Here’s a finding reported on Sunday in the journal Nature Materials, which offers a new way to process conventional silicon by slicing the brittle wafers into ultrathin bits and carefully transferring them onto a flexible surface.

US researchers have found a way to make efficient silicon-based solar cells that are flexible enough to be rolled around a pencil and transparent enough to be used to tint windows on buildings or cars.

“We can make it thin enough that we can put it on plastic to make a rollable system. You can make it gray in the form of a film that could be added to architectural glass,” said John Rogers of the University of Illinois.

It opens up spaces on the fronts of buildings as opportunities for solar energy,” Rogers said. Solar cells, which convert solar energy into electricity, are in high demand because of higher oil prices and concerns over climate change.

The new technology could be used on car windows, generating enough electricity to power the GPS or air conditioning.

Many companies, including Japanese consumer electronics maker Sharp Corp and Germany’s Q-Cells are making thin-film solar cells, but they typically are less efficient at converting solar energy into electricity than conventional cells.

Rogers said his technology uses conventional single crystal silicon. “It’s robust. It’s highly efficient. But in its current form, it’s rigid and fragile,” he said.

Rogers’ team uses a special etching method that slices chips off the surface of a bulk silicon wafer. The sliced chips are 10 to 100 times thinner than the wafer, and the size can be adapted to the application.

Once sliced, a device picks up the bits of silicon chips “like a rubber stamp” and transfers them to a new surface material, Rogers said. “These silicon solar cells become like a solid ink pad for that rubber stamp. The surface of the wafers after we’ve done this slicing become almost like an inking pad,” he said. “We just print them down onto a target surface.”

The final step is to electrically connect these cells to get power out of them, he said. Adding flexibility to the material would make the cells far easier to transport. Rogers envisions the material being “rolled up like a carpet and thrown on the truck.”

“The work could create new ways to use silicon in photovoltaics – as ‘tinting’ films in architectural or automotive glass (like sunroofs); as large area ‘rollable’ sheets; or as lightweight ’solar skins’ for integration onto structural surfaces on buildings or even aircraft,” says Rogers.

However, if your intention is to enjoy the freedom of the wide open spaces where there is no hook-up, and going off the beaten track is what you think is going to be more fun, then you could consider having RV solar power systems which will come in very handy if you are in a quiet location, or by the stream, or out there in the back of beyond. Having RV solar power systems in such circumstances would make it altogether unnecessary to look for another campground or other spot with full hook-up.

Thus, RV solar power systems are really practical for those who want to go to places where there is no hook-up as it provides a practical and effective solution to their energy needs and allows for going to places off the usual track and can make for a more comfortable outing even in the remotest of places.

It is also not difficult to operate RV solar power systems and the same is the case when charging the batteries with the help of solar power, though not all RV solar power systems are the same and so you must plan for the type that suits you the best. It is thus necessary to determine the energy requirements that will suit your RV needs after which you must go out and buy as also install the solar panels, inverters and batteries that should then be able to output sufficient energy for all of your needs.

If you need help with determining the amount of energy you will need for your excursions, you can always go online and search the Internet where there are many websites that will provide you guidance on this matter and which will also explain the components required to generate that much energy. And, to meet different energy requirements, there are RV solar power systems available in all sizes that will fit different needs.

Using solar energy is a great way to save on utility bills (and also to help save the planet).

But most people’s good intentions are nipped at the bud when they discover the cost of converting their home to solar power.

When we last did our check around end-December 2007, very few homes in America run “entirely” on solar/hydro/wind power. But the future is bright with reducing solar power cost trends.

Solar power cost trends have gone down since the 1970’s an continue to go down every year as more and more companies are determined to lead the way in the relatively new-old field of solar power.

The standard to determine solar power cost trends is called the cost per watt.  In 1982, the cost per watt was $27.  In 2003, this has dropped to $4.  This is expected to drop even further.

Solar power cost trends for the initial installation are also going down.  Most states now give tax breaks or tax refunds to any homeowner converting to solar energy.

Many US states and European countries have other green incentives, especially in sunshine-heavy California.  But even the temperate New York also has tempting green incentives.  Because of the ever-fluctuating world of tax and banking laws, be sure to check with your Department of Energy and your local tax accountant to see what you can get back.

Making the huge commitment to converting your entire home to renewable energy is a huge leap that you may not be able to soundly make.

But there are still other ways where you can choose green energy over non-renewable energy sources.  Solar power cost trends have gone down for common small items such as watches, calculators and cell phone chargers.

You can even get the air pump or water heater for your pool off of the utility grid and hooked up to solar power for only a couple of hundred dollars (US).

The main reason major companies have not embraced solar power is it’s comparative inefficiency with non-renewable energy sources.

You need a lot of room for solar power panels to generate a significant amount of solar power energy.  However, not only the cost of photovoltaic cells have gone down, so has their size.  I

n many ways, solar power cost trends are mimicking the personal computer cost trends.

