The Batteries on the solar cells are beginning to gain popularity among the population. They are mounted on rooftops, vehicles. Some of them are adapted even for electronics, a wrist watch. At the moment they have become a viable alternative of electric power or act as a Supplement.
The Solar modules are the most important element in the photovoltaic system. They are panel, which includes solar cells made from silicon.
To generate electricity all these components are assembled into blocks, which are then upholstered laminated film – this is necessary for sealing. Then all fits in the frame. The device is simple enough, but to collect at home will be problematic. Alone is not possible to collect a photoelectric element, which cannot be said about the panel.
The Batteries on the solar cells are divided into several types. Among them there are:
Solar Panels consist of photovoltaic cells, which in the process convert the energy from the sun into electricity.

A number of advantages can be attributed to the following:
Despite all the advantages, the work can meet and negative points:
These panels are widely used not only in everyday life, in the process of life, but also in industry and in the production of:
All the energy that is produced during daylight is stored in batteries, after which the devices can operate even in the dark.
Solar cells operate on the same principle as in the time of the first development. This principle is familiar to everyone, as it studied in the school curriculum, conducting physical experiments. Transistor, which was missing the top cover, contributed to the penetration of light on the transitions of p and n.
Once connected to a voltmeter, you can see that at the moment of impactsunlight was allocated a small amount of energy. Previously, scientists conducted experiments at work, have increased the area of the transitions. As a result, there appeared solar panels.
The Design of the solar system elements contains:
You Should know that the energy from the sun is impossible to get throughout the day. The battery is not able to function at night. In winter, daylight is reduced. At such moments, the main unit requires the addition of energy storage.
In most cases the use of an electric battery. It is connected to the panel and stores the power generated, with the result that the work is carried out in the evening.
The Level of efficiency completely depends on the material used. For example, when using monocrystalline silicon, it is equal to nearly 20 %, polycrystalline silicon reduces this figure by 10 %. The level of efficiency can influence the smoothness of the surface, temperature of air, the location of the batteries to the sun.
To date, the use of environmentally friendly materials is most important. Electricity that turns on the power – nuclear, water, thermal, constantly going up. This is due to the expensive production. In that moment, when it is used solar battery, people can rightfully consider themselves independent, even from the state, which provides electricity for use at an inflated price.
Once you spend a certain amount of money, then you can completely forget about the utility bill on the counter utilities. At a time when installed these panels, the transfer of the house. This includes not only light, but also heating, plumbing – hot water.
Radiation of sunlight – it is a great source to produce electricity. And most importantly – this source is free, clean and inexhaustible.
Most solar cells are manufactured using polycrystalline silicon and monocrystalline silicon. The production process requires a lot of time, effort and funds.
The main stages of production on the basis of monocrystalline silicon include:
Solar cells are interconnected in parallel, sequentially or in parallel series. The choice depends entirely on what level of stress is necessary to obtain in the process.
The production Process of the module tothe basis of polycrystalline silicon in the same manner as when the single-crystal silicon. The difference is present only in cultivation. There are several methods, but at the moment, the popularity of only one – Siemens-process. The whole essence of the method lies in the fact that initially restores the precipitated silane and free silicon. This is done in collaboration with the special mixture, which contains the elements of hydrogen and silane using a temperature ranging from 600 to 1350 degrees Celsius.
In this way the process of production of solar panels.
Many people tend to assume that batteries with solar cells with their hands going is difficult, even almost impossible. In fact, things are different. Make an effort going to need a lot, but the process is not difficult as it seems initially. The main difficulty which can be encountered in the process – it is collecting solar cell with their hands. If you manage to create such a mechanism alone, it will be possible to think not only about the rejection of payment for utilities, but also for the realization of their own business. At the moment, solar panels are very relevant to the sale of energy playing them. The most important thing – payment is made in one of the most stable currencies – the Euro. Is the production of solar cells is not worth attention?
In order to work with fotoacademie need to have skills and experience in this field. The first thing that comes to soldering and careful attention to all the elements. To work you need to have good soldering tool that is suitable for fine work. To create mono - and polycrystals will not work. You can use the finished workpiece.
The First step is the selection of the necessary foliaceus. For battery life you can use silicon to poly - and monoacetate. The most important thing – to take into account the level of performance and nuance at work. For example, in monotoniko efficiency is higher, but in poliyacheykami lost considerable energy in cloudy time.
All cells are divided into classes. All of them there are four. Class a has the better quality with no defects. This class is used in the solid and large organizations, companies. Performance working high, but the cost is appropriate.
When the production of the batteries themselves, you can choose the class B. the Efficiency is lower than that of previous items, the cost is significantly different. Some organizations use this class in the manufacture of batteries to implement, which explains the low efficiency.
Some people buy all they need over the Internet shops. If you go to a specialty store, you can buy all the components at once. Then you won't have to wait for delivery.
For collecting the solar cell will not be enough only cells since they need some way to connect with each other on the scheme. This will require the use of guides and additional materials. That's why some manufacturers offer to buy the box set that already has all the material needed in the work.
In such a set may include up to 72 elements, conductors, bus, and diodes for the circuit and a pencil, which includes a special acid for soldering.
Some sets may contain the finished patacake to which the soldered conductors. To collect just enough to collect all according to the diagram and connect. This is the optimal alternative when solar cells to build solar panels are connected manually. The material is very small and fragile, which causes a number of problems in the process.
In that case, if all the material – elements and conductors were purchased separately, the entire soldering process of solar cells will look as follows:
Such work is very laborious, not the fact that get everything done right the first time, you may need to repeat the whole process several times. If you examine the rules we can understand that the plated conductors made of silver calculated on three cycles of soldering. There are cases when the conductors are pre-applied solder, the manufacturer warns immediately. But it is best to apply it additionally. In the process, it is forbidden to put the solar batteries on top of each other, as you can damage them due to too much pressure.
The Final step is to seal all elements. But before to start it is necessary to pay attention on the reliability of adhesions. To do this, use a multimeter. The test can be carried out after completion of all work, or during the whole process, after soldering each individual element.
Forthe sealing process is often used silicone sealant. First, he applied to the joints of the elements, and then the whole panel surface. For such work you can use a brush to apply it you need only to joints as it is possible to move the cell from place. Once everything has dried, you can close the cover.
At the moment you can see the battery with two types of solar cells: monocrystalline, polycrystalline.
Each type has advantages and disadvantages in the work, you should be aware of before making a purchase.
Market Opportunities and production does not stand still, regularly there are novelties in the process of manufacture of which use different technologies. Before you make a choice, it is recommended to pay attention to the characteristics of solar cells: the efficiency for a battery that can store energy during daylight hours and to develop it in the dark. All of this information beforehand provides the manufacturer, they can be found in a specialty store. It's best to find online information or discuss with the experts which option is best.
