Renewable energy sources are important not only in terms of diversification of the electricity technological base. The world community is seriously concerned about global climate change today.

As it was demonstrated by research conducted by Exxon Mobile, the world’s energy needs are increasing by 1.3% annually and will increase on 40% in comparison to indicators of 2005 by 2030. 40% of this rising will be made by the increasing of energy generating sector. Consequently, emissions of carbon dioxide (CO2), related to the energy sector, will also increase.

One of the key factors that may reduce greenhouse gas emissions is the use of renewable energy: solar, wind, biomass, hydro, tidal and geothermal energy. The development of these technologies is supported at the state level in most developed countries. In particular, in March 2007, the Council of Europe has set a goal to bring the use of renewable sources up to 20% of the total energy consumption of the EU till the year 2020. The development of solar photovoltaic is connected with large-scale renewable energy support programs, implemented in highly developed countries of Europe, in the USA and Japan.

An important advantage of solar photovoltaic systems is the lack of carbon dioxide in the process of systems work. Although indirect emissions are present at other stages of the life cycle of the system, photovoltaic technologies generate far less emissions per GWh of energy generated throughout the life cycle than the technologies that use traditional fuels. At least 89% of emissions related to energy production, could be prevented by replacing the traditional sources of energy with PV. In addition, photovoltaic does not cause any other forms of pollution (such as exhaust fumes or noise). The reduction in annual carbon emissions through the use of solar photovoltaic systems may reach 1,6 billion tons by 2030, and the net loss will probably reach 9 billion tons.

Furthermore, in comparison to other types of electricity production from renewable sources, solar photovoltaic has the greatest potential for long-term growth. It is estimated that the sunlight striking the Earth every minute is sufficient to meet current global demand for energy during the whole year.

According to the European Photovoltaic Association (EPIA) forecasts solar panels will produce up to 2,7 TW of electricity, meeting from 9 to 14 percents of the world needs in 2030. The annual PV market will reach 455 billion EURO.

What can we say about the industry today? Photovoltaic market overcame the rapid growth in 2008. It was caused mainly due to the further development of existing markets (Germany, USA, Japan), an impressive amount of projects in Spain, as well as the new markets emergence in Europe and South Korea.

Volume of the world’s PV market reached 5.5 GW of annual plant systems in 2008. It increased on 129% comparing with the 2007 indicator. Almost half of new plants (2.5 GW) were installed in Spain. Germany has got the second place on this scale (1.5 GVt).

One of the most efficient ways of solar energy using is direct conversion of it into electricity in photocells. Solar cells are light-sensitive plates of a semiconductor material: selenium, silicon, gallium arsenide, silicon diselenide etc. Photovoltaic is being produced when the particles of light (photons) absorbed by the semiconductor, create an electrical current. Solar panels can be of different capacities – from portable units of a few watts to huge stations, covering millions of square meters of space.

In order not to depend on daily and seasonal solar cycle and atmospheric conditions, there are technical methods of energy storage such as: accumulation of electrochemical by batteries, mechanical accumulation (using rotating flywheels) and those in the form of hydrogen. It is also possible combine PV with other energy sources. For example, a combination with the wind installations is most likely, as well as with the systems on fossil fuels.

Photovoltaic systems (solar panels) require minimal maintenance. They do not use any water, so they are well suited for remote and desert areas. This method of solar energy converting is a durable and environmentally friendly. It also can be used to improve the ecological situation in the places of use. In the future it will regulate the environmental conditions over large areas.

Basic requirements for solar batteries include: lighting, consumer electronics work (radio, TV, fridge), pumps for lifting water in remote rural areas, environmentally friendly energy supply zones of mass recreation and treatment; radio- and telecommunications systems supplying, supplying of beacons and buoys. Solar energy using systems can be both environmentally friendly and also have a positive impact on other spheres of life. For example, using of solar panels in the hot desert areas as the sun shade providers makes favourable conditions for growing melons and citrus fruits underneath, which should use not too intense solar radiation. Another example is solar panels or solar collectors using as building elements as facades facing panels ( “solar houses”).

There is a constant increase in solar collectors’ production in many countries. At present time, their global installed capacity is estimated at 10 GW. The total area of solar collectors in the world according to incomplete data exceeded 21 million m2. Annual production of solar collectors is more than 1,7 million m2. Lead countries: Japan – 7 million m2, U.S. – 4 million m2, Israel – 2,8 million m2, Greece – 2,0 million m2.

