Solar Panels: Facing & Settling Challenges
Lives of people become under the threat of energy production decrease, which in its turn, is pushing us towards alternative technologies. Alternative sources of energy are less damaging for the earth and provide a surplus of energy that can be used daily. That is why the popularity of solar panels is growing increasingly.
It is well-known that the conventional energy sources pollute the environment largely and this causes excess pollution in the air and water bodies.
One more well known aspect is that solar energy is renewable and free. Besides it may lead to savings of thousands of dollars annually. This aspect becomes even timelier, taking the downturn into account. Solar panels help with the reduction of electricity consumption by way of receiving thermal energy from the sun and changing it into a form usable by domestic appliances.
As we know now, in the next 100 years we won’t be able to get the needed supply of fossil fuels. And though use of alternative sources is a nice way to get a pretty supply of energy, the problem is that people are getting even more skeptical about the issue and problems that may be caused by pollution. We do not want much, only clean and abundant energy source. But will those solar panels be able to substitute all the household appliances and amenities? Luckily, the answer is positive.
There’s, however, one more important question: whether solar energy would make our future brighter. To this question, still, there’s no definite and single answer. We can hardly say that solar panels alone can change significantly our future for the better, since that is not the only factor.
Solar energy isn’t cheap but one can save money by making and arranging panels at home without employing experts. Besides, there are numerous guides, manuals and books on that point. Solar panels, of course, can be of different price rates as well. But the most important criteria it should be chosen in accordance with are efficiency. Depending on the house you live in you might need a couple of huge panels or vice versa, many small solar panels. Different models, types, producers and brands surely can suggest you something appropriate.
Using solar energy you are not decreasing power of the sun or robbing it. On the contrary, you are taking advantages from its wastes. The only actual problem you may face is the way of harnessing sun rays.
Moreover, many people believe that solar panels exist only in a very weird form. But this does not correspond with reality, since there are nowadays produced special panels of different types and kinds. So that some of them can be easily placed inside the subdivision and would look alright.
No doubt electricity has a significant place in our lives. In many cases people would like to have an independent or additional heating supply source. If you are one of those who are looking for information on hot water solar panels, please check out this site. There you may find lots of details about ground source heating and how to purchase it.
Nowadays the web technologies provide us with a really unique chance to choose what one searches for the best price on the market. Due to this if you are properly armed with the knowledge in your topic you can be sure that you will always find the solution to any bad situation. So, please make sure to get back to this site on a regular basis or – the least time consuming way of doing it – sign up to its RSS feed.

The principle of operation of photovoltaic solar battery
Photovoltaic solar cell consists of several photovoltaic solar modules, which areelectrically and mechanically connected to each other. Photoelectric solar module – a device that constructively combines electrically interconnected photovoltaic solar cells and at the same time it has output terminals for connecting of external customers.
Photoelectric element consists of two thin layers of semiconductor material: one with a small admixture, which gives it the properties of the conductor of negative charges (area n), the second also with a touch, but she turns it into a conductor of positive charges (area p).
When the zone of contact between two semiconductors gets solar radiation, creating an electromotive force that can move the electric current in the external circuit connected to areas n and p.
The main material used for the manufacture of photovoltaic cells is silicon. Silicon doped with phosphorus is a type of n, with boron – a type of p.
The solar modules can generate electricity for 20 years or more. Wear occurs primarily on the impact of the environment, because no thermodynamic processes in the installation does not occur, there are no moving parts. A well-mounted solar array will be reliable, quiet and clean source of energy for many years.
Options for connecting the solar battery
The energy produced by photovoltaic generator is not used with direct connection to the user’s network.
Depending on the objectives of the consumer, the presence / absence and the quality of power supply can provide 2 options to connect photovoltaic solar cells:
Offline
In remote areas where there is no centralized power, solar batteries are usually used for supply of houses. In plants of this type electricity is accumulated in the cells and then used at night or during low insolation.
The system of this type requires that the photovoltaic field was large enough to provide a period of normal insolation as a direct burden of the working of the electric circuit, and battery charging.
