Making of Solar Panels
By Green Guest | July 15, 2009
Solar panels have given us the ability to turn the light of our sun into usable electric energy. The construction process of a solar panel is performed either by a crystalline process or by an amorphous process. The latter being preferred for various merits to its counterpart crystalline panels. Flexibility, less fragility, and greater efficiency and minimal cost are the reasons which supports the amorphous panels as being a better choice for consumers. The advent of amorphous panels may contribute in a reduction of our fossil fuel dependency, and thus stand as a potent potential energy source for future hi-tech devices.
Amongst some in the eco-conscious community, solar panels for energy are being considered as a staple source of energy. Solar panels with an ability to convert solar radiation into usable energy are appreciated for solar powered homes. But only a few ever know the diligence and delicate process demanded for creating a solar panel. And this delicate process is the main cause impeding the development of solar panels further than they are right now. Though it should be noted that many companies and universities are studying ways to maximize the light of our sun by increasing the energy produced by each solar unit, their weight and ease of manufacturing, and bringing down their cost.
There are two main categories of panels, with one being the crystalline type of solar panel. In this kind of panel, silicon which is the main component in all solar panels, are used in the formation of thinly sliced wafers requiring essential polishing for remove any imperfections. The wafer is then coated with a phosphorous layer and then it is heated. While the diffusion of phosphorous takes place into the silicon, a thin conductive grid is used to conjoin the wafer. Protective glass is used to bond the wafers, the glass being a thin layer and with use of thermally conductive cement, it is sealed to its supports. Extensive use of precise automatic tools and vacuums are carried for ensuring that the wafers position correctly as per specifications. Greater care is taken for ensuring that the wafers are flawless so as to make them able to generate the most possible electricity.
Because of the manufacturing hurdles and fragile nature of crystalline panels, the second type known as amorphous solar panels comes further to the forefront of solar panel innovation. The making of crystalline panels differs greatly from its counterpart crystalline panels. The manufacturing process comprises of diffusing vaporized silicon into thin layers so as to render flexibility and lessen fragility of the panels. These layers possess a better ability to absorb a greater light spectrum and thus contribute larger amounts of energy under the same light conditions.
As costs come down and the need for alternative energy sources continually increases, the use of solar panels for harnessing the power of the sun will only grow. Many new homes and businesses are being built with solar power panels for their energy needs. Sometimes the energy generated is more than what is needed and this excess is added to the local power grid bringing extra revenue to the solar panel owner while helping to quickly pay off the initial cost to install solar energy panels.

[...] Solar panels hit presented us the knowledge to invoke the reddened of our solarise into disposable automobile energy. The cerebration impact of a solar commission is performed either by a polycrystalline impact or by an unformed process. The latter existence desirable for different merits to its duplication polycrystalline panels The rest is here: Making of Solar Panels [...]
