Siemens pulls plug on last solar energy business

German industrial conglomerate Siemens (SIEGn.DE) is shutting down the last of its solar energy businesses after it failed to find a buyer, the company said on Monday. Confirming a report in German newspaper Handelsblatt, a spokesman for Siemens said the group would close Solel by early next year. The Israeli business has accumulated losses of around 1 billion euros ($1.33 billion) since Siemens bought it in 2009, including a write-off of the entire purchase price. Siemens has spent seven months trying to sell Solel, which makes components used in solar-thermal power stations. Some 280 employees will be affected by the closure, most of them in Israel. The cost will run into the mid-double digit millions of euros, according to Siemens. Once a promising new field with strong growth rates, the solar energy industry is in sharp decline in Germany as Chinese manufacturers flood the global market with cheaper panels and components.

Ask Bill Clinton: How Can We Encourage Homeowners to Adopt Solar Energy?

David Crane, CEO and president, NRG Energy (NRG) “With the cost of solar panels now just 10 percent of what they were five years ago, how do we streamline the local approval process and reduce the friction costs so that U.S. homeowners can realize the solar value of their property while paying less for their electricity?” We need to develop in every state a network of cooperation in which contractors, utilities, building and home owners, tenants, and government agencies understand the shared benefits of solar energy and work together to accelerate its deployment. Our outdated energy grid’s outages cost the U.S. economy $25 billion or more every year, according to a recent Morgan Stanley study using Department of Energy data. Recent extreme weather events have had devastating effects on our aging infrastructure and make a stronger case than ever to build a more resilient and reliable energy system. Distributed solar energy will help us to build that resilience and reliability, both for the nation and for individual owners of homes and buildings. Full Article:

Japan: The world's new star in solar power

Until recently less than 1% of Japan's electrical power output came from renewables. But following the catastrophe of Fukushima and the power blackouts that followed, Japan has seen an explosion in investment in alternatives. Solar, in particular, in this averagely photon-blessed country, has seen a seismic rise of late and is this year poised to become the world's largest solar market in volume after China. According to a report by energy analyst IHS on Japan's energy mix, Japan's solar installations jumped by "a stunning 270% (in gigawatts) in the first quarter of 2013." That means by the end of 2013 there will be enough new solar panels equal to the capacity of seven nuclear reactors. Such massive growth will allow Japan to surpass Germany and become the world's largest photovoltaics (PV) market in terms of revenue this year. "Japan is forecast to install $20 billion worth of PV systems in 2013, up 82% from $11 billion in 2012," IHS said. "In contrast, the global market is set for tepid 4% growth. The strong revenue performance for Japan this year is partly driven by the high solar prices in the country." Germany still leads with the total number of units and capacity, however, with its 32,192 megawatts. Japan is now closer to the U.S.'s 8,069 megawatts at 7,429 megawatts, according to London-based BNEF.

California Solar power generation hits record levels

With Southern California’s largest electric generating station broken and scheduled for removal, solar generation levels have reached a record level in California, state officials said Sunday. Solar power generation on California’s grid set a new all-time high output of 2,071 megawatts at 12:59 p.m. Friday, said officials at the California ISO, the state agency that balances customer demand on regulated power utilities with power generation from commercial vendors. That nearly equals the 2,250 megawatts of nuclear-powered generation that was lost in January, 2012, when small amounts of radiation began leaking from Southern California Edison’s San Onofre Nuclear Generating Station, at Camp Pendleton. San Diego Gas & Electric owns 20 percent of San Onofre, and has historically received one fifth of its power from the iconic nuclear plant, 65 miles north of San Diego. SDG&E has reassured its customers it can import sufficient replacement power from natural gas, wind and geothermal plants in the Imperial Valley via its new Sunrise Powerlink transmission line. The amount of solar energy generated on Friday was enough to power more than 1.5 million homes across California, Cal ISO officials said.

Innovative solar cell structure stores and supplies energy simultaneously

In a quest for a smaller, more self-sustaining solar power source, a UW-Madison electrical engineer has proposed a design for solar panels that can simultaneously generate power from sunlight and store power reserves for later, all within a single device. Hongrui Jiang and his students developed the idea, published in the journal Advanced Materials June 6. Jiang is the Vilas Distinguished Achievement Professor of electrical and computer engineering at UW-Madison and specializes in microscale devices. He and his students developed the technology as an offshoot of a National Institutes of Health grant to design a self-focusing contact lens that adapts to the eyes of adults suffering from presbyopia, a natural aging process that stiffens the lens and reduces the eye's ability to focus, especially at short distances. To power that contact lens, Jiang and his team have worked out a design that balances energy harvesting, storage and usage. "We needed a multi-functional and small-form-factor device in order to integrate it all into a single contact lens structure," says Jiang. The top layer of each photovoltaic cell is a conventional photo electrode, converting sunlight into electrons. During that conversion process, the electrons split off into two directions: most electrons flow out of the device to support a power load, while some are directed to a polyvinylidene fluoride polymer (PVDF) coated on zinc oxide nanowires. The PVDF has the high dielectric constant required to serve as an energy storage solution. "When there's no sunlight, the stored power will come back through the nano wires to power the load."

EU slaps levies on Chinese solar panel imports

The European Union announced Tuesday that it is imposing anti-dumping levies on imports of Chinese solar panels, in a move that could trigger a trade war between two of the world's largest economies. EU Trade Commissioner Karel De Gucht said the 27-nation bloc will impose a tariff of about 12% on the import of solar panels, cells and wafers from this week, increasing it to an average of 47% in August unless a settlement is reached with China in the next 60 days. China, the world's largest producer of solar panels, is accused by the EU of selling them below-cost — a tactic known as dumping — to corner the market. Its exports of solar panels to Europe totaled 21 billion euros in 2011. The cheap Chinese products are flooding the market and threaten to bring down EU manufacturers, De Gucht told journalists in Brussels. According to EU calculations, a fair sale price for Chinese solar panels should 88% higher than what they are currently being sold for.

A Floating Wind Tower Is Launched in Maine

One reason that offshore wind has not caught on in the United States is the steep cost of erecting a tower in the water, but researchers at the University of Maine tried another approach on Friday by launching a floating wind machine. It is the first offshore wind installation in United States waters, according to the Energy Department, which helped pay for it. The tower, launched in Brewer, Me., sits on three hollow concrete tubes and will be anchored in the Gulf of Maine. It is a mere 20 kilowatts in capacity, an amount of power that could be soaked up by a handful of big suburban houses on a hot summer day. But it is one-eighth the dimensions of the one the researchers hope to deploy in the next few years, a gigantic 6-megawatt model, with each blade as long as the wingspan of a Boeing 747. Because of its location, it will have two big advantages over machines on land, according to Habib J. Dagher, a professor of civil engineering at the university. Onshore wind machines produce most of their energy at night, when it is least valuable to utilities buying the power, but this one will catch the predictable, strong breezes that come up every sunny summer afternoon, he said, when the sun heats the land more than the sea, creating an onshore breeze.

Solar Industry Needs to Accelerate Growth to Impact Climate Change
