One of the answers to the energy crisis is to apply solar power. Solar power is the energy source of the most powerful and freely available to us now. That is why production of solar energy kits more abundant.
Solar energy kits is slowly taking place in most of the different houses in the world. Householders feel easy, convenient and effective to obtain energy from the sunlight.
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.

Executive Summary about Solar Light by Jerome Sturgeleski
We all have access to a free, bright and renewable source of light – the sun. A great way to utilize it after dark is with solar lights. The lights are powered by light emitting diodes (LEDS) which rival hard-wired lights. Solar light have several advantage over hard-wired lights some of which:
Adventures in microsolar supported by microelectronics and MEMS techniques
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.
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.
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.
(in Olmedilla de Alarcón, Spain, 60 MW) Finished in September 2008. This power plant uses 162,000 average photovoltaic solar panel to deliver 60 MW of electricity on a sunny day. The whole factory was completed in 15 months at a cost of about 530 million U.S. dollars current exchange rate. Olmedilla built with conventional solar panels, which are made with silicon and tend to heavy and expensive.

Solar technologies is now highly developed, with some progress is being developed to be used every day.
Below 10 Solar Technologies to note:
Initial concept of light tubes developed by the ancient Egyptians, namely by direct use of natural light tubes with reflective material. This is the concept of the oldest and most widespread type of natural lighting of interior space.
Light tubes are also known as “tubular skylight”, “SunScope” or “Tubular Daylighting Device” allow natural light into the darkened interior room of buildings and houses. The people enjoy the natural lighting provided by skylights. However, skylights are often not evenly distribute the light, is the loss of a significant source of energy, and UV light can cause damage to the carpet and furniture. Light tubes, on the other hand, using the sun for lighting interiors without the shortcomings associated with conventional skylights. To prevent the danger of ultraviolet radiation (UV) from the carpet and furniture fading, UV inhibitors formed a dome roof on most models. Another bonus when choosing light tubes is that they provide far more heat slightly, as did the standard skylights. Because of the lack of acceptance of this heat, tubular skylights to save money on air conditioning bills during hot months.
Taking advantage of free sunlight as much as possible, the pipe hole collect sunlight from the roof dome light collector consists of an acrylic lens, bounce it to the bottom of a tube with a highly reflective interior coating, to pull the lens cap is similar to conventional recessed lighting equipment and diffuse sun light evenly throughout the interior rooms. The tube can be bent and adapted to drive around the garret or ceiling obstructions with small loss of light transmitting and can often be installed in less than three hours. Not like the ceiling of need roof to the ceiling of the timber-framed shaft and covered with drywall or wood panels, and the need for structural modifications, so installation is simple and relatively inexpensive.
Roof mounted dome made of high quality acrylic resin specially formulated to enhance the impact strength, chemical, weather resistance and high clarity.
Light tubes can be installed on almost all types of roof materials, including wood and asphalt shingles, concrete and ceramics, and metals. Thanks to a highly reflective coating on the rod, the tube can work efficiently from sunrise to sunset.
Most of the producers of glass tubular solar roof offers a 10-year warranty against defects in materials and post-installation cracks or discoloration. Tubes solar installation contractors generally offer a 2-3 year warranty for the installation of weatherproofing and storm protection.
The average size of the tubular skylight ranges between 10 and 21 inches (254 and 533 mm), diameter, which effectively light of 100-600 square feet (30,48-182,88 meters), interior space. The main factor in choosing a general measure of the distance between the roof rafters and / or ceiling beams.
Prices range from around $ 171.00 to $ 423.00. Installing a solar tube usually cost between $ 500 and $ 800. Both depend on the size of tubes and features installed.
Light tube options include:
Energy-efficient light tubes is an important part of the house and environmentally friendly buildings. Natural light effects on your physical, emotional and psychological well known as the rooms benefit from natural sunlight free will positively impact our environment for future generations. They are environmentally-friendly way to naturally brighten every room, a smart alternative to skylights and artificial lighting.
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 energy: this term basically does not cause a stirring in the mind as the explanation that comes at hand is indeed too simple. Everyone knows what is meant by solar energy, and that is, the energy that comes from the sun. In its most basic sense, solar energy and other solar residential equipment are nonetheless environment-friendly and not risky at all. But then you need not become one fine environmentalist first before you will be able to come across with whatever advantageous benefit solar residential energy has.
Why is the solar residential energy said to be environment-friendly? What are its general benefits? Practically speaking, when solar residential energy is used, the electrical bills tremendously go down as compared to the other type of residential energy available for all people. Why would you pay for such expensive bills when all you need to do is to employ solar residential energy?
