SolarCity Unveils Worlds Most Efficient Rooftop Solar Panel with more than 22 Module Efficiency.
The Sun provides endless energy, but the average solar cell panel can convert only 14 to 20 of the energy it collects into usable electricity. Now, American energy company SolarCity has built the world's most efficient rooftop solar panel, with a module efficiency exceeding 22 percent. The new SolarCity panel generates more power per square foot and harvests more energy over a year than any other rooftop panel in production, and will be the highest volume solar panel manufactured in the Western Hemisphere. SolarCity will begin producing the first modules in small quantities this month at its 100.
MW pilot facility, but the majority of the new solar panels will ultimately be produced at SolarCity's 1 GW facility in Buffalo, New York. SolarCity expects to be producing between 9,000 10,000 solar panels each day with similar efficiency when the Buffalo facility reaches full capacity. SolarCity's panel was measured with 22.04 percent modulelevel efficiency by Renewable Energy Test Center, a thirdparty certification testing provider for photovoltaic and renewable energy products. SolarCity's new panel is created via a proprietary process that significantly reduces the manufacturing cost relative to other highefficiency technologies, and it.
The Future of Solar Energy is TINY Technology!
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.

How Solar Energy Is Converted To Electricity Through Solar Panels
Sunlight is made up of tiny packets of energy, called photons. Every minute, enough of this energy reaches the earth to meet the world's energy demand for a whole year. Photovoltaic panels consists of many solar cells, these are materials made like silicon, one of the most common elements on earth. The individual cell is designed with a positive and a negative layer to create an electric field, just like in the battery. As photons are absorb in the cell, their energy causes electrons to come free. The electrons move towards the bottom of the cell, and exit through the connecting wire. This flow of.

The solar industry is very, very focused on improving efficiency and reducing the cost. Our attempt here with this research is to propose a new way of looking at these structures and saying, well, you can use existing materials and nothing really needs to change very much. You just shape them in different ways that gives you this benefit. Kirigami is a Japanese art that's related to origami where origami is really about folding of things and kirigami is about cutting things. A colleague of mine who is an artist, Matthew Shlian, he had some interesting.
New shapes and when you pulled on the sheet of paper the cuts would sort of begin to buckle and deform in a very controlled way and so I realized at that point that we could look at that structure as a hyperminiaturized version of solar trackers. Conventional solar tracking has been used for many, many years. The mechanism itself cost quite a bit of extra money. What people end up doing as they say, well, since the mechanisms gonna cost all this extra money. we might as well put a really big panel and then eventually you end up with.
Something that's really big and really heavy. When you think about putting this type of thing on a rooftop it's very very difficult and in most cases is just purely impossible. It was a fairly lengthy process because the things that you do in paper don't automatically translate to other materials and so I started talking to my colleague, Stephen Forrest, about using some of their very high efficiency gallium arsenide solar cells. They're pretty thin, less than 2 microns thick that's ten to fifty times thinner than the thickness of a human hair. What the new design allows us.
To do in contrast to conventional tracking is it basically allows us to work with the same form factor. It doesn't catch the wind, it doesn't weigh any more than a conventional solar panel might and the thing that it buys you is that you can use less semiconductor to gather the same amount of energy. A third less material to generate the same total amount of energy that you would otherwise. Which means that in turn that I could decrease the cost of installation because there are fewer panels to install but you do require little bit of extra area. When you.
Multiply it by the total number of solar installations it's kind of like a billion dollar value proposition potentially. I guess it looks simple enough, kind of like something that you could do on your kitchen table, things don't have to be complicated for them to work. If this can be shown to be quite reliable, then the net benefit could be quite big. V.O. These candies which are already pretty soft should be about 10 to 100 times stiffer than the silicone. So the material that we're working with in the lab is really really soft.
Can Korea take lead in Solar Panel Industry ,
Solar power is the biggest and fastest growing sector in the renewable energy market as it's expected to become an affordable and feasible alternative to fossil fuels. Korea is making increasing use of this energy source. but it is going to be a global player For this week's Industry Insight, here's Song Jisun. This is the biggest solar power plant in the capital that started operating this summer. It's equivalent to 13 football fields with a capacity of 5point6 megawatts enough for 22hundred households a year. Solar energy is quickly rising as the next.