Photoelectric conversion of solar energy is one of the fastest growing worldwide trend of renewable energy using. At present time, the total capacity of installed solar PV systems is over 938 MW. Annual growth rates have been reaching 30% over the past 5 years. Leading countries are: Japan – 80 MW, USA – 60 MW, Germany – 50 MW.

Using of photovoltaic solar cells is limited by their higher cost of generated electricity, comparing to the energy obtained by using of traditional energy sources.

In today’s realities of growing global energy issues the question of transition to alternative energy sources becomes increasingly relevant. Orientation, which takes place in the direction of oil, gas and nuclear energy could lead certain countries to a serious energy dependence on the world’s largest suppliers to these sectors of energy and now threatens the economic security of many countries. It is clear that all the energy problems will not be solved by alternative sources of energy in the coming years. But focusing on them gives a real opportunity to strengthen position of a state in the future, to increase state’s energy security.

For instance, the following statistics confirms the world trend emphasis shifting in the way of alternative energy. In 2007, investments in such energy made more than 100 billion U.S. dollars all over the world. And according to the experts, the global volume of electricity generated by renewable sources reached the level of 240 GWh. These figures correspond to 50 percentage growth of alternative energy in comparison with the data in 2004. Alternative energy sources make from 4 to 8 percent of total world energy market under the various estimates today.

International Energy Agency believes that the world energy obtained from sun, wind, water, earth’s warm, as well as biomass will increase twice in comparison to 2009 till 2030. It will make 16 percent of the total world energy production. The European Union of industry of renewable energy estimates the situation even more optimistic. From its point of view, the share of alternative energy will rise to 35 percent by 2030. The European Commission believes that one fifth of the energy will be produced from environmentally friendly sources in 2020 in Europe. In Germany, as one of the most focused on alternative sources of energy countries, the share of renewable energy may reach 40 percent and about 67 percent in the production of electricity, – according to the data of federal union of renewable energy.

Nowadays, solar energy is one of the most visible among alternative sources of energy. In addition, the energy sector is one of the most rapidly growing, encouraging professionals to give him special attention. Experts estimate that the global solar cell market is growing by more than 30 percent annually. According to information released by the European Association of photovoltaic industry in the European Union, under favorable conditions, volume of electricity produced by converting of solar energy, may exceed the certain indicator of 2006 by more than three times till 2010.

What is the popularity of solar energy due to? Firstly, the solar energy is available in any place of our planet having different flux density radiation not more than twice. Therefore, it is attractive to all countries, responding to their interests in terms of energy independence. Secondly, the solar energy is a clean source that allows to increase using of it without increasing the negative impact on the environment. In addition, solar energy – is approximately inexhaustible energy source that will be available to humanity in millions of years.

The world will have to end dependence on fossil fuels and reduce emissions of greenhouse gases dramatically in the nearest few decades. In case of success, five technologies will change the energy picture of the world radically.

Scientists suggested producing solar energy in space, in the place the sun always shines, more than three decades ago. If you put giant solar collectors onto orbit around the Earth, they will be able to supply electricity to any place in the world non-stop. The idea is that sunlight is reflected from the giant orbital mirrors, being accumulated in the numerous photovoltaic cells. Then, light has to be converted into electricity, and then – in the microwave rays that are directed toward the Earth. Antennas placed on the Earth’s surface capture the microwave energy and convert it back into electricity.

Technology makes you think about science fiction but is actually very simple. The solar collectors in orbit located approximately 30 000 kilometres from the Earth emit energy in the form of safe microwave rays. An earth mile diameter station host of microwave emanation would make about 1 000 megawatts of energy, which will be enough to power more than one million households.

The cost of solar panels sending into space is the biggest challenge, as it is necessary to design a system of very light weight, so it took only a few launches.

Vvehicles’` transfer to the electricity could reduce oil consumption and clean the air. But it can be real only if the energy used by electric cars is obtained from the atom, wind or other clean sources. The second question concerns to the battery capacity.

