PostHeaderIcon Solar Collectors And Tanks

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 help of solar power grants to convert your life to enhanced ecological balance with nature. Read about solar power grants, how to use them and where you can get these solar power grants.

PostHeaderIcon Types Of Constructions Used To Produce Solar Power

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.
