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”.

If you are going to install and use solar power system at home – you are the man of modern views and you are really on the right way. People who have their home solar energy systems both save great amounts of money and lessen environmental pollution. Those who use the solar power at home will hardly ever come back to the conventional electricity. Spend some time learning about the solar power and you will open your mind for knowledge of its use, advantages and price.
The type of energy we are speaking about is the so-called renewable source of energy given to us by the nature in order to grant the mankind with number of its benefits. It is absolutely free for all people so we do not must spend a lot of funds if we wish to enjoy the advantages of solar power. Your household appliances, air conditioning, heat for your water and home air, food cooking using the electric kitchen equipment and others can be provided with the electricity taken from the sun lights by capturing it with the solar panels and converting it to the home direct current electricity. The system works in such a way: if there is the excess amount of energy it will be accumulated in the special batteries that may be used both at night and during the sunny days.
It is absolutely clear that the installation of the system at your home will not be free as in contrast to the natural source of energy called solar power the system for its processing is the “handmade” artificial equipment made with the business purposes. Despite this, you may only imagine how much cost will be saved on your electric bills after the initial money input for the system` obtaining and installation is made. Furthermore, keep in mind that there are special electric companies, which will take the excess energy that you will not need. You will feel the pleasure when see that electricity for your home brings profit. The solar energy using is very useful as for your purse so for the environment. Using the energy brought from the sun, you lessen the CO2 discharge made by heating coal and oil for the conventional electricity.
Are you thinking about the solar power system cost for your home? It depends on several factors. First of all you must think about how much energy do you use and how much energy is being used by whole your family. If you are going to order the services of serious professional in this field it would cost more than 3000 US dollars. But take into consideration that there are numerous web pages regarded to the building of solar power systems in home conditions. Such situation may cost $200 for you. And keep in mind that the more solar panels will be installed on or around your home the more excess energy you will be able to sell to energy companies.
Nowadays, when the financial crisis walks on streets we must think how to save money. This economic situation makes us weak sometimes when speak about possibilities to provide our families with material values. So the thing we may be sure in is that such ways of saving money as using of solar power system is really the right and reliable way to cover our back financially.

Luckily we live in the times when the ruling elites start to understand the value of living in harmony with the nature on this planet. And solar power grants is a real case proof of it. If you want to make a switch to solar energy, please find out more about how solar power grants and how exactly you can use these solar power grants for your living.

An energy crisis broke out, which has put many countries in the face of the energy embargo. Vehicles, factories, central heating system could come to a standstill, and we suddenly realized that our constant need of energy society is built on very shaky grounds.

Today we again have oil (though we must pay for it is much more expensive), but never again in the world would not be such a situation, as it was before.

Growing fears over energy reserves, for our standard of living dominates the world today. Dissipation of energy has become a sin, and the search for new types of energy – the most important task. In magazines and on TV you can now see the unusual building, where solar radiation is used as an energy source. The result may give the impression that the use of solar energy for domestic purposes – something that had never happened. However, the possibility of using solar energy for these purposes has been known for thousands of years ago, but in this century has been opened again. Until very recently, new discoveries in the field of solar energy were published mainly in professional journals and publications of universities, which are available to few. On this site I would like to give information of a general nature and demonstrate a wide range of specialists to provide building heat from solar energy.

Use the oil can, in the end, only for the production of vital raw material and protein. Perhaps a ban on the use of oil for heating is not so far, but it must be caused not by political reasons, but common sense.

We must understand that the additional energy consumption and associated pollution may eventually destroy the entire civilization. Must be “clean” energy. To carry out this can engineers, scientists, architects, builders, politicians. But all people should realize their responsibility and help find a solution to this problem. This site is a direct contribution to the idea of environmental protection through the widespread use of solar energy.

Outside the Earth’s atmosphere flux of 1394 W/m2, or 2 calories/cm2 in minutes. This quantity is called the solar constant. Passing through the atmosphere, a great number of radiation (30-40%) is dissipated and the surface of Earth at sea level on a clear day gets 0.855 kVt/m2-1kVt/m2 direct radiation. Of course, that part (about 50%) of the scattered light in the atmosphere reaches Earth’s surface and in the form of energy.

Duration of solar radiation and its intensity depend on the time of year, weather conditions and, of course, by geographical area. About 25% of the Earth’s surface receives sunlight, ie, the direct solar radiation during the day. In most countries, the duration of direct sunlight and the intensity of radiation measured in tens of days. For technical calculations using the average rates, which are derived from averages for each hour of the day and every month.
These values are determined separately for horizontal and vertical differently oriented surfaces. Using such data, we can obtain the corresponding values of the effect of radiation for each hour of the day.

It is a real gift that we live in the times when the government start to realize the value of living in harmony with the nature on this planet. And solar power grants is a realistic proof of it. If you want to make a switch to solar energy, please read more about how solar power grants and how exactly you can exploit these solar power grants for your living.

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.

Be smart and use the aid of solar power grants to convert your life to enhanced ecological balance with nature. Read about solar power grants, how to make proper use of them and where you can apply for these solar power grants.