In the lithium-oxygen batteries, oxygen goes through the carbon cathode and having united with lithium ions from a lithium metal anode using the electrolyte produces an electrical charge. Such catalyst as manganese oxide helps the reactions to be conducted.
Lithium-ion batteries, commonly used in laptops, are already being used in hybrids and next-generation electric vehicles. They are more powerful than other batteries for cars, but are very expensive.
.
As an alternative a lithium-oxygen battery may be. Its performance is ten times more than the performance of lithium-ion batteries and is comparable with the performance of gasoline running engines.

The wind and the sun are inexhaustible sources of energy, but the energy generated by them must be spent immediately on the spot yet. Moreover, these energy sources are unstable The question is how to accumulate and store the energy produced by them.

Rechargeable batteries can save electricity from the windmill or solar panels, and deliver it when the sun does not shine or the wind does not blow. A promising idea is the use of lithium-ion technology for energy storage. Currently, researchers are exploring new materials to improve performance and capacity of batteries and reduce their price.

Scientists also consider the experimental technologies that will limit carbon dioxide emissions from coal-fired power plants by 90% while limiting the growth of expenditures.

Projects of alternative energy sources have been implemented in many western countries within the last decade. It regards to wind, solar, tidal and so on. This is due to increasing of prices for oil and gas, the depletion of their readily available resources, as well as damage caused to the environment with the use of fossil energy sources. The diversification of energy in their countries becomes the main thesis of many western governments.
According to The Guardian, scientists from the Institute of Energy of the European Commission with support of the EU have developed a unique project of creating of the huge solar power station in the Sahara desert worth almost 36 billion pounds sterling. Its task will be to supply European Union countries with solar electricity all year round. This will be a rise of electricity that one from the “wind farms” in Denmark and Britain, as well as from geothermal sources in Iceland and Italy. The project is being supported by British Prime Minister Gordon Brown and President of France Nicolas Sarkozy.
Chinese have also developed their energy alternative. The share of renewable and clean sources in China should reach 15-20% by 2030. Alternative energy will take almost a priority position, satisfying 43% of all China’s energy requirements till 2050.

In general, the world has already been shifting to renewable energy and it seems only Russia has got little knowledge about this transit. Russia have not thought seriously about alternative and renewable sources yet. However, recently the Act regarding the renewable sources of electricity has been amended. But there are no really working programs yet. The speed of socially significant and potentially dangerous nuclear projects adoption with the construction of dozens of nuclear power plants across the Russian Federation concerns very much many scientists and experts.

At the same time, in the early 90-ies one Nobel laureate who is now a vice president of Academicians Department Jaures Alferov said that if there at least 15% of those funds that were invested in nuclear energy has been spent on the development of alternative energy in Russia, in general the plants now would not be needed. And recently, he reiterated his view on the St. Petersburg International Forum “Science and Society” with the participation of world stars, including eight Nobel laureates. “Energy of the future will be based on large-scale use of solar energy”, and “bet on solar photovoltaic should be seen as a win-win and the only possible choice for mankind”, – said the scientist. According to him, “the volume of solar photovoltaic systems production is growing at the present time, this number equals about 30% annually” and “in 20-years the market dynamics will increase 140 times”.

It turns out that if Russia actually fell out of the global transition to alternative sources, the “Energy Future” will be formed without it. Many serious scientists, taking into consideration all the features, problems and prospects of modern energy market, consider this approach short-sighted and even threatening national interests and its security.

United States of America, having huge amount of solar resources, were in the forefront of research in the field of solar energy and kept the lead from the beginning of the century. Although the government of the United States is still focused on the priority of nuclear energy, yet it is directly or indirectly provides significant research in the field of solar energy. Even the Atomic Energy Commission (AEC) has its own laboratories, which study the sun.

The biggest aid (from the state) is conducted through NASA (National Aeronautics and Space Administration), NSF (National Science Foundation), NED (Office of Housing and Urban Development). In September 1974 the law was ratified, which provides special budget for the establishment of solar heating systems ( “Law on the use of solar energy for space heating and cooking”).