An RV solar panel is an electrical system that uses light from the sun to charge your RV batteries and which is capable of not only running the basics in the RV such as lighting, but also all of your other RV appliances as well.

One of the best features of these RV solar panel systems is that you are free to go almost anywhere you want in terms of traveling without having to worry about finding a source of power for the vehicle and the appliances inside.

There are hundreds of companies around the world that offer these RV solar panels, but you want to choose one that is going to offer you the best quality solar panels for the best possible price.

• They feature a unique design, especially the lightweight construction and the tough nylon fabric covering which allows the unit to be folded to a convenient book size that makes for very easy storage and transport.

Mr. Solar

• If you are looking for an RV solar panel system then Mr. Solar is another company you are definitely going to want to consider.
• They feature the most high efficiency brand name solar panel systems and kits at very competitive prices, including names such as Sharp, Sanyo, Photowatt, Mitsubishi, BP, GE, and more.
• For people who love to travel and who are always on the go, an RV solar panel system is really terrific because it makes your traveling experiences easier and more convenient.
• You can travel to places you never imagined before and still have the source of energy that you require for running the vehicle and the necessary appliances.

Although commercial manufacturing of solar panels is done in a strict quality controlled environment, for experimental purposes you can build your own solar panel to see how the sun’s energy can be converted to electricity.

Okay, lets get started:

• While the most efficient panels are made with silicon, you can build your own solar panel by using cuprous oxide, a material known to cause light to be turned into electricity.
• You probably cannot go into a store an buy cuprous oxide but you can duplicate it on a thin sheet of copper.

  You will need about one square foot of thin copper plate, two alligator clips and short leads of wire, a wide mouth glass jar, tap water and salt.

• The use of a voltmeter, capable of measuring extremely small amount of electricity will be needed to see the end result.
• To build your own solar panel you will need an electric stove or hot plate on which to heat the copper sheeting.
• Place the copper sheet on the burner and turn it on high and let it sit there for about 30 minutes.
• As it heats, you see the plate turn colors and the heat will show the outline of the heating coil underneath the plate.
• As it gets hotter it will begin to turn dark until the entire sheet has a black coating.
• After the entire sheet is black, turn off the burner and let it sit to cool for about 20 minutes.
• As it cools the black cuprous oxide coating will begin to pop off the sheet, leaving a thins coating of red on the copper.
• This red coating is needed to build your own solar panel, and while the majority of the black can be rinsed off under running water, it should not be brushed clean.

Salt Water Helps Produce The Electricity

Using the alligator clips, connect the copper sheet to one the top of one side of the glass jar. Attach another clean copper sheet to the other side of the jar. Mix about two tablespoons of salt into hot tap water, making sure it dissolves and then pour it into the jar. Be careful the water does not get on the alligator clips. The two copper sheets should be under water with about one inch left exposed at the top of the car to build your own solar panel.

Carefully place the entire contraption in the sunlight, either in front of a window or carry it outside and expose it to the sun. Using the voltmeter connect the leads to the two alligator and you can see the meter indicate the small amount of power being generated by sunlight, proving you were able to build your own solar panel.

Portable Solar Panel For Mobile Convenience

Whether you have purchased or built your own solar power generator, you are most likely going to be interested in knowing where you can go to find a portable solar panel (also called flexible solar panel by some) — so that if you need to do any traveling you can do so and will still be able to run your electricity needs off of solar energy.

A portable solar panel is especially ideal for people who travel a lot, for instance in a recreational vehicle, because not only can you power the entire vehicle with the portable solar panel but the appliances inside as well.

The Silicon Solar Inc. is one of the companies you can check out for portable solar panels. Besides this they also offer a variety of other solar energy related products including solar garden lights, specialty solar lights, solar spot and flag lighting, solar battery chargers, solar power accessories, solar books, and more. They offer resilient, durable and affordable portable solar panels for a wide spectrum of applications, and their photovoltaic systems are specifically designed to be able to withstand the most extreme temperatures, high winds, and even marine conditions, so that you are ensured the best quality solar panels with maximum longevity.

The Outfitter Satellite Company is another ideal option available to you here, and they offer three different sizes of portable solar panels. This makes it convenient for you because you can choose the proper sized solar panel depending on your particular needs, and the smallest is a Solar Port panel, which is built into a belly pack with a built-in rechargeable battery.

Portable or Flexible Solar Panels are a relatively new solar technology development, and we can be sure they will continue to get more improved every year - because the demand is great and so companies are keen to improve the product. Regardless of where you actually go to purchase your portable solar panel or what you are using it for, the best thing is that you are doing what you can to take care of the environment by using a source of energy that is not emitting harmful gases and polluting the air.

By the way, if you are serious about using Portable or Flexible Solar Panels in a big way - like across your farm or building complex (if you are in real-estate) - then you can contact us and we can suggest some good sources for importing these solar panels. The savings will be clearly visible if your budget is a few thousands or more.

