Solar Water Heaters: Saving Your Money Using A Solar Water Heater At Home

February 8th, 2010

Solar water heaters or, as they are likewise named, solar domestic hot water devices, can easily be a cost effective way to produce hot water in your house. They have the ability to be made use of with virtually any climate, plus the fuel that they use – sunshine – is 100% free.

The prospective benefits might possibly break down your resistance to the idea of making the investment in a solar water heating system that’s a component of building an environmentally friendly residence, along with other more traditional means of reducing energy costs.

What They are Made Of

Sunshine powered water heating systems consist of storage tanks coupled with solar collectors. There are a couple sorts of these heating devices: active – which include circulating controls and pumps – as well as passive heating systems, that do not.

Passive heating devices are generally less costly than active systems, though they’re commonly not as economical. Still, passive systems may well end up being more reliable and may well last longer. Regarding active devices, you ought to talk over the upkeep requirements together with your system supplier and check with the system’s owner’s manual.

Heading Down the Tank

Nearly all water heaters which operate on sun power need an insulated storage tank. Solar storage tanks include an extra electric outlet and inlet connected to and from the collector. In 2-tank designs, the solar heat tank warms up water just before it goes in the standard water heater. In single-tank designs, the backup heater is joined with the solar storage in one tank.

Electrical Power While the Sun Isn’t Available

Solar water heating systems nearly always demand a backup device for cloudy days and periods of greater need. Traditional storage water heaters normally provide backup and may possibly already be a component of the solar heating package.

A backup system might also be an element of the solar collector, like rooftop tanks with thermosyphon models. Since an integral-collector storage system already keeps hot water as well as collecting solar heat, it might possibly be tied in with a backup water heater.

Up Front Issues to Consider

Prior to when you purchase and install a solar driven water heating system, you need to consider the immediate and ongoing expenses of solar energy devices, examine your site’s solar resource, establish the correct system measurements and power efficiency, and then read your local requirements and polices.

The correct assembly ?s dependent upon your solar resources, climate, community building code standards along with safety concerns. It is advisable to get a qualified, solar thermal systems service provider install your system.

Normal upkeep on simple devices can end up being as sporadic as each 3–5 years, and if at all possible completed by a solar service provider. Systems having electrical components normally require a replacement part after a decade.

The Payback

While you can find limited complications with existing solar water systems, the technological innovation is quickly becoming even better. For a customer, these systems are a wise commitment because they will pay for themselves in a brief amount of time, therefore trimming back on your power bills.

Moreover, several governments provide rebates to consumers who invest in environmentally friendly solar energy systems. While saving money with solar power and other measures to reduce energy costs, you are able to additionally be environmentally friendly simply by decreasing your dependence on fossil fuels.

What Are The Sources Of Renewable Energy

January 24th, 2010

For so many years people have been using fossil fuels such as gas, coal and oil to generate energy, except now sources of fossil fuels are depleting – plus they create pollution when they are burned too. People are now beginning to realize that we need to find types of sources include solar, wind and marine energy.

One of the most widely used and well-known sources of renewable energy is solar power. Everyday the sun produces a huge amount of energy and that sunlight can be utilized to convert into electricity through different technologies. It can be collected by solar collectors. These are the heat-absorbing panels that you see installed on many rooftops. The way these solar collectors work is that they harness solar energy and turn it to heat energy. Water is heated by the heat energy and then stored in water tanks. Solar collectors are used to heat the water in your house as well as to heat swimming pool. Both makes use of the same technologies.

Wind power is another major sources of renewable energy. The energy produced by the wind comes indirectly from the sun, that is the sun heats the surface of the atmosphere and causes the wind to blow. Wind power is preferable to the use of fossil fuels as it doesn’t produce any greenhouse gases and it is an abundant resource. The concept of using wind energy is not new. Wind power was originally being used to generate electricity by the ancient Egyptians and by the beginning of the 20th century wind power was used extensively in Europe, in particular Denmark. However it was the introduction of cheap oil and gas that ruined the wind power industry. It is only at this time that people are getting interested in wind power once again because of the issues with pollution and green house gas emissions.

