Solar Pool

July 14, 2011 By: Admin Category: Solar Heater

Solar Swimming Pool

Shallow water in a pond or lake tend to be more heat than the water that is in a deeper place. This occurs because the sun can warm a basic pond or lake in the area that is more shallow, and that means water that is above become hot.

With the same principle, the sun can be used as a water heater in the building and swimming pool. Most of the water heating system that uses the sun as a source of heat, consists of two main parts: the sun collectors and storage tanks. Collectors that are commonly used flat plate collectors. Collector consists of thin flat box with a transparent top cover part and facing towards the sun. Small pipes that is in the box bring liquids, which can be water or other liquids, to be heated. Pipes is paired on the black plate that serves to absorb heat from the sun. After a heat form in the collector, the liquid is in the pipes will be hot.

Firefly by Vuk Dragovic

Firefly is a table that is designed for the parts outside the restaurant, cafe or even homes. This table does not needs a candle because it has inbuilt lights that charge during the day using solar power. In the daytime, the lamp located within the center radius of the table. When night comes, the top of the lamp is pressed, the lights came out and began to emit light at the top of the table. The underside of the lamp located above the stencil from the cafe choice (or selection of tables manufacturers) so the text or logo is projected onto a table leg. This design innovation is the fusion of tables function, extraordinary form and the message that the lamp project to the foot of the table. That message can be anything, from a logo or slogan of a company (because we are in the era of the dominant advertising) to the intimate messages, pictures or symbols. [Via]

Solar Applications

June 21, 2011 By: Admin Category: Solar Power

Solar Energy Applications

Solar energy technologies use energy from the sun to produce heat, light, hot water, electricity, and even cooling, for homes, commercial and industrial.

There are a variety of technological applications that have been developed to take advantage of solar energy. Technology can be read further below.

Photovoltaics System

Solar cells work by converting sunlight directly into electricity. The electrons in the semiconductor material, the material used to capture sunlight, will move when the sun’s energy in the form of photons hit it. Solar energy is forcing the electrons to move, occur continuously, and consequently there is also a continuous electricity production. Process, which turns sunlight (photons) into electricity (voltage), called the photovoltaic effect.

Solar Cell Module

Solar cells are usually organized into modules that each module can consist of 40 solar cells. Some modules can be arranged to form a PV line fitted with a fixed angle facing south. Or even could be placed in a sun-tracking device, to get more solar energy throughout the day. Several rows of PV could produce enough power for a house. As for industrial applications or power companies, hundreds of lines of PV can be linked to form one large PV systems and sufficient to meet the electricity needs.

Thin Film Solar Cell

Thin film solar cells use several layers of semiconductor material with a thickness in the micrometer scale. Technology allows to create solar cells integrated into rooftops to the skylights. Even solar cells are designed for applications having the same power with actual roof.

Glitter-sized Solar Photovoltaics Produce Competitive Results

Adventures in microsolar supported by microelectronics and MEMS techniques

photovoltaic cells micro Photovoltaic Cells

Representative thin crystalline-silicon photovoltaic cells – these are from 14 to 20 micrometers thick and 0.25 to 1 millimeter across.

Sandia National Laboratories scientists have developed tiny glitter-sized photovoltaic cells that could revolutionize the way solar energy is collected and used.

The tiny cells could turn a person into a walking solar battery charger if they were fastened to flexible substrates molded around unusual shapes, such as clothing.

The solar particles, fabricated of crystalline silicon, hold the potential for a variety of new applications. They are expected eventually to be less expensive and have greater efficiencies than current photovoltaic collectors that are pieced together with 6-inch- square solar wafers.

The cells are fabricated using microelectronic and microelectromechanical systems (MEMS) techniques common to today’s electronic foundries.

Sandia lead investigator Greg Nielson said the research team has identified more than 20 benefits of scale for its microphotovoltaic cells. These include new applications, improved performance, potential for reduced costs and higher efficiencies.

