Types of Solar Panels

7 Different Solar Panel Types.

Did you know the world’s energy needs for 1 year can be covered by the sun generating energy for only 1 minute? In fact, within 24 hours the Sun is Capable to generate more energy than the entire world's population would consume in 27 years.
Our sun is therefore not only a truly reliable and uncompleted source of energy, but also a very free, efficient and efficient source if the selected types of solar panels and the environment are perfectly matched. Such promising prospects have grown in an industry that has put a great deal of effort into developing efficient techniques for generating, using and storing the energy of the sun by using different types of solar photovoltaic panels and converting the sunshine into valuable and expensive power. 

When you look at the graph, it is easy to see the rapid increase in solar PV electricity generation in the last few years in the United Kingdom. Solar PV electricity generation increased by around 87 percent in one year (2014-2015).

Some people know about the different technologies for solar energy, such as solar thermal and solar water heating, on the market.
Where these alternatives to conventional solar PV panels are mainly used for water heating, the following paragraphs provide a more detailed introduction to the various types of solar PV panels used for green and clean electricity generation. Several decades of research, hard work and development have led to the wide range of solar photovoltaic panels that are now readily available on the market. 
This topic offers some useful information on the most popular solar panels and special types of solar PV panels to provide a broader picture.

How to classify the various solar panels.

Various PV solar panel types Deliver various needs and purposes. See the solar panel manual, which you can find easily, for an overview of different types of solar panels, for a detailed overview.
Due to the fact that sunlight can be used differently on the Earth or in space, it is important to choose a solar panel of one type over another in this situation.
Differentiating between different types of solar panels often implies differentiation between single and multi-connect solar panels or first, second or third generation solar panels. The number of layers on the solar PV panel that observe the sunlight vary between single and multi-junction where the classification by generation focuses on the material used and efficiency of the various types of solar PV panels. 

Solar Panel's 1st Generation.

These types of solar panels are conventional and are mostly used in conventional environment and are made of Mono-crystalline silicone or poly-silicon.

  •        Mono-crystalline PV (Mono-SI)

It is the purest type of solar panel. You can recognize them easily from the uniform dark look and the circular edges. The high purity of the silicone causes this type of solar panel to have one of the highest efficiency rates, the latest being above 19 percent. Mono-crystalline panels have a high output of power, occupy less space and last longer. Of course, they are also the most expensive in comparison with other panels. Another advantage is that high temperatures tend to affect them slightly less than polycrystalline. 

  •        Polycrystalline Solar Panels (Poly-SI)

You can quickly distinguish these panels because these types of solar panels have squares, the angles of the cells are not cut and the color is blue. They are made from raw silicone melting, which is a faster and cheaper process than mono- crystalline PV panels.

This leads to a lower price but also a lower efficiency (approximately 16 percent), a lower space efficiency and a shorter lifespan, as hot temperatures affect them to a greater extent. The differences between mono-crystalline and polycrystalline types of solar pv panels are not so significant, however, and the choice depends entirely on your particular situation. The first option offers a slightly higher space efficiency at a slightly high price, but basically power outputs are the same. 

Solar Panel's 2nd Generation.

These cells are various types of thin film solar cells and are mainly used in photovoltaic power plants, which are integrated in buildings or smaller solar systems.

  •         Thin Film Solar Cells (TFSC)

If you are looking for a cost-effective option, thin film is the right choice. Thin film solar panels are produced by placing one or more films of photovoltaic material on a substratum (such as silicone, cadmium or copper). These types of solar panels are the easiest to produce and economies of scale make them cheaper than the alternatives because they require less material for their production.
They are also flexible, which offers many alternatives and is less affected by high temperatures. The main problem is that they take up more space and are usually unfit for residential facilities. They also have short-term guarantees because their lifetime is less than the mono-crystalline and poly-crystalline PV module types. They can, however, be a good option to choose between the various types of solar panels with more space. 

  •     Amorphous Silicon Solar Cell (A-Si)

Have you ever used a calculator with solar power? Yes? Yes, yes? You've seen these kinds of solar panels before. The amorphous solar silicone cell is one of the various types of solar pv panels, which is mainly used in such calculators. This solar panel type uses a three-layer technology, the best of the thin film solar cells.

Just to give a brief idea of what thin means, we are talking about a thickness of 1 micrometer in this case. With an efficiency rate of only about 7 percent, these cells are less efficient than crystalline silicone cells with an efficiency rate of around 18 percent, but the advantage is that the A-Si cells are nearly low in cost.

Solar Panel's 3rd Generation.

Solar panels of the third generation include a variety of thin film technologies, but most of them are still in the research and development phase. Some use organic materials to generate electricity, while others use inorganic substances (CdTe, for example).

  •      Bio-Hybrid Solar Cell

Biohybrid solar cells are one of the types of solar panels still in the research and development phase. It was discovered by a research and development team at the University of Vanderbilt. The idea behind the new technology is to use photo system 1 to emulate the natural photosynthesis process. In case you want to learn more about the biohybrid solar cell in detail, read more about it in the American Journal of Optics and Photonics. It explains more detailed how these solar cells works. Many of the materials being used in this cell are similar to the conventional methods, 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)

This PV technology uses cadmium Telluride, which allows solar cells to be manufactured at a relatively low price and thus shortened payback time (less than a year) among the various types of solar panels.This is the one that requires the least water for production of all solar energy technologies. With a short energy recovery time in mind, solar cells from CdTe will maintain the lowest possible carbon footprint. Cadmium Telluride 's only disadvantage is its property of being poisonous, ingested or inhaled. This is one of the largest barriers in Europe in particular, as many people worry that the technology underlying this type of solar panel will be used.

  •    Concentrated PV Cell (CVP and HCVP)

Concentrated PV cells produce power just like conventional PV systems. These multi-junction solar panel types have an efficiency rate of up to 41 percent, which is the highest of all PV systems to date.

Compared to other types of solar panels, curved mirror surfaces, lenses, or even cooling system are used to link the sun and increase the efficiency of these CVP cells. The name of these cells is related to what makes them so efficient.
CVP cells have thus become one of the most efficient solar panels with up to 41 per cent high efficiency and high performance. The fact remains that solar panels of such CVP only have a perfect angle to face the Sun. A solar tracker inside the solar panel is responsible for following the direction of the sun in order to reach these high efficiency rates.
