Frenell publishes White Paper on Direct Molten Salt Solar Technology

As a major breakthrough, the White Paper presents how the cost of electricity for DMS® CSP plants can be lowered to 5 to 7 US$Cents per kilowatt-hour when designed for base load power generation with more than 15 hours thermal energy storage.

Riding the 'Solarcoaster' as Shares Plunge Even More Than Coal

Joe Ryan & Brian Eckhouse for Bloomberg:  For all the upbeat forecasts about the growth of solar power, this is a punishing year for the industry. And it won’t improve anytime soon. SunEdison Inc., the world’s biggest clean-energy company, is bankrupt. Yingli Green Energy Holding Co., once the top panel maker, warned it may be inching toward default. And SolarCity Corp., the largest U.S. rooftop installer, plunged as much as 27 percent Tuesday after scaling back its installation forecast for the third time in seven months.  They’re not alone. A Bloomberg index of 20 major solar companies has slumped more than 30 percent this year. Soaring installations and growing global demand for clean energy is being trumped by investor concerns that the debt-fueled strategies employed by SunEdison, Yingli and SolarCity are endemic to the industry and dangerous for shareholders. “They call it the solarcoaster for a reason,” said Nancy Pfund, managing partner of DBL Partners and a SolarCity director. With so much happening, both positive and negative, “it’s been hard for investors to follow.” At a time when falling prices, renewed U.S. tax breaks and the Paris climate deal are fueling solar sales worldwide, solar shares are performing even worse than coal stocks.   Cont'd...

Solar Cell "Wonder Material"-Perovskite-Falls Short of Expectations

Hugh Cowley for Scientific American:  Perovskites have arguably transformed solar energy more in the last few years than other technologies have in decades. But British researchers have called into question optimistic predictions of undiscovered perovskites. Hybrid perovskites are a mix of organic and inorganic ions with the same crystal structure as calcium titanium oxide (CaTiO3). Halide perovskites are a subset of these structures containing halide ions such as fluoride or chloride. Iodide perovskites such as methylammonium lead iodide (CH3NH3PbI3) can convert sunlight to electricity. Researchers use a decades-old geometric 'tolerance factor' to propose new combinations of ions that will form stable perovskites. Now, Robert Palgrave and his team at University College London, UK, have reassessed the validity of the tolerance factor in predicting new hybrid perovskite structures.  Cont'd...

Solar power is contagious. These maps show how it spreads.

Brad Plumer for VOX :  Rooftop solar is expanding rapidly in the United States — by some estimates, a new system goes up every four minutes. There are plenty of reasons for that, from falling prices to generous federal subsidies to innovative leasing schemes. But there's another, little-discussed factor here: Residential solar power is contagious. Yep, contagious. Studies have found that if you install solar photovoltaic panels on your roof, that increases the odds that your neighbors will install their own panels. SolarCity, the largest solar installer in the United States, just published some fascinating data on this "contagion" effect. The company has installed 230,000 rooftop systems nationwide (often by allowing customers to lease panels rather than buy them upfront). It says fully one-third of customers were referred by a friend or neighbor. SolarCity has also made some neat animations showing the "contagion" effect in action.   View here:

PVinsights: Solar panel prices slump as global price competition intensifies

Solar panel prices extend losses this week, as Chinese module makers leverage price competition intensively over the globe, especially in the US. Amid waning demand in China, some Chinese module maker is rush to increase the shipment volume in rest of the world, particularly in the US, in order to be the dominant module manufacturer. Since the demand in the US is widely expected to be promising in the coming five years, Chinese module makers has been aiming the US as one of the major target market to penetrate with their overseas capacities. Hence, solar panel price in the US has encountered great pressures, as Chinese module makers fuel strategic pricing intensively in the region. Meanwhile, in China, SEA and India, the regional prices are under pressured as Chinese module makers also intend to leverage price competition to capture more market shares.

How much noise is produced by wind turbines?

Phys.org:  Wind energy is to have a major share in the future renewable energy mix. The Germany-wide TremAc project is aimed at improving the planning, development, and acceptance of wind power plants and at developing objective criteria for their emissions. For this purpose, experts will study the interaction of acoustic and seismic vibrations of wind power plants and plan to generate a model to compute both emissions. TremAc is funded with EUR 1.85 million by the Federal Ministry for Economic Affairs and Energy. "We want to compute the complete chain of effects from the plant to the population," Theodoros Triantafyllidis, coordinator of the TremAc cooperation project and Head of the Institute of Soil Mechanics and Rock Mechanics of KIT, explains. Within the framework of the TremAc cooperation project, a single chain is to be developed for modeling all vibrating plant components and the surroundings, i.e. the rotating rotor blades, drive shaft, gondola suspension and tower structure, foundation, and the ground, various topographic terrains and airflows as well as adjacent residential buildings and workplaces.
