SOLAR PANEL IN QATAR
A solar panel is a flat construction resembling a window, built with technology that allows it to passively harvest the heat of the sun or create electricity from its energy through photo-voltaic.
Passive solar panels include those used to heat water for home heating and to provide hot water on tap. Most commonly, photo-voltaic are assumed when speaking of solar panels. Photo-voltaic solar panels use positively- and negatively-doped silicon working in conjunction with conductors on the alternately charged surfaces.
Electricity is created when photons strike the surface and excite electrons to the point that they leave their valence. Solar panels are increasingly in popularity as solar power has reached price parity with oil and, simultaneously, more and more jurisdictions mandate the use of solar panels or other renewable energy sources in construction of new buildings.
Solar power is clean energy. There are no byproducts or harmful pollutants released into the atmosphere when generating solar electricity. While traditional electricity sources require the burning of coal or fossil fuels, solar panels use solar energy immediately, without the need for combustion. – The sun fuels solar panels, so there is no need to worry about rising fuel prices if your home is powered by a solar electric system. Free, clean energy is always available, so solar panels simply provide peace of mind.
Solar energy is free. It has always been, and always will be free. Other sources of energy, on the other hand, cost money, and the price of conventionally supplied electricity continues to rise over time.
You can pay off your home and your car, but you may not have considered owning your electricity source. Solar power puts you in control, so that you will not have to pay the utility company every month. Not only is this good for your wallet, you can also be assured that your household’s carbon footprint has been significantly reduced by switching to solar power.
Distinguishing between different types of solar panels often means differentiating between single – junctions and multi-junctions solar panels or first , second , or third generations. Single-junction and multi-junctions differ in the number of layers on the solar panel that will observe the sunlight, whereas the classification by generation focuses on the materials and efficiency of the different types of solar panels. 1st Generation Solar Panels These are the traditional types of solar panels made of mono-crystalline silicon or poly-silicon and are most commonly used in conventional surroundings. Mono-crystalline Solar
This type of solar panels (made of mono-crystalline silicon) is the purest one. You can easily recognize them from the uniform dark look and the rounded edges. The silicon’s high purity causes this type of solar panel has one of the highest efficiency rates, with the newest ones reaching above 20%.
You can quickly distinguish these panels because this type of solar panels has squares, its angles are not cut, and it has a blue, speckled look. They are made by melting raw silicon, which is a faster and cheaper process than that used for mono-crystalline panels.
2nd Generation Solar Panels
These cells are different types of thin film solar cells and are mainly used for photo-voltaic power stations, integrated in buildings or smaller solar power systems.
Thin-Film Solar Cells (TFSC)
If you are looking for a less expensive option, you might want to look into thin-film. Thin-film solar panels are manufactured by placing one or more films of photovoltaic material (such as silicon, cadmium or copper) onto a substrate. These types of solar panels are the easiest to produce and economies of scale make them cheaper than the alternatives due to less material being needed for its production They are also flexible—which opens a lot of opportunities for alternative applications—and is less affected by high temperatures. The main issue is that they take up a lot of space, generally making them unsuitable for residential installations. Moreover, they carry the shortest warranties because their lifespan is shorter than the mono- and polycrystalline types of solar panels. However, they can be a good option to choose among the different types of solar panels where a lot of space is available.
Amorphous Silicon Solar Cell (A-Si)
Have you ever used a solar powered pocket calculator? Yes? Then you have definitely seen these types of solar panels before. The amorphous silicon solar cell is among the different types of solar panels, the one that is used mainly in such pocket calculators. This type of solar panel uses a triple layered technology, which is the best of the thin film variety. Just to give a brief impression of what “thin” means, in this case, we’re talking about a thickness of 1 micrometer (one millionth of a meter). With only 7% efficiency rate, these cells are less effective than crystalline silicon ones—that have efficiency rate of circa 18%—but the advantage is the fact that the ASi-Cells are relatively low in cost.
3rd Generation Solar Panels
3rd generation solar panels include a variety of thin film technologies but most of them are still in the research or development phase. Some of them generate electricity by using organic materials, others use inorganic substances (CdTe for instance).
Biohybrid Solar Cell
The Bio- hybrid solar cell is one of the types of solar panels that is still in the research phase. It has been discovered by an expert team at Vanderbilt University. The idea behind the new technology is to take advantage of the photosystem 1 and thus emulate the natural process of photosynthesis But only by combining the multiple layers of photosystem 1, the conversion from chemical to electrical energy becomes much more effective (up to 1000 times more efficient than 1st generation types of solar panels).
Cadmium Telluride Solar Cell (CdTe)
Among the collection of different types of solar panels, this photovoltaic technique uses Cadmium Telluride, which enables the production of solar cells at relatively low cost and thus a shorter payback time (less than a year). Of all solar energy technologies, this is the one requiring the least amount of water for production. Keeping the short energy payback time in mind, CdTe solar cells will keep your carbon footprint as low as possible. The only disadvantage of using Cadmium Telluride is its characteristic of being toxic, if ingested or inhaled. In Europe especially, this is one of the greatest barriers to overcome, as many people are very concerned about using the technology behind this type of solar panel.
Concentrated PV Cell (CVP and HCVP)
Concentrated PV cells generate electrical energy just as conventional photovoltaic systems do. Those multi-junction types of solar panels have an efficiency rate up to 41%, which, among all photovoltaic systems, is the highest so far.
The name of such CVP cells is related to what makes them so efficient, compared to other types of solar panels: curved mirror surfaces, lenses and sometimes even cooling systems are used to bundle the sun rays and thus increase their efficiency.
By this means, CVP cells have become one of the most efficient types of solar panels, with a high performance and efficiency rate of up to 41%. What remains is the fact, that such CVP solar panels can only be as efficient if they face the sun in a perfect angle. In order to reach such high efficiency rates, a solar tracker inside the solar panel is responsible for following the sun.
