SolarCity to develop roofs made of solar cells

Lucas Mearian for ComputerWorld:  Five million roofs are replaced each year in the U.S., so instead of simply swapping out old shingles with new ones, why not turn the whole roof into a solar power generator that's integrated with your home's electrical utility? That is SolarCity's plan for a new product it expects to begin producing next year, according to statements made during the company's second-quarter earnings calllast week. During the call, SolarCity Chief Technology Officer Peter Rive alluded to a new product that would be produced at the soon to open Buffalo, N.Y., solar panel manufacturing facility. Then SolarCity co-founder and Chairman Elon Musk interjected and said the product would be a solar roof, "as opposed to a [solar] module on a roof."   Cont'd...

Wind power fiercer than expected, study finds

Phys.org:  University of Delaware researchers report in a new study that offshore wind may be more powerful, yet more turbulent than expected in the North Eastern United States. The findings, published in a paper in the Journal of Geophysical Research: Atmospheres, could have important implications for the future development of offshore wind farms in the U.S., including the assessment of how much wind power can be produced, what type of turbines should be used, how many turbines should be installed and the spacing between each. The study, led by Cristina Archer at UD and Brian Colle at Stony Brook University, analyzed historical data from 2003-2011 at the Cape Wind tower located near the center of Nantucket Sound off the coast of Martha's Vineyard, Massachusetts, and collected complementary data at the same location in 2013-2014. Co-authors on the paper, titled "On the predominance of unstable atmospheric conditions in the marine boundary layer offshore of the U.S. northeastern coast," include UD professors Dana Veron and Fabrice Veron, and Matthew Sienkiewicz from Stony Brook. The paper's main finding is that atmospheric conditions around Cape Wind are predominantly turbulent, or unstable, which is in stark contrast to prevailing data from European offshore wind farms in the Baltic Sea and the North Sea. European studies of offshore wind document that atmospheric conditions there are predominantly neutral— meaning neither too windy nor too still, but somewhere in the middle, with unstable wind conditions occurring only 20 percent of the time.  Cont'd...

Floating solar power sector has "considerable" bank support

Mark Lammey  for EnergyVoice:  A major bank’s decision to throw its weight behind a floating solar power scheme shows the sector is rich with commercial potential, bosses at engineering consultancy OST Energy said. OST acted as technical adviser for Royal Bank of Scotland (RBS) during the early stages of the project to bring Europe’s largest floating photovoltaic solar project to financial close earlier this year. The 6.3 Megawatt peak (MWp) array, installed by Lightsource Renewable Energy, is the first project of its kind to secure European bank financing. It now provides a source of clean energy to water utilities company, Thames Water, on the Queen Elizabeth II reservoir west of London. Thames Water will buy all energy generated by the project as part of a power purchase agreement (PPA) with Lightsource.   Cont'd...

How To Access Financing For Your Next Commercial Solar Project

Borrowers may underestimate the extent to which they need to be prepared before soliciting project financing. There are six key documents essential for obtaining capital for financing any solar project.

Nevada Court Rejects Solar Power Ballot Initiative As 'Inaccurate' And 'Misleading'

Samantha Page for ThinkProgress:  The Nevada Supreme Court on Thursday rejected a solar industry-backed measure that would have let voters decide how customers are paid for the electricity they put back on the grid. The November referendum would have allowed voters to overturn a Public Utilities Commission (PUC) decision from late last year that gutted the state’s net metering program — a rate design element that ensures solar owners are paid retail rate for the electricity they put back on the grid. The court ruled that the description included in the referendum was “inaccurate,” “misleading,” and “argumentative,” the AP reported. But the industry was not bowed after the ruling, saying it would continue to fight to set fair rates for solar homeowners.   Cont'd...

Chernobyl is to become the world's largest solar power plant

ALEXANDRU MICU for ZME Science:  The Ukranian government plans to turn Chernobyl, the site of the world’s most famous nuclear meltdown, into a sprawling solar power plant — the largest in the world. Since the meltdown on April 26, 1986, no one’s been able to find any good uses for Chernobyl. A 1,600 square mile area was drenched in radiation and deemed an “exclusion zone,” so everyone was evacuated after the clean-up efforts were concluded and the plant was sealed in its ubiquitous sarcophagus. The buildings, goods, and infrastructure in the area were abandoned so fast that the city looks like time froze there 30 years ago — albeit with a Falloutesque look. Since we left, nature took over, and for the most part, is thriving in our absence (though the microbes that decompose dead organic matter seem to be having a hard time living here.) In a recent interview, however, Ukraine’s ecology minister Ostap Semerak said that the government is negotiating with two US investment firms and four Canadian energy companies to develop Chernobyl’s solar potential. The area is uniquely suited for the purpose — the land is extremely cheap, much of the required infrastructure, such as roads are already built. Even better, the power lines that served the old 4GW reactor are still useable.   Cont'd...

Tesla Lowers Bid, Agrees to Pay $2.6 Billion for SolarCity

Chris Martin for Bloomberg Technology:  Elon Musk’s Tesla Motors Inc. reached an agreement to buy SolarCity Corp. for $2.6 billion, about $300 million less than an initial proposal criticized as a “bailout” for the solar company in which he’s the largest shareholder. SolarCity investors will receive $25.37 a share in stock under the agreement, according to a statement Monday. Musk initially offered $26.50 to $28.50 a share in Tesla stock. Analysts have said in the past that the bid was too low and investors have questioned the wisdom of Musk combining his electric-car maker with the clean-energy company.  The deal, which allows SolarCity to solicit competing takeover offers through Sept. 14, will now go to the shareholders of the companies for approval.   Cont'd...   

Molten storage and thermophotovoltaics offer new solar power pathway

Georgia Institute of Technology:  New computer modeling suggests that high temperature TPV conversion -- which captures infrared radiation from very hot surfaces -- could one day rival combined-cycle turbine systems when combined with thermal storage using liquid metal at temperatures around 1,300 degrees Celsius. Advances in high-temperature components and improved system modeling, combined with the potential for conversion costs an order of magnitude lower than those of turbines, suggest that TPV could offer a pathway for efficiently storing and producing electrical power from solar thermal sources, a new study suggests. The underlying technologies of high temperature storage and thermophotovoltaic conversion could also be used to produce grid-scale batteries able to rapidly supplement other power sources by storing heat for quick conversion to electricity. The research, supported by ARPA-E, was reported July 4 in the journal Energy and Environmental Science by researchers at the Georgia Institute of Technology.   Cont'd...

Flight to the future: Solar Impulse shows we can run the world without consuming the earth

The lessons of Solar Impulse are clear: by pushing the boundaries of technology, and refusing to accept limits, technological or psychological, we can run the world without consuming the earth, and reach heights we never believed were possible.

Using Particle Accelerator Technology to Manufacture Solar Cells

This technique is projected to reduce solar panel manufacturing costs by upwards of 60% compared to industry standards, while making them 25% more efficient, and resulting in a very cost-effective source of energy.

Belgian scientists make novel water-from-urine machine

Reuters:  A team of scientists at a Belgian university say they have created a machine that turns urine into drinkable water and fertilizer using solar energy, a technique which could be applied in rural areas and developing countries. While there are other options for treating waste water, the system applied at the University of Ghent uses a special membrane, is said to be energy-efficient and to be applicable in areas off the electricity grid. "We're able to recover fertilizer and drinking water from urine using just a simple process and solar energy," said University of Ghent researcher Sebastiaan Derese. The urine is collected in a big tank, heated in a solar-powered boiler before passing through the membrane where the water is recovered and nutrients such as potassium, nitrogen and phosphorus are separated.   Cont'd...
