Revolutionary of photovoltaic applications in the architectural building has undergone rapid development, starting from ordinary technology to high technology in the 3rd generation, they are:
1. First generation (the 1980s)
PV panel module with an iron framework just mounted on the field of building flat roof with a brace (tracking).
2. Second generation (the 1990s)

Photovoltaic cells (PV) developed more integrated part of building materials: roof materials (tiles, shingles).
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 Wind Generator by Donald Whitehead
Renewable energy! There is renewable energy for homes for instance, it can range from solar power by use of solar panels, or wind power by use of wind generators both of which there are plans for. This article’s main focus is on wind generators and wind generator plans. A wind generator generates electrical power using the wind as it’s power source. Coupled with solar panels wind generators are the #1 pick for renewable energy for a large array of reasons. Wind generators, unlike many electrical projects, are very basic and can be assembled and installed by most home owners themselves. You can then purchase adequate solar panels as well as the right generator for your wind generation build.

A professor at MIT, Sheila Kennedy and her team at Kennedy and Violich Architecture (KVA) recently launched SOFT Rockers at MIT 150th-anniversary Festival of Art+Science+Technology (FAST) celebration.
SOFT Rockers is a sleek, solar-powered energy recharging station, disguised as a public furniture (teardrop lounge).
One of the things that a potential obstacle in the development of solar energy is limited space. All existing solar panels in a solar power generation should receive sunlight for at least the same intensity to produce electrical energy optimally. Therefore, all the solar panels should be installed in rows, which mean that also require large open space.
In addition, the performance of solar panels that are widely used today are still influenced by the temperature generated by the environment and direct sunlight. The higher the temperature, the performance of a solar panel will also decrease.
Imagine if your local bus stop allowed you to check your e-mail, share community information on a digital message board or monitor the local air quality? And perhaps best of all, what if it could tell you the exact location of that bus that you’re waiting for?
Rainbow Solar Inc. (RSI) has produced a transparent, photovoltaic glass window producing power 80-250 watts. Although this is not the “first solar window,” it seems that the RSI has taken a big step forward.

Solar power is harnessed and applied in ever more interesting and creative ways, and Renu personal power generation and storage system is certainly no exception. Device features a free-standing modular solar panels which, when filled, can be put into a number of extensions to take advantage of the energy collected, including an iPod dock and LED table lamp.
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.
Choosing the right science project for young people to do should include the concept of helping them become more involved in today’s important global issues. A science project on solar panels could be just the thing for them to gain a better understanding of how the energy crisis is affecting us and what they can do about it.
The world as we know it today has undergone drastic changes in the last few decades. Consider the past one hundred years of industry and the damaging effects this has played on the environment. Our lakes, oceans, and rivers are in a pitiable state. The very air that we breathe is infused with pollutants that make us sick. Natural disasters are becoming more occurent and destroy millions in property while killing hundreds of lives each year. The energy sources that have provided the power to fuel so-called economic and technological development and progress have taken their toll on our fragile environment. And the younger and future generations are the ones who are going to pay for the follies of the older generations who thoughtlessly abused our natural resources and the environment.
Teach Your Pupils This School Science Project
It has come to a point that the very survival of the human race is being questioned as being endangered in the coming years. The abuse of Mother Nature and her bounty has led to massive pollution throughout the globe. The biggest impact has been those of fossil fuels polluting, not only the atmosphere but, the water and other resources that maintain our survival. The mining of such fuels causes irreversible damage to the nearby environment.
They are a probable contributor to global warming, which threatens to melt the polar ice caps that could lead uncontrollable floods. The sulphur oxide emissions produced by fossil fuels cause harmful acid rain. Because fossil fuels cannot be recycled, they will eventually run out. The fact that our fossil fuel resources are fast depleting is a serious issue which we will have to face or else we can no longer have sufficient sources of energy to support human civilization.
High School Solar Panel Project
These all being said, you can imagine how educating the future generations of our world about energy efficiency can help in saving what remains of our energy sources and rebuilding the damage fossil fuels have done. The energy crises, the harmful consequences of fossil fuel use on the environment – our young people should be made aware as to how these are both significant issues that affect the very survival of the human race as we know it today.
Knowledge is a powerful weapon which can arm the future generations in their fight to rescue our ailing planet through resolving the issues on energy sources. Putting it into application makes it even more powerful. Showing the young ones the application of that knowledge is the best means to get their interest and win their support.
The Theory and Pracitical on a DIY Solar Panel Project
Imagine the future effects on the energy crises if pupils and students in all learning establishments were to undertake a school science project that included theory and the building of a solar panel. Solar panels harnessing the energy from sun rays are very appropriate to demonstrate to the youth the alternative energy solutions that are available. Doing the project by themselves will help them realize just how efficient solar power is. Harnessing power from the sun is a concept that young people of today should be familiar with. Let them have a hands-on project on alternative energy sources such as this one and this will help everyone benefit from the knowledge that the energy and environmental crises can be solved with modern scientific solutions.
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.
Executive Summary about Home Solar Panels by Valt Jones
Home solar panels are the desirable solution for anyone willing to substitute the polluting energy created by fuel-supplied energy plants with green and renewable source of energy. Home solar panels can either turn sunlight into electricity or hot water.
Home solar panels are smaller and inexpensive nowadays, while the rewards have grown exceedingly. Installation of home solar energy systems has become its own licensed specialty performed by licensed home solar contractors. These solar panels are the most consistent source of harvesting energy for residential solar power generation, doing better than the solar cells of previous decades. Marine and RV solar panels and specialty items, such as Powerflex flexible and portable solar panels, are also available.
You will require less home solar panels to collect the necessary energy if the sun is shining often. Home solar panels are generally designed for high voltage grid-connected systems, although they can be used for battery-based systems too. Solar panels that use single crystalline solar cells offer among the record efficiencies obtainable on today’s commercial market.