The system incorporates:
photovoltaic modules;
charge controller (used to protect the battery from excessive charging photovoltaic generator, as well as from the excessive discharge during use, as both a negative impact on functionality and reduces the life of equipment);
inverter (its task is to convert constant electric energy produced by photovoltaic field, the energy variable type, required for the power user equipment)
system of accumulation (incorporates a number of rechargeable batteries, the capacity of which fully meets the required level of autonomy with regard to power the connected load)
Spare PV systems are used where there is a connection to the central power, but it is unreliable. In the case of network disconnection, or lack of supply voltage, the load is used to cover the photovoltaic installation. Small stand-PV systems are used to power the most important load – lighting, computer and communications equipment. Larger systems can also provide energy and a refrigerator during a power network. The more power needed to power the load responsible, and the longer periods off the network, the more power the photovoltaic system is needed.

Solar Battery – How It Works
The term “solar cell” can be understood in different ways. This is usually referred to as photovoltaic panels, which can convert sunlight into electricity.
Their work bears many similarities to the organization of the transistor. Typically, the material for that product is semiconductor silicon. If there is a need for high-power device, then there is used the battery of crystalline silicon.
In this case we can speak of two types. The first are the battery of single-crystal silicon. Outwardly, this material can be distinguished by the uniform black and gray color of the surface. The second type is represented by the current generation of elements made from cheaper polycrystalline silicon.
Production is made by casting. Material has a look of blue surface with uneven flow. In addition, silicon is complemented by a small amount of arsenic and boron.
The design of the simplest solar power source is as follows: two stacked thin sheet is connected in such a way that will retain the pn-junction. A used sheet contains impurity atoms of boron, the other – the impurity atoms of arsenic. One plate (outer) is characterized by a surplus of electrons, and internal – to insufficient number.
As a result of sunlight is lighting element and the two layers interact as electrodes ordinary batteries – there is emf. Ray “wakes up” the electrons, which are beginning to move from one plate to another. And the production of sunshine is not associated with chemical reactions. That is why such a solar battery can last for very long.
In fact, a limited lifespan does not exist. However, the device battery may differ in some details. For example, thin-layer cell can contain not only silicon, but gallium, arsenide, cadmium telluride, copper, selenium, and more.
Such a model solar cells have not been studied properly. There are some difficulties in the manufacture of these batteries. At the same time, these advanced batteries have certain additional properties. For example, models that use gallium arsenide, and are able to provide greater efficiency and more resistant to temperature shock.
So how do you choose a really working battery? An important prerequisite is the existence of resistance to the cyclic mode. The battery should be painlessly move deeper level, and have low level of self charge.
The important thing is indifference to such processes as a breach of the conditions of charging or discharging. Of course, a good battery should last a long time. You can also draw attention to other characteristics.
For example, how easy it is to maintain this battery, how much space is required.
In addition, the batteries do not emit large amounts of gas and provide oxygen recombination. As a result, water is the electrolyte is not exposed to power and evaporation. This, in turn, means that the consumer does not have to constantly worry about refilling the electrolyte.
The service life of such batteries is no more than 3-5 years. As a consequence, for the life of the solar battery (15-20 years and over) you will need to change the batteries (to add this to the cost of servicing of battery and equipment).
No doubt energy has an important place in our lives. In many cases people want to have an independent or alternative power supply source.

General Information On Solar Batteries
Solar battery minimizes the consumption of diesel fuel and this allows it to work exclusively on solar radiation, depending on local climate and load requirements. Solar energy is a reliable power source for telecommunication devices in remote areas and on mountain tops. Solar panel does not pollute the environment (solution of environmental problems in contrast to diesel power plants), so the battery can be used close to residential sites and in densely populated areas.
The battery cabinet allows the use of diesel generator (gas generator) is always at maximum efficiency. This saves fuel and minimizes the maintenance of diesel generators. Battery also provides uninterrupted power throughout the system, so the battery can be plugged in and working as a backup power supply in places where electricity is available 24 hours a day.
Alternators can run in parallel with an inverter to provide high-energy. No detailed estimates are not required and no complicated procedures of system design are not needed before installation. The alternators will be switched when you connect any additional loads. Specially designed control system contributes to maintaining the maximum service life of the generator and batteries, as well as minimize maintenance requirements.
