Solar Training

The New Economic Stimulus Plan will make solar installers one of, if not, the fastest growing job in the United States. In fact, the need for solar installers, trained, professional installers will increase exponentially in the coming year, and beyond beyond of the tremendous financial and social support for renewable energy. If you are going to cash in on this new, increased demand for green-collar workers, you will need the proper solar training.

Solar training is critical because solar energy is such a broad, deep and often misunderstood topic. Sadly, there is a ton of information available on solar energy on the internet and in books, but a lot of this information may be false, or outdated, and, the true information is scattered across hundreds, or thousands of sources that could take years to sift through and put together. This is where a good solar training course comes in.

Glitter-sized Solar Photovoltaics Produce Competitive Results

Adventures in microsolar supported by microelectronics and MEMS techniques

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.

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.

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 history of “Photovoltaic”

The history of “Photovoltaic” (PV) industrial development has been running about 50 years, and have been many studies done in the hope that one day could produce cheap solar cells and feasible compared with artificial electricity (hydro or nuclear) to solve the problem of availability of environment friendly electricity at all levels of this world.

In the late 19th century, solar electricity discovered by German physicist named Alexandre Edmond Becquerel accident where the sun rays fall on the solution of electro-chemical research materials, so the charge of electrons in the solution increases, there is no scientific explanation of the event. Not until the early 20th century, Albert Einstein called the discovery of this natural electrical event with “Photoelectric Effect”, which is the basic understanding of the “Photovoltaic Effect” (Albert Einstein got the Nobel Prize in Physics).

“Photoelectric Effect” comes from Einstein’s observations on a plate of metal release “photon” particles of light energy when exposed to sunlight. Photon continuously urged metal atoms and form a particle “Photon Energy”-is the wave of light energy.

Ultraviolet light waves, light that are high charged photon energy and short wavelength, while red light (infra-red) is low charged photon energy and long waves.

Then around the year 1930, research continued and related to discovery of the “Quantum Mechanics” concept, to create new technologies “solid-state”, which then the Bell Telephone Research Laboratories company create the first solid Solar Cell.

Year 1950 – 1960, technology of solar cell design and efficiency continued and applied to the spacecraft (photovoltaic energies). In 1970′s, the world encourage “renewable” alternative energy sources and environmentally friendly, then the PV is applied to the “low power warning systems” and “offshore buoys” (but the PV production could not be much because it is still “handmade”).

Just in 1980, the PV companies joined with government energy agencies in order to produce the PV cells in large numbers, so the price of solar cells can be more suppressed as low as possible.

Solar Residential Energy: What is it for?

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.

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.

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.

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.

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.

Wind Turbines

June 12, 2009 By: Admin Category: Wind Power

Wind Generators As Your Energy Source

Many people have started to install wind turbines, wishing to lower their bills for electricity, and in some way help make the environment safer while saving on non-renewable sources of energy. You need some knowledge before taking your various tools and purchasing your other needs for making a wind generator.

Whether you are installing a self-made or a commercial generator, you need to make sure you have the optimal location for it. You will need a place where trees and buildings are not obstructing the air flow.

If you happen to be living on a farm, obstacles probably aren’t a factor and the view of your neighbors is no concern. However when you live within the boundaries of a city, it can be a lot more difficult to install a wind generator.

The wind towers are so tall that they can be dangerous in storms and high winds, so this could impact the community. Consult not only your local authority but also your neighbors before putting one on your property. Of course you always need to consult for the county or city codes.

You have a few choices for the exact spot for your wind tower. The top of your house could be a great location or if you own enough land you can set the tower away from the house. In a small town, numerous wind generators can be installed in a common area for the whole community. So everyone can benefit from lower utility bills, and you do not have to worry about the towers getting blown over in a storm.

You could also look into other forms of renewable energy to run your house. If you have enough sun in your area, consider installing solar panels as a back up for your wind generator.

You can read more from Steven C. Jones on his blog about wind generators and renewable energy.

Solar Powered Lights – What Are the Benefits?

Executive Summary about Solar Powered Lights by Steve Sight

When you hear the term Solar Powered Lights, what do you think of? Chances are you think of outdoor lights that are powered by the sun. There are solar deck lights, solar post lights, solar pool lights, and solar fairy lights to name a few.

So, let’s get into the topic of the benefits of using solar powered lighting. Below you will find a list of the benefits of Solar Powered Lights and why they are important.

Benefits of Solar Powered Lighting

• Environmentally friendly- Uses natural resources (the sun) to create power. Clean and renewable.
• Very low maintenance.
• Low Cost. Energy from the sun is free.
• Easy to install. No wiring required
• Power outage will not affect your lighting.

Why should you choose Solar Powered Lights? Imagine if you did not have to pay such a high electric bill. With the use of Solar Powered Lights, it would be less.

Now think for a moment, if you were able to convert every electrically run item in your home to solar powered, how much money you could save. When dealing with Solar Powered Lights, the cost of the power is one very important incentive. However, money able to save is only one of the benefits.

Solar Powered Lights are environmentally friendly in comparison to the other more traditional sources of power. They do not pollute like coal, oil, or even nuclear power.

In conclusion, the use of Solar Powered Lights has several different benefits to one’s pocket book as well to the world around us.

Solar Powered Lights – Environmentally Friendly Illumination
Executive Summary about Solar Powered Lights by Armand Hadife

Solar powered lighting fixtures are useful in areas where there are no power supplies available and accented lighting is required.

Solar powered lights save the environment by not using any fossil fuels or releasing any of the pollutants that usual AC powered light sources emit.

The presence of other brighter lights around the solar lamps will also inhibit the lights from illuminating because the solar cells will detect this as day light energy.

Overall, solar powered lights are a great alternative to traditional outdoor lighting, especially if you want to save money on your energy bill.