Approximately 80 large companies, including such giants as General Electric, Westinghouse, Motorola, DuPont, Honey-well, Corning, PA PG Industry and Arthur D. Little, Inc. together explored opportunities in the market with the help of special institutions in 70s. The conclusion from their studies said that the industry of solar energy for household purposes (space heating, hot water, cooking) would produce 1,3 billion dollars in profit by 1985. The time confirmed their research was correct.
According to forecasts, the sun that is hardly used now as an energy source, will meet about a quarter of the country’s energy needs by 2020 in the USA and can help reduce oil imports, especially taking into consideration that by that time oil and natural gas extraction in the United States will be negligible.
To increase the role of solar energy efforts are needed. First of all, and it promises the greatest effect, you need to make direct use of solar energy to heating and cooling of buildings both in the private sphere and in industry and agriculture, and secondly, you need to be able to convert solar energy into electricity, that will open an inexhaustible source of electricity; in the long term, this goal has the highest priority, and thirdly, solar energy should be used for the extraction of gas from the fertilizer, wood and other household waste. Although, of course, the technology, known as biological energy, is not in a position to make a significant contribution to the conservation of energy to the next century.
Americans try to keep up: a well-known environmentalist, former Vice-President Nobel Peace Prize winner Al Gore urged the US government to transform all the electricity sources onto the renewable sources, to make it completely independent from the traditional hydrocarbon resources in the nearest 10 years. According to the American press, Gore for himself has solved this problem long time ago: he installed solar panels at his home, energy-saving fluorescent lamps and other environmental “curiosities”.
Appeals of the former Vice President fit into the state program of the U.S. development of solar energy. By analogy with the European it is called the “Million Solar Roofs”.

When light falls on any surface, its temperature rises comparing with the surrounding air. This temperature increase is the result of accumulation of heat on the surface due to energy absorption of solar radiation. If a heated surface we’ll have capacity, which will circulate the water, the water will be heated.

Time raising the temperature to the desired level depends on the amount of calories, which receives water from the sun, as well as from the device absorbing elements (solar collectors) and batteries (tank, tank).

Dr. SGAbbott, a pioneer in the study of solar energy, in his book “How to use the heat from the Sun” describes the primitive, but nonetheless a convenient generator of hot water this way: “I bought a 6 m long, black garden hose, wound 4m around a wooden frame and raised the design of the stairs on the south side of the roof of my house. Others 1,5 m I tied to the faucet in the yard and to the faucet in the bathroom. With this simple device on a sunny day we had a very warm 22 liters of water every half hour.

Of course, installation, commercially profitable, now is not so simple. However, they are arranged but the same principle, albeit with much greater efficiency.

Modern solar hot water generator consists of two main parts: a solar collector and the reservoir with warm water. The surface of the collector can heat water from 50 ° C to 80 ° C. In the vacuum collectors with ideal surfaces, the temperature reaches 300-350 ° C. The use of parabolic radiation concentrators allows to reach even higher temperatures. Sun-heated water from the reservoir (55-56 ° C) enters the heat exchanger solar tank (tank), which is heated to the desired use of water (150 – 500 liters). This heating may be different depending on the duration and intensity of sunlight. The circulation of heated water could be due to thermosyphon principle or with a pump, which is controlled by a thermostat, set at the highest reservoir.

Tanks (tanks) may be made of metal or plastic and must be thermally insulated. For industrial purposes, which require a lot of water, use of mass production of tanks with a capacity of several thousand liters. These tanks are suitable for hospitals, barracks, bath houses, campgrounds, hotels, boarding schools, etc.

Collectors may be combined in series, and the daily rate sun-warmed water, thus, will be increased.

8 North Africa and the Middle East are set to give a day 50-100 thousand liters of hot water. Large installation of this kind exist in Europe. For example, the French firm “Sofe has built a highly productive installation at the hotel with 35 rooms and camping. In Bern, Switzerland, operating facility, which produces 9 thousand liters of hot water with the help of 40 m2 surface of the reservoir.

In some Japanese plants solar collectors and tanks, batteries constitute a single system. To ensure that the natural thermo circulation, tanks must be at least 600 mm higher than the upper reservoir, if it is not possible to use a circulating pump. Contact with the house is reinforced by thin copper tubes with a diameter of 30 mm, the use of which avoids the heat. For cloudy days provides electric heating element with capacity 0,5 – 2 kWh, an adjustable thermostat. Tanks and piping work under pressure of about 6 atm., And the test pressure, in many cases equal to 10.12 atm.

