Experts discuss the advantages of Evacuated Solar Thermal over Flat Panel Technologies. Powered by the sun, large scale commercial water heating is now profitable and reliable.

The owner, Garret, of Suncity Solar Energy is installing a water tank and hooking it up to the other tank. He explains the circulation of the water in the process of heating and storage.

Swimming pool solar heating is an acceptable option to keeping your pool warm throughout the year. It relies upon the method of heating water through a chain of solar panels which are exposed to sunlight, and absorb the heat. It is not based on photoelectric cells which generate electrical energy from sunlight, instead it’s a way more direct conversion of heat in daylight to heat in water.The water is fed through the solar cells by the pool pump. The solar panels can be installed on the roof of your place, or they can actually be installed at ground level in a bracket. The roof level panels are out of the way and not taking up any space in your garden, but the water may need a booster pump to help it battle against gravity on the way up. Either way you’ll need to angle your solar energy panels so that they face the sun properly for your latitude. In the northern hemisphere, this implies that your panels meet face to the south. In the southern hemisphere it is the other way round.But what occurs on very hot days? Does this water continue to heat up till the pool is uncomfortably hot or perhaps dangerously hot? No, the solar system has a thermostatic controller which makes sure the temperature of the pool does not go too high. When the temperature is just right, the water is not diverted through the panels, so no additional heat is added to the pool. Alternately, you could transfer the water to heat a water tank, which can then be used for other household wants, but this is not compulsory.Because the daylight is less intense during winter months, pool solar heating alone is not good enough to keep your pool hot all year round. It would definitely forestall freezing, but to get pleasantly warm water in the winter months you might need to help your solar energy panels with a more conventional heater like a gas powered heater. However, the solar powered system would pay for itself because it is so much cheaper to run than the gas heater, that will only need to be used now and then.Whichever route you used to heat your pool, you must definitely get a pool cover and use it to keep heat in when the pool isn’t in use. The majority of the heat that is lost from the pool system is lost from the surface of the pool itself. Employing a cover to preserve the heat can split your heating bills!.

What is a Solar Panel? It can be defined as a contrivance/device that has capabilities to convert photons of light (a photon is an indivisible unit of electromagnetic radiation) emitted by the Sun and convert it into usable electric energy. It is also known as a “Photovoltaic” panel or module, (a module, in scientific terms, is referred to as “a set of parts or units that can be utilized to develop a more complex structure”). The basis of this energy is the Sun. Sun is an immense globe of gas that is seamlessly emitting out energy in the form of Heat and Light. Solar energy collectors utilize the sun’s energy, which is made up of particles of energy known as photons, and convert it into electrical energy inside a photovoltaic cell or solar cell, which can be used to energize electrical loads. How does a Solar Panel work? A semi-conductor, (substances that conduct electricity only under certain conditions) mainly Silicon is used to absorb the photon from the sun’s rays and convert it into electricity. How? At the basic level, two thin sheets of silicon are used, one is “doped” (it is an addition of other elements (impurities) to a semi conductor so as to conduct electricity smoothly) with ‘phosphorous’ and arsenic (5 electrons per atom), which introduces a free electron, to the semi conductor. This is known as an N-type (Negative-Type) semi conductor. Another silicon sheet doped with small amounts of boron (three electrons per atom) leaves a missing electron in the semi conductor. This missing electron leaves a hole making the semi conductor positive and acts as a conductor. This is P-type (Positive-Type) semi conductor.

The principle is simple. When these “doped” thin sheets of silicon are sandwiched together, an electric field is created. If we establish a conduction pathway on the electric field so created by placing a contact grid on the top and bottom of N-Type and P-Type silicon sheets, the electric activity is stepped-up between the “doped” silicon sheets causing a flow of electricity through the pathway. This is a most rudimentary type of Photovoltaic cell capable of generating 0.75 to 1.5 watts of electricity. To light a small home, one needs a bank or array of cells depending upon the expected usage. Benefits of Solar Panels: (1)   You are not dependent on Electric Utility Grid. (2)   This spells huge financial savings. (3)   You can live in remote, eco-friendly neighborhoods with Solar Panels providing electricity very cheaply. (4)   Solar power is renewable energy and is very clean and eco-friendly. Functionally they are superior. (5)   Maintenance costs are extremely low. (6)   Solar Panels are very compact, more especially those meant for homes. Every integral part and every accessory of the unit is so designed as to make assembling the whole a very interesting and at the same time extremely easy for the D.I.Y segment. Market prices of a whole unit would be prohibitive. Besides, the price of the unit, the installation expenses by technicians would be a very costly affair. If you purchase the parts and assemble it yourselves, the cost becomes negligible. FOR SOLAR PANELS, D.I.Y. is the way! The easy way! (7)   Since, solar power is working, NOT ON AC (alternating current) but on DC (direct current), principle, your computers, home appliances which work on DC need not use adapters, avoiding conversion leakage which is common. (8)   No hassles in paying Electricity Bills. In fact there is no bill. (9)   The critical factor is the duration and effectiveness of sun in your area. Other uses of Solar Panel: Solar energy can be transformed into Heat energy. a)      Heating of Homes in winter at a very reasonable rate. b)      Heating water in bathrooms and swimming pools. Compared to AC system, the Solar Panels will provide heating to such appliances very cheaply. c)      Washing machines and Dishwashers also can be connected to the Solar Panels.