“Eventually units could be mass-produced and wrapped around unusual shapes for building-integrated solar, tents and maybe even clothing,” he said. This would make it possible for hunters, hikers or military personnel in the field to recharge batteries for phones, cameras and other electronic devices as they walk or rest.

cells photovoltaic nielson Photovoltaic Cells

Sandia project lead Greg Nielson holds a solar cell test prototype with a microscale lens array fastened above it. Together, the cell and lens help create a concentrated photovoltaic unit.

Even better, such microengineered panels could have circuits imprinted that would help perform other functions customarily left to large-scale construction with its attendant need for field construction design and permits.

Said Sandia field engineer Vipin Gupta, “Photovoltaic modules made from these microsized cells for the rooftops of homes and warehouses could have intelligent controls, inverters and even storage built in at the chip level. Such an integrated module could greatly simplify the cumbersome design, bid, permit and grid integration process that our solar technical assistance teams see in the field all the time.”

For large-scale power generation, said Sandia researcher Murat Okandan, “One of the biggest scale benefits is a significant reduction in manufacturing and installation costs compared with current PV techniques.”

Part of the potential cost reduction comes about because microcells require relatively little material to form well-controlled and highly efficient devices.

From 14 to 20 micrometers thick (a human hair is approximately 70 micrometers thick), they are 10 times thinner than conventional 6-inch-by-6-inch brick-sized cells, yet perform at about the same efficiency.

100 times less silicon generates same amount of electricity

“So they use 100 times less silicon to generate the same amount of electricity,” said Okandan. “Since they are much smaller and have fewer mechanical deformations for a given environment than the conventional cells, they may also be more reliable over the long term.”

Another manufacturing convenience is that the cells, because they are only hundreds of micrometers in diameter, can be fabricated from commercial wafers of any size, including today’s 300-millimeter (12-inch) diameter wafers and future 450-millimeter (18-inch) wafers. Further, if one cell proves defective in manufacture, the rest still can be harvested, while if a brick-sized unit goes bad, the entire wafer may be unusable. Also, brick-sized units fabricated larger than the conventional 6-inch-by-6-inch cross section to take advantage of larger wafer size would require thicker power lines to harvest the increased power, creating more cost and possibly shading the wafer. That problem does not exist with the small-cell approach and its individualized wiring.

photovoltaic cell group1 Photovoltaic Cells

From left to right, Sandia researchers Murat OKandan, Greg Nielson, and Jose Luis Cruz-Campa, hold samples containing arrays of microsolar cells.

Other unique features are available because the cells are so small. “The shade tolerance of our units to overhead obstructions is better than conventional PV panels,” said Nielson, “because portions of our units not in shade will keep sending out electricity where a partially shaded conventional panel may turn off entirely.”

Because flexible substrates can be easily fabricated, high-efficiency PV for ubiquitous solar power becomes more feasible, said Okandan.

A commercial move to microscale PV cells would be a dramatic change from conventional silicon PV modules composed of arrays of 6-inch-by-6-inch wafers. However, by bringing in techniques normally used in MEMS, electronics and the light-emitting diode (LED) industries (for additional work involving gallium arsenide instead of silicon), the change to small cells should be relatively straightforward, Gupta said.

Each cell is formed on silicon wafers, etched and then released inexpensively in hexagonal shapes, with electrical contacts prefabricated on each piece, by borrowing techniques from integrated circuits and MEMS.

Offering a run for their money to conventional large wafers of crystalline silicon, electricity presently can be harvested from the Sandia-created cells with 14.9 percent efficiency. Off-the-shelf commercial modules range from 13 to 20 percent efficient.

A widely used commercial tool called a pick-and-place machine — the current standard for the mass assembly of electronics — can place up to 130,000 pieces of glitter per hour at electrical contact points preestablished on the substrate; the placement takes place at cooler temperatures. The cost is approximately one-tenth of a cent per piece with the number of cells per module determined by the level of optical concentration and the size of the die, likely to be in the 10,000 to 50,000 cell per square meter range. An alternate technology, still at the lab-bench stage, involves self-assembly of the parts at even lower costs.

Solar concentrators — low-cost, prefabricated, optically efficient microlens arrays — can be placed directly over each glitter-sized cell to increase the number of photons arriving to be converted via the photovoltaic effect into electrons. The small cell size means that cheaper and more efficient short focal length microlens arrays can be fabricated for this purpose.