The humanity has known about electricity for a long time. Ben Franklin, for example, experimented with lightings in 1750th. At the very beginning of the 19th century Alessandro Volta invented the device called electric battery, and till the beginning of the 20th century people from different sides of the world could use electricity transmitted for thousands of kilometres by power lines, electricity was used by people in many spheres of life.
Nowadays electric power is generated by huge turbines. In their work, rules described by the scholar Michael Faraday in the first half of 19th century are used. In order to make turbines work, manufacturers usually use such energy sources as coal, oil and plutonium. To take energy these materials are being processed and burnt.
While, for instance, the coal is being burnt, many different kinds of pollutants, for example, carbon dioxide enters the atmosphere that make great terrible input into the global warming. Also, this mineral wealth is the main source of pollutants in our country. Modern world economic system followers can not refuse from the statement that the plants we have now all over the world will work for next many decades and man depends on electricity too much, without electricity we would make step back to the 18th century.
Alternative sources of energy, such as solar power, wind, water and others become more and more popular in the modern world. Solar power has been taking its positions as the most efficient source of power for households during last decades. It is really not too difficult and not too expensive to install solar power system at home. Furthermore, it is not dangerous for the environment to use such systems. The main thing here is double effect. Firstly, using solar power people make input in decreasing of the strain on the public power system. Secondly, when you use the solar power, you can fill better because of the knowing that you make something really useful for the life of next generations including your children and grandchildren.
You also help your family budget. Think: power bills become cheaper and cheaper, and the sum you economize rises from month to month. And if you will calculate the economized funds in the end of life, let us say in 50 years, the sum will be huge.
Moreover, solar power has many other different advantages you couldn’t even guess. For instance, you can use such energy source for the cooking of food. Solar cookers are new nowadays, but it is proven that they do their work not worse than the classic ones. Moreover, they could show you many new options caused by using the solar power.
The level of modern science development makes the dreams come true. Speaking about solar power, nowadays families with average income have the possibility to make their homes really be empowered by the sun lights. Despite some solar systems are rather expensive even now, for example, solar heating systems, it is clear that they will become cheaper and more accessible in the visible future.

In this article we will discuss some themes related to different types of constructions used to produce solar power. We will begin from the grid-tied systems.
A utility-interactive solar power system makes electricity, which is put directly to the grid. The word grid-tied means, that the system is tied, verbatim, to the grid. This system will accumulate the energy even when you are absent, when you and you are on vacation with your friends during the holidays. You just may use the energy after you come back home. That is why you will reduce your electricity bills` costs or even forget about them.
Known as solar modules (photovoltaic) panels, they give the beginning for very interesting process of transforming of solar energy into solar power. The word photovoltaic sounds in such a way because of physics rule, which says how the solar energy may be converted into electricity. Briefly, there are many silicon cells in each such panel, every cell gives the reaction with photons (units of lights), which came from the sun. Than direct current electricity is produced.
The construction of the panel also contains so-called mounting racks, which are used to orient PV panels properly. For instance, the panel may face the west, while the most effective side is north. There are three types of mounts, which are available: the most popular in cities rooftop, and less used ground and poles, which are set in concrete. There is also a great amount of additional equipment that is being used with the panels. But it depends on the certain type of the panel.
There is also a DC disconnect, which is used when safe disconnect of the flow of electricity from the PV panels is needed. It may happened in case of overload.
Such detail as inverter makes the raw DC power, which is produced by the solar panels, be converted to usable AC ( that means alternating current) power that may than be used in exploitation of the household equipment, lighting and other electric devices. That is because all of them run off alternating current electricity.
Such device as the AC Breaker Panel/Inverter AC Disconnect is located in the place where the dwelling wiring touches the power supply. It consists of special elements that can be used both for protecting from fires and for usual purposes.
Speaking briefly, all three types of panels are working similar. It is important to know some things when you decide to by the PV panels. You must buy the right panel depending on how much power your home needs, how much room and land you have to understand where it can be mounted.
You also can find that some manufacturers and sites saying that panel A is much more better because it is more effective at low light. It may be true, but listen: one panel may be more effective than the other under the same sun light with the difference of 1 percent. But in the same time this more efficient panel may take 15 percent more room space. So take it into consideration. If you have enough space you may take it, but in another case think before you buy the panel.
