Polysilicon prices remain stable following the gain before lunar New Year, as disappointing result of price negotiation in downstream raises doubts about the strength of demand. As polysilicon prices in China hit near the saturation points, there is not much rooms for polysilicon suppliers to improve the prices. In addition, as the demand after lunar New Year holiday seems weaker than anticipated, there are also no driving forces to push up the price further. While the price rally in China tempers, polysilicon suppliers in overseas also tend to stabilize their prices as well. As the result, overall polysilicon prices stay unchanged this week.
Renewable power generation technologies are now cost competitive with fossil fuels in a new report from Lloyd's Register
Renewable power generation technologies are now cost competitive with fossil fuels and innovation is gathering pace across the sector, finds a new report by Lloyd's Register. But which technologies will have the most impact on the industry?
Reuters Jim Drury: Swiss start-up Insolight says its solar panels double the yield achieved by other sun-powered technology. In independent tests the panels reached an efficiency of 36.4 percent. "Traditionally the market sits at around 18 percent and we can double this. Therefore we can double the return on investment for the final client....Our key innovation is that you do not need to rotate the panel in order to follow the sun. We can follow the sun in a flat manner, like any other solar panel, which makes it that our panel can be installed on standard rooftops, with standard mounting technology." Tiny square super cells capture all of the sun's rays, underneath round lenses, using a patented microtracking system. Watch Video.

Smart meter deployments are the most common smart grid (or smart utility) activity. Utilities are also adding sensors into their networks to better understand operating conditions.
Lacy Cooke for Inhabitat: One way China is working to battle climate change-causing carbon emissions is by developing a vast army of renewable energy projects. Even as the country struggles with pollution, it has made great strides on clean energy. They’re now the largest producer of solar energy by capacity in the world, adding 34.54 gigawatts of the country’s installed capacity of 77.42 gigawatts last year alone. The country’s National Energy Administration (NEA) announced over the weekend that in 2016, installed photovoltaic capacity in China more than doubled. Their data revealed the jump to 77.42 gigawatts after the country added 34.54 gigawatts. The provinces in which capacity increased most include Shandong, Henan, and Xinjiang, which is also one of the provinces with the largest overall capacity. Gansu, Inner Mongolia, and Qinghai join Xinjiang in that latter category. Cont'd...
CEZ Group acquired eight wind farms from project developer wpd. The majority of the wind farms, which have a total of 35 wind turbines and installed capacity of 85.25 MW, are located in the northern part of Germany. The leading Czech energy supplier relies on TÜV SÜD's expertise for the necessary technical due diligence.
The Water-Energy Nexus Conference, February 28-March 1, 2017 in Los Angeles (www.water-energy-nexus.com) zeros in on the challenges facing water-energy efficiency programs, technology advances that can help drive efficiencies and cost savings, and successful case studies of joint water-energy optimization initiatives. The event is unique in that it brings together startups, investors, business strategists, regulators, energy companies, water companies and technology innovators for two days of networking and sharing of insights into maximizing one of the most precious resources of our time.

Mark Gilbert for Bloomberg: The U.K. government is mulling whether to support a 1.3 billion pound ($1.6 billion) proposal to build a tidal lagoon in South Wales. It should stop dithering and subsidize the project to help meet the country's green energy goals, produce cheaper power, and establish Britain as the world leader in technology that harnesses the power of the tides to generate electricity. The U.K. lost its energy independence in 2004, and now depends upon imports to meet about half of its energy needs. And while the contribution from renewable energy sources has climbed to a bit less than 10 percent from about 1 percent at the start of the last decade, the U.K. commitment to reduce carbon emissions to 57 percent of their 1990 levels by 2030 means even less electricity needs to come from coal-fired power plants.

Move sets new standard for PERC (passivated emitter rear contact) solar panels
With prior studies into perovskites focusing on bulk recombination, one area left unexamined until now concerned the surface recombination in lead iodide perovskites. NREL's scientists determined recombination in other parts of a methylammonium perovskite film isn't as important as what's happening on the surface, both the top and bottom. Matthew Beard and his colleagues within NREL's Che
Following is a statement by Abigail Ross Hopper, president and CEO of the Solar Energy Industries Association (SEIA), on today's override by the Maryland Legislature of the veto of the Clean Energy Jobs Act:
Sue Holmes for Phys.org: People think of corrosion as rust on cars or oxidation that blackens silver, but it also harms critical electronics and connections in solar panels, lowering the amount of electricity produced. "It's challenging to predict and even more challenging to design ways to reduce it because it's highly dependent on material and environmental conditions," said Eric Schindelholz, a Sandia National Laboratories materials reliability researcher who studies corrosion and how it affects photovoltaic (PV) system performance. Sandia researchers from different departments collaborate to accelerate corrosion under controlled conditions and use what they learn to help industry develop longer-lasting PV panels and increase reliability. For example, work by Olga Lavrova of Sandia's Photovoltaic and Distributed Systems Integration department demonstrated, for the first time, a link between corrosion and the risk of arc faults in PV systems' electrical connections. Research by Erik Spoerke of Sandia's Electronic, Optical and Nano Materials department focuses on developing new nanocomposite films that could dramatically increase reliability. Cont'd...
