Dual_Axis_Tracker_Final_Report. The Effect of Azimuth Angle on Energy Output. Azimuth is the array’s east-west orientation in degrees.
In most of the solar PV energy calculator tools, an azimuth value of zero is facing equator in both northern and southern hemispheres. Positive 90 degrees is facing due west, negative 90 degrees is facing due east. The compass angle shows 180 for south, 90 for east and 270 for west. In northern hemisphere, between the latitudes of 23 and 90, the sun is always in the south. Therefore, the modules on an array are faced to south in order to get the most out of the sun’s energy. The north facing roof sides are obviously not suitable for installing solar panels in North America, whereas the east and west facing roofs could be acceptable. 5 breakthroughs that will make solar power cheaper than coal. There was some good news last week.
While Washington was busy holding the global markets hostage and placing billions in badly needed R&D funding on the chopping block, a new report from REN21 (the Renewable Energy Network for the 21st Century) showed that global investments in renewable energy jumped 32 percent to a record $211 billion, this despite a downturn in the economy and massive R&D cuts in clean energy. It's a little reassuring that progress marches forward, despite our nation's best efforts to stop it. Solar in particular appears to be growing in leaps and bounds due in large part to a 60 percent drop in price per kW (kilowatt) production in just the past three years.

This article was taken from the March issue of Wired UK magazine.
How I built a solar panel for 0 – You can too. Mike Davis - no hidden costs In this article I am going to describe how to build a photo voltaic solar panel for a fraction of the price you would pay a manufacturer.
I’ll show you how inexpensive materials and common tools can be used to make panels that rival commercial products in power production, but blow them away on price. Several years ago I bought a remote property in Arizona. I am an astronomer and wanted a place to practice my hobby far away from the sky-wrecking light pollution found near cities of any real size. You've been both eating and cleaning with this rainbow. Patent US7115811 - Semiconductor body forming a solar cell with a bypass diode - Google Patents.

How to Use Crystals to Generate Electricity. Potential Giant Crystal Pyramid Discovered in Bermuda Triangle [W/ VIDEO. Note: This story originated from claims by Dr Ray Brown that aired on The history channel.
There are simply not enough facts to say whether or not these new findings are true but nonetheless it is interesting and has some interesting elements to it. It is important to note that because something is not in mainstream media it does not mean it is fake, however this on simply doesn’t have much else to go along with it so we cannot say YES or NO about this one. Read at your own discretion. I highly recommend you watch the story of Dr Ray Brown in the video below. Largest solar sail ever to fly in 2014.

In the latest issue of Science, researchers from Lund University in Sweden have shown how nanowires could pave the way for more efficient and cheaper solar cells.
"Our findings are the first to show that it really is possible to use nanowires to manufacture solar cells," says Magnus Borgström, a researcher in semiconductor physics and the principal author.

Webcontent.acs.org/iyckit/booklets/IYC_Book.pdf. MIT startup makes transparent solar panel that will allow your smartphone to power itself. Transparent solar panels — think about it for a moment: Sheets of transparent glass or plastic film that also generate electricity. It’s almost the perfect solution for all our energy needs, generating free power from every available surface, window, and computer display. The concept of transparent solar panels isn’t new, of course, but it now looks like they’re finally finding their way to market: Ubiquitous Energy, a startup that was spun off from MIT last year, is developing a technology and patent portfolio and hopes to bring affordable transparent solar panels to market soon.
At this point, you might be wondering how transparent solar cells actually work — after all, if it’s transparent, how can it absorb light energy? The simple answer is that light energy comes in many frequencies (colors), but as far as we humans are concerned, it is only the visible wavelengths — from blue, through green and yellow, to red — that really matter. New principle may help explain why nature is quantum. Like small children, scientists are always asking the question 'why? '. One question they've yet to answer is why nature picked quantum physics, in all its weird glory, as a sensible way to behave. Researchers Corsin Pfister and Stephanie Wehner at the Centre for Quantum Technologies at the National University of Singapore tackle this perennial question in a paper published today in Nature Communications . Cleaner air with gold and copper.
SOL201O: Year On Earth Video. Azimuth-Altitude Dual Axis Solar Tracker. Solar power: the unexpected side effect. The solar amibtions of developing nations look set to deliver more than just electricity. How real are lead poisoning fears? As the UK lights up its 200th megawatt of solar power, China and India have revealed breathtaking solar ambitions that cast a shadow on the rest of the world. Come 2020, China intends to add 1.6GW of solar capacity while India plans to install a massive 12GW as well as 20 million solar lanterns by 2022.
But this wealth of low-carbon renewable energy may have unexpected environmental consequences. In September last year, US researchers reported that rapid solar power growth in China and India could lead to an unsavoury side effect: lead poisoning. Rapidly developing nations do not yet have the tightly regulated recycling infrastructure of, say, Europe and the US to safely process spent lead-acid batteries. The painful results are well documented. Already, China has witnessed numerous mass poisoning incidents from domestic lead battery manufacturing and recycling.
