Solar water heating takes place via solar energy that is used to heat the water. The water is then stored in a container. Solar geysers comprises of a water storage tank, a solar thermal collector and a liquid system which transfers the heat from the collector to the tank. There are two chief types of collectors which are used. The first being a vacuum tube which consists of a series of glass tubes, which are linked together. The second type of collector is a flat plate collector which has a transparent cover consisting of a carefully insulated weather proof casing, coated metal absorber plate and an especially thickened glass. Solar geysers should best be installed on top of rooftops should the structure be able to carry the additional weight. It is able to link the geyser to an existing heater it can stand on its own, and be positioned elsewhere than the rooftop if required. Remember that wherever you place your solar geyser, that the collector should be placed in a position where it will be exposed to plenty of sunlight.

Solar geysers remain one of the most economical ways to effectively reduce your monthly electricity costs and heat water. When properly installed by professionals, solar heating systems are nearly maintenance free. Solar geysers are even able to heat your pool. The increasing popularity of solar heating systems is indicative that more and more people are discovering the benefits such heating systems hold for them.

Cut Expenses On Home Power By Doing Your Investigation On Solar Energy Options

August 6th, 2010

When talking about solar, it means by the application of power from the sun which heats your water to make it warm. It’s a system where in commonly made of solar thermal collectors, a water storing tank. It works through interconnecting of pipes and fluid system to advance the heat from the gatherer to the tank. The water can be warmed for a wide dissimilarity of uses, including business, home and industrial goals. Solar water heater conserves energy and not only that, you can also save on some finances from your electric bills. The usual examples of solar water heating is the heating of swimming pools, energy input for space heating or even cooling, and under floor heating. Solar water heater applies heat from the sun straightforwardly, not by converting it into electricity. It’s the solar collector that is placed in the movement where it will catch the most sun during day. The water is either triggered by pumped from the collector and back to the water tank by the utilization of piping. It transfers heat from the solar collector to the water and then into the water kept in the tank. That’s how solar system works when it comes to solar water heater.

Save on home power better by doing your investigation on what kinds of diy solar panels and relevant equipment are the most efficient for your kind of situation. On bounded set spaces, highly effective mono-crystalline solar cells are suggested, although you can always utilize them on larger spaces if you have the finances for them or use thin-film amorphous cells for areas with partial shading. Search for equally superior mounts, ideally those that are certified to resist cyclones and wind storms, and sine wave converter to prevent the wastage of DC electricity and guarantee full efficiency of your solar power system. But, do not be too worried about the effectiveness ratings since solar energy is practically an infinitely free source of energy. It doesn’t matter of what environmental groups and advocates will tell you, a 60-watt solar cell will produce 60-watts of AC electricity through a real sine wave inverter.

You should be more concerned about whether or not the solar energy systems you are looking into for meet the feachures they claim to have. Look for certifications from the Environmental Protection Agency or other independent establishments that attest the effectiveness and security of these products. It is important that you look around first before deciding on what brand of solar panels to buy. Compare prices and the length of warranty periods for these supplements and take your option. And although high costs do not without fail translate into high quality products, do not be cheated by inexpensive prices offered by startup alternative energy organizations. Smaller organizations can use lesser| not as great quality materials to lessen costs and permit them to match up to these competitive prices.

Get The Advantages With Straightforward And Unhampered Access To Full Sunlight

August 5th, 2010

Solar water heating, otherwise popular as solar water heater, is water turned hot by solar energy taken from sunlight for commercial, industrial or residential things. Solar water heating systems are included of a water storage tank, heat transfer fluid (HTF), and solar thermal gatherers. How this water heater function? Solar hot water devices are obtainable in two alternatives: active (pumped) or passive (compact). The solar collector, attached to a wall facing the sun or a roof, warms up heating to the liquid that is then circulated through an active heater or propelled to the action by convection in a passive system. Gatherers are composed of an insulated box with a glass covering with a black painted, solar metal absorber that is flat and attached to the copper pipes, or some metal tubes enclosed by a near vacuum evacuated cylinder of glass. Heat is kept in an cushioned water storing tank with valve and vent attached to and out of the collector. Passive or active house solar water heaters comprise of a secondary energy-source (electricity or gas) switched on sunless days to assure a stable hot water supply once tank water plummets under a particular temperature, typically of fifty five Celsius.

Think of home solar panels as an investment for a immaculate, greener, and more energy efficient home for you and your kids in the future. In many places in the United States, taking into account California, Arizona, Colorado, and New Jersey, people are offered with generous incentives to let them buy solar panels and have them set to promote solar energy efficiency. Over the last half of the century, the prices of solar panels have dropped significantly, most likely owing much to the higher understanding in the requirement for renewable forms of energy to save home energy and the environment. How to obtain solar energy with the use of solar panels? Energy from the sun attains the Earth for free, but there are certain costs and equipment required for us humans to take advantage of this illimitable source of renewable energy and turn it into a more usable form-electricity. Here enters the idea of photovoltaic technology, when a semiconductor could convert sunlight into direct present electricity.

At the present time, this technology is straightforwardly applied to the utilization of solar cells mounted on houses rooftops, building tops, or anywhere with direct and unhampered access to entire sunlight. A contemporary solar panel is consisted of different solar cells, which are made of silicon, a natural semiconductor that produces direct present electricity. When sunlight attains the solar cells, the silicon plate absorbs the radiation and stimulates an influx of electrons. This flow of electrons is thought as straightforward current electricity, which can be converted into alternating current electricity and transferred to your home with the use of an effective sine wave inverter.