Generation of renewable energy here in Korea accounting for 98 percent of all renewable power plants built in the first half this year. This solar panel system has been set up on the roof of this waterfiltering plant and we have completed a couple of other solar power facilities like this for the Seoul Metropolitan Government. It's fully operational even on cloudy days and only takes three months to install and operate. The market for these solar facilities is booming in Korea. with most being bulit by government or public agencies. Over the past decade. solar energy has emerged.
As the world's biggest source of renewable energy, overtaking wind power. Last year alone it created half of total electricity generated from renewable energy sources. This prospective market is forecast to expand by 10percent each year by 2030. with China and India likely accounting for half of the global demand. By then, the cost of generating electricity from solar power is expected to reach similar levels to burning fossil fuel meaning it could become more widespread without the support of government subsidies. as it mostly depends on at the moment.
The biggest competition in the industry comes from China which produces 80percent of the global demand. at prices 20 to 30 percent cheaper than Korea. Backed by government support, Chinese companies have been producing well over the market demand. with half of the world's top 10 solar panel producers based in China. It's not easy to counter them in terms of price, so Korean firms must improve their costefficiency, at the same time revving up quality and technology. Around 40 players are in Korea's solar power generating market with small and midsized.
Companies focusing on solar cells or modules. while large conglomerates aim to tackle the global market by equipping a complete chain of production to service. We've established a value chain from solar component production to system maintenance. And we aim to expand the solar power generation infrastructure to even include households. Industry experts point out that it is also crucial the government take steps to speed up growth of the domestic solar power industry. To expand its economy of scale and improve its profitability, they add. Korea needs to ease regulations concerning installation.
Why Should We Launch Solar Panels Into Space
This episode of DNews is brought to you by Full Sail University. This week the Japanese Aerospace Exploration Agency announced it wants to get solar power from space. I'm having flashbacks to disasters from SimCity2000. Hello! I'm Trace. Thank you for watching DNews. Back in the 1960s, American aerospace engineer Peter Glaser proposed launching solar panels into space, and beaming the power they collect back to the surface for our use. Since the late 60s the idea has been in a holding pattern mainly because of the expense and worries about maintenance and equipment, but thanks.
To recent developments in solar panel tech the Japanese space firm JAXA says they can finally try it. The plan is ambitious at minimum and cost hasn't yet been calculated, BUT JAXA is determined, and they're not the only ones. The U.S. Naval Research Laboratory is also interested in spacebased solar. The reason everyone's looking up, is because that's where the sun sits! If we can put a satellite in orbit to collect the sun's rays BEFORE the atmosphere filters them out, and without the worry of a cloudy day, that would be rad. The JAXA Space Based Power System.
Or SBPS will orbit 22,400 miles up, and if done to their specs, would completely replace a nuclear power plant by producing 1 gigawatt of electricity enough to power halfamillion homes. Their plan uses a 10,000 metric ton system, which is. well pretty ridiculous. The largest rocket ever launched was the Saturn V it took our boys to the moon and could only lift about 130 metric tons. Once the power is gathered, a converter in space will convert the electricity into a microwave beam not like in your house, literally waves of energy that are.
On the micro scale. Microwaves can be converted from energy at 80 percent efficiency, which means there would be some loss, but it would be pretty damn efficient about 48 of the power collected would reach consumers. Which doesn't sound great, but it really is. To make sure the array is getting sunlight 24hours a day, JAXA plans to put mirrors on either side of the planet to reflect sunlight at the collector all the time. The Japanese are announcing their plan so far in advance in the hope other countries.
Will gather and help realize the dream of solar from space. Once created, it could provide clean, unlimited energy anywhere on the planet, regardless of remote location. Here's the kicker. It would cost about a trillion dollars. Which sounds like a lot, but it's like 125 bucks per person on the planet in 2030. And that's WAY more than you're paying doe your power bill. Not to mention oil wars and all the pollution, ecological damage, mining and drilling that goes with fossil fuels. We've got commenting areaaassss, check them out and type your feelings on spacebased.
Solar so we can all talk about it! None of this would be possible without computers to run the system, and we need people to write the computer programs. Full Sail University in Florida offers courses to help train tech professionals by blending code and realworld experience. Students of Full Sail have handson access to technology on their first day, get a discounted laptop and all the software they'll need to earn degrees in software, mobile and web development.