Executive Summary about Solar Roof By Dan A Swanson
The advancements in solar technology has helped in creating more efficient and light weight solar cells that make solar roof panels a more practical choice for the ordinary households. Solar cells of the solar roof panels are able to convert sunlight into solar energy which can be used for providing electrical energy to your home.
These solar shingles or solar roof panels are meant to replace the regular shingles of your home, thus providing a waterproof coverage to your home and also generating electrical power as an added advantage. As far as their installation is concerned, a solar roof panel is easiest to install.
Advanced solar technology is able to produce solar cells that can produce 20% efficiency, as compared to 7-10% produced by older cells.
The different kinds of solar roof panels are the traditional types, advanced types and compact types while the best ones are light weight panels which are less expensive, smaller in size and still capture sufficient amount of energy every day.
Benefits of a Solar Roof Panel
Executive Summary about Solar Roof By Eben Jaimes
With the high cost of living, more and more people are turning to renewable energy generation for their homes. One of the main sources of renewable energy, that seems to be the most popular, is having a solar roof panel installed on your home.
Having a solar roof panel is an extremely efficient supplier of energy. This means that the utility companies have to pay you. You will be happy to know that by generating electricity from a solar roof panel, you will help reduce greenhouse gas emission. A simple 3kW solar system reduces carbon dioxide emissions very close to the amount of carbon dioxide emissions given off by a passenger car traveling 8,000 miles per year.
Also, with a solar roof panel, you can think long term. Almost all of the satellites that orbit the earth are powered by solar energy. As a special benefit, a solar roof panel system is eligible for a $2,000 federal tax credit. If you happen to live in California, the California Solar Initiative (CSI), offers an up-front rebate.

Executive Summary about Solar Electric by Klaus H Hemsath
Promotion of solar power generation is booming. Why are solar farms built when financial data clearly show that solar power is still the most expensive electricity generation technology available?
Solar power plant developers and marketers obviously know that they need to lower costs. Cost reduction is, however, expensive and takes time. There are two major technologies for solar energy conversion. Electricity production with steam is a very mature technology. The other technology is the direct, photovoltaic conversion of sunlight into electricity. This technology will most likely become the dominant solar electric power generating technology – eventually. The concentrated sunshine creates very high surface temperatures on the solar panel. To save solar panel area and make the solar panel price competitive, one must cool the surface of the solar panel very efficiently to prevent it from melting and destruction.
Present production costs for generating electricity with solar panels are hovering around $0.50 per kWh. Right now, solar power does not yet make economical sense.
None of the available technologies using renewable energy can compete with the cost of electricity generation from coal.
The technologies for generating electricity with solar power, wind power, marine power, and geothermal power are very well understood. At present, a respectable number of windmill farms and solar panel farms are being installed. Solar power does not make economical sense, yet. A random sampling of recent announcements of solar farm installations reveals that system installation costs are in the $3000 to $7500 per kW installed capacity. These plant costs loosely translate into a cost of producing electric power at $0.30 to $0.60 per kWh. This very unfavorably compares to the cost of electricity generation by any other technology.
As long as solar power constitutes only a very small fraction of overall electric power generation, the additional costs of storing intermittently produced electric power are not yet of concern. If the US is going to depend significantly on the intermittent production of electricity from solar power and wind power, it must begin to develop storage technologies for huge amounts of electric energy. Intermittent, renewable energies and electric energy storage are inseparable.
The Solar Electric Panel – An Inexpensive Way to Generate Electricity
Executive Summary about Solar Electric by Dan A Swanson
The solar electric panels, generally called solar photovoltaic panels, are made of a set of treated silicon cells arranged in a series array. They produce electricity on being exposed to the sunlight. A small solar electric panel will lessen the energy bills considerably, while a big solar panel will in fact budge the meter backwards. The contemporary solar electric panels are simple to install and are modular. The solar electric panels transform the sunlight to DC (direct current) electricity. Buy any of these solar electric panels according to your requirements.
Solar electric panels are the perfect answer to our increasing electricity bills and ever increasing reliance on depleting conventional energy resources. Make a one time investment in solar panels and generate free electricity for years to come. Solar electric panels are the need of the hour.