Solar energy is the mother of all renewable energies on earth. It is free, needs no fuel and produces no waste or pollution and so it is great for the environment, especially compared to its counterparts. Solar energy is radian energy that is produced by the sun and then converted into usable energy.

People have been harnessing this power for centuries now but never has it been more popular than in today’s day and age, especially when environmental matters such as global warming are so imperative and in our faces.

There are many different practical uses for this solar energy, one in particular being for a solar energy water heater. After all solar energy can be utilized as a form of heat such as solar water heating and these systems are commonly referred to as Solar Domestic Hot Water systems.

Advantages and Benefits

1. By using a solar energy water heater you will be benefiting in more ways than one. A solar energy water heater greatly reduces the amount of fuel that you need to heat the water and this applies regardless of which specific design is used for the solar energy water heater, of which there are three main components it will consist of, including a solar collector which will convert the solar radiation into usable heat, a heat exchanger which transfers the heat from the solar collector into the potable water, and a storage tank to actually store the solar heated water.
2. A solar energy water heater is designed to be incredibly durable and versatile, and will last you many years with little to even no maintenance at all. They can reduce your water heating energy needs by up to one-half and because solar energy is renewable and clean, you know that you are doing what you can to protect the environment by switching from more conventional and harmful sources of energy.

Note: Before you make the switch, even though you are aware of the plentiful benefits, please make sure that you are as informed as possible so that you can really make the most of your solar water heater and any other solar powered products and devices that you decide to begin using.

The goal of this company is to do much more than just supply consumers with solar energy grants. They want to accelerate the use of renewable energy in as many ways as they can, namely by providing valuable and credible information, insightful policy analysis and innovative strategies.

They support the advancement of renewable energy technology through policy research and other means and are constantly seeking to define growth strategies for renewable energies that respond to competitive energy markets and environmental needs.

Infinite Power

Infinite Power is another organization that is working to bring awareness and provide information on solar energy and part of the way they do this is by offering solar energy grants. They offer a variety of programs that are designed to accelerate the acceptance of renewable energy resources and technologies by increasing public awareness, demonstrating new technologies and by developing the infrastructure that is necessary in order to increase the use of these new technologies in existing programs.

There are many different ways in which you can incorporate the use of solar energy in your life, and it is important that you take this matter very seriously, especially in today’s day and age when environmental problems such as global warming have become so significant and worrisome.

By using solar energy to replace the more conventional sources of energy that you use so often, you will be doing a large part in terms of protecting the environment and protecting it for the future. Solar energy grants can be used to help bring even more awareness to this issue, which is why they are so important.

Flow Control System

One of the most important aspects to solar panel efficiency is a flow control system. This will save a ton of wear and tear on your panels and will help a great deal with solar panel efficiency overall, especially since older panel systems tend to take a long time to heat up. A proper control flow system will work to attack the efficiency problem caused by older panels by reducing the amount of water that must be heated to capture the energy.

Buying Guide

Whenever you are buying solar water heating panel or any other sort of solar powered device or product you also need to consider solar panel efficiency. Remember that the longer the panel is able to provide useful energy the more attractive it is going to be for you to install a solar water heating system that, if carefully and properly constructed, should last for at least twenty years if not more.

If you are going to buy solar panels then you want to make sure that you compare by them dollars per watt, and also you will be benefiting greatly if you buy used solar panels. A solar energy system will typically cost you a few thousand dollars, depending of course on how large a system you get and what specifications you want included.

If you have a larger home and are looking to have solar power run the home entirely then you are going to want to prepare yourself for a large initial cost, although you will end up making your money back and more farther on down the road once you have been using the system for a while.

Make sure that any system you purchase is going to be easy to install and use, as you do not want to have problems every time you go to do anything with it. Typically there is little to no maintenance involved with solar powered devices, as you just have to sit them out in the sun and they do everything on their own.

Solar energy is more popular today than it has ever been before and you can produce solar energy for your own home with the right solar panel kit. Because of the popularity of this cheap, renewable resource, there are a number of different companies around the world that offer these solar panel kits, and for a reasonable price as well.

Remember that when you are shopping for solar panel kits you want to check out the different ratings, because it is important to know how well a kit is going to perform before you buy it.

Also know that for most solar panel kits the STC or Standard Test Conditions will be higher than the PV or PV USA Test Conditions, as the STC is a watt-rating used by manufacturers while the PTC rating is based on a 1000 watt/m2 solar irradiance.

Spheral Solar

The Spheral Solar Company sells solar panel kits, and a variety of them at that. They understand that solar panels are the heart of any solar power system and this is why they offer only the highest quality solar panels on the market. Whether you need a smaller solar panel for a battery charger or minor appliance or a large solar panel to power an RV or lighting system, they have everything you need.
