U.S. Solar Market Adds More Than 2 GW in Q2 2016

Growing 43 percent year over year, the U.S. saw 2,051 megawatts (MW) of solar photovoltaic (PV) installed in the second quarter of 2016. According to GTM Research and the Solar Energy Industries Association's (SEIA) latest U.S. Solar Market Insight report, this marks the eleventh consecutive quarter in which more than a gigawatt (GW) of PV was installed.

Is solar power in nuclear disaster exclusion zones advisable?

ARNOLD GUNDERSEN for Bulletin of the Atomic Scientists:  My own experience near solar arrays in Fukushima Prefecture indicates that the problems of building and maintaining solar installations in a contaminated nuclear wasteland are over-simplified, and worse, totally ignored. One of the greatest burdens of maintaining operating atomic reactors is the cost of working in a Radiologically Controlled Area. (The Lawrence Berkeley National Laboratory defines a Radiologically Controlled Area as: “Any area to which access is managed to protect individuals from exposure to radiation or radioactive materials. Individuals who enter Controlled Areas without entering Radiological Areas are not expected to receive a total effective dose equivalent of more than 0.1 rem (0.001 Sievert) in a year.”) Each nuclear power plant operates with specific instructions and constraints, with Radiation Work Permits tailored for each specific maintenance activity. Because special clothing, special respiratory equipment, and special radiation monitoring equipment are routinely required to perform even minimum maintenance activities inside a nuclear power plant, every activity takes longer, costs more, and requires more people inside each reactor than necessary in any other industrial setting. Consequently, the question becomes: Does building solar panels on land contaminated with nuclear waste resemble work in a normal industrial setting, or is it more similar to work inside a radiologically contaminated atomic reactor—at significantly higher cost?   Full Article:

Is Rent-to-Own Solar Power the Answer?

Jason Overdorf for SMITHSONIAN.COM:  For a little more than a year, the family has been supplementing the sporadic electricity the village gets from the grid with solar energy, thanks to a new pay-as-you-go business model pioneered by Canadian entrepreneur Paul Needham and his company, Simpa Networks. Call it “rent-to-own solar.” Needham is a serial tech entrepreneur whose online advertising company BidClix made its way into the portfolio of Microsoft. As a doctoral student in economics at Cambridge, he was obsessed with the reasons customers will shell out for certain products and not others. One of the questions that always bugged him was, “Why don’t I own solar panels?” The reason, he determined, was the high up-front costs. Imagine if mobile phone service was sold like solar energy. From an operator’s perspective, it would have made great sense to try to sell customers 10 years of phone calls in advance, so as to quickly earn back the money invested in building cell towers. But the person who suggested such a strategy would have been fired immediately, Needham says. “You want to charge people for what they value, not the technology that’s providing it,” he says in a telephone interview.   Cont'd...

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...

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...
