generate a pitiful amount of electricity.
However, due in part to the skyrocketing costs of energy, the technology for solar energy has been undergoing rapid phases of development. Gurus are assured that inside five years, powering the home through the solar system will be made widely available for people that like it as its sole energy source.
