PVinsights: Polysilicon Rout Sends Downstream Components Slumping
The slump of polysilicon price has initiated since late August as buyers buying power has been significantly hampered due to slashed downstream demand and prices that they could not bear with high-priced raw materials and threaten to cut more polysilicon procurements. A previous attempt to sustain polysilicon prices in China has failed and the polysilicon suppliers in China have lowered price drastically in order to lessen its piled-up inventories as well as to secure limited orders. Moreover, as the quarterly financial accounting process closes at the end of September, polysilicon suppliers are having compounded pressures to dump excess stockpiles, pushing down polysilicon prices further.

Why large-scale wind power is so hard to build
Michael McDonald, Oilprice.com via USA Today : he Bureau of Land Management faces a problem and wants to shake up the rules around wind farm approvals. The problem is straight-forward on its face, but difficult to reconcile logically: Why are so few new large-scale wind projects being built? Despite the fact that nearly everyone – environmentalists, government regulators, and business interests –wants to build more wind farms, precious few are making it over the goal line.
Since 2009, the Obama Administration has approved 46 wind farm projects that would cover a proposed 216,356 acres of public land. Yet only 15 of these 46 projects have made it into operation. The rest are stuck in limbo with years of mandatory environmental analysis ahead or have been cancelled outright. Cont'd...
Market entry Down Under: BayWa Group acquires Australian PV distributor Solarmatrix
BayWa AG, Munich, through its subsidiary BayWa r.e. renewable energy GmbH, acquired the photovoltaic distributor Solarmatrix based in the West Australian city of Perth and thus enters the solar module and components business in Australia. The activities of Solarmatrix will be continued with the company BayWa r.e. Solar Systems Pty Ltd. formed specifically for this purpose.
Transparent solar panels are 50 times more productive than regular photovoltaics
Luke Dormehl for DigitalTrends: As the term “regular windows” suggests, users don’t have to replace the existing windows in their home, but need only treat them with a special process developed by the company.
“We apply liquid coatings to glass and plastic surfaces at ambient pressure, and dry these coatings at low temperature to produce transparent films,” Conklin continued. “We repeat these processes, and then collectively these coatings — and thus the glass and plastic surfaces — generate electricity.”
Of these coatings, the most important is the so-called “Active Layer,” through which electricity is generated by the absorption of light, and the transparent conductors, which allow the electricity to be extracted. “[The] coatings are primarily organic, primarily from carbon, hydrogen, nitrogen, and oxygen,” Conklin said. “We are constantly refining each of the layers to improve on the power we’re able to extract from these coatings and enhance their manufacturability.” Cont'd...
Solar cell is more efficient, costs less than its counterparts
Massachusetts Institute of Technology via Science Daily: A team of researchers from MIT and the Masdar Institute of Science and Technology may have found a way around this seemingly intractable tradeoff between efficiency and cost. The team has developed a new solar cell that combines two different layers of sunlight-absorbing material to harvest a broader range of the sun's energy. The researchers call the device a "step cell," because the two layers are arranged in a stepwise fashion, with the lower layer jutting out beneath the upper layer, in order to expose both layers to incoming sunlight. Such layered, or "multijunction," solar cells are typically expensive to manufacture, but the researchers also used a novel, low-cost manufacturing process for their step cell.
The team's step-cell concept can reach theoretical efficiencies above 40 percent and estimated practical efficiencies of 35 percent, prompting the team's principal investigators -- Masdar Institute's Ammar Nayfeh, associate professor of electrical engineering and computer science, and MIT's Eugene Fitzgerald, the Merton C. Flemings-SMA Professor of Materials Science and Engineering -- to plan a startup company to commercialize the promising solar cell. Cont'd...

PVinsights: Global solar prices deepens as polysilicon collapse
Polysilicon prices start to collapse obviously this week, particularly the price in China with more than 4% drops. The scope of polysilicon price correction was not enough, in contrast to the downstream components in August, leaving the stockpiles continues to pile up over the period as the trading were less active. However, as entering into a quarterly financial end in September, the increasing inventory pressure compound by sluggish downstream demand and slashed wafer prices eventually compromise Chinese polysilicon suppliers on adjusting prices quotes down dramatically. On the other hand, polysilicon prices out of China also extend the slump this week, but the price corrections are less noticeable than in China since the price baseline is much lower than that in China. As the result, without seeing any sign of global demand recovery that could possibly alleviate serious global supply glut soon, polysilicon supplier are forced to provide more price discounts in order to lessen the stock levels .

Making waves: Shetland tidal power breakthrough is another world first for Scotland
Martin Hannan for The National: HOUSEHOLDERS on the Shetland Isles were not aware of it, but when they plugged in their kettles recently, they were sharing in a bit of history.
For the Shetland Tidal Array at Bluemull Sound, installed by Nova Innovation of Edinburgh, has become the world’s first tidal power array to be connected to a grid and deliver power on a commercial basis – to dozens of homes on the islands.
The achievement has been hailed by environmentalists and the renewable industry as a turning point in the development of marine power.
Nova had shown its technology could work with a single turbine which generated electricity in March. But the installation of second turbine that is also working to the grid proves that large tidal power arrays can and do work. Commercially viable tidal power is seen as something of a Holy Grail by the industry, since it is one of the few renewable energy sources that is entirely predictable – as one industry source once put it: “there will be tidal power available as long as the moon is in the sky”.