How it works
The system of autonomous power is an alternative source of energy. It does not require the presence of operators and therefore does not require separate facilities for technical staff. All activities are carried out automatically.
Solar panel converts solar energy into electricity that is stored in the battery. Electricity services are automatically terminated when the battery is fully charged.
Diesel generator (option – gas generators) are also switched on and off automatically. As shown in the block diagram of the system, the voltage can be obtained directly from the battery to apply direct current (telecommunications equipment, DC motors, lighting, etc.) will automatically turn alternators to charge the battery whenever it is necessary ( For example, during cloudy days).
The inverter converts DC battery to AC power and delivers it to the consumer. The diesel generator automatically starts to operate in parallel with the inverter, if a large load is present for a long time.
The energy source is automatically rebuilds its actions to comply with the requirements of the load. It will only work on solar cells, if the demand load corresponds to the solar radiation at the installation. A charged battery can provide power load for approximately 5 days following the cloud. If the load increases, it is the inclusion of diesel generators. As additional equipment can be installed wind turbine (windmill).

Alternative Power Source – Solar Heating Systems
Solar collector with an absorber (eg: dark sheet metal) converts solar energy into heat. Heat from the coolant is circulating in the system of copper tubes from the collector then it is transferred to the water which is heated.
Types of solar collectors
There’s a two most common types of solar collectors:
* A flat solar collector
* Vacuum solar collector
The use of solar collectors for home solar collectors as alternative energy sources, energy conservation is widely spoken about everywhere.
Perhaps the main issue, which relates to solar plants and solar power systems, is their efficiency. The customer, buying not cheap solar panels for their homes are interested in getting maximum performance from their use.
Often, even customers demand from the experts about the exact numbers of heat efficiency and payback period of solar systems. Even in such a convenient and free source of energy is a very important drawback – it is unstable. The weather changes unpredictably, the projections give us only an approximate expectation of data of weather conditions, which give us these same approximate results of calculations. But let’s look at the use of solar panels on the other hand the positive side, despite the fact that the payback period to date is not more than 5 years.
If we compare the parameters of various engineering systems in the home that consumes heat, then the most efficient solar panels work for hot water systems.
Parameters of hot water and its mode of operation can support the work of solar systems at peak performance. Sometimes of course, and the contour of heating the pool, but there are already different scale. Thus, the heating of tap water taken to calculate an average of 10 to 60 ° C, while heating and ventilation systems from 60 to 80 ° C. It is the temperature of incoming water and determines whether the solar system to give her his heat or not.
Another important point is the frequency of use of the system that consumes heat. If only the heating system and is a seasonal heat consumers, but it works in winter and always have tanks heat accumulators not able to be recharged. Hot water system has a periodic use, in the intervals between which the tanks are able to recover its heat charge. In addition, consumption of hot water at home is round.
There is another path, which should be considered-floor heating. The maximum permissible temperature of the coolant in it – 55 ° C, mean temperature of the water in the reverse loop reach 30-40 ° C.
Thus, through the constructive use of the complexity of solar power systems for different contours can be concluded that the most effective is to use solar energy for heating water for hot water systems.
No doubt electricity has an important place in our lives. In many cases people would like to have an independent or additional energy supply source.

Solar Panels – Questions And Answers
Mounting
Installation of solar panels takes several days.
Typically solar panels are installed on roofs of buildings in order to save valuable space. At the same time achieve maximum orientation of solar panels on the south and choosing the angle of inclination close to 45o.
Installing solar panels and determine its size must be implemented in such a way as to be negligible effect giving the shadow of neighboring buildings, trees, power lines, etc.
An important part of the solar system is a supporting frame for solar panels. It provides the correct angle panels, as well as the necessary structural rigidity. The combination of the supporting structure with solar modules is done in order to withstand wind and other adverse environmental impact.
Mounting Options Installation:
* Tilting (on the roof with any slope angle)
* The horizontal (on the flat roof)
* Freestanding (solar panel with a support structure)
* Integrated. United with the network system can be part of the building structure. Moreover, integration into the building can be a great way to improve the architecture of the building and show that the elements of the building structure can also perform the function of generating electricity. For these applications are developed and produced special designs.
It is also possible installation of a hybrid system (wind generator + solar panels).
