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 advanced building materials, layout and the limitation of resources.
Solar energy for residential houses is nothing new. It has just been relegated to the background in lieu of rising price 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. In fact, even in the more advanced urban planning method from the Ancient Chinese and Greeks, the orientation of the buildings is as much as possible directed towards wherever it could capture 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 had been constructing in compact proportion, employing overhangs, producing insulations and constructing in manners that direct the airflow within the structure and producing well lit, well ventilated spaces using the relative position from the sun to the orientation of their structures. These days, as the traditional sources of energy became a lot more costly, homeowners had been 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 technological innovation 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 which will convert it to operate our appliances. To supply solar energy for the home, solar cells known as photovoltaic made from semi-conducting materials, are grouped into modules. These solar panels are mounted on rooftops, yards or open spaces wherever it can get the maximum amount of sunlight. Whenever possible, the panels is going to be installed facing south to obtain the most out of the sunlight but tracking systems are also used to follow the direction from the sun. The solar panels collect the power from the sunlight. The process simply is that when the panels are exposed to sunlight, the electrons are separated form the atoms. This movement from the electrons creates electrical power. To store power, pumps are frequently used - circulating water in the cells. The water goes into a storage tank where the energy is stored, ready for use. Sometimes, 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 sufficient to provide energy to the whole house. The best technique so far can only fulfill about 80% of a households energy needs. The employment of solar energy for the home will still require the use from the conventional power distribution method. Powering the homes by solar means will still, for a whilst 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 energy, is justified when compared to the cost that is now being paid for conventional electrification technique where horrendous amounts of CO2 are being dumped into the atmosphere just to generate a pitiful amount of electrical power. Nevertheless, due in part to the rising costs of energy, 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 technique will be made widely available for those who prefer it as its sole power source.

I didn't know that I can make my own solar panel that only costs me less than one thousand dollar. |