Scientists are looking at developing technologies that extract energy/power from the waves and the tides. Marine energy is thus another of the main sources of renewable energy. As an energy source it is sustainable and has very little impact on the environment. Using water for energy is quite a new idea and there are no commercial wave energy equipment on the market at the moment. But, there is some technology that is being applied and experimented. One such technology that is producing power on the Scottish island of Islay is a device known as LIMPET. More and more technologies are being developed all the time. Watch out for any new innovations in marine energy technology next time you pick up the newspaper or an environmental magazine.

Geothermal energy is the last in the sources of renewable energy that is going to be mentioned in this article. The simplest way to make full use of geothermal energy is by salt water and steam that is trapped in the many layers of rock underneath the earth’s core. Natural hot springs are the most popularized form of geothermal energy that has been used in the past centuries. But, geothermal heat pumps are the new “it“ energy product. Although geothermal energy is sustainable, it is not readily available. This is due to the fact that not everybody stays by a geothermal reservoir and that often the technology is far too expensive. But it is still good to have this as an option.

Learn How You Can Create A Free Energy Home

January 20th, 2010

All of us are affected by the global recession, and with the price of fossil fuels sky rocketing, many people are searching for free energy home. This is where renewable energy comes in. Renewable energy is an energy source such as solar, wind, water, and geothermal power that continues to replenish itself. Not only are these energy sources free (the only cost required is in the technology to set it up), but also there are no environmental pollutants created either.

The sun is probably the most important source of free energy and can be utilized by either solar thermal collectors or photovoltaic technology.

Solar thermal collectors work by harnessing solar energy i.e. the sun’s rays, and turning them into heat energy. Water then circulates through the coils in the thermal collectors and is then stored in tanks – much like your traditional hot water system, without the use of expensive electricity. There are a number of various solar collectors available in the market, it actually depends on your objective and what you wish to achieve out of the free energy home system. This includes unglazed panels and flat plate water collectors.

People install unglazed panels usually for swimming pool heating. This is because it is not so crucial to keep the heat in and the cold air out – it is only necessary to increase the temperature by a few degrees above the air temperature. However, flat plate water collectors are different. They are typically used for water heating in your home and because of this, it is crucial that you have either single or double-glazing on the panel. There are other solar thermal collectors that are not so common, which do not require to be discussed in detail here like flat plate air collectors and evacuated tube collectors. There are quite a number books and periodicals that you can read that will give you advice and instructions on how to make solar panels such as these.

The other most familiar use of solar energy for free energy home is photovoltaic cells, just like those used in calculators. Light is converted into electricity in a semiconductor much like a computer chip. Technology is always improving and the market is growing quickly. These cells provide electricity and heat homes and businesses. If used with other renewable energy sources like wind energy, photovoltaic cells can provide enough energy and hence remove the need for energy from fossil fuel sources.

The main problem with solar power is that the sun does not shine at night. The technology that exists now doesn’t take this into account and thus more research needs to be carried out to look for ways of storing energy during the day so that we can use solar energy as a full energy source.

It is quite simple to make the most of free energy home whether you have a pre-established house or you are building a new house. Solar heating systems are simple to build that use standard building materials. However, if you do move into a new house, look for one that makes the most of solar power and solar power technologies. Find a house that has lots of windows in order to keep the sunshine in during winter.

Discover About Renewable Energy System

January 19th, 2010

It is feasible to produce electricity by making the best possible use of natural resources. Most renewable energy resources are obtained from the sun and solar radiation, like energy for heating and electricity, as well as indirect forms of solar energy such as energy from the wind and waves, and geothermal energy that comes from the heat generated inside the earth.

A renewable energy system is a specific technology that has been designed to make use of these continually replenished resources. There are presently some really good systems available. But there are still technologies that need further research and development so that they can replace a substantial proportion of fossil fuel consumption, and thus reduce the overall environmental damages from the use of such fuels and current energy sources.

The power from the sun can be turned into energy directly using a renewable energy system. There are a number of technologies available at this point of time, but not many people are high on the uptake of these technologies. One example of renewable energy system is a solar technology called `solar collectors`. These are what are known as active solar heating, where a solar collector is installed on the roof of a building and collects solar radiation, and produces heat at temperatures usually under 100ºC.