High-voltage output is possible directly from the modules because of the large number of cells in the array. This should reduce costs associated with wiring, due to reduced resistive losses at higher voltages.

Other possible applications for the technology include satellites and remote sensing.

The project combines expertise from Sandia’s Microsystems Center; Photovoltaics and Grid Integration Group; the Materials, Devices, and Energy Technologies Group; and the National Renewable Energy Lab’s Concentrating Photovoltaics Group.

Involved in the process, in addition to Nielson, Okandan and Gupta, are Jose Luis Cruz-Campa, Paul Resnick, Tammy Pluym, Peggy Clews, Carlos Sanchez, Bill Sweatt, Tony Lentine, Anton Filatov, Mike Sinclair, Mark Overberg, Jeff Nelson, Jennifer Granata, Craig Carmignani, Rick Kemp, Connie Stewart, Jonathan Wierer,

George Wang, Jerry Simmons, Jason Strauch, Judith Lavin and Mark Wanlass (NREL).

The work is supported by DOE’s Solar Energy Technology Program and Sandia’s Laboratory Directed Research & Development program, and has been presented at four technical conferences this year.

The ability of light to produce electrons, and thus electricity, has been known for more than a hundred years.

The Basic Facts Of Solar Battery

batteries for solar Solar Batteries

Solar power is an effective way to harness the power of the sun, the plants have been doing this for millions of years. Solar energy is cheap, reliable and can produce tremendous power, but only in the daytime. This is the main problem of solar energy utilization. The average home will use less power during the day, and much smaller in the summer which is the peak power (fastest time) for solar panels to generate energy. To be effective this power should be stored.

One popular way to store solar power is to connect the solar panels to the electrical grid, which effectively turn it into a battery. This allows excess energy to be sent back to the electric company, actually make the electric meter run backwards. At night, the power drawn from the grid as usual. This is only as reliable as the existing grid. Each power outages could still affect these solar panels, but no rechargeable batteries should be used.

Rechargeable batteries are known for having a short age, and expensive. They also have low power flow for a long time with good capacity, or they have a high power electrical short time with the poor capacity. Typical batteries, especially lithium ion, has a high capacity to store power, but provides a weak output and recharge slowly. An ideal solar battery will be able to charge quickly, has a high density to save power and can emit as much power as needed. This ideal combination is something that no battery has been able to do until now. It can only be done through the study of nanotechnology.

Researchers at the University of Maryland have developed a way to create a very powerful battery, the dense refill using nanotechnology. Individual parts, which looks surprisingly like a photovoltaic panel is only a thousand times smaller, is assembling his own, self-replication, and aligning itself too. There is no mechanical process can achieve anything similar small, which also contributes to their relatively low cost. They are still in the testing stage and court, but should look widely and production operations in a year. Able to store the power created from sun and wind will soon make fossil fuels obsolete and mysterious.

Solar Photovoltaic: Future Energy Sources

In general, energy sources are categorized into two parts namely non-renewable energy and renewable energy. Fossil energy sources are among the first group that the bulk of activity in the world using these conventional energy.

It is no doubt that the solar photovoltaic is one source of environmentally friendly energy and is very promising in the future, because there is no pollution produced during the process of energy conversion, and more widely available source of energy in nature, namely the sun.

Fundamental issues in solar cell technology is a very low efficiency in turning solar energy into electrical energy, which to date the highest efficiency can be achieved no more than 20%, and even then in a laboratory scale.

For that in developed countries, research on solar cell is a very big concern, especially with the issue of environmental clean.

From light into electricity

In a simple solar photovoltaic consists of the p-type and n junction semiconductor material (pn junction semiconductor) that if by the sun there will be a flow of electrons, electron flow is well known as the electric current flow. While the structure of the solar cell is as shown in Figure 1.

solar photovoltaic1 300x220 Solar Photovoltaic

Figure 1. Structure of a thin layer of solar photovoltaic in general

The main part of the energy changes of sunlight to electricity is the absorber, however, each layer is also very influential on the efficiency of the solar cell. Sunlight consists of various types of electromagnetic waves in a spectrum can be seen in figure 2. Therefore here absorber is expected to absorb as much solar radiation derived from sunlight.

