Solar energy for residential houses is nothing new. It has just been relegated to the background in lieu of rising cost of real estate; due to more sophisticated constructing materials, layout and the limitation of resources.
Since man started constructing homes, sunlight played a major influence in the design. Actually, even in the a lot more sophisticated urban planning technique of the Ancient Chinese and Greeks, the orientation from the buildings is as much as possible directed towards wherever it could capture one of the most sunlight.
The ancients may not be as intellectually sophisticated then to use catch phrases as passive solar and thermal mass nevertheless when they build, they were building in compact proportion, employing overhangs, producing insulations and building in manners that direct the airflow through the structure and producing well lit, well ventilated spaces using the relative position from the sun to the orientation of their structures.
Recently, as the traditional sources of energy became more expensive, homeowners were once again turning to the sun for power requirements.
Because the 1950’s, harnessing the sun’s rays has been developing and these days the solar cell products has achieved very efficient levels that modern (so-called green house) designs apply the sun’s power to provide energy for the home.
Whilst solar energy is free, the device which will convert it to run our appliances. To supply solar energy for the home, solar cells known as photovoltaic created from semi-conducting materials, are grouped into modules. These solar panels are mounted on rooftops, yards or open spaces where it can get the maximum amount of sunlight.
Whenever possible, the panels is going to be installed facing south to obtain one of the most out of the sunlight but tracking systems are also used to follow the direction of the sun. The solar panels collect the power from the sunlight. The process basically is that when the panels are exposed to sunlight, the electrons are separated form the atoms. This movement of the electrons creates electrical power.
To save energy, pumps are often used – circulating water in the cells. The water goes into a storage tank where the power is stored, ready for use. Occasionally, the use of gravity is employed if it will just the same store the heated water in to the tank.
In spite of all the improvement in solar energy though, the use of this technology isn’t enough to provide power to the whole home. The best technique until now can only fulfill about 80% of a households energy needs. The employment of solar energy for the home will still need the use of the traditional energy distribution technique.
Powering the homes by solar means will still, for a while be augmented by a local power distribution agency. To many, this is already a great starting point. Homeowners that feel that the high price of powering their houses via solar power, is justified when compared to the cost that is now becoming paid for conventional electrification method where horrendous amounts of CO2 are becoming dumped into the atmosphere just to generate a pitiful amount of electricity.
However, due in part to the rising costs of power, the technologies for solar energy has been undergoing rapid phases of improvement. Experts are confident that within five years, powering the home through the solar method is going to be created widely obtainable for those who prefer it as its sole energy source.
Lastly, you got to check out the Energy Saving method that save the earth and my bill too. I didn’t know that I can make my own solar panel that only costs me less than one thousand dollar.