What is usually the case is that people use this renewable energy system for hot water to supply their home for heating up swimming pool and showering. There are a number of energy companies that deal in clean energy who will supply a solar collector for you at a charge, or if you are good with your hands and consider yourself to be a bit of a `handyman’, you can build the technology on your own using materials that you can buy at your local hardware store.

Solar collectors are a very simple renewable energy system. One of the better technologies that make use of the power of the sun’s rays is a solar thermal engine. These follow the same idea as the solar collectors discussed above but the technology is much more developed and thereby much more effective. This renewable energy system uses active solar heating at very high temperatures in order to propel steam to turbines, in order to generate high amount of electricity.

There are a number of renewable energy systems that make use of passive solar heating and this is really crucial as it reduces the energy required for heating a home/area. For example, from a very young age we are told to always open the blinds to let the sunlight in and close them at night just before dusk and before it gets dark. This is common sense, but many people are unaware of the importance of such practices.

A renewable energy system that uses passive solar heating is one of the best ways to take advantage of the consistent energy available from the sun and it is free. There are a lot of building companies that specialize in designing low energy building, that allow your house to maximize the use of passive solar heating. In order to cut down heat demand, homes are designed in such a manner so that the windows allow lots of sunshine in and this is especially important during the winter. Households must also be well insulated and windows double-glazed to keep the home warm in the winter without the need of high levels of electricity. Discuss with your local energy company and building company about what you could possibly do to create a renewable energy system that uses passive solar heating.

Find out how you can make use of renewable energy from our renewable energy website.

Solar Energy Disadvantages

January 10th, 2010

Solar energy has been seen as the answer to all our energy problems because the power we receive from the sun will never run out like that of fossil fuels, and it is also a free resource. But there are quite a number of advantages of solar energy, there are some disadvantages of solar energy to.

One of the main disadvantages of solar energy presently is the fact that there are insufficient solar technologies developed at the moment to fully supply the energy needs of the global population. There are some technologies like solar collectors that can provide some energy to your household. You can make use of solar energy for your hot water systems and water heaters for your swimming pool. However these technologies are very limited in the amount of power that can be supplied to your home. Many people become frustrated with this as they want to make full use of renewable energy, but do not see the benefit of using this when it makes very little difference to your electricity bill and installing such technologies takes so much effort.

One of the other key disadvantages of solar energy is the astronomical cost involved with buying and setting up the technology. You may have heard claims before that solar energy is free energy and if you make use of such a resource you will never have to pay another cent to your electrical provider. This is not true at all and the technology used to setup solar energy is usually just far too costly for most people to even think of such an energy option. Even though energy prices are expensive and the costs keep rising, many people are able to manage to pay a monthly electricity bill as the cost involved is predictable and manageable. However this is not the case with solar technologies as it can cost you up to ten thousand dollars to set up a solar powered hot water system that needs to be paid up front, and even then you cannot be guaranteed that you will not have to pay for traditional electricity as well if the system does not work as well as you wish it to.

There are a number of other disadvantages that prevent people from seriously thinking to spend in such a technology. You may have come across that there is an vast amount of sunlight around us and so it will never run out, however what these theorists have never tell you is that the sun doesn’t shine at night time and what are you going to do to get electricity then if you no longer have the conventional forms of electricity set up in your home. You would still require energy at night to watch the television and make a cup of hot coffee – and many of the solar energy technologies do not take this into account. Before you go ahead to set up solar power systems you will have to take these into consideration, otherwise you will be thoroughly frustrated.

Solar energy sounds too good to be true for the reason that it has been said that it uses the heat of the sun to power your home, and you will never have to spend another dollar on electricity. This is not true. There are some clear disadvantages of solar energy at this point in time. To commence with the technology is a huge initial investment, the technology is not very matured yet, and the sun doesn’t shine 24 hours everyday so you will not have power all the time. Take these into consideration before you embark on your solar energy project.

Solar Systems: Key Issues

December 19th, 2009

Vacuum tubes of ultrahigh thermal conductivity (SV-pipes) are work with the same principle as the ordinary vacuum tubes, and have all the above advantages. But they have some fundamental differences, which significantly increase their effectiveness. Not thermos flask is vacuumed in SV-evacuated tubes, but the entire space of the pipe that reduces heat losses to a minimum. As a result, they continue to operate efficiently down to -50 ° C

Because they use no double but single-glass, pipe wall thickness is increased on 0.5 mm, and it may withstand falling hail of 35 mm without prejudice.