Figure 2. The spectrum of solar radiation

More detail can be explained that the sun consists of a photon-photon, if it happen to solar cell surface material (absorber), will be absorbed, reflected or simply passed (see Figure 3), and only photons with certain energy level that will liberate electrons from atomic bonds, so that electrical current flows. Energy levels is called band-gap energy which is defined as the amount of energy required to discharge electrons out of its covalent bond so that there electric current flow. To free electron from its covalent bond, photon energy (hc/v) must be slightly larger or above than the band-gap energy. If the photon energy is too much of the energy band-gap, then the extra energy will be converted in the form of heat in a solar cell. Therefore it is important to the solar cell to regulate the materials used, namely by modifying the molecular structure of the semiconductor used.

solar photovoltaic3 300x118 Solar Photovoltaic

Figure 3. Radiative transition of solar photovoltaic

Of course, that the efficiency of solar cell can be high if the photons from sunlight to be absorbed that as much, then reduce reflection and increase recombination and conductivity of the material.

To be able to make that a photon is absorbed can be as much, then the absorber must have an energy band-gap with a wide range, making it possible to absorb sunlight so energy has a variety of these. One of the many materials being studied are known CuInSe2 is one of the direct semiconductor.

So many advantages of solar photovoltaic as described above was not a polemic and not just stop, saying there was a solar photovoltaic is true when the energy change process there is no pollution produced, but have we calculated how much pollution has been generated in the process manufacturing, small compared to the resulting efficiency. Now the challenge here is indeed how to increase efficiency, which would affect its economic value.

Collector Solar

July 08, 2009 By: Admin Category: Solar Accessories

Flat Collector

Flat collectors, and even concentrator is a tool used to collect solar radiation energy so that thermal energy produced can be used in more practical for a variety of processes. Flat solar collector consists of a transparent cover, absorber and insulator. Solar radiation that falls on the surface of the transparent material in the short wave will be forwarded by transparent material and then absorbed by absorber. Black color have an ability to absorb a larger radiation so that most of the sun radiation will be absorbed. Absorption of this radiation will create a high temperature absorber. Heat radiation emanated by absorber but in the form of long waves. Most of the transparent material has an opaque nature of long wave radiation and therefore part of the long wave radiation reflected back by this transparent material to the absorber. Some radiation is absorbed will be reflected back and the rest will experience the same process that is part reflected back to the absorber. Thus, the loss of heat due to radiation can be minimized by flat collector. In addition, the transparent cover also functions as a heat loss barrier carried by the air above the absorber to the environment.

Heat from the absorber is used through heat exchanger to the media of heat carrier. Media of heat carrier commonly used can be air or water. When using water as the media, absorber will conduct heat to the surface of the outside pipes. Then take heat conduction from the outside surface to the inside surface. With the process of convection, heat will move from the inside surface to the water that flows in the pipes, so the water temperature will increase. Water with a high temperature and then used in the other parts of the outside collectors flat. A similar process occurs when air is used as a medium of heat, but in this case the pipe is rarely used. The air above (or below) the absorber heated through convection due to direct contact with the absorber. High temperature air is then flowed out of collectors than used in processes that require hot air.

The performance of a solar collector will depend on the absorptivity characteristics of the absorber, transmissivity of transparent material, overall heat transfer coefficient of the insulator, the transparent material and the absorber.

Absorptivity is the portion of light that is absorbed by an object; transmissivity is the portion of light that is forwarded by an object, while the overall heat transfer coefficient is a power of heat transfer or the opposite of heat resistant.

What is a Home Solar Power System

Executive Summary about Home Solar Power by Junaid Mohammad

Installing a home solar power system in your residence is good for the environment.

Requirement

Home solar power systems can be installed on almost all homes except for a very small home which have less than 120 square feet of roof. In most cities you require building permit to install home solar power system to your building.