Another major advantage of the solar residential energy is the absence of the very complicated and dangerous wiring. Solar energy lights in the garden path or any other solar energy-powered items used in your residential are ready to be installed less the wiring to be dealt with. In reality, these solar light bulbs are equipped with darkness sensors so they need not be turned on to give off light and they need not be turned off as well when they are no longer needed.
As a sort of simple explanation, the solar light bulbs will simply have to be purchased, taken out of the boxes, installed, and then presto! You just have to situate them where you want them to be and never worry about them ever again.
A List of the Benefits of Solar Residential Energy
Why is the solar residential energy equally beneficial? Why is it more recommended for use? Here are some of its benefits which are truly worth the attention to be graced by anyone:
Solar residential energy is environmentally friendly. As mentioned a while ago, solar residential energy will not harm the environmental features. It is specifically clean and renewable as well. More so, it does not cause pollution just like what the rest of the traditional electrical forms do.
Solar residential energy systems need the least maintenance. They are not fuel-powered so no need to buy the refills.
Solar residential energy makes you save a lot of money. The energy that is derived from the sun can be accessed for free as you make use of solar lights, solar panels, and the likes. The federal government most of the time gives out financial incentives. You don’t get affected by the rise of the fuel rates since you are using solar residential energy.
Making use of the solar residential energy makes you entirely independent from the foreign and centralized energy sources. Power outages will not likely affect you in any manner.
Most of the solar energy items are very easy to install thus lessening the complicated work of the wiring systems.
Some Common Disadvantages of the Solar Residential Energy
Of course the disadvantages will not be taken aside. Here are some of the most common disadvantages of the solar residential energy:
The employment of a solar residential energy can be expensive at first. But as time passes by, it becomes light to the pocket.
The strength of the solar residential energy will relatively depend on the location of your residence in relation with its facing to the sun. Also, the area of your residence is another point to consider. You will need large areas to install the solar panels.
The Various Solar Energy Items
There are lots of solar energy devices that you may opt to buy. Included are the solar flashlights, solar heaters, car ventilators, solar video cameras, solar radios, solar pool purifier, solar mosquito inhibitor, solar lighting, and solar fountain pumps.
What You Must Do
Back in the earlier years, solar energy powered devices were very costly that very few homeowners made use of the solar residential energy. But these days, small volumes of solar energy devices are put up for sale therefore making it affordable for all. If you don’t have enough money to fund these items you can always start small.
Many people, especially those who are beginners in solar technology may wonder how solar panels work. But first, what is the home solar panels? This is a solar-powered gadget that collect and use the energy from the sun through its rays and convert it into power.
Some people use solar panels home gadgets to act as an alternative source of energy for their small household, effectively complements the consumption of electricity from local utilities.
There are still homeowners who invest in residential solar panels are fully able to provide power to the house, run all appliances, water heaters and swimming pool. However, the cost is very expensive if you intend to own and install your own home solar panels that will work as the only source of daily strength. A solar panel unit actually has a very high price from a few thousand dollars.
How solar panels work can be answered simply. He has a photovoltaic cell in a panel that primarily works by collecting energy from sunlight that falls on them, then solar energy is converted into electrical energy for use at home.
You may very well consider this gadget as an investment, because you need to shell out large enough amount of money to buy and install them as your resource. It is a serious investment even if you only need to spend the money early, the amount needed is really great. After purchase you do not have to worry about this as the sun runs his own gadgets, making endless supply of electricity to your residence with the help, of course, the sun.
Many supporters of a clean environment and recommended the use of green house solar panels, if only because the energy that collects and converts power from the sun. Therefore, the power generated is clean and not harmful to the environment of the world. Likewise, you do not have to worry about running out of the sun’s energy for endless supply. Solar energy is a clean renewable energy, and is considered the best alternative energy is there.
Did you know you can cook entire meals without any electricity or gas? It’s true. If you have access to the sun then you can cook with it.
Cooking with the power of the sun is commonly referred to as solar cooking, and you don’t need expensive gadgets or equipment to do this successfully either. Solar cooking requires sunlight of course, a bit of time, a few everyday items, and a willingness to experiment.
In the most basic form, solar cooking can be done easily as long as you have decently strong sunlight for a few hours. The stronger your sunlight is of course, the easier your solar cooking will be. In the desert southwestern areas of the United States for example, you can literally just lay food out in direct sunlight in the summer and it will cook quickly for you. We’re going to look at a little more than the basics here though.
There are two primary ways to cook food with solar power. One is to use what’s known as a parabolic cooker, and the other is to simply use reflecters.
A parabolic cooker is actually just anything you have on hand which has a slighly bowled, or parabolic shape to it. Round satellite dishes are excellent examples of this type of inward curved surface. The slight curve of a surface like this will allow you to concentrate the natural heat of the sun onto the food you’re cooking.
