The future is huge for tiny technology. Miniaturization is, perhaps ironically, a huge deal. I mean, without it we wouldn't have had the personal computer revolution and we wouldn't have this world we live in now, where we have smartphones and tablets and other devices just as powerful as a computer, that can fit in the palm of your hand. But even these gadgets are gargantuan compared to nanotechnology! See, a nanometer is just one billionth of a meter. And that's kind of hard to imagine, so let me put it to you this way.
Your typical sheet of paper is about one hundred thousand nanometers thick. And at this scale, individual elements are so small you can't even see them with a light microscope. Now as we learn more about how materials behave on the nanoscale, we have more potential applications to use that knowledge practically. I'm talking about how nanotech could help solar panel technology. And fortunately, at a recent meeting of the American Association for the Advancement of Science, or AAAS, they had a panel on just this very subject. Now if you know anything about solar panels you know they have some drawbacks. For example,.
Efficiency they max out at around twenty percent in the field under ideal conditions. They're also rigid, so you can't just put them anywhere you like. And they tend to be expensive because manufacturing them is complicated. But scientists hope that nanotechnology can help address all three of these challenges. Now with efficiency they're looking to nature specifically, moth eyes. You see, moths have these little tiny structures in their eyes that help reflect light back into the eye and it does two things it lets them see better in the dark, and it cuts down.
On reflection so predators can't spot them as easily. With solar panels it could actually make them more efficient by reflecting more of the sun's light into the panel so you lose less in reflection. And when we're talking about flexibility, well nanomaterials are really, really small, and there is the potential to create solar panels that are just a few sheets of molecules thick. They could be as flexible as a sheet of paper, and with that kind of flexibility you could put those pretty much anywhere you wanted to.
And as for price, well, that's the big one. And in the short term I don't think it's going to turn around. But scientists are cautiously optimistic that nanotechnology will let us use new processes, like printing solar panels directly onto a substrate using just a specialized printer. That would actually be less complicated and expensive than traditional manufacturing methods. Now at that meeting of the AAAS, a Dr. Wolfgang Porod gave a talk about Nanoantenna Thermocouples for Energy Harvesting. Which I admit sounds like technobabble straight out of a Star Trek episode.
But it's actually fairly simple once you break it down. A nanoantenna is just an antenna on the nanoscale. These resonate with longwave infrared radiation. And a thermocouple Well that's a component of circuitry that generates a voltage when one part of the thermocouple is a different temperature than other part. So you pair these two together and the antenna generates heat and the thermocouple generates voltage. It could actually help increase the efficiency of solar panels. Now like I said, nanotechnology is a young science and it has lots of different applications.
Across many disciplines. And I'm really excited how such a small technology could have such a huge impact. That leads me to this week's question. When I say the word nanotechnology what do you imagine What does that word mean to you Let us know in the comments below. Then, do me a nanosized favor and share this tutorial with your friends.

DIY Solar Panel System Cost
The total of the system and materials was $22K. I ended up spending about another $1,800 in permit fees and a structural engineer and $400 for an electrician, several hundred dollars for a guy to come help me out for the two afternoons he spent with me. Xcel Energy gave me $16,538 rebate. Fix cost based on the number of kilowatts you are installing and has nothing to do with how much you pay the permit office or the electrician. My final cost after rebate was $7,237. I started my research in solar probably about a year before I actually installed it went.
And got a couple of bids from some of the local solar people both from contractors that my friends have used as well as just searching the internet and while talking to one of the guys I find of developed a good feeling from him, and I asked the question Would it be possible to do some of the work myself and kind of learn along the way he said Sure I absolutely support the doityourselfer DIY so I said why don't you throw me bids, what it would cost just come home and have solar one day and what it would cost to have.
It done where I do some or all the work myself. And throw them both to me and I said let's try the second one. The guys name is Steve Cross from Sun Spot Solar. I gave him my electric bills and said this is how much I think I need to generate and he said I agree and lets do these types of panels 180 watts each, you will need some where around 19 to 22 we figured out 21 fit pretty well. So I went and got all the permit information from Golden, filled it out. He came by 12.
Hour one day he type all the Xcel application on the internet and I kind of ran the process and when I had a question I would just send him an email and he helped me out. I think in parallel we order the equipment he dropped off in my driveway. Then one of his installers came out and helped me for two afternoons and I pretty much myself put in the whole rack system on the roof and the installer came out and helped me kind of a two man job carrying the panels up, putting the panels down and bracketing them down.

VISIONS CTRLP Australias Largest Solar Cells
Melbourne researchers have successfully created Australia's largest and most flexible solar cells, with the aid of a new printer located at CSIRO. The scientists are part of a collaboration between research and industry partners called the Victorian Organic Solar Cell Consortium VICOSC. This was achieved through the collaboration between The University of Melbourne and the Bio21 Institute, CSIRO, Monash University and industry partners including Bluescope Steel and security printing firm Innovia Security. In just three years the consortium has gone from making cells the size of a fingernail, to cells 10 centimetres square.
They are now able to print organic photovoltaic cells the size of an A3 sheet of paper. The consortium is now leading the world in the ability to print solar cells and using different printing technologies, but this is the beginning of the story. We're still developing the technologies, still developing the materials to enable us to print in a number of different ways for different applications. The new printer can roll out 10 metres of solar cells per minute, which is equivalent to producing one cell every two seconds. Using semiconducting inks, the researchers print the cells.