You can heat water for numerous objectives, which contains home, industrial and business. Some of the general places where solar heating is using include swimming pools, under floor or for offering energy source for cooling or heating a particular space. Domestic solar panels are generally used to warm water at home. These solar water heating systems use solar panels called flat plate collectors, which is placed on the roof of the building. A boiler can be applied when these panels do not heat up the water to the expected level. The advantages of these domestic panels are that we can get hot water throughout the year. This will lessen the hot water costs. Since solar energy is free from pollution it doesn’t have any harmful substances or pollutants.

The diy solar panels must be kept in a place where there is straightforward sunlight. The panels always need not be built in the roof they can even be fixed on flat roofs. A domestic solar panel applies a dual-coil cylinder; it has a boiler and the solar panels. The other components that are used contain pump, hot water cylinder, and controller. The precise working of this domestic panel lies here. The solar energy is collected by the solar panel. The heat produced is passed through the pipe to the hot water storing cylinder. Heat is produced by the pump that is circulating the water to the coil in cylinder. This heating system has a controller to keep track of the flow of power from the panel to the storage cylinder. The customary boiler raises the heat produced by these panels as and when required.

What Is A Solar Geyser?

May 30th, 2010

If you have been living in South Africa in the last 15 years, chances are very good that you’ve been hearing about solar and renewable energy. Corporate companies such as Eskom and Government has been urging people to use electricity wisely and conserve wherever possible. Eskom has even gone as far as to subsidize solar geysers for South African households in an effort to raise the nation’s participation in saving electricity. But what is a solar geyser? And what benefit does it hold for the everyday South African household?

Solar water heating, or solar hot water is water heated by the use of a solar geyser. A standard solar geyser generally consists of a solar thermal collector, a water storage tank and a fluid system to move the heat from the collector to the tank. Solar water heating works by expressly heating liquids through the sun’s power, and no electricity is directly generated. It may perhaps use electricity for pumping the fluid, and have a reservoir or tank for heat storage and later use. The water heated in this way may be used in a variety of ways such as for heating swimming pools, under-floor heating or even power input for space heating.

The water moves around a solar heating system either by passive circulation, or by means of pumps (forced circulation). In passive circulation, the water heats up in the collector and rises naturally into the storage container above it, while the cooler water in the storage container flows down to the bottom of the collector, creating an unaided circulation. In order for this system to work effectively and to avoid reverse circulation at night the collector must be placed below the geyser. This sort of system can be supplied with an inherent freeze resistance by using a closed circuit between the collector and the geyser. Forced circulation systems work with a pump that keeps the heat transfer fluid circulating between the collectors and the heat exchanger in the storage container. The pump itself is controlled by a differential controller. The pumps in forced circulation systems are small, and thus do not need or use much power.

ENSAV is a new lead-generating system for energy saving solution suppliers such as solar geysers, solar pool heating, heat pumps and more. ENSAV will find you multiple quotes from one query, and there is a great ratings system in place to help you the client find the best service provider the first time, every time.

Solar Hot Water Is Just Not For The Home!

April 7th, 2010

Solar thermal systems are mainly used for the provision of standard domestic hot water. A solar water heating system is an energy efficient way to provide domestic homes with up to 70% of their hot water supply.

However there are a number of other ways that these systems are being utilised by forward thinking designers and householders seeking to deliver greener alternatives to energy problems.

Heating homes with solar hot water

Solar panels coupled with a thermal store can be used to provide small areas of underfloor heating. However, before fitting the system there are some important calculations to be carried out. The area that requires heating will dictate the number of solar panels needed, and the quality of existing insulation will also impact on the effectiveness of the system. The better the insulation the less heat will escape keeping the room nice and warm without placing excessive demands of the system.

Calling on the expertise and wisdom of a renewable energy expert to carry out these calculations, will help avoid making mistakes that effect a solar thermal system’s overall performance.

Most solar hot water systems are not suitable for powering domestic radiators as they struggle to keep up with the speed that a radiator gives up its heat. To heat a whole home using renewable energy, solar photovoltaic systems are currently a much better alternative.

Solar thermal pool heating

Anyone lucky enough to own a swimming pool will know that they generate huge water heating bills. But by installing solar water heating these costs can be cut by up to 70 – 80%.

Small or large, indoors or outside, solar thermal panels can be used to heat swimming pools. The heating system works with existing boilers and heat exchangers to produce a base load of natural heat to dramatically reduce running costs.

Another advantage of a solar thermal pool heating system is that once installed it costs very little to run. All that is required is a pump and controller which itself requires minimal electrical power (which could be obtained from a solar PV panel).

Large scale solar water heating systems

Solar water heating is not just for domestic use. Clever designers are finally looking seriously at larger scale solar thermal systems for apartment blocks and commercial properties.

The principals for these larger systems are fundamentally the same as with the smaller scale solar water heating systems but the execution is on an altogether different scale Massive constructions and heavy duty elements are required when you scale up from a domestic tank of hot water to a system that might need to supply hundreds of people with thousands of litres of hot water in a day. The good news is that these larger systems are already proving their worth and economies of scale mean that they provides a much faster return on investment.

A word of advice

Before making any investment into renewable technology it is always a good idea to get professional advice. Talk to an alternative energy expert about what you want to use renewable energy for, and give them some details about the location where you want to use it. From this they can provide you with an idea of which technology is suitable and any alternatives that might be on offer. Thus saving you the cost and effort of installing a solution which proves to be unsuitable and unproductive for your needs.