Working of the System

Home solar power system is installed on the roof where the solar energy is transformed into direct current (DC) power. At night this home solar power system will not work. Most of the home solar power systems are interconnected with you utility. Your utility would provide power as usual at night and during day when your electricity demand exceeds that produced by your home solar power system. In case of cloudy days the home solar power system generates less power.

Home Heating

There are other technologies which convert solar energy into heat but this home solar power system is not used for home heating.
Home solar power systems don’t have any moving parts and solar modules are also tough.

Home Solar Power Systems Generation
Executive Summary about Home Solar Power by Erick Valdes

Home solar power systems have come a long way in a short amount of time. Home solar power systems are designed to absorb energy from the rays of the sun. Today, there are three basic types of solar power for use in homes and businesses:

1. If you install an extensive solar system on your home, you can completely disengage yourself from your local power company’s clutches.

2. Augmentation systems. Most homes that use solar power use augmentation systems. These solar systems are meant to power just one particular aspect of a home’s energy needs, such as outside lights, water heaters, or appliances. The rest of the home’s energy is supplied by a traditional electrical system.

3. Backup systems. These are solar systems installed to keep a home’s power running in case of a blackout by the power company.

Home solar power systems have greatly improved in quality and performance over the past few decades. Solar power makes a home more energy efficient and is more friendly to the environment.

Solar Hot Water

May 20, 2009 By: Admin Category: Solar Heater

Solar Hot Water

Executive Summary about Solar Hot Water by Anna Williams

Solar hot water heating systems are a great way to effectively conserve energy and reduce your energy bill.

Important Facts about Solar Hot Water Systems

Solar water heaters can be used in any climate.
The fuel used to run a solar heater is sunshine.
A solar water heater can reduce your water heating bill by fifty to eighty percent.
Aside from reducing your energy bill right now, a solar heating system will protect you from future energy price increases.
When building a new home, or when refinancing, the economic aspect of this becomes even more interesting.
Using solar power to heat your water will significantly reduce your carbon footprint.
Solar heaters can be installed in combination with backup systems.

Types of Solar Hot Water Systems

There are two types of systems, “active solar water heating systems” and “passive solar water heating systems.” With a passive system, the water storage tank must therefore always be positioned above the solar water heater collector.

Active Solar Hot Water Systems

There is also the direct circulation system, where water is simply passed through solar heat collector and then routed to the water storage tank for use.

Passive Solar Hot Water Systems

Passive solar water heating systems are usually cheaper than “active solar water heating systems,” as they do not need controls or pumps to circulate the water.

If you live in a warm climate, a passive water heating system might be all you need. Essentially, solar water heating systems consist of a water storage tank and its solar collectors. The solar collectors are used to collect solar energy (which heats water), and the tanks store the heated water. 75% of the energy consumption of the average home is for hot water and heating. The most economical and effective way of using solar power is through the use of solar heating, and solar hot water heaters.

Homemade Solar Hot Water Heater – One of the Easiest Home Renewable Energy Systems You Could Make?
Executive Summary about Solar Hot Water by Denzil De Vries

Installing a solar hot water system is one of the easier projects to undertake if you are keen to create your own home made renewable energy systems.

The key to the solar hot water system is the solar collector. It is just a tank that has been modified to absorb thermal energy from the Sun. So it may be painted black on the external surfaces and have insulation on the internal surfaces to prevent heat loss.

The flat plate solar collector design uses the same principles but is designed to squeeze even more juice out of the Sun. The plate is painted black to again absorb solar radiation and heat. Along the plate is tubing that will hold water. The tubing exposes far more water to the heat than the ordinary old solar collector. This means more water is heated or made hotter.

Where you place your collector is vitally important but is dictated by two factors. It needs to get as much Sun as it can, so a south facing location in the home is best. But it also needs to move water to the boiler system in the home. So the nearer it is to the boiler the better. If the boiler is well located you could position the solar water collector above the boiler and let gravity move the water from boiler and back to collector based on the heat of the water.

A solar hot water system can be a simple as a solar water collector that has no moving parts or electricity to worry about and a connection to your boiler system.

Most people look into a solar hot water heater because they want to save money on their heating bills. With this in mind a solar hot water heater will help to reduce your bills by pre-heating water that goes into your traditional boiler.