Parabolic cookers can be made with simple cardboard, or any slightly concaved material such as an old (small) sattelite dish, a small wok, or even a bent and curved trash can or barbecue lid. Using old materials for this is great because it allows you to recycle and it doesn’t usually cost a thing.
Most people choose to make their first solar oven with cardboard because it’s readily available, easy to work with, and free.
The best parabolic solar cooker will have slanted sides though, not upright ones. A slant of about 60 degrees outwards is ideal. Once you find the object you plan to use for your solar cooking, then you simply cover it with tin foil, mylar, or mirrors. Mirrors can actually be dangerous because too much heat is generated, so it’s best to start with aluminum foil. Cover your concaved object with the foil so that the shiny side is facing out. This will capture more of the sunlight shining down on your solar cooking, and help focus it onto your food.
Simple reflector style solar cookers are another popular option, and in many cases you don’t even have to put things together to make this work. With this style of solar cooking, you simply put a pot or pan out into direct sunlight and surround it on three sides with reflective material to help direct the solar heat to your food.
With either solar cooking design though, you’ll want to use either glass or dark metal cooking pots and pans. Dark metal helps attract and absorb the natural solar heat from the sun, and glass allow that solar heat to pass through easily yet stay trapped inside for cooking.
Depending upon the strength of the sunlight you have available and the solar cooker design you’re using, it can take anywhere from one to three hours to fully cook common meals for three to five people.
Of course you can also use regular solar panels or a solar power generator kit to power a more conventional energy efficient stove or oven when the sun isn’t strong enough to use your solar cooker, or if you prefer to cook foods in a more traditional manner.
Solar panels are generally made from crystalline or amorphous silicon. Amorphous means that the solar cells does not have a crystal structure. When you see a lot of solar panels, you will notice a mosaic pattern. This mosaic is different silicon crystals that grow together in different orientations.
amorphous silicon solar
Amorphous type silicon solar panel do not have a crystal structure. Amorphous silicon is as a glass or obsidian. The silicon atoms are all frozen together in a random way. However, in crystalline type silicon solar panels, the silicon forms a lattice or regular repeating crystal structure.
Excess crystalline type solar cells is that they are generally more efficient. However, the crystals need time to grow and therefore more expensive to produce.
Amorphous silicon panels cheaper to produce, because no crystal structure that needs time to form. However, the amorphous solar panel is less efficient.
Some solar panel manufacturers such as Sanyo has been producing solar panels that use a combination of amorphous and crystalline silicon for maximum effect. High efficiency crystalline silicon can be used to capture most of the energy, but the various layers of amorphous silicon is added to capture what is left.
So, what amorphous construction silicon panels? They are solar panels made from a non-crystalline variety of silicon.
Note: When purchasing crystalline or amorphous silicon panel it is important to consider the cost with efficiency. A crystalline silicon panel may be very efficient, but cost can be overcome benefits. Amorphous panel less efficient, but they are also cheaper. So, there is always a balance between costs and benefits.

Executive Summary about Solar Technology by Philip Richards
In the business of solar energy, the U.S. has not been the biggest buyer of solar power. While the U.S. does quite well exporting solar panels and solar technology, there are many Americans who still find the cost of panels very prohibitive. As the price of solar energy decreases, Europe has had a much higher demand for solar power than anywhere else in the world. Many European universities and campuses have rebuilt their dorms to run off solar energy. Most water heaters in Europe are solar-powered, even if the home doesn’t have a full solar panel system.
In Europe, it’s not just small residential power systems that are leading the way in solar energy dependence. Specifically, Italy, Greece and the Czech Republic are the newest customers of solar power systems. These countries have begun to purchase so much solar energy that their borders have seen changes in tariffs for solar panels. Japan, who’s also been at the forefront of solar panel imports, has picked up solar panel buying as the cost of gas and electricity rises. There are entire neighborhoods in Japan outfitted with residential solar power panels. For example, the neighborhood of Iwaki New Town has about 46 homes outfitted with full private solar power panels. Japan also uses solar energy in surprising places. Japan is the only country to power most of its vending machines with solar energy. Sharp, one of the largest solar panel producing companies in Japan estimates that by 2010, Japan will produce 4.8 million kWh of solar energy.
The Race For New Solar Technology Is On
Executive Summary about Solar Technology by Winifred Churchill
Companies around the world are beginning to seriously consider the POWER of solar power.
One criticism of solar energy is that it cannot be relied upon for a steady supply of energy, but there are projects underway which are addressing that issue. In short, solar technology is going the way of the computer industry or cell phones. Now you get the same functionality available in personal computers on tiny cell phones. The new silicon cells for solar panels may bring a similar revolution to solar power making it a reliable, clean source of energy.