Straight onto paperthin flexible plastic or steel. So what we're looking at is, how can we use this technology in the short term, how can we print solar cells to enable advertising, can we put solar cells on to advertising material in shopping centres to drive an active display. So if somebody wants to advertise something with nice flashing lights then at the moment they drive that with batteries. In the longer term we see these materials being able to be coated on to buildings, into windows and on roofs to provide.
Power in a wide variety of locations and circumstances. As part of the consortium, graduate students working alongside scientists are involved in training and development programs to improve the technology in the long term. We're now right up there with the rest of the people in the world but we've also got a facility which is different. We now have a process through our collaboration where we take things from the very very beginning, from designing materials, from making devices in the lab scale right through the large scale printing, which is very very unusual in the world context.
Sun Monitor Ericsson Application Awards 2013
Cities are fun places They offer vast collection of experiences, that enrich your daily life. But all that comes with a price! A high demand of power. And we know what that means! High energy prices and pollution. Fortunately, more and more people are willing to contribute to greener planet by shifting to renewable resources. With the development of solar panel technology and government incentives solar panels are now available to citizens who care about environment Now you can have solar panels on the top of your roof. The power your solar panel generates can not only supply your household, but you can also sell it to electricity company.
That's a great investment, isn't it But here's a problem, current ways to track energy output are suited only to people that really understand how those systems work. Let's take a peek. The energy generated from solar panel is converted from DC to AC by the inverters. Then they send the energy to power grid. And this process is monitorized by your personal computer. This means you have to keep you computer running 24 by 7. What a waste of energy Plus, if you want to make your solar power output accessible onthego you need to expose your PC on the dangerous Internet.
If your PC went down, you lose everything. Now, our solution resolves all this. We replace your PC with a customized plug play device. it is small and very energy efficient. Moreover it will relay power output data to our cloud service, so that your data is safe and accessible anytime, anywhere. With our Android application or crossplatform web app, you can keep yourself uptodate Wait, it doesn't ends here! If electricity company can have accurate readings on solar power output by regions, then they can adjust energy production and reduce energy waste.
How Solar Systems Planets Evolve
The places where stars and planets are born are among the galaxy's most beautiful locales. These cosmic landscapes change as new generations of stars light up and disperse their birth cloud. But the youngest stars seen here are already perhaps a million years old, hardly toddlers. Stars and planets form in the dark, inside vast cold clouds of gas and dust, such as these pillars imaged by the Hubble Space Telescope. The dust is so thick we can't see the infant stars inside, at least not with visible light. With infrared light, Hubble can see through all but the thickest dust. Yet it's in those.
Dense knots that the youngest stars are forming. To peer inside them, astronomers need the James Webb Space Telescope. With a mirror larger than Hubble's, and performance optimized for the infrared, Webb will give astronomers their closest look yet at stellar birth. We're flying through a computer model that represents astronomers best ideas about the star formation process. Reddish area indicate thicker dust, the temperature less than 400 degrees below zero Fahrenheit. Or less than 240 degrees below zero Celsius. That pinwheel ahead is a protostar, perhaps 10,000 years old. Protostars arise when a.
Dense knot of dust, less than a light year across, collapses. But the details of the process are not well known. Elsewhere in the cloud, another protostar is preparing to build planets. As the star that created the protostar collapsed, it flattened into a disk. The disk we see here is 600 times the Earth's orbit around the Sun. If placed in our solar system, it would extend far beyond the planets. In this computer model, the disk continues to accumulate gas and dust from its surroundings for thousands of years. Eventually the disk fragments, producing dense, bright structures.
FYI Four Main Types of Solar Systems
Hi, and welcome to FYI , a new informational tutorial series from Wholesale Solar. My name is Josh Roelofs and today we're going to talk about the different types of solar systems available. The first and most common option for a PV system is a gridtied power system in which the solar panels and your inverter is tied into the household electrical system and it simply offsets your energy usage. A gridtied system offers the lowest overall system cost, fastest return on investment. It saves money on energy expense by sending energy back into the grid and turning your.
Meter backwards. It's ideally suited for people who are trying to save money on energy costs. The drawback to a gridtied system is that it does not offer protection from power outages. When the power goes out, your gridtied system is going to shut down. So if you're in an area where the power is unreliable, or you want to protect against power outages, you'll want to consider one of our other options. A gridtied with battery backup system is going to offer the best and most comprehensive features for most people. It can provide backup power to your appliances during a power outage.
It can also turn back your meter to offset energy costs. This system is especially suitable for people who live in an area where the power is unreliable or people with critical equipment like computers, or a pump, or something you need to run during a power outage. Like coffee. Gridtied with battery backup is going to offer a combination between cost savings and independence from the power grid. An offgrid system is completely independent from the power grid. It's especially great for areas where there's no grid power available, or where it's incredibly expensive to bring.
In the power grid. You can literally buy land anywhere and install your own power system. This offers the highest level of independence for people who are seeking selfsufficiency. However, there's a price for that independence. The batteries are going to wear out quicker because they're being cycled every day. Typically they'll be replaced every 510 years, depending on the system. BUT. did I mention total independence A gridassist system works similar to and uses the same equipment as an offgrid system. Solar panels recharge your batteries and your appliances run off the battery system.
The difference is A gridassisted system can use the power grid as a backup power source. The grid will turn on automatically when the batteries are low, because it's nighttime, or because there's not enough solar power to support your appliances. This will save you some money on your energy bill, especially if you're in an area where they charge higher rates during the day based on TimeofUse Metering. These are your 4 main system options available from Wholesale Solar. If you have questions or need more information, feel free to check out our website or give.
