Solar panels are based on silicon as they choose and where to apply

Alternative sources of energy are increasingly gaining popularity among ordinary citizens, and it is not connected Only with the growth of consciousness and the struggle for the environment, but also with the constant growth of bills for utilities services. One of the most promising sources of alternative energy is our sun. In this article I want to tell you about the most common solar panels made of silicon-based.

Existing types of transducers

Classification of solar panels is done according to their structural features and the type of the photovoltaic layer. By type of device are distinguished:

1. flexible panels

2. rigid panels

The initial hegemony of rigid panels finishes and more companies produce it flexible solar panels, which are very easy to mount on almost any surface.

But on the photovoltaic layer type solar panel are divided as follows:

Next, let's talk about the panels, which are based on silicon it. So, let's begin.

Panel based on silicon and their characteristics

It is interesting

. The raw material for the production of silicon solar panels is very ordinary quartz sand, which is specially milled to a powder. But these raw materials in Russia and around the world abound, that allows us to develop this industry is almost unlimited.

Monocrystal (mono - Si)

Monocrystalline solar panel is very easy to determine in a uniform dark blue color of the plate. After all, in the production of these panels involved highly pure silicon.

The cost of such panels is the highest, but the price is offset by the highest efficiency up to 25%.

Such a high price due to the fact that the production of panels is necessary to orient all the silicon crystals in one direction, and it is quite difficult to do.

Important. The physical features of the claimed maximum performance such a plate will be given only when the sun's rays fall at right angles.

This means that on the roof of his house you such a panel, of course, be able to install, but it will be very wrong decision.

For such panels must also special equipment that will rotate them, strictly following the movements of the heavenly body.

The advantages of such panels include:

1. Efficiency at a level of 17-25%.

2. A relatively small area of ​​the placement (compared to other species, but more on that later).

3. Declared effective generation without significant loss of power equal to 20 years.

The following points can be referred to minuses:

1. High cost, but as a result of the large payback.

2. High sensitivity to surface contamination. Even small dust layer may virtually completely halt the process of generating electricity.

3. For maximum effect, require the installation of an open area and installation of the additional rotational mechanism.

Polycrystalline (multi - Si)

Polycrystalline silicon solar panels are easily distinguished by the non-uniform intensity blue color, since during its manufacture it is no longer necessary in the strict orientation of the crystal, and the elements therein arranged in a chaotic order.

This omni directional crystals not only reduces the cost of production, but also allows you to keep efficiency at the level of 12-18% in diffused light.

Since such panels are not as demanding to the orientation of the sun, they are quite well positioned on the roofs of private houses and industrial buildings.

The advantages of such panels include the following factors:

1. Fairly high efficiency in indirect and diffuse light from the sun.

2. Inpatient accommodation.

3. More reasonable price compared to the single-crystal samples.

4. Claimed loss of efficiency in 20 years is only 20%.

The disadvantages are the same:

1. In comparison with the efficiency of a single crystal only 12-18%

2. Based on the calculation of the required power, such panels will need more to install.

Polycrystalline solar panels are increasingly gaining popularity. This is due to more affordable price and the development of technologies that increasingly improve the effectiveness of such panels.

Solar panel of amorphous silicon

The technology of production of such solar panels is fundamentally different from the technology of production of the above samples. The essence of the process lies in the following:

In this case, as an essential element is not applicable net nonmetal and its hybrid heated vapors which are condensed on a specially prepared substrate.

This technology dramatically reduces the cost of the final product.

Efficiency of such panels is relatively low and reaches only 12%.

Production technology allows production of solar panels at both the rigid substrate and a flexible substrate. For this reason, amorphous silicon modules are actively used in flexible thin-film solar panels.

Such panels are ideally suited for use in high latitudes (where there is the possibility of using large areas), since their physico-chemical structure provides maximum absorption of the scattered Sveta.

The pros and cons of amorphous silicon

On the positive side are the following:

1. Can produce the thinnest flexible panels

2. High efficiency under diffuse illumination.

3. The possibility of mounting on any curved surface.

4. Is able to operate with significant heating.

5. Limit simple design, which virtually eliminates the possibility of damage to the product.

6. When the working surface contamination performance drops slightly as compared with the samples discussed above.

7. Service life power loss of 20% is 25 years.

The disadvantage is that the equipment necessary for the location of the power required is much larger accommodation space (compared with other types of solar panels).