With highly selective absorbent layer such pipes perceive diffusion light, and this means that they will work, even if the sky is overcast, they just loose productivity a little. They are ready to work immediately, as soon as the surface will be fallen with sunlight, and just 3-5 minutes later the temperature at the tip is raised to +100 ° C (maximum – up to +300 ° C). Performance of SV-pipe is about 85%.

Tubular Solar systems supply homes with hot water excellently. They heat swimming pools and greenhouses, make ventilation, air conditioning and heating of buildings work. Depending on the characteristics of the building solar collectors can be installed:

• on a sloping roof;
• on a flat roof or horizontal surface near the house;
• on a sloping wall, oriented to the south;
• be mounted directly to the roof.

The cost and accounting of the system
The cost of a solar collector installing exceeds the cost of equipment for the traditional heating and hot water, but the economic benefits of such solutions are obvious; if we take into account the constant increase in energy costs (for the last two years, gas has risen in price by 300%, and it is possible that we will pay for it at very high prices soon.

Systems are installed on a turnkey basis, that means that their value includes the cost of equipment and work that does not quite belong to the solar system itself, but which is essential to its normal operation (such as installing of battery tank and its binding). On the other hand, setting the heating boiler, the owners also have to pay for its installation. Another argument in favor of solar system is their long life. Solar equipment is very reliable – there are no moving parts, and therefore there is nothing that may break. Manufacturers guarantee that it will be successfully operated for 25 years. For comparison: the electric heater works about 6 years at home, and the boiler works 10 years in average (but you will need to replace the burner so that CPA not fall).

And operating costs are not comparable: Vacuum Solar systems require no maintenance (except the case when you will have to wash it if there is very strong dust). Boilers need to be continuously monitored. You must change the burner periodically, and heating elements in electric boilers. If the boiler runs on gas, you will have to deal with the gas department.

So, it might be not the worst idea to install the solar system in your household.

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 real case proof of it. If you want to switch to solar energy, please find out more about how solar power grants and how exactly you can exploit these solar power grants for your living.

P.S. Good information makes life easier.

Due to this if you are properly armed with the information in your sphere of interest you can be sure that you will always find the way out from any bad situation. So, please make sure to get back to this blog on a regular basis or – an ideal solution for you – sign up to its RSS. Thus you will have your hand on the pulse of the latest info updates here. Blogging can be helpful, you just need to understand how to use it.

Flat Solar Collector: Characteristics And Components

December 17th, 2009

The main component of the flat collector is a copper absorber with selective coating, which provides a high level of absorption of solar energy and low emission of thermal energy. Copper tube is installed at absorber and coolant flows through the former. It may be water or some non-freezing liquid, which takes heat from the absorber and simultaneously with circulating through the coil, it accumulates in the accumulation tank (the tank with water).

The absorber body is protected by a collector with a reinforced insulation that also minimizes heat loss. The amount of solar radiation that reaches the surface of the solar collector reaches its maximum only at noon when the sun is at its zenith. Speaking about morning and evening, sunlight falls on it at an angle, and the amount of absorbed solar radiation decreases.

Flat collectors do not work in winter, because even with a two-system` antifreeze, the maximum allowable operating temperature is about -5 ° C. With further lowering loses of heat reduce the result to a level of zero. The more solar collectors absorb solar energy and the less they lose it, the more efficient the system will work. Efficiency of the collector shows what percentage of solar radiation that falls on its base surface, can be converted into useful thermal output. This indicator is volatile and can be determined only in the specific operating conditions in a single moment in time. The lower the temperature to which you want to heat the water, the more efficiency is. Modern flat solar collector work with an average working efficiency of 50%, more obsolete models work with 20-40% of it.

And now we will compare flat collectors with those of high-vacuum tubes type. Their employment is based on a simple principle of a heat pipe, which is a hollow brass rod, soldered at both ends with the extension in the upper part. Non-toxic reagent is inside of it; it evaporates during boiling and in the form of vapor rises into the upper part – into the tip, where the temperature can reach 250 ° C. And it is condensed there, giving warmth, and condensate flows down the walls of the tube, and the process repeats then.