Tax Benefits: v      On 4th February 2008, The Energy Policy Act of 2005 was allowed to cover almost all homes in the US. This means you can claim tax credits if you have constructed a new house using Solar Panels. The Emergency Economic Stabilization Act of 2008 bestows tax credits for people planning improvements in 2009. The Energy Policy Act of 2005 placed a $2000 credit cap on certain types of Solar Panels. The Emergency Economic Stabilization Act of 2008 eased this cap on Solar Panels. This means if you buy a Solar Grid Panel for $20,000 your tax credit will be much more than the $2000 credit allowed previously. v      The states of New York, Washington, Florida, Minnesota and Vermont do not charge any Sales Tax on Solar Panels and their parts. v      The State of California permits you to deduct any interest you may have been paying on energy loans in your tax returns. v      The states of Virginia and Texas won’t add the value of Solar Panels in your property value. This means that there is no Property Tax on your new Solar Panels. v      The States of South Carolina, Arizona and New York allow an extra deduction of 25% tax credit on the value of the solar system operating in your home. v      The State of New Mexico, the most friendly renewable energy loving state allows its residents a $9000 tax credit, if the resident installs a Solar Panel system. Renewable energy is the future of the globe. It is inexhaustible as long as the sun lives, which is estimated to be many more billion years! No eco-debilitating gases, no global warming, no hole in the ozone layer, no increase in El Nino effect. The existence of water vapor and carbon-di-oxide, which keeps the heat coming from sun in equilibrium, is altered by excessive release of carbon-di-oxide. This is known as Greenhouse Effect. By using renewable energy whole-heartedly, and on a global scale, our eco-system will regain its balance obviating the perils and upheavals waiting to happen.

D.I.Y. System: It is very simple. What you need is the right mind-set. Henry Ford said: “If you think you can, or if you think you can’t, you are right….” If you think you can, D.I.Y. system makes it even simpler for you to achieve. Great things are achieved not by knowing everything; in fact great things are achieved only by putting your heart into it.

To truly understand the benefits of green solar energy, you must first understand how solar energy is harnessed. There are two types of green solar energy-thermal and light. Thermal energy is considered passive solar. This type of green solar energy is harnessed through the design and materials used to construct a building. By integrating south facing windows and materials that retain heat, like brick and stone, you can lower your energy needs and build an energy efficient structure. The thermal energy produced by green solar energy is also used to heat water for solar hot water systems. The rays of the sun also produce light and radiation that can be captured by solar panels to create electricity.

The most popular use of green solar energy is for saving money. Although green solar energy systems can come with a large initial investment, they generally pay for themselves in a few years by providing either supplemental electricity or all of the electricity to your home or business. Building your own solar panels, participating in government refunds and net metering, in which you sell unused electricity back to the power company, can reduce the cost of implementing a green solar energy system. In addition, green solar energy systems require little to no maintenance after installation, as most have no moving parts.

The most important benefit of utilizing green solar energy is completely environmental. With polar ice caps dwindling away and climate changes creating tragic storms world wide, it is increasingly obvious that steps must be taken to decrease global warming and our dependence on fossil fuels. Green solar energy provides a clean energy alternative as it creates little pollution and does not contribute to global warming.

Solar energy panels have become more affordable in recent years making it a viable alternative energy option for savvy home owners looking for savings on their monthly utility bills and the environmentally conscious who also enjoy the financial advantage, but focus more on the benefits solar energy panels have on global warming and independence from fossil fuels.

If you are a beginner to the solar electric world, then you may be wondering what exactly solar energy panels are? It is really simple and yet fascinatingly complicated. Solar energy panels are also known as photovoltaic panels; photovoltaic meaning electricity from the sun. Solar energy panels work by collecting protons from the sun, which displace neutrons, and create a flow of electrons or electricity. An inverter converts the power generated by the solar energy panels from an AC current to a DC current making it usable in homes as a direct electricity supply.

You can use solar energy panels to heat your pool, workshop tools, greenhouse lights and fans or depending on you personal electric usage, your entire home or business. Most solar energy panels are designed to last 30-40 years and require little to no maintenance. Over the life-span of solar energy panels, the energy savings realized by the owner is enough to justify the initial cost of the system and prices are dropping more and more as a larger number of consumers express interest and make the change to solar energy panels or other renewable resources.

Solar energy panels for small applications can be purchased at your local hardware stores. These small versions are ideal for outdoor lighting, small water pumps and other outdoor tools. If you are purchasing a home size or business size system of solar energy panels it would be best to seek out a local retailer of solar energy panels or a green energy retailer in your area. There is also plenty of information available online about different solar energy panel providers.