What is a solar panel (photovoltaic module)?
Solar panel is a device for converting of sunlight into electricity.
How durable is the solar energy system?
For photovoltaic modules (solar panels) manufacturers give 10-12 years to provide power for more than 90%, and 25-30 years to provide power for more than 80%. But, in fact, photovoltaic modules work for 50 years or more. The remaining elements of the system – it all depends on the manufacturer and product.
Where better to place solar energy systems?
Solar panels are usually located on the roof or supporting structure in a fixed position. It should be borne in mind that the sun moves from east to west, has a different angle in the summer and winter. When you install solar panels usually take as a basis angle latitude areas, where the object is.
What payback period of solar power?”
It depends on several factors. First, wired to learn if you have common network or object is not electrified at all. Secondly, the continuing increase in electricity prices payback periods vary. Because you want a detailed energy audit.
How much will it cost solar power system, if the daily consumption of object N kw / h?
Is it possible to install first a solar energy system with a small number of photovoltaic modules, and later build number?
Yes, of course. Addition of photovoltaic are is not a problem. You only need to look at the possibility of a charge controller and inverter.
No doubt electricity has an important place in our lives. In many cases people would like to have an independent or alternative heating supply source.

Talk On Types Of Solar Batteries
What is a monocrystallic solar panel?
Single-crystal silicon photo-elements are most effective and popular among consumers. They are produced by casting high-purity silicon crystals, in which the melt solidifies on contact with the seed crystal. In the process of gradually cooling silicon solidifies in the form of a cylindrical casting of a single crystal of diameter 13 – 20 cm in length with up to 200 cm thus obtained ingot is cut into thick leaves 250 – 300 microns.
Such elements have higher efficiency compared with the elements produced by molds in other ways, efficiency reaches 19%, thanks to the special orientation of the atoms of a single crystal, which contributes to the mobility of electrons.
Silicon permeates the mesh of metal electrodes. Traditionally, single-crystal modules are inserted into the aluminum frame and covered with an impact glass. Color photo of single-crystal elements – dark blue or black.
Sphere of application
Solar panels are reliable, durable and easy to install, since it does not contain moving parts. Solar panels can be used where conventional electricity is not working properly and a large number of sunny days. Examples of solar panels: on rooftops to generate electricity, on street and garden lamps for lighting, charging batteries, providing electricity to equipment on boats, radios, pumps, alarms and so on.
What is a thin-film battery?
Thin-film technology allows making cheaper production costs panel. This circumstance makes film panels more attractive for the construction of larger “farms” on the production of electricity from sunlight, when the sun farmer is limited not so much an area of land as the cost of installing the batteries. Can be installed not only on the roof, but also on the walls of buildings.
Thin-film panels require direct sunlight, working with the scattered radiation, thus the total energy resulting output for the year increased by 10-15% than produce traditional crystalline solar panels. A thin film is much more cost-effective way of energy production and can replay the single crystals in areas with a hazy, cloudy climates or in those industries, which is characteristic of air or dust to high content of other particles.
Sphere of application
Thin-film panel in 95% of cases are used for on-grid “systems that generate electricity directly into the network. These panels need to use high-voltage controllers and inverters, not stick with low-power home systems.
Although the cost of thin-film panels is low, they occupy a much larger area (2.5 times) than the mono-and polycrystalline panels. Because of lower efficiency of thin-film panels effectively used in systems 10 kW or more. To construct a small autonomous or stand-by power supply systems used monocrystallic and polycrystalline panels.
What is polycrystalline battery?
An alternative to single-crystal silicon is polycrystalline silicon. He has a lower cost. The crystals in it are more modular, but have a different shape and orientation. This material, as compared with the dark single crystals is different bright blue. Improving the process of production of elements of this type can now obtain the components, characteristics of which are only slightly inferior to the electrical parameters of single crystal.
Sphere of application
With a solar panel system, you can:
- To highlight and provide electricity to homes and cottages, schools, hospitals, offices, farms, greenhouse complexes, etc;
- Lightning of parks, gardens, yards, roads and streets;
- Ensure telecommunications, medical equipment with power;
- Supply power to the oil and gas pipelines;
- provide electricity supply and water desalination;
