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.
Because man started building homes, sunlight played a major influence in the design. Actually, even in the a lot more advanced urban planning method of the Ancient Chinese and Greeks, the orientation from the buildings is as much as possible directed towards where 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 however when they build, they had been constructing 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 being the conventional sources of power became a lot more costly, homeowners had been once again turning to the sun for energy requirements.
Because the 1950’s, harnessing the sun’s rays has been developing and today the solar cell products has achieved very efficient levels that modern (so-called green home) designs apply the sun’s energy to supply power for the home.
While solar energy is free, the device which will convert it to run our appliances. To supply solar energy for the home, solar cells called photovoltaic created from semi-conducting materials, are grouped into modules. These solar panels are mounted on rooftops, yards or open spaces wherever it can capture 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 generally 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 power, pumps are often used – circulating water in the cells. The water goes into a storage tank wherever 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 development in solar energy though, the use of this technology isn’t sufficient to supply energy 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 from the traditional 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 good starting point. Homeowners that feel that the high price of powering their houses through solar power, is justified when compared to the price that’s now being paid for traditional electrification method where horrendous amounts of CO2 are becoming dumped into the atmosphere just to generate a pitiful amount of electricity.
Nevertheless, 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 technique will be made widely obtainable for those who prefer it as its sole power source.