Heat removal can be carried out in different ways, for example, directly from the tip through the glass, soldered to the pipe through which the solar fluid flows. In a closed-circuit it can be freezing liquid-based glycol (warmth comes to storing tank), in an open system it may water (it goes directly into the boiler). Whatever it were, immediately after the absorption the heat is given to the coolant and does not go into the environment. This is the key difference between heat pipes and flat solar collectors.

The effectiveness of heat pipes with U-shaped tubes (the most simple, used in tubular systems) is a cut above that of flat collectors. Due to its cylindrical form, they work fine during the day, because their surface is always illuminated by the sun. This results in a stable energy at different angles of incidence of sunlight. The tubes are well protected from the adverse effects of nature (hail, wind and other things), but in any case, such systems also have weaknesses.

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 use them and where you can find these solar power grants.

P.S. Good information quickly enhances the quality of our life.

Due to this if you are properly armed with the knowledge in your sphere of interest you can rest assured that you will always find the solution to any bad situation. So, please make sure to track this blog on a regular basis or – the least time consuming way of doing it – sign up to its RSS.

Why It Is So Important To Use Solar Power?

December 7th, 2009

It is generally known that one of the major factors in the civilization development is the energy sources use. We basically use traditional energy resources, such as – oil or coal and natural gas. This causes great environmental pollution of our common home called Earth. Hundreds of thousands of barrels of oil are being merged into the ocean, millions of tons of carbon dioxide are being emitted into the atmosphere, four hundred nuclear power plants produce tens of tons of radioactive waste.
Moreover, it is not only about pollution. The stocks of these traditional sources are not infinite. Therefore, they are referred to non-renewable energy sources.
Solar energy is widely used for water heating and for electricity production. The solar collectors are made from available materials such as steel, copper, aluminum etc. They are being processed without the use of scarce and expensive silicon. This reduces the cost of equipment and energy produced by it significantly. At present time, in particular, solar water heating is the most effective way of solar energy converting.
In 2001, the cost of electricity produced in solar collectors was $ 0.1 – $ 0.11 per kW • h. U.S. Department of Energy predicts that the cost of electricity produced by solar concentrators will drop to $ 0.38 – $ 0.46 within 2015-2020.
In 2007, Algeria began the construction of hybrid plants. In the daytime electricity is being taken from the parabolic concentrators and from natural gas at night.
Solar collectors can be used in cooking. The temperature in the collector focus may reach 140-150 ° C. These dishes can be widely applied in developing countries. The price of materials used for “solar kitchen” manufacture is about $ 4 – $ 6. Wood is also widely used for cooking in developing countries.
Traditional pockets for cooking have thermal efficiency of about 10%. The use of firewood for cooking leads to massive deforestation. For instance, more than 65 million tons of CO2 gets to the atmosphere from the burning of biomass in India annually. In Uganda, the average monthly household consumes 450 kg of firewood.
While cooking, housewives inhale large amounts of smoke that leads to an increase in the incidence of respiratory tract. According to the World Health Organization in 19 countries in sub-Saharan Africa, Pakistan and Afghanistan 800 thousand children and 500 thousand women died from respiratory disease in 2006.
There are various international programs for solar kitchens` distributing. For instance, Finland and China signed an agreement on delivering of almost 20 000 solar kitchens in 31 villages in China in 2008. This will reduce CO2 emissions by 1.8 million tons in 2008-2012. In the future, Finland will be able to sell quotas for these emissions.
One of Swiss companies has developed a technology for producing hydrogen from water using parabolic solar concentrators. Square of mirror installation is approximately 94 m2. Focus concentrator’s temperature reaches 2100 ° C. Water begins to split into hydrogen and oxygen at temperatures over 1700 ° C. During daylight hours (about 6.5 hours that is to say 6.5 kW • h/m².) more than 94.9 litres of water can split into hydrogen and oxygen on the plant. Hydrogen production will be 3700 kg. annually (about 10 kg. per day).

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 get these solar power grants.

Will The Humanity Use Solar Collectors In The Future?

December 4th, 2009

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.

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.

P.S. Good information quickly enhances the quality of our life.

Solar Collectors And Tanks

November 27th, 2009

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.