Most of people love long trips reaching places far away from home on an RV very much. They go there with their families, friends and pets. Often they reach really far places, wild places far inside the forests, national parks or even deserts. Also many of them have begun to guess the solar panels in such trips are very useful devices in such journeys. May be you will find it not very interesting story, but I could explain how you can improve the quality of the vacations using the solar power. Moreover, you will save the costs.
There is no great secret in the reason. You do save the funds if you use the solar power system. People who use to make such trips usually take with them and accordingly use a lot of different equipment and devices such as television, radio, laptops, play-stations, cookers, mobile phones, music players, irons, kitchen units etc so that they need power outlets for charging in order to feel their like they are home despite they might be thousand kilometers away from their native cities. And all of this equipment they put on their cars and go far away for the long trips. And when they stop for the camping they must find energy somewhere to make all of their equipment units work and work properly, as long as they wish. Despite the fact that some types of the appliances are not able to work from the solar power, most of equipment can. While working the panels produce direct current, which is channeled by the special elements built in the panels into the batteries and transformed by it into the alternating current that is used by such equipment.
So the life goes better when you have solar power production system in the trip. Using it you may enjoy a lot of things during the vacations though you are far away from home. Such things as conditioning, television and laptops and others can be charged with the solar energy. If you go to the sunny lands – the solar power system is one of your best friends in the trip. It does not mean that while travelling in Montana you can switch your solar panel off. It means that the sunnier climate, the more efficient your solar power system. You must also take into consideration that despite some appliances may not work from the sun light, you can be sure that solar panel will bring the great use for you in RV journey. There is the inverter in the polar energy system so that you must not worry about direct current produced by the system, because it will be converted for the use of your equipment. So, a simple decision concerning the changing of your power source for the appliance could do the trip much more interesting, relax and cheap. Moreover, you must know that the installation of the panel is easy and rather cheap.
As for me, I am very glad that bought and installed the solar panel onto my vehicle two years ago. I have calculated recently how much cost could spare during this time and the sum was rather wonderful in sense I had not to spend it. In the nearest future I am going to equip all my dwelling with the solar power system.

Luckily we live in the times when the ruling elites start to realize the value of living in harmony with the nature on this planet. And solar power grants is a real case proof of it. If you want to make a switch to solar energy, please read more about how solar power grants and how exactly you can exploit these solar power grants for your living.

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.

Be smart and use the help of solar power grants to convert your life to better ecological balance with nature. Read about solar power grants, how to make proper use of them and where you can find these solar power grants.

For last several decades the world climate has been changing faster and faster. For last fifty years average temperature of surface in the world has increased more than on 0.7 degrees Celsius. This caused such phenomena as, for instance, decreasing of Arctic Ice` amounts on 2.7% every decade. In the end of 20th century, beginning of 21st, the highest temperatures from very beginning of the history of respective observations were detected. From year to year more and more countries speak about the global warming more and more intensively. The problem of the greenhouse effect became one of the strongest challenges for the humanity.
Governments of the most developed countries have begun to take informational measures in order to make their peoples be more consciousness concerning the environment for the future generation. Many people all over the world try to use alternative sources of power nowadays. They do so because of need to lessen the damage to the environment made by processing and using of classic types of fuel such as oil, coal, plutonium and uranium. One of the most popular ways to make input in decreasing of such damage is using of solar energy at homes and businesses. They use solar power generators that give them the possibility of get electricity from the sun energy without burning of usual fuels (that leads to formation of greenhouse gases around the Earth, which do not give the way for the heat to go out to space).
Internet contains numerous web pages related to the building of a solar power generator. Generator gives people the possibility to use generated electricity from the solar power. The energy is produced from the great heat of the sun. Special panels take the heat and transport it to the generator. The generator makes electricity from heat of the sun. And after all there is no damage to the environment. People may take this solar power as much as long the sun light touches the panels. Moreover, the energy source in this case is inexhaustible. The only thing people needs here is the heat of the sun.
If peak about the fossil fuels, the way of taking the energy from it is rather complicated and often is not defensible (despite the fact that it could proportionally give more energy than the sun lights, taking into consideration the modern level of technical development). Fossil fuels have to be found, taken out from behind the ground and processed before people can use it. All you need to get energy from the sun heat is its light on the panels. Furthermore, mines, where fossil fuels usually are taken out, often run out and you must look and process another one. One of the negative sides of such energy sources is that there are cases when while processing them people often die. It relates to coal mines in most cases.
If you are really consciousness, and if you really care about the future of your children think about the pollution of the air. All you have to do is to build the solar power generator. If you do not use too much energy at home, or if you build enough powerful generator, or both this and that, you may be guaranteed that electricity from the sun light will be enough for you.

Luckily we live in the times when the government start to realize the value of living in harmony with the nature on this planet. And solar power grants is a realistic proof of it. If you want to switch to solar energy, please read more about how solar power grants and how exactly you can use these solar power grants for your living.
